Cataract is the clouding of the natural crystalline lens and typically occurs because of ageing, although other reasons may be prolonged use of steroids, exposure to ultra violet and
associated health problems like diabetes and eye injuries.
Surgery is the only known effective treatment for cataract removal. All cataract surgeries are aimed at removal of the cloudy natural lens and replacing it with an Intra Ocular Lens(IOL). At Amanat Eye Hospitals Phacoemulsification is performed ( No stitch surgery) and a foldable IOL is inserted. There are multiple IOL choices available for the surgery which are explained below. These lenses can be inserted through a small 1.8 to 2.8 mm opening
Aberration free/ Aspheric IOLS
These IOLs gives good quality of vision post operative due to the lens design, it also improves the contrast sensitivity of the patient and good night vision. These lenses also filter the harmful UV light and blue light which are said to be harmful to the retina.
These IOLs correct the pre existing corneal astigmatism there by reducing the possibility of spectacle wear for distant vision post operatively.
These IOLs provide clear vision for all distances hence almost 90% of the day-to-day activities can be performed without the need for additional glasses. Rarely the patient may experience glare during nights post operatively but usually gets adapted within a few months.
These IOLs have flexible hinges that enables them to change focus for different distances hence providing clear distance, intermediate and near vision without glasses.
