After this lens has developed into a cataract and been removed, some new means of focusing your eyesight must be provided. The earliest means of focusing was cataract glasses, which are the least satisfactory method of restoring vision following cataract surgery. Cataract glasses are heavier, thicker and more bulky appearing than ordinary glasses. In addition, vision through cataract glasses is distorted. Objects with straight lines may appear bowed or curved and, since you cannot see well to the side, objects may loom suddenly into your peripheral field of vision.
Contact lenses are preferable to cataract glasses.
If you wear a contact lens on your eye following cataract removal, your vision will be much like it was before the cataract developed. Therefore, you may still need glasses for reading and close work. Although you can choose from both hard and soft plastic contact lenses, they still have drawbacks and risks. In addition, they can cause such symptoms as redness, excessive watering, sensitivity to light, or pain in the eye. Of all artificial lenses, implants simulate natural vision most closely.
