Presbyopic vision improvement

摘要

A method for designing a multi-focal correction for improving a person's presbyopic vision defect, comprising:
providing a multi-focal trial lens having an approximately correct distance defocus power for the person's eye;
making a wavefront aberration measurement of the person's eye with the trial lens in an optical measurement path at optical infinity and at an optical near point distance; and
using the wavefront aberration measurements to approximate a best form wavefront correction to be applied to the multi-focal correction so as to provide an optimum retinal image for the presbyopic condition.
