Abstract: Systems and methods for intraocular lens selection include obtaining one or more pre-operative measurements of an eye; selecting, from a plurality of historical IOL implantation records, a subset of historical IOL implantation records for evaluating a first plurality of prediction model candidates; evaluating the first plurality of prediction model candidates; selecting a first prediction model from the first plurality of prediction model candidates based on the evaluating; calculating, using the selected first prediction model, a plurality of estimated post-operative MRSE values based on a set of IOL powers and the one or more pre-operative measurements of the eye; determining a first IOL power corresponding to a first estimated post-operative MRSE value that matches a predetermined post-operative MRSE value; and providing the determined first IOL power to a user to aid in selection of an IOL for implantation in the eye.

Abstract: A system of visualizing a target site in an eye, using a polarization sensitive optical coherence tomography (PS-OCT) device, includes a controller having at least one processor and at least one non-transitory, tangible memory on which instructions are recorded. The target site is one or more vitreous opacities in the vitreous humor of the eye. The controller is configured to receive PS-OCT data and determine at least one parameter corresponding to birefringence properties of collagen fibrils in the vitreous humor based on the PS-OCT data. The at least one parameter includes respective spacing of the collagen fibrils. The controller is configured to determine a respective location of the one or more vitreous opacities when the at least one parameter is outside a predefined range and generate a control signal adapted for guiding a treatment beam at the respective location of the one or more vitreous opacities.

Abstract: An intraocular lens (IOL) configured to support a first optic for functioning as a single lens IOL and configured to support a second optic for functioning as a dual optic IOL. The base includes a first optic for providing a base power. A recess in an anterior rim of the base is configured for positioning a radial extension of a second optic. The geometry of the recess is configured to securely couple to the radial extension to prevent rotation of the second optic relative to the base and prevent tilting of the second optic relative to an optic axis.

Abstract: Systems, methods, and computer-readable media for integrating and optimizing a surgical suite. An ophthalmic suite can include a surgical console, a heads-up display communicatively coupled with a surgical camera for capturing a three-dimensional image of an eye, and a surgical suite optimization engine. The surgical suite optimization engine can performs a wide variety of actions in response to action codes received from the other components in the surgical suite. The surgical suite optimization engine can be integrated within another component of the surgical suite, can be a stand-alone module, and can be a cloud-based tool.

Abstract: A system and method for corneal cross-linking with real-time monitoring are provided. The method comprises determining a plurality of measurement locations in a region of a cornea, and applying a corneal cross-linking treatment to the region of the cornea. During the application of the corneal cross-linking treatment, the method also comprises acquiring a temporal OCT interferogram at each OCT measurement location, generating temporal complex OCT data based on the temporal OCT interferogram, determining biomechanical data based on the temporal complex OCT data, and adjusting the corneal cross-linking treatment based on the biomechanical data.

Abstract: A system includes an actuator, one or more items of diagnostic equipment configured to perform ophthalmic measurement, and one or more items of treatment equipment configured to facilitate performance of an ophthalmic treatment with respect to an eye of a patient. A controller is coupled to the actuator and is configured to cause the actuator to transfer the one or more items of diagnostic equipment and the one or more items of treatment equipment into and out of a region in front of an eye of the patient. The ophthalmic treatment may be a LASIK or SMILE treatment using refractive error and/or eye geometry measured using the diagnostic equipment.
