Cataracts (Cloudy Eye Lens) Types, Causes, Symptoms, Pictures | Healthhype.com Home » Current Health Articles » Cataracts (Cloudy Eye Lens) Types, Causes, Symptoms, Pictures Cataracts (Cloudy Eye Lens) Types, Causes, Symptoms, Pictures Tweet Light enters the eye through the transparent cornea and passes through the pupil, the diameter of which is determined by the iris. It then passes through the lens of the eye which bends the light (refraction) to focus it on the back of the retina. The image projected on the retina stimulates receptors that transmits signals to the brain. For visual acuity, all these structures need to be clear and functioning optimally in a manner that allows it to be focused accurately. What is a cataract? A cataract is a clouding of the lens of the eye that causes progressive loss of vision over time. It develops gradually and since it is painless, it can take months to years before any change in vision is actually noticed. Cataracts are a common abnormality of the eye that is seen mainly in older people, although it can occur in younger patients when associated with certain diseases. The lens is a unique structure in the human body.

It has to be firm yet flexible, transparent and refract light (bend light) and constantly vary in shape to allow for visual acuity. Broadly the lens is composed of three layers : an outer capsule (lens capsule) a thin epithelial layer in the middle but only on the anterior surface (front) of the lens (lens epithelium) the inner fibers which are elongated cells with an extensive cytoskeleton (internal skeleton) that constitute the bulk of the lens (lens fibers) The lens also has specialized crystalline proteins that are capable of transmitting and refracting light. Furthermore the cells of the lens lack the conventional organelles which may disrupt the transmission of light. Normally in the human eye , light passes through the lens and is bent (refraction) so that all beams of light are focused on a single spot on the retina. This creates a clear image. With a cataract, some light beams are blocked either partially or completely, diffused or distorted. Ultimately this means that a clear coherent image does not fall on the retina. The extent of the visual disturbance depends on several factors including the location, size ad severity of the clouded part of the lens.

The entire lens is usually not affected simultaneously in a cataract but instead an area or areas of the lens are gradually compromised. The reason why the lens becomes opaque is complex and there are several mechanisms accounting for the different types of cataracts. Overall, cataracts are the leading cause of blindness globally. Types and Location of Cataracts There are broadly three types of cataracts based on the location of the opacity in or on the lens. Nuclear cataract where the opacity is in the center of the lens (nucleus). This occurs as a result of sclerosis (abnormal hardening) of the lens with accumulation of urochrome pigment causing the lens to become yellow or brown. Cortical cataract where changes in the hydration and ionic composition in the cortex of the lens causes an opacity in the edge of the lens. The internal structure of the lens may even liquefy causing a hypermature or Morgagnian cataract. Posterior subcapsular catarct where the opacity is at the posterior (back) of the lens due to plaque formation or migration of the lens epithelium to the posterior surface. Causes of Cataracts Cataracts can be broadly classified as acquired or congenital.

Most cases of cataracts are acquired during the course of life while a small number is congenital meaning that it is present from birth. In terms of congenital cataracts, it may arise with diseases during the fetal stage of life or from in-born errors of metabolism that may lead to systemic changes including cataract formation. Acquired cataracts may occur as a complication of other diseases (secondary cataract) or injury to the eye (traumatic cataract). Most cataracts are due to age-related changes. The formation of cataracts in the elderly (senile cataracts) is probably due to a multitude of factors seen with aging – diminished regenerative properties, oxidative damage, hardening of the lens and any systemic illnesses. Other causes and risk factors include : Injury to the eye Chronic use of certain prescription drugs including corticosteroids Excessive exposure to UV light or x-rays Poor nutrition Systemic diseases like diabetes mellitus, galactosemia, Wilson’s disease, atopic dermatitis Signs and Symptoms The symptoms of a cataract may develop gradually over time and usually remains unnoticed for long periods until the visual disturbances become prominent. Regular ocular examination by an opthalmologist may help with early detection.

