What is a cataract, and why does Custom Vision Clinics see cataract surgery as an opportunity?

A cataract is an opacity that develops in the crystalline lens of the eye or in its envelope. Early on in the development of age-related cataract the power of the crystalline lens may be increased, causing shortsightedness (myopia), and the gradual yellowing and opacification of the lens may reduce the perception of blue colours. Cataracts typically progress slowly to cause vision loss and are potentially blinding if untreated.

Custom Vision Clinics see cataract extraction as an opportunity to create significant and long-lasting benefits to the patient. With this technique, many patients see better than they did, even before they developed the cataract.

IOL Counsellor

The IOL Counsellor is designed to allow you to see the benefits of IOLs for yourself. To use, simply drag the arrow slider from the left end to the right end to see the differences. At far left, you see "normal vision", move the slider to see how vision changes with presbyopia and cataracts. On the right side you'll see how the vision can be corrected with monofocal IOLs and with Presbyopia IOLs. To see a larger version of the IOL Counselor, click here.
