Patients are always surprised when shown a photograph of their own cataract, but then understand why it is that they don't see well. The natural lens is like a large Smarty or M&M - essentially a lens made of protein. When young this is completely clear, but with age the protein becomes hazy, yellow or brown. This change is called a cataract. As the person with a cataract looks through this murky material their vision is also blurred as a result.

Cataract surgery removes the cloudy lens and replaces it with a crystal clear artificial lens implant. This lens can correct long-sight, short-sight and even astigmatism. Sophisticated lenses such as the trifocal lens implant can allow patients to read without glasses.
The trifocal lens implant gives patients independence from glasses
