How is cataract surgery performed? Is it safe?

At Shahzad Eye Hospital, cataract surgery is performed using state-of-the-art equipment.

A micro-incision is made to access the lens, which is then removed using phacoemulsification (ultrasonic power). A new intra-ocular lens (IOL) is placed in its place to give the patient perfect vision.

The procedure usually lasts between 15-30 minutes.

Does cataract surgery hurt?

What kind of intra-ocular lenses (IOL) are there? What is difference in surgery with different IOLs?

There are many kinds of IOLs. Hard IOL: these are non-foldable IOLs and require a larger wound to insert the lens. This requires longer rehabilitation. These require glasses for near vision after the operation. Foldable IOL: these are the most commonly used IOLs. These require a much smaller wound to insert and rehabilitation is much faster. These give a better quality of vision after the operation. These require glasses for near vision after the operation. Foldable IQ IOL: this is also a foldable IOL. This lens blocks the UV light entering there and therefore causes less damage to the retina in the long term. This is also requires a small wound and rehabilitation is much faster. These require glasses for near vision after the operation. Toric IOL: these lenses are usually foldable IOL. The also correct the astigmatism in the eye. Multifocal: these lenses correct vision after the operation in a way that no glasses are required for near or distance after the operation.
