Different types of lenses used in cataract surgery

Date: 19 Apr 2012   Group: Doctors    Category: Ophthalmologist   

My father has cataract in both eyes. The surgery of first one has to be done within one month. Doctors ask me to select a lense. But I do not have any idea about lenses and their effects. So please can any one tell me what are the different types of lenses, their effects and cost?

There are different types of cataract surgery. In the olden days there is intra capsular cataract extraction surgery was the thing commonly done in which whole the lens with the capsule is removed by large incision. The recent surgeries are extra capsular cataract extraction in which the incision is small compared to that and the posterior capsule is left intact to place the lens in the bag of the posterior capsule. There advanced surgery is the phacoemulsification in which incision is very small. The lenses used in the intra capsular cataract extraction are anterior chamber intra ocular lenses and iris supported lenses. The new type of surgeries use the following intra ocular lenses such as rigid, foldable and rollable types. The rigid is used in conventional extra capsular cataract extraction. The foldable in phacoemulsification and rollable in phacoknit which is more advanced surgery and it is costlier.

In cataract surgery, the natural lens has to be removed from the eye. In most cases a permanent intraocular lens (IOL) is implanted for replacing the natural lens in order to restore the focusing power. Traditional IOLs are monofocal, i.e. offer vision at one distance only (near, far or intermediate). But traditional IOLs mean that you must wear eyeglasses or contact lenses for reading for viewing objects etc. The new multifocal intraocular lens (IOL) offer the possibility of viewing at more than one distance, without using eyeglasses or contacts.