The main complaint is cloudy vision or blurred vision which may also be dim. This is a result of the opacity blocking or diffusing the light as it passes through the eye. Patients may also complain of a number of other visual disturbances such as halos, glare or double vision . Ask a Doctor Online Now! Loss of visual acuity in bright light or when keeping the gaze at a fixed distance like when reading is seen mainly with posterior subcapsular cataracts. With nuclear cataracts, patients may report a short term improvement of near vision but eventually clouding, blurring and a gradual loss of vision sets in. Cataracts are painless lesions of the lens, however, a rise in intraocular pressure (glaucoma) seen with certain causes may result in eye pain.

Cloudy vision is the loss of visual acuity or a dimming of visual perception that can affect one or both eyes. You may experience cloudy vision as a haziness or lack of clarity in your eyesight.

Cloudy vision may also dull your color perceptions, and it is often accompanied by glare or halos around lights. Cloudy vision may result from simple, harmless causes, such as discharge from the eyes or tearing, or it may result from serious causes such as trauma to the eye. Although the term cloudy vision is sometimes used to describe blurred vision, these two changes in vision are slightly different. Blurred vision is most often caused by refractive error, which is corrected by eyeglasses or contact lenses to give you sharp vision. The most common cause of cloudy vision is cataract, which is a gradual loss of transparency in the lens inside your eye. Most cataracts develop as part of the aging process and are seen more frequently in older people, although cataract may develop earlier as a result of injury, diabetes, or prolonged use of certain drugs, including corticosteroids. Looking for a Doctor? Search Now Find a Great Eye Doctor Near You Changes in or damage to the cornea, the clear “window” covering the front of your eye, may also cause cloudy vision. Although the cornea is a small structure, it is essential to good vision because all of the light rays that enter your eye pass through the cornea.

Cloudy vision originating in the cornea may be caused by chemical burns, trauma, infections or inflammations of the cornea (keratitis), and numerous corneal dystrophies (conditions that cause abnormal buildup of fluid or other substances in the cornea). 10 Things Your Eye Doctor Wants You to Know Less common causes of cloudy vision include diabetes, optic nerve disease, and macular degeneration. Because your eyes and vision are vital to your quality of life, it is important for you to contact your health care practitioner if you develop cloudy vision or any other eye symptoms that cause you concern. Occasionally, cloudy vision can be a sign of a medical emergency. Seek immediate medical care (call 911) if you experience cloudy vision as a result of chemical injury or trauma or if cloudy vision occurs along with other serious symptoms such as eye pain or sudden change in vision or blindness, sudden weakness or numbness on one side of the body, severe headache, or fainting, lethargy, or a change in level of consciousness. Seek prompt medical care (call 911) if your cloudy vision is persistent, increasing, or causes you concern. Cloudy Eye in Cats Cloudy Eye in Cats Written by: Dr.

Noelle McNabb Edited by: Dr. Rhea Morgan Last Modified: August 04, 2015 Share This Article Read by: 296,278 pet lovers Overview of the Feline Cloudy Eye A cloudy eye or increased opacity of the eye is associated with reduced transparency of either the cornea, the fluid media within the eye, or the lens. This change may be described as a "film" covering the cat's eye or as an increased cloudy "whiteness" to the cat's eye. Cloudiness of the eye may or may not be associated with a reduction in vision. The causes of a cloudy eye in cats typically fall into one of the following categories: Cloudiness of the cornea, which may occur with corneal infections, corneal scarring, infiltrative inflammatory diseases of the cornea, fatty infiltration within the cornea, or corneal edema (fluid accumulation) Cloudiness of the aqueous humor, which is the fluid that circulates within the front chamber of the eye. This may be due to the accumulation of white blood cells, protein, fatty lipids or blood. Opacification or whitening of lens from cataract formation.

