A cataract is an opacity (or cloudiness) in the lens of the eye. This restricts light passing through the eye and reaching the retina. When this occurs, vision is affected.
COMMON SYMPTOMS OF CATARACTS ARE:
THE MOST COMMON CAUSE OF CATARACTS IS AGING.
Others include:
Cataract ( Motibindu ) Surgery
Modern cataract or lens replacement surgery is one of most successful surgeries known. It is effective in restoring vision to most patients. The surgeon makes a tiny incision on the side of the cornea, removes the eye’s clouded natural lens after dissolving it (using a procedure known as Phacoemulsification) and then replaces it with an artificial ‘Intraocular Lens’ (IOL). Because the incision is very small, stitches are not required and the eye heals quickly, allowing the patient to return to routine lifestyle within a week. Modern cataract surgery is a safe outpatient procedure that barely takes about 10 minutes. Newer advancements such as whitestar phaco (cold phaco) and microincisional phaco emulsification (MICS) have increased its safety even further.
An Intraocular Lens (IOL) is the replacement lens that is surgically implanted in the eye to replace the existing natural clouded lens during cataract surgery.
The design of IOL decides your need for spectacles after the surgery. Newer advanced IOL (Toric, Multifical and Accomodative) can treat cataract and get rid of spectacle power too.
A standard mono-focal IOL has one point of focus, which is usually distance vision. If you choose standard IOLs, you will generally need glasses for near activities like reading. On the other hand, if your mono-focal IOLs are focused on near vision, you would need glasses to see distant objects clearly.
