Abstract
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.
Claims23
A method for customizing an intraocular lens geometry and power 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 power based at least in part on the baseline correction and the predicted accommodative amplitude.
A system for customizing an intraocular lens geometry and power to provide both distance and near vision correction for a patient, the system comprising:
- a measuring system for (a) determining a baseline amount of far-field focal correction for the patient and (b) measuring at least one accommodation-related parameter for the patient;
- a memory for storing a database comprising accommodation-related statistical data;
- and
- a processor in operative communication with the measuring system and the memory, the processor being configured to (a) estimate at least one accommodation-related parameter for the patient based at least in part on statistical data;
- (b) predict an accommodative amplitude based on the measured and estimated accommodation-related parameters;
- and (c) determine the intraocular lens geometry and power based at least in part on the baseline correction and the predicted accommodative amplitude.
