Cataract Surgery Q & A

What are cataracts?

Cataracts are a clouding of the natural lens and most often develop with age, but can develop earlier due to injury, certain medical conditions, or medication use. Your lens is located behind your iris, and it helps focus light onto your retina, which sends information through your optic nerve to your brain to create an image.

Your lenses are primarily made from water and proteins; over time, the proteins may deteriorate causing the lens to lose its’ clarity and become cataractous. This clouding alters the way your lenses focus light, leading to blurred vision.

Cataracts can affect one or both of your eyes and cause symptoms such as glare, difficulty with reading, computer use or driving.

What happens during cataract surgery?

Cataracts are irreversible and generally worsen over time, so the best solution is to replace them with clear artificial lenses. Modern cataract surgery, which has been around since the early 1980s, is one of the most successful surgical procedures, boasting a 98% success rate among the three million Americans who undergo the surgery each year.

Dr. Ted Lyu has extensive experience performing this procedure at their on-site surgical facility: the Brooklyn Eye Surgery Center. The facility has the latest technology for refractive and laser-assisted cataract surgery, including the Alcon Centurion System, LenSX Laser®, and ORA System®.

Thanks to this technology, the doctors can perform both standard and complex cataract surgeries, allowing them to replace your clouded lenses with intraocular lenses (IOLs) to restore your vision.

What types of intraocular lenses (IOLs) are available?

KLM Eye MDs offers standard as well as several premium IOLs to suit almost every need, including:


Toric lenses work well for patients with astigmatism, as well as near- and farsightedness. Your doctor can orient these lenses to give you the best vision possible and make you less dependent on glasses after your cataract surgery.


These specialty lenses offer multi-focal capabilities, allowing you to obtain distance as well as near vision and to reduce your need for reading or computer glasses after your cataract surgery.

Monofocal lenses

These lenses are single-focus and allow you to see distance after your surgery, but you may still need to rely on corrective eyewear for near reading vision.

Accommodating IOLs

These IOLs are more flexible, moving with your eye to allow more focus at a distance and close-up.
