A cataract is a clouding of the transparent lens of the eye. As the lens becomes increasingly opaque, light rays entering the eye are prevented from focusing on the retina. Symptoms include blurred vision, sensitivity to light and glare, distortion and dimming of colors and vision. Cataracts are generally associated with aging but may also be caused by medications, trauma or diseases such as diabetes. During cataract surgery, the cloudy lens is removed and replaced with an artificial intraocular lens.
Geneva Eye Clinic offers several choices in intraocular lenses including toric lenses such as the AcrySof and Tecnis to correct astigmatism and monovision which can reduce the need for glasses full time. Presbyopia correcting lenses such as ReSTOR and ReZoom help provide greater visual freedom and good range of vision from distance to near.
