Single-focus lens
This lens gives clear sight at one distance, usually far. You would likely wear glasses for reading. This is the standard choice and works well for many people.
Astigmatism-correcting (toric) lens
If the front of your eye is shaped more like an egg than a ball (astigmatism), a toric lens corrects this. It can reduce your need for glasses for distance.
Multifocal lens
This lens helps you see near and far, so you may need glasses less. The trade-off is that some people see rings or halos around lights at night, and contrast may be a little lower. It does not suit every eye.
How to decide
Tell Dr. Kumar how you spend your day: reading, farm or shop work, driving at night, phone. Your eye health and cost matter too. He will tell you which options suit you and which do not. No lens can promise that you will never need glasses.
Honest risks
- All lenses: the same surgery risks as cataract surgery.
- The lens can move or tilt, rarely, and may need a second operation.
- Multifocal: halos, glare at night, less sharp contrast. Some people find them hard to get used to.
- Call us at once if: sight suddenly worsens, there is pain, or the eye turns red.
