When you have a cataract, the lens of your eye becomes cloudy. Light cannot pass through the lens easily, and your vision becomes blurred. During cataract surgery, the ophthalmologist (Dr.Rakesh shah,M.D.) removes the cloudy, natural lens and replaces it with a clear, artificial lens called an intraocular lens (IOL). The IOL helps your eye regain its focusing ability and allows you to see clearly again. The most common type of IOL is the monofocal or fixed-focus IOL. The monofocal lens helps you attain clearer vision at one distance. Note that eyeglasses and contact lenses are still required in order for you to see clearly at all ranges of distance. Another type of IOL is the multifocal IOL. The multifocal lens has several rings of different powers built into the lens. The part of the ring you look through will determine if you can see clearly at far, near, or intermediate distances.
