A cataract is a clouding of the lens inside the eye which leads to a decrease in vision. It is the most common cause of blindness and is conventionally treated with surgery. Visual loss occurs because opacification of the lens obstructs light from passing and being focused on the retina at the back of the eye.It is most commonly due to aging, but has many other causes. Over time, yellow-brown pigment is deposited in the lens, and this, together with disruption of the lens fibers, reduces the transmission of light and leads to visual problems.
Most patients are pleasantly surprised to find that their vision begins to improve a few hours after surgery. They may even find their vision better than ever. You will however need to wear glasses for reading and other activities. During the healing period, there may be some restrictions on strenuous activities.But most of our patients have returned to their normal lifestyle immediately.
Everyone will get cataracts if they live long enough. Cataracts can cause blurriness, poor night vision, or glare that gradually worsens if the cataracts are not removed.If cataract surgery is intended to correct distance vision in both eyes, and if one has normal depth perception, things should be fine following surgery. That said, many patients choose to have multifocal lens implants or to do monovision (having one eye set for near vision and the other for distance), and that could influence depth perception for near work. Regardless, details regarding expected outcomes should be discussed before surgery with the ophthalmologist.
