Abstract: Computer readable code adapted and configured to enable collection, annotation and sharing of digital ophthalmic images collected using a camera module on a mobile device or a hand held computer. The hand held computer can be used with a lens adapter configured to engage with a hand held computer device to allow a camera on the hand held computer device to take a high quality image of an eye.

Abstract: An advanced rasterstereography-based corneo-scleral topography (RCT) device includes an LED-based grid projection assembly, a grid image viewing assembly, and an optionally integratable front view camera assembly. The assemblies each include telephoto optical systems that provide a compact structure, an increased depth of field, and an increased field of view that allow sufficient acquisition of data in a single acquired image to provide the desired corneo-scleral topography analysis. The device utilizes a novel image processing algorithm. The device and method provide the capability to map a feature from a raw grid image onto a topography map of the corneo-scleral region, and to simultaneously display the images if selected by the user. The hardware, software, mechanical, electrical, and optical design considerations and integration provide advantages and benefits over prior RCT-type, Placido-based, and other conventional corneal topographers.

Abstract: The purpose of this invention is to provide a corneal topography system for use by eye car professionals to diagnose and correct vision defects; particularly, to an advanced corneal topography system which accurately assess the shape of the human cornea utilizing a projected grid and current digital camera technology.

Abstract: A method and apparatus related to enhancing corneal accommodation to address the effect of presbyopia. Corneal/scleral topology measurements in accommodating and non-accommodating states are indicative of a presbyopic subject's nominal corneal accommodative power. A desired accommodative power intended to improve on the effect of presbyopia can be determined, suggesting a selective biomechanical intervention in the corneal structure outside of the optical zone to create flexure regions. These flexure regions would allow enhanced corneal accommodation upon presentation of an accommodating stimulus. Intervention could be in the form of, for example, corneal surface ablation, intrastromal ablation, conductive keratoplasty (CK), laser thermal keratoplasty (LTK), and corneal and/or scleral implants. An improved topology measuring apparatus having an improved field of view and other attributes is disclosed.

Abstract: An intraocular lens, with equal conic surfaces, is intended to replace the crystalline lens in the posterior chamber of a patient's eye, in particular after a cataract extraction. The lens provides optical power to focus objects onto a patient's retina. In addition the lens surfaces are shaped to reduce optical aberrations at the retina and are tolerant to lens tilt and decentration within the eye. The lens is designed to have zero longitudinal ray aberrations at a specific ray height.

Abstract: The present invention relates to an intraocular lens, including a first lens having a first portion configured to alter light rays passing therethrough in a first manner and form a first image in an eye and a second portion adjacent said first portion. A second lens is coupled to the first lens and a third lens coupled to at least one of the first lens and the second lens. The second lens, third lens and second portion are configured in series such that the lenses from a telescope that alters light rays in a second manner and forms a second image in the eye.

Abstract: The present disclosure relates to an intraocular lens system. The lens system includes a first lens adapted to be positioned in the anterior chamber of the eye, along an optical axis, a second lens adapted to be positioned in the posterior chamber of the eye along the optical axis and in series with the first lens, and a third lens adapted to be positioned between the first and second lenses along the optical axis. The first, second and third lenses are configured to form a telescopic lens system.
