Why have an eye exam ?

Most eye disease is silent

Glaucoma

Hypertension

This is what we can see. Think of Kidneys and Brain.

Hemangioma – blood vessel tumor

Retinoblastoma – tumor in children

Indications for evaluation: A decrease in vision affecting the patients

quality of life. This may be evaluated by: Reduced Vision Debilitating glare Double vision Debilitating halos { I can’t drive at night} Do not want to wear glasses or contact lenses

A Brief History of Vision Correction

More Detailed Information Wavefront technology was originally

developed for use in high powered telescopes to reduce distortions when viewing distant objects in space.

This technology has now been applied to laser vision correction.