Disorders of the vitreous body, which is a gelatinous fluid between the lens and retina. These may include hemorrhage or inflammation. What to Watch For Physical change in the appearance of one or both eyes Possible decrease in vision with changes in behavior Possible squinting. Some causes of a cloudy eye are painful; others are not. Possible discharge from the eye Possible redness to the eye Diagnosis of Cloudy Eye in Cats Diagnostic tests are essential in determining the precise cause of the cloudy eye. Tests may include: Complete medical history and physical examination Complete ophthalmic examination including fluorescein staining of the cornea, Schirmer tear test, tonometry, slit-lamp biomicroscopy and indirect ophthalmoscopy. Complete blood count (CBC) and biochemistry serum tests Additional diagnostic tests may include: Cytology, or microscopic examination of any inflammatory changes in the cornea Bacterial culture of an infected cornea Aspirate and analysis of any cloudy fluid from within the eye Ultrasound examination of the eye if the retina cannot be examined Gonioscopy of the normal eye if glaucoma is suspected. This uses an optical instrument called a gonioscope to examine the angle of the anterior chamber of the eye.

Certain serologic tests for infectious diseases Treatment of Cloudy Eye in Cats Successful treatment depends on obtaining an accurate diagnosis as to what tissue of the eye is cloudy and what is the underlying cause of the problem. Home Care Optimal treatment for your cat requires a combination of home and professional veterinary care. Follow-up examinations can be critical to your cat's health. Also, do not delay in bringing your cat to the hospital for initial examination as some causes of a cloudy eye may result in a loss of vision within a very short period of time. In addition, do the following: Observe the eye at least twice daily. Signs that may indicate a worsening condition include more obvious inflammation (redness), increased or altered discharge from the eye, pain (usually evident as squinting) or loss of vision. If your cat's vision is compromised, minimize stress and risk of injury by confining him/her to a safe area until the cause of the problem is determined. Do not allow your cat to rub or self-traumatize the eyes. To prevent self-inflicted damage you may need to obtain a protective collar (called an Elizabethan collar or E-collar) from your veterinarian.

Do not administer human over-the-counter medicines such as Visine or other ophthalmic products designed to "reduce eye redness" or irritation as the underlying cause of the problem must be identified. Administer all medications as prescribed and alert your veterinarian if you have any difficulty treating your cat. Protect Your Pet Mind if we pay your vet bills?

In-depth Information on Cloudy Eyes in Cats Numerous changes in the cornea of the eye may result in cloudiness, including: Corneal ulceration or infection from bacteria, fungi or yeast Corneal scarring from congenital defects of the eyelids; inrolling of the eyelids; exposure of the cornea to foreign bodies, drying, heat, smoke, chemicals; eye injury or trauma; inability to blink properly and protect the eye; decreased sensation on the surface of the cornea and resulting poor protection of the cornea; prior corneal surgery Corneal inflammation from inadequate tear production (keratoconjunctivitis sicca; dry eye syndrome), certain forms of keratitis, etc. Corneal lipid deposition that may arise with other chronic corneal diseases Invasion of the corneal with tumor cells (rare) Development of corneal edema associated with age or with premature degeneration of the cornea, from glaucoma, in association with inflammation of the interior of the eye, secondary to prior surgery of the cornea, etc.

Numerous changes in the front chamber and fluid of the eye may cause visible cloudiness: Cloudiness of the fluid in the front chamber from inflammation (uveitis), hemorrhage, trauma, or leakage of fatty material into the eye (from the blood stream) Movement of the lens into the front chamber, particularly if the lens has developed an opaque cataract or is causing corneal edema Collapse of the chamber with movement of the iris towards the front of the eye (secondary to penetrating trauma, lens movement, glaucoma, etc.) Growth of tumor from the iris into the front chamber Changes of the lens that cause cloudiness in the eye include: Cataract formation Nuclear sclerosis (age-related lens hardening resulting in an 'opalescent' color change to the lens) Changes of the vitreous that may cause obvious clouding of the eye include: Vitreal opacities (floaters) that accumulate with inflammation around or within vitreous Hemorrhage into the vitreous Detachment and forward movement of an opaque retina into the front of the vitreous (?) It is essential that a specific cause be identified in order to initiate appropriate therapy.

In general, opacities of the eye that develop suddenly, reduce vision, and/or cause pain (rubbing eye, squinting) are inherently more serious and necessitate immediate medical attention.

