The lens focuses the light rays coming from the pupil on the retina at the back of the eye where the image is created. The different part of retina collects the light and send a message to the brain through optic nerves enabling you to see. A cloudy lens is called cataract. Cataract surgery is the process in which the natural (which is cloudy) lens is removed and replaced with an artificial lens. In usual the lens of the eye is clear but a cataract causes the lens to become cloudy which eventually effects the vision. The cataract surgery is performed to eliminate the cloudy lens or it can also be detached with the laser technology. It’s a very common and generally a safe procedure.
Cataract causes blurry vision and increased glare from lights. When cataract makes it difficult for you to perform your regular activities the eye specialist suggest cataract surgery.
Nearly all the patients who have cataract surgery will be given the artificial lens called intraocular lens (IOL). This lens improves your vision. Variety of lens with different features are available. You need to discuss what type of lens should be inserted in your eye during the surgery. Lens are made up of plastic, acrylic or silicon. Some of the lenses require implantation through the incision and later are given stitches. Some of the lenses are flexible enough which requires few or no stitches. Types of lenses available include:
- Fixed – focus monofocal
- Accommodating-focus monofocal
- Astigmatism correction
