Cataracts occur when there is a buildup of protein in the lens that makes it cloudy. This prevents light from passing clearly through the lens, causing some loss of vision. Cataract leads to decrease in vision, Difficulty in recognising people,difficulty in driving, reading etc.It also leads to decrease in contrast sensitivity.Treatment of cataract
Early cataracts cause mild impairment of vision and a suitably prescribed spectacle can give a good vision. However if the cataract causes difficulty in routine activities it needs to be operated.Cataract is emulsified by phacoemulsification surgery and an intra ocular lens is then implanted.Types of Intraocular (IOL) Lens Monofocal Lens
Monofocals are set to provide best corrected vision at near, intermediate or far distances.Multifocal or Accommodative Lenses
In the multifocal type, a series of focal zones or rings is designed into the IOL. Depending on where incoming light focuses through the zones, the person may be able to see both near and distant objects clearly.Which lens option is right for you?
Before surgery your eyes are measured to determine your IOL prescription and compare options to decide which IOL type is best for you
