Abstract

An ophthalmic lens treatment planning System receives lens and ophthalmic lens treatment information from a customer lens order, identification of available equipment to apply ophthalmic lens treatment(s) from the customer order, and performance and parameters of the available equipment. The ophthalmic lens treatment planning System formulates an optimal ophthalmic lens treatment plan to be implemented by the available equipment to apply the ophthalmic lens treatment(s) from the customer order to the lens. Following application of the optimal ophthalmic lens treatment plan to the lens, the resulting lens may be measured to provide last run results and the last run results may be fed back to the ophthalmic lens treatment planning System to provide further performance and parameters of the available equipment to the ophthalmic lens treatment planning System.
