Lens Implant

March 10, 2018

During cataract surgery, the natural lens of the eye that turns opaque is removed, resulting in loss of focussing power of the eye. This situation would be similar to taking a photograph without a camera lens-pictures would be extremely blurred. When the natural lens of the eye is removed an artificial implant is placed in the eye (IOL).

Intraocular Lens (IOL)

IOLs are made of special quality acrylic material and can be folded and inserted via less than 2.8 mm incision. The different types of IOLs are:

>Monofocal IOL

Monofocal IOL

A monofocal intraocular lens can be used to give clear point focus either for far or near. Normally a patient is corrected for far vision and given additional glasses for reading purpose.

Aspheric IOL

Aspheric IOL

These are next generation monofocal IOLs having better contrast perception and reduced night time glare compared to plain monofocal IOLS. This helps in reducing glare during driving at night.

Toric IOLs

Toric IOLs

These lenses offer correction of high cylinders and provide excellent clarity in vision. These lens improve the overall quality of vision and are very useful for patients with astigmatism, keratoconus etc.

Multifocal IOL

Multifocal IOL

Multifocal IOLs correct not only far but also intermediate and near vision such as using computers/ tablets/ mobiles, cooking, and reading. They offer high quality glass free vision. Different types of multifocal IOLs are.

Multifocal IOL

Multifocal Diffractive IOLs

These IOLs, are designed with several optical zones on the lens surface. These zones have various focal points, allowing for an improvement in both far and reading vision.

Extended Depth of Focus IOLs

These are latest generation of IOLs having extended depth of focus, thereby allowing superior quality far and reading as well as intermediate (computer/ tablet) vision. Also they significantly reduce glare specially at night time.

Trifocal IOL

Trifocal IOL

Trifocal IOL is the newer generation of multifocal lenses. It provides excellent functional vision not only near and far, but also at intermediate. The advanced aberration correction optic design of trifocal lens provides:

  • Excellent vision at all distance - near, far and intermediate
  • Excellent vision in all light-conditions
  • No loss of contrast sensitivity.
  • High rate of spectacle independence.

How Do I Decide Whether To Have A Cataract Surgery?

  • Tell your Doctor how your cataract affects your vision & your life. You and your Doctor can decide accordingly.
  • I do not see well enough to do my best at work
  • I do not see well enough to do things I need to do at home.
  • I do not see well enough to do things I like to do. (E.g. T.V. sw, play cards, go out with friends.)
  • I am afraid I will bump into something or fall.
  • I am not as independent as I was earlier.
  • My glasses do not help me see clearly.
  • Driving is a problem at night and there is too much glare from headlights.
