    Abstract: An ophthalmic lens includes an optic having an anterior surface with an anterior surface radius of curvature (R1) and a posterior surface with a posterior surface radius of curvature (R2). The anterior surface radius of curvature (R1) and the posterior surface radius of curvature (R2) define a shape factor (X) (where X = (R2-R1)/(R2+R1)) that is greater than zero. The shape factor (X) corresponds to a curve defining shape factor (X) as a function of lens power (P), the curve monotonically decreasing with increased lens power (P).

    Abstract: A system and method for selecting an intraocular lens, for implantation into an eye, includes a controller having a processor and a tangible, non-transitory memory on which instructions are recorded. The controller is configured to selectively execute a machine learning model trained with a training dataset. Execution of the instructions by the processor causes the controller to obtain pre-operative objective data for the patient, including one or more anatomic eye measurements. The controller is configured to obtain pre-operative questionnaire data for the patient, including at least one personality trait. The pre-operative objective data and the pre-operative questionnaire data are entered as respective inputs to the machine learning model. A predicted subjective outcome score for the patient is generated as an output of the machine learning model. The intraocular lens is selected based in part on the predicted subjective outcome score.

    Abstract: Un sistema para predecir el viñeteo postoperatorio en el ojo de un sujeto incluye un controlador con un procesador y una memoria tangible no transitoria donde se registran las instrucciones. El controlador se comunica con un módulo de diagnóstico adaptado para almacenar datos anatómicos preoperatorios del ojo como modelo ocular. El sistema incluye un módulo de proyección y un módulo de trazado de rayos, ejecutables selectivamente por el controlador. El módulo de proyección está adaptado para determinar las variables postoperatorias imputadas del ojo basándose, al menos parcialmente, en los datos anatómicos preoperatorios y la lente intraocular. El módulo de trazado de rayos está adaptado para calcular la propagación de la luz a través del ojo. El módulo de trazado de rayos se ejecuta para determinar la distribución de la luz para los respectivos ángulos del campo visual a lo largo de un campo de visión predefinido. El controlador está configurado para determinar uno o más parámetros de viñeteo postoperatorio basándose, al menos parcialmente, en la distribución de la luz.

    Abstract: A system and method for selecting a preferred intraocular lens, for implantation into an eye, includes a controller having a processor and a tangible, non-transitory memory on which instructions are recorded. The controller is in communication with a diagnostic module adapted to store pre-operative anatomic data of the eye as an eye model. The controller is configured to determine respective imputed post-operative variables for each of a plurality of intraocular lenses, via a projection module. A respective pseudophakic eye model is generated for each of the plurality of intraocular lenses by incorporating the respective imputed post-operative variables into the eye model. A ray tracing module is executed in the respective pseudophakic eye model to determine at least one respective metric for the plurality of intraocular lenses. The preferred intraocular lens is selected based on a comparison of the respective metric.

    Abstract: A method (400) of verifying ophthalmic measurements includes obtaining (402), via an ophthalmic measurement device (102), a first measurement of at least one ophthalmic parameter over a first measurement area (202). The first measurement area corresponds to an unassisted visible area of a patient's eye (104). A second measurement of the at least one ophthalmic parameter over a second measurement area (302) is obtained (406) via the measurement device (102). The second measurement area (302) corresponds to an assisted visible area of the patient's eye (104). The first measurement is compared (408) to the second measurement. It is determined (410) if the second measurement diverges from the first measurement. Responsive to a determination that the second measurement diverges from the first measurement, an alert that the second measurement is inaccurate is generated (414). Responsive to a determination that the second measurement does not diverge from the first measurement, the second measurement is accepted as accurate (412).