Diagnosis In-depth The following diagnostic tests are essential in helping to diagnose and treat your pet's ocular disease: Complete medical history and physical examination Complete ophthalmic examination including slit-lamp biomicroscopy (magnified examination of the eyelids, cornea, front chamber of the eye and lens) and indirect ophthalmoscopy (magnified examination of the vitreous body and retina) Schirmer tear test to determine if tear production is normal, elevated or reduced Fluorescein and rose bengal staining of the cornea to detect surface defects, ulcers and erosions Tonometry (measurement of the pressure within the eye) to evaluate for the presence of glaucoma Complete blood count (CBC) and serum tests to evaluate the cause and identify any related problems Tests for feline leukemia virus (FeLV), feline immunodeficiency virus (FIV), feline infectious peritonitis virus, and toxoplasmosis Additional diagnostic tests may be recommended based on results of initial tests or due to a lack of response to prior treatments. These tests may include: Corneal cytology (complete cell analysis) of cell samples collected from infected or inflamed corneas to determine the presence of infectious organisms and type of inflammatory reaction.

Corneal culture of cells collected from corneal ulcers to identify the specific type of bacteria or fungi present and which antibiotics they are most susceptible to. Tests for feline herpesvirus infection if certain corneal diseases are present. Paracentesis (collection of a fluid sample from the anterior chamber or vitreous body obtained with a small needle) is an alternative for attaining a diagnosis of undefined uveitis (or cancer) utilizing cytology and serology. Serology (testing of antigen-antibody reactions in-vitro) when systemic fungal (cryptococcosis, blastomycosis) infections are suspected. Electroretinography (evaluates the electrical responses of the retina to light stimulation) to ensure that the retina is functioning normally. Ultrasound examination of the eye (imaging technique in which deep structures of the eye are visualized) when the eye is too opaque for normal examination procedures. Treatment In-depth Therapy in cats is dependent upon the underlying cause (diagnosis). (?) Cataract Surgery and Vision Correction | Eugene Eye Care Schedule a Consultation Cataract Surgery and Vision Correction Welcome to Eugene Eye Care, the office of Drs. Ofner, Neale, Bordewick, and Fleming.

We are pleased to introduce you to the art of cataract surgery, and explain how the removal of your cataract represents an opportunity to improve your vision. Your Vision Before we go on, take a moment to consider your vision. Just as every person is unique, every person’s vision is unique. Some are blessed with excellent vision from birth, and are able to function without corrective lenses of any kind. Others are born with eyes that require corrective lenses such as contacts or glasses from an early age. Regardless of whether or not you have needed glasses before, when cataracts are removed, the playing field is leveled. If you have needed strong glasses all your life, you will likely be less dependent on them after surgery. However, even if you did not need glasses before, there is a chance that you may need them after surgery! On this web page, we will explain how the use of glasses can be minimized or even eliminated through modern surgical techniques. Reading Glasses At the age of about 45 everyone begins to experience a condition known as “presbyopia,” or the need for reading glasses. For those who already wear glasses, bifocals become necessary. For those lucky few who never needed glasses before, reading glasses usually become necessary.

Since most patients who visit our office with cataracts are seniors, the concept of presbyopia is all too familiar. However, cataract is a condition that affects people of all ages. If you are younger than 45 years old, or if you have never needed reading glasses it is especially important for you to grasp this concept. After your cataracts are removed, your vision will change and you WILL experience the need for corrective lenses to help you see things that are up close. If you would like to be less dependent on glasses after your cataract procedure, read on: we will explain in detail the options that are available to you. What is a Cataract? An eye without cataract can see clearly. The majority of patients that we see in the office are a little unclear on exactly what a cataract is. To understand, think of your eye like a camera. When light enters a camera it is focused by a lens. Much like a camera, your eye also has a lens. The lens in your eye starts out clear, but becomes increasingly cloudy as time passes. When this cloudiness reaches a certain point, instead of focusing light, the lens scatters light!

