Systems and methods for customizing adjustable intraocular lenses

摘要

The lens geometry and power of an intraocular lens is optimized to provide both distance and near vision correction for a patient. The optimization may be based on one or more measured accommodation-related parameters and one or more estimated accommodation-related parameters. An accommodative amplitude may be predicted based on the measured and estimated accommodation-related parameters, and the optimized the intraocular lens geometry and power established based thereon.

1. A method for customizing geometry and a focusing power of a fluid-filled intraocular lens comprising a shell to provide both distance and near vision correction for a patient, the method comprising:
a. determining a baseline amount of far-field focal correction for the patient; b. measuring at least one accommodation-related parameter for the patient; c. estimating at least one accommodation-related parameter for the patient based at least in part on statistical data; d. predicting an accommodative amplitude based on the measured and estimated accommodation-related parameters; and e. determining the intraocular lens geometry and a fill volume and an optical property of the filling fluid contained in the intraocular lens for providing a desired focusing power and accommodative level based at least in part on (i) the baseline correction, (ii) the predicted accommodative amplitude, (iii) a first relationship between the fill volume of the filling fluid and a lens pressure exerted by the filling fluid on the shell, and (iv) a second relationship between the accommodative level and the lens pressure exerted on the shell.
