Cataract surgery evolved in the last 2 to 3 decades. Initially when we used to perform cataract operation the whole cataract was removed from within the eye through a very large incision which is almost about 8 to 10 mm inside. After removing the cataract, we were taking stitches to close the incision and a riches lens was implanted in India. Now the technology as evolved and performed the cataract operation just 2 mm incision and this incision is also made either with laser or with diamond instrument. Once cataract is emulsified or liquefied inside the eyes. It is sub out and it become almost like water after removing this cataract the lens implanted in the eye from this lens is special foldable lens and it passes through the same 2 mile meter incision and it unfold him inside the eye. There are different types of lens which are available: They could either unifocal lens which allows you to see very fear very clearly and for reading you have to reading glasses. The Other lens which is available is multifocal lens and did in multifocal lens.
