摘要： 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.

摘要： 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.

摘要： 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.
