Abstract
A Bayesian model for predicting spectacle independence of one or more IOLs based on pre-clinical data (e.g., visual acuity value for one or more defocus values) of an IOL. The Bayesian model is trained to assign appropriate weights for different combinations of defocus values.
Claims14
An optical system configured to select an intraocular lens (IOL) from a plurality of IOLs for manufacture or for implantation into a patient eye, the selected IOL configured or manufactured to improve post-surgical spectacle independence outcome for the patient, the system comprising:
- a processor configured to execute programmable instructions stored in a non-transitory computer storage medium;
- and
- a population database comprising clinical data for a plurality of patients implanted with one of the plurality of IOLs, the clinical data comprising information related to spectacle independence for a plurality of values of visual acuity between about −0.2 log MAR and about 1 log MAR at various defocus conditions between about −5 D and 0 D, wherein the information related to spectacle independence is based on responses of the patients implanted with one of the plurality of IOLs to a questionnaire,
- wherein the processor is configured to:
- calculate for each of the plurality of IOLs, a probability of being spectacle independent for visual acuity equal to a threshold value between about −0.2 log MAR and about 1 log MAR at at least one defocus conditions between about −5 D and 0 D based on the information related to spectacle independence obtained from the population database;
- and
- identify one of the plurality of IOLs having a higher probability of being spectacle independent for manufacture or for implantation into the patient's eye.
An optical system configured to identify an intraocular lens (IOL) that will improve post-surgical spectacle independence, the system comprising a processor configured to execute programmable instructions stored in a non-transitory computer storage medium to:
- calculate a probability of achieving spectacle independence for at least two IOLs based on clinical data providing visual acuity at a first defocus position for the at least two IOLs in a population of patients implanted with one of the at least two IOLs;
- and
- identify one of the at least two IOLs having a higher probability of achieving spectacle independence.
A system for predicting post-surgical spectacle independence of one or more IOLs, the system comprising a processor configured to execute programmable instructions stored in a non-transitory computer storage medium to:
- calculate a probability of achieving spectacle independence for the one or more IOLs based on clinical data providing visual acuity at one or more defocus position for the one or more IOLs in a population of patients implanted with one of the one or more IOLs.
A method of manufacturing an IOL comprising:
- receiving one or more parameters of an IOL selected from a plurality of IOLs based on calculating a probability of achieving spectacle independence for the plurality of IOLs from clinical data providing visual acuity at one or more defocus position for the plurality of IOLs in a population of patients implanted with one of the plurality of IOLs;
- and
- manufacturing the selected IOL.
