Contact lenses are an option for correcting visual defects in some patients. Refractive eye surgery procedures change the shape of your cornea to help the eye focus better and may reduce or eliminate the need for glasses or contact lenses. You may be a candidate for refractive surgery if your eyes are healthy and your eyeglass prescription is stable. In some cases it may be necessary for the patient to use glasses after surgery. Phacoemulsification is a method of extracapsular extraction using a high frequency ultrasound device to fragment the lens into small particles which are then aspirated.
Cataract surgery can be sutureless and with topical or retrobulbar anesthesia.
There are little or no restrictions after surgery which is done on an outpatient basis. A corneal transplant is the replacement of a scarred or diseased cornea with clear corneal tissue from a donor. There is no need to match the donor and recipient by eye color, age, sex, or blood type. The Eye Bank Association of America has a national database that helps provide donor corneas to those surgeons and patients who need them. Most corneal transplants are performed under local anesthesia as an outpatient procedure.
