Description
Background: Medmont Studio software has a feature that can predict the fluorescein pattern of a
gas permeable contact lens using a patient's topography. It has been proposed by Medmont that lenses can be ordered empirically by using the projected fluorescein pattern instead of using a diagnostic lens. Methods: Twenty eyes were fit in one of eight gas permeable lenses and the fluorescein pattern was photographed using an anterior segment camera. The actual fluorescein pattern was then compared to the projected fluorescein pattern of the lens on the patient's cornea using the Medmont software. Results: In eighteen out of twenty eyes, Medmont software accurately predicted the actual fluorescein pattern. In the two eyes that the predicted and actual fluorescein patterns did not coincide, smaller than average horizontal visible iris diameter played a role. Conclusions: Medmont Studio software is able to accurately predict fluorescein patterns on eyes with average parameters. For most eyes, Medmont Studio software is a viable option for empirically ordering gas permeable lenses. The software may significantly decrease the number of diagnostic lenses tried before a successful fit is achieved and significantly decrease chair time for the optometrist. |
