Abstract

A technique and apparatus are provided for simulating a laser treatment on the eye by pretreating a contact lens. A proposed laser treatment is developed using a patient's eye data. That laser treatment is then performed by an excimer laser system onto a contact lens blank. The lens blank is then placed on the patient's eye and the patient's resulting visual acuity are measured. If within acceptable limits, the treatment is then performed on the patient's eye. Otherwise, the treatment pattern is adjusted and the either original lens profiled with the difference or a new lens profiled with the new treatment pattern. This is repeated until the error falls within acceptable limits. Alternatively, spectacle lenses can be used instead of contact lenses.