Usually, it happens so slowly that patients don’t even notice until the condition is very advanced! Eventually, however, most people notice problems with hazy vision, glare, and difficulty driving at night. It is at this point when patients are ready to seek help. Cataract causes light to scatter, resulting in blurry vision. Although cataracts can happen at any age, any person who is blessed with long life will eventually develop a cataract. In fact, 3 million Americans undergo cataract surgery every year, making cataract surgery the most common surgical procedure in America. Although this procedure is safe, as with any medical procedure, the only guarantee that can be made is that your surgeon will do his or her absolute best to give you the most excellent vision possible. After the cataract has been removed, we have a unique opportunity to customize your vision. This is not a one-size-fits-all solution. Every patient has different needs, and each eye is unique. We can help you make this choice after talking with you and examining your eyes. This web page will introduce the options available now, before you consult with your surgeon, so that we can all make the most of our time together.

Vision Correction In order to restore vision, we must not only open a path for light to enter the eye—we must bend that light to a sharp focal point. When a cataract is removed, we are faced with the task of focusing light into the eye. To obtain a clear point of focus, a corrective lens is always required; this lens can be placed in front of the eye (as is the case with glasses), on the surface of the eye (a contact lens), or it can be implanted permanently inside the eye. Although ALL patients who undergo cataract surgery now receive an implanted lens, many patients ALSO require glasses to fine tune their vision as well. The reason for this is that the prescription in the implanted lens must be predicted BEFORE surgery. Once in the eye, the lens implant is permanent and cannot easily be changed! Although our predictions are fairly accurate, about 30% of the time, patients will need some further correction to see well enough to pass their driver’s’ test. Therefore, it is important that we develop a plan for how your vision will be fine-tuned after surgery. This plan may be as simple as the expectation of wearing glasses.

However, if wearing glasses is something you would like to avoid, options exist to correct your vision with less dependence on glasses. Expectations In days gone by, cataract surgery was only done in cases of severe vision loss. The surgery was risky, required hospitalization for a week or more, and the recovery of vision could take months; even then, very strong glasses were usually required to see. Nowadays, the bar is set much higher. We aim to not only safely remove the cataract in an efficient and painless procedure, but we also desire to quickly restore your vision in such a way that dependence on corrective lenses may be minimized or eliminated. One of the most important factors in achieving a successful surgical result is for me as your surgeon to make sure that your expectations are within the realm of what I can provide using the available surgical techniques and technology at my disposal. Nearly every patient with cataract knows someone who has already gone before them. Most folks say, “I am nervous to have my eyes worked on—but at the same time I am looking forward to seeing better.

My neighbor had cataract surgery and now he doesn’t wear glasses.” While not wearing glasses is a common outcome of cataract surgery, it is not attainable for everyone to go without glasses. If your expectation is to achieve a glasses free lifestyle, we definitely need to discuss how you and I will go about meeting those expectations! Stop and consider what your expectations are regarding what your vision will be like after your surgery. It doesn’t matter what your vision is like now—this procedure puts everyone on an equal footing. If you need glasses now, you may not after surgery. If you do NOT need glasses now, please realize that you may become dependent on glasses unless we develop a specific plan to achieve the result you desire! Setting Vision Goals Consider the following questions: Do you currently wear glasses for distance activities like driving or tennis? Do you currently depend on glasses for near activities like reading labels or using the computer? Would you like to be less dependent on glasses after your procedure? If the answer to the last question is yes, then we should set some goals for your vision. Your surgeon’s role in this process is to compare your expectations with what can reasonably be attained using the surgical tools available.

Your vision counselor’s role will be to analyze your insurance benefits to determine what the monetary cost of achieving our goal will be. You will then weigh the benefits against the costs and let us know what level of vision correction best meets your needs. We will now explain some of the options we have available to make your surgery the most enjoyable experience possible. We will also introduce the concept of setting goals for your vision so that you will be able to select the vision correction plan that best meets your needs. Overview of Surgery Options We have several levels of care to choose from. To make things understandable, we have ranged these options in order from good, better, and best: Plan Level: Silver Goal: A modern surgical experience with the understanding that glasses will be needed to see clearly for driving and reading. The vast majority of silver patients will not need to buy or use any prescription eye drops after surgery. Silver patients will receive a care package of useful supplies including sunglasses, reading glasses, and soothing natural lubricant eye drops. Although glasses will likely be required since no specific vision correction is planned, a glasses prescription is included with this plan.

