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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
