How Lens Replacement Works

During your initial consultation, Mr Gangwani will test and then scan your eyes to make sure that you are a suitable candidate for the surgery. He will also talk to you about the procedure and the risks that might be involved and also go through a personalised plan with you.

Surgery is usually performed on one eye at a time. If you know that you’ll need surgery on both eyes, then the operations will be carried out 7-14 days apart. On the day of the surgery, you will be given anaesthetic eye-drops to numb the eye. This will make the entire procedure more comfortable.

The procedure typically takes 15-20 minutes but you may be in the hospital for pre and post-operative care for 3-4 hours, and you will be able to go home that same day.

Following your eye assessment, Mr Gangwani will recommend if you are a suitable candidate and suggest a personalised plan for your eyes to get the best outcome. He may suggest either enhanced monofocal, toric, trifocal or trifocal-toric implant depending on the structure and measurements of your eye.

Bifocals, Trifocals or Toric Lenses?

If you suffer from presbyopia or long-sightedness, then you will typically be recommended one of the above options. Bifocals are lenses which contain two lens powers. Trifocals, on the other hand, have three.

In bifocals, a small section of the bottom part of the lens contains all of the optical power you need to correct your vision for close-up objects. This is known as the near segment. When you look at trifocal lenses, you will soon find that they have a ribbon-shaped segment.

The power in this part of the lens will help you to see items which are immediately in front of you, or between 18-24 inches away. The rest of the lens will then be used for distance vision. Toric lenses are shaped in a very particular way.

Standard lenses have a spherical surface, much like the side of a beach ball. In a toric lens, you have a lens that is shaped like the side of a doughnut. The lens creates a very different refractive. It focuses on a horizontal and vertical orientation. The refractive strengths increase or decrease as you move your eyes.