An important benefit to the silver plan is the inclusion of advanced diagnostic eye imaging tests which help to exclude the possibility of undiagnosed eye diseases such as glaucoma, macular degeneration, or astigmatism. Plan Level: Gold Goal: An improved surgical experience targeting excellent distance vision without glasses, understanding that glasses will be needed for reading. At the gold level, patients enjoy all the benefits of the silver plan. Additionally, the gold plan includes distance vision correction. Specialized surgical techniques will be used to target excellent distance vision. Even in rare cases where these methods do not immediately yield the desired result, your surgeon will use sophisticated tools to fine tune your vision after surgery to the point where you will be able to engage in distance activities such as driving and watching TV without glasses. Plan Level: Platinum Goal: An improved surgical experience targeting excellent vision for driving and reading without the aid of glasses. This comprehensive vision correction plan is available only to select patients whose eyes are very healthy, and who have no medical eye problems other than cataract. Inclusive of all the benefits of the gold level, platinum patients will be minimally dependent on glasses, being able to achieve excellent distance and near vision without correction.

Similar to the gold package, this plan allows for the possibility of additional vision enhancing procedures without incurring additional charges if the goal of good distance and near vision is not immediately forthcoming. Summary So to review, we have 3 levels of vision correction for you to choose from. Ranging from silver to platinum, each plan offers an additional benefit to your vision. The Silver plan includes advanced diagnostic imaging, reduces the need for eye drops after surgery, and includes a care package; with the Gold plan corrected distance vision is targeted, and with the Platinum plan, a goal is set for excellent distance and near without glasses. Our aim is to assist you in obtaining your best possible vision. Please call us to set up a consultation any time at 541-687-1715. After your consultation with your surgeon, you will meet with a vision counselor who will analyze your insurance benefits so that you can make an informed decision on which plan is right for you.

During cataract surgery, the cloudy lens inside the eye is removed and replaced with a clear artificial lens implant. The cataract is surrounded by a clear cellophane-like wrapping. During cataract surgery, the front cellophane wrapping is removed. Then the cataract is removed and the implant placed. The back cellophane wrapping (known as the posterior capsule) remains intact. In some people, months or even years after cataract surgery, this clear cellophane membrane becomes cloudy. Subsequently, laser treatment is done to restore vision. Symptoms Decrease in vision is the main symptom which begins anywhere from a few months to many years after cataract surgery. Also, increased difficulty with glare and bright lights as well as decreased ability to read and see far distances.

Treatment Treatment involves a brief two minute procedure in which a laser is used to create an opening in the clouded membrane. A laser is a focused beam of light. The procedure is completely painless and is completed with numbing eye drops. There are no eye drops to use after the procedure and most patients resume all normal activity immediately. Most patients notice an improvement in vision within the first day or two. An invisible laser (shown in green) is focused onto the cloudy membrane behind the lens implant where a small hole is created. This allows light to pass freely to the retina and thereby improves vision. Above Left: The circular object is the lens implant. A small spring-like device is at the left of the implant. Behind the lens is a cloudy membrane. The cloudy haze can be seen through the center of the lens implant. Above Right: A hole in the center of the cloudy membrane is seen through the lens implant. Since light can now pass easily, vision is improved. Get Connected Cloudy Eye in Dogs Cloudy Eye in Dogs Written by: Dr. Noelle McNabb Edited by: Dr.

Numerous changes in the front chamber and fluid of the eye may cause visible cloudiness: Cloudiness of the fluid in the front chamber from inflammation (uveitis), hemorrhage, trauma, or leakage of fatty material into the eye (from the blood stream) Movement of the lens into the front chamber, particularly if the lens has developed an opaque cataract or is causing corneal edema Collapse of the chamber with movement of the iris towards the front of the eye (secondary to penetrating trauma, lens movement, glaucoma, etc.) Growth of tumor from the iris into the front chamber Changes of the lens that cause cloudiness in the eye include: Cataract formation Nuclear sclerosis.

