The Lens Implant
Lens Exchange alters the focus of the eye by removing the natural lens of the eye and replacing it with an artificial lens. This artificial lens is known as the Intra-Ocular Lens Implant. Eye surgeons call it the IOL.
The desired change in the focus of the eye is achieved by choosing a Lens Implant of the appropriate power. Measurements are performed on the eye before the operation and from these the optical power of the Lens Implant needed can be calculated. This process is called Biometry.

Intra Ocular Lens Implants are made from clinical grade plastics. The most popular Lens Implants currently used are made from pliable plastics. This enables the lens to be folded and inserted into the eye through a tiny incision, usually around 3 mms in length. Once within the eye the Lens Implant unfolds and can then be manoeuvred into position.
