The treatment of cataract as of today is by surgery. Medical management of cataract to dissolve the opacity of the lens and to make it clear is still in trial phase and it may be available in near future.
The types of surgery performed as of today are Phacoemulsification
with intraocular lens implantation
and small incision cataract surgery
with intraocular lens implantation.
Phacoemulsification, which is done through small incision measuring about 3.5 mm is the most commonly done and most preferred surgery for cataract because of early visual rehabilitataion.
The choice intraocular lens depends on the persons vision requirements and commonly includes foldable unifocal or multifocal intraocular lenses.
Since foldable intraocular lenses and phacoemulsification surgery is costlier, small incision cataract surgery with rigid intraocular lens is a cheaper and equally good alternative to phacoemulsification surgery.