This is an age-related lens hardening resulting in an 'opalescent' color change to the lens Congenital defects in the blood vessels around the lens Changes of the vitreous that may cause obvious clouding of the eye include: Congenital defects of the front portion of the vitreous Vitreal opacities (floaters) that accumulate with inflammation around or within vitreous Hemorrhage in to the vitreous Detachment and forward movement of an opaque retina into the front of the vitreous (?) Cataract Treatment | Cataract Surgery Manchester MA | Gloucester MA Home / Treatments & Conditions / Eye Conditions / Cataracts Cataracts occur as part of the normal aging process. Studies show that virtually everyone over age 65 has some cataract formation in their eyes! Cataracts can severely reduce your vision. At one time, cataracts were a leading cause of blindness in the world. But today, fortunately they can be treated. Modern surgical techniques, intraocular lens implantation and "same day surgery" make cataract surgery safe, fast and effective. A cataract occurs when the normally clear lens of the eye becomes cloudy.

As the cataract develops, the cloudiness no longer allows the lens to properly focus light on the back of the eye. This unfocused light causes the vision to look blurry or hazy. Development of cataracts has been associated with exposure to ultraviolet radiation. They are particularly prevalent in persons who spend a lot of time in the sun, such as fisherman. There is nothing you can do to prevent the formation of cataracts. Treatment is indicated when decreased vision affects your everyday activities or hobbies. Cataract surgery, in which the normal cloudy lens is removed, is now a very successful procedure. The most widely used technique is called phacoemulsification. A very small incision is made and a tiny ultrasonic probe is used to break up the cataract and gently suction it away. A clear membrane is left in your eye where an intraocular lens is placed (IOL). This IOL is necessary to replace the focusing power of the natural lens, which was removed. With insertion of an IOL, there is little need for thick cataract glasses and contact lenses that were used years ago. Small incision surgery has several benefits. The procedure is very quick, sometimes taking less than 20 minutes.

Also, recovery time is short. Patients are able to eat a light snack and drink immediately after the surgery. The results of the surgery are almost immediate. Most people notice an improvement in their vision soon after surgery. You will still need glasses to read after the surgery. Your new prescription is given a few weeks after the procedure. Cataract Surgery and Lens Implantation The eye is a marvelous optical instrument which takes the images from the real-world and focuses them on a tiny spot in the back of the eye. The ability to focus these images comes from two parts of the eye, the lens of the eye and the front cover of the eye, or the cornea. The lens accounts for about 1/3 of the focusing power. The Natural Lens is Removed During Cataract Surgery: A cataract occurs when the lens of the eye becomes cloudy so that it can no longer focus the real-world images. Patients with cataracts see the world as very hazy, because light cannot pass freely through the lens to be focused on the back of the eye. The only way to remove a cataract is to remove the lens itself. Cataract Surgery Procedure: Cataract surgery is a procedure that removes the cloudy lens from the eye.

Today, this procedure can be accomplished very quickly and no stitches are needed. A local anesthetic is used and the surgeon makes a small incision in the outer covering of the eye. Then a technique is used, called phacoemulsification, which removes the lens through the small incision. At least 99% of the patients receive an artificial lens implant after the cataract is removed. This lens is called an intraocular lens or IOL and is made from the same plastic as certain types of contact lenses. In some cases, a special tiny foldable IOL is used for implantation. This type of lens is inserted into the eye through a very small opening, only 1/8th inch. Once in the eye, the lens unfolds to its full size. The IOL replaces the 1/3 of the eye's focusing power of the natural lens. Without this lens, the eye cannot focus. In a small number of cases, an IOL is not used and the patients must wear glasses or contact lenses to help them see. IOLs are beneficial because they are permanent in the eye. They do not get lost, like glasses, or have to be replaced, like contact lenses.

