DESIGN PROCEDURE OF AN OPHTHALMOLOGICAL LENS THAT USES OPTIMAL FACTORS.

摘要

Procedure for designing an ophthalmic lens (10, 22), comprising: defining an error function indicative of the variability of performance of a lens in a patient population based on the estimated variability in one or more biometric parameters associated with said population, and selecting a form factor for the lens that reduces said error function with respect to a reference value, said form factor being defined as the ratio between the sum of the anterior and posterior curvatures and the difference of said curvatures, in an interval between -0.5 and 4.
