Abstract
Computer-implemented tools to assist a clinician in selecting a lens or other optical element for an optimal patient treatment, such as correction, based on both the optical properties of the patient's eye and certain patient-specific use-case information such as viewing behavior or viewing preferences, or to effect treatment such as to control myopia progression. Clinicians, eye care professionals and others can provide patient-optimized lens fitting or design by use of the tools.
Claims16
A method for selecting a treatment or corrective optical element for a patient, comprising:
- receiving an eye optical property information representative of optical properties of the patient's eye;
- selecting a set of one or more corrective optical elements from an optical element information source based upon the eye optical property information, wherein the selected set of corrective optical elements have optical property information within a range of the patient's eye optical property information, and wherein the optical element information source includes optical property information characterizing optical properties of each of a plurality of corrective optical elements;
- receiving a use case information representative of patient-specific viewing characteristics of the user, wherein receiving the use case information comprises receiving information representative of viewing behavior such as one or more of a patient-specific viewing distance, a patient-specific ambient light level, or a patient-specific viewing time;
- determining a use case optical property information based upon the use case information;
- selecting a subset of one or more of the optical elements of the set of optical elements based upon the use case information;
- determining a quality metric for each optical element of the subset based upon the eye optical property information and the optical property information of the optical element;
- and
- generating an optical element score for each optical element of the subset based upon the quality metric of the optical element.