Also, many times the focusing power of the IOL can be determined so that it closely matches your eye. With an IOL, glasses for distance vision may not be needed. This cataract surgery technique has many benefits. No hospital stay is needed, there is no pain, no injections are required, there is quick recovery and the vision after surgery is typically very good. Are There Any Risks? Cataract surgery and IOL implantation is quite safe. The IOLs must pass through a very stringent approval process before they can be used. The benefits of the implant greatly outweigh the small added risk of implantation. As with any surgery, complications can occur. There is a possibility of hemorrhage or infection. Your eye doctor will discuss potential complications of cataract surgery and lens implantation with you. Multifocal or Accommodative Intraocular Lens (IOL) Implants Crystalens™ The Bausch & Lomb Crystalens™ is a cataract replacement lens (IOL) that works naturally with muscles in the eye to retain the eye`s ability to accommodate or shift focus between nearby and distant objects after cataract surgery.

It is the first FDA-approved accommodating lens.Â With other IOLs, patients lose this ability and require corrective measures such as glasses or contact lenses. With Crystalens can treat both cataracts and presbyopia. Unlike rigid lenses, the flexible silicone Crystalens features hinges that allow it to move with the eye`s muscles and accommodate seamlessly, thereby reducing or eliminating the need for vision correction. The Crystalens is implanted using the same, nearly risk-free cataract surgery techniques as with other IOLs. Most people with cataracts or who have had corneal refractive surgery and retained good eye health are acceptable candidates for Crystalens implantation, but those who have already had cataract surgery are not. People with eye health problems such as chronic infections or diabetes should check with their doctors about eligibility. ReSTOR® Lens Flexible IOLs have been used for years to help patients enjoy clear vision after cataract surgery. The advanced ReSTOR® lens improves upon ordinary IOLs by providing a full range of focusing distances. A series of 12 gradual "step heights" create seamless focusing ability from near to far, while the edge of the IOL enhances distance vision.

A feature called apodization also helps the eye distribute light evenly in different lighting conditions. Best of all, up to 80% of patients who use the ReSTOR® lens don't need glasses or contact lenses after surgery. Toric IOL Toric IOLs are specially designed for patients with astigmatism. Traditionally, surgical correction of astigmatism required making a series of small incisions (called LRIs) around the cornea to make it more spherical instead of football-shaped. Implanting toric IOLs often improves vision due to astigmatism without the need for these extra incisions, and also allows patients to enjoy a faster, more comfortable recovery. Posterior Capsulotomy What is the Capsule? The natural lens of the eye is held in place by a thin clear membrane called the lens capsule. The capsule completely surrounds the lens and separates it from the thick fluid in the back of the eye, called the vitreous, and the thinner fluid in the front of the eye, called the aqueous. Cataract Surgery Effects the Capsule: Cataract surgery is necessary when the natural lens become cloudy and must be removed.

When cataract surgery was originally performed, surgical techniques were not as refined as today, and both the natural lens and the capsule were removed during surgery. Newer techniques allow the capsule to remain in the eye and hold the implanted lens (or intraocular lens, IOL) in place. Leaving the capsule in place during surgery is a great advancement because it allows the vision after surgery to be more stable and provides for less surgical complications. Sometimes the posterior, or back, portion of the capsule becomes cloudy after cataract surgery. The reasons for this cloudiness are unknown. If the posterior capsule becomes so cloudy that it detrimentally effects vision, then a capsulotomy is performed. What is a Capsulotomy? A capsulotomy is a procedure in which an opening is created in the center of the cloudy capsule. The opening allows clear passage of the light rays and eliminates the cloudiness that was interfering with the vision. A laser beam is used to create this opening. This procedure is painless, very safe and typically the results can be seen immediately. For capsulotomy, as with any surgery, rare complications can occur, such as swelling or retinal detachment. These complications can cause loss of vision.

A cloudy capsule will many times appear the same way as the original cataract. The vision is cloudy or hazy and the patient is heavily bothered by glare. In fact, vision is so similar that some patients think that the cataract has come back or regrown. This is impossible, cataracts cannot return once the natural lens has been removed. If your vision is getting worse after cataract surgery, it could be that your capsule is becoming cloudy. Your eye doctor should give you a thorough eye examination to determine the cause of your vision loss. If your capsule is becoming cloudy, your eye doctor can then determine whether a capsulotomy is necessary to improve your vision.
