Near the front of the eye, the lens focuses light on the retina at the back of the eye. Light passes through it to produce a sharp image on the retina of the eye. When the lens of the eye becomes cloudy, light is unable to pass through it causing the vision to be blurred. This is known as cataract.
Surgery is the only way to remove cataract once it is formed. The operation involves making a small opening in the front surface of the eye, through which is put a small instrument that breaks the cataract up into smaller pieces that can be removed. After that a small clear plastic lens is put into the eye to replace of the cloudy lens.
The vision correction options include:
- Monofocal vision
- Blended vision
- Multifocal intraocular lenses
- Corneal astigmatism
