    Abstract: Certain aspects of the present disclosure provide techniques for predicting a likelihood of future failure of components in an ophthalmic medical device and performing preventative maintenance on the ophthalmic medical device. An example method generally includes receiving, from an ophthalmic medical device, measurements of one or more operational parameters associated with the ophthalmic medical device. Using one or more models, a future failure of the ophthalmic medical is predicted. The predictions are generated based, at least in part, on the received measurements of the one or more operational parameters. One or more actions are taken to perform preventative maintenance on the ophthalmic medical device based on the predicted future failure of the ophthalmic medical device.

    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 range of a wavefront sensor (36) is extended by focusing collimated light onto a lenslet array (33), an output creating a grid formed by edges of the lenslets (34) and a reference spot in the members of the grid. Each referenc e spot has a known relationship to the grid member and a centroid. A relationship between the reference centroids is determined. Next a wavefront emanating from an eye is focused onto the lenslet array (33), with the outpu t from the lenslet array (33) forming the grid and aberrated eye spots thereon , each eye spot having a centroid. A relationship between the eye spot centroi ds is determined. One known relationship between one reference centroid and the centroid of one eye spot is identified. Finally, at least some of the remaining relationships between the reference centroids and the eye spot centroids are determined. The determined relationships provide a measure indicative of the eye aberration.

    Abstract: A method for optimizing a prescription for an ophthalmic implant includes the steps of receiving a measured correction prescription for a current patient having a classification element associated therewith, the prescription having been measured using wavefront determination. A database of treatment outcomes on a plurality of previously treated patients is accessed, each treated patient outcome having associated therewith at least one classification element and comprising a preoperative wavefront-determined correction prescription and a postoperative visual profile. From the treatment outcomes in the database is calculated an average difference between the preoperative prescription and the postoperative profile for at least some of the previously treated patients having a classification element in common with the current patient. Finally the current patient correction prescription is adjusted commensurate with the calculated average difference to form an optimized prescription, which is then transmitted automatically to an implant manufacturing device.

    Abstract: Un metodo para optimizar una prescripcion para el tratamiento de la cornea por ablacion con laser que incluye las etapas de recibir una prescripcion de correccion medida para un paciente actual que tiene un elemento de clasificacion asociado con el mismo, la prescripcion se ha medido utilizando una determinacion de frente de onda. Se tiene acceso a una base de datos de resultados de tratamiento en una pluralidad de pacientes previamente tratados, cada resultado de paciente tratado ha asociado con el mismo por lo menos un elemento de clasificacion y que comprende una prescripcion de correccion determinada de frente de onda preoperativa y un perfil visual posoperativo. A partir de los resultados de tratamiento en la base de datos se calcula una diferencia promedio entre la prescripcion preoperativa y el perfil posoperativo para por lo menos parte de los pacientes previamente tratados que tienen un elemento de clasificacion en comun con el paciente actual. Finalmente, la prescripcion de correccion de paciente actual se ajusta en proporcion con la diferencia promedio calculada para formar una prescripcion optimizada.

    Abstract: An optical correction system for correcting visual defects of an eye includes a wavefront analyzer responsive to a wavefront emanating from an eye for determining an optical path difference between a reference wave and the wavefront. A converter provides an optical correction based on the path difference and on a radially dependent ablation efficiency. The efficiency correction uses a compensating polynomial of the form A+Brho+Crho2+Drho3+ . . . +Xrhon, where rho is a normalized radius measured from a central portion of the cornea, reaching a value of 1 at an outer edge of the optical correction zone. A laser beam is directed to the cornea that has power sufficient for ablating corneal material. The optical correction is achieved by the removal of a selected amount of the corneal material to create a desired corneal shape change based on the optical correction.
