Dr. Arvind Varma is a practicing ophthalmologist who runs a clinic in Nerul, Navi Mumbai. Besides writing on common eye problems, Dr. Varma will also answer specific queries.

This issue Dr. Varma enlightens you about the surgical options for cataractous lenses.

How will I see if my lens is removed in the surgical procedure?
Nowadays a Cataractous lens is removed during surgery and replaced with an artificial lens (IOL) at the same time. Hence one gets comfortable vision after surgery. But for a perfect vision one may use glasses.

If you have opted for a surgery without IOL, you will have to use thick glasses.

What are the latest methods in Cataract removal?
Cataract can be removed by conventional method of ECCE surgery and IOL implanted. The size of incision is about 8-9 mm. Stitches are required after surgery. This method is widely practiced, is economical but needs more time for visual rehabilitation. It takes a few weeks before the patient returns to work.

Phacoemulsification is the other method wherein the lens can be removed through as small as about 3 mm cut and IOL can be inserted through the same cut. No stitches are required in such cases. This method is costly but visual rehabilitation is fast. Patient can return to his daily routine in a few days.

What are the types of IOLs available and how to choose the best?
IOLs may be used for placement in the front part of the eye (ACIOLs) or in the back part of the eye (PCIOLs). The lenses may be foldable for insertion through very tiny cuts. To further confuse you, IOLs may be monofocal or multifocal. Your operating surgeon is the best person to guide you and choose the lens for you.

Will my eye tolerate the IOL? What will happen if I rub my eyes hard with IOL in it?
IOL is an artificial implant and is well tolerated in most eyes. When well placed, it rarely causes any prolonged reaction. As the lens is placed deep in your eye, normal touch or washing or pressure on the eye does not affect it.

Can Cataract reoccur after surgery?
Once removed the Cataract never comes again. Sometimes the support left to place the PCIOL becomes opaque after years of surgery. This is known as After Cataract. It can be melted down in your Eye Specialist’s office with laser (this is in a matter of seconds).
