An optical equipment suitable for observation of an iridocorneal annular zone of an eye including: an illumination assembly, including at least one illumination electric device for illuminating the zone with a plurality of illumination optical paths for illumination light beams going to a corresponding plurality of sub-portions, an image capturing assembly, including at least one image capturing electric device for capturing images of the zone with a plurality of imaging optical paths for imaging light beams coming from a corresponding plurality of sub-portions, and a front optical assembly having a front surface located close to front surface of an eye, a rear surface located far from front surface of an eye, and including a central portion between the front and rear surfaces and a lateral portion around the central portion; the front optical assembly is stationary; all imaging optical paths pass through central portion between the front and rear surfaces.

Optical equipment for observation of the iridocorneal zone, methods of measuring and/or evaluating the iridocorneal zone

Systems and methods for designing and implanting a customized intra-ocular lens (IOL) is disclosed. In one embodiment, a system includes an eye analysis module that analyzes a patient's eye and generates biometric information relating to the eye. The system also includes eye modeling and optimization modules to generate an optimized IOL model based upon the biometric information and other inputted parameters representative of patient preferences. The system further includes a manufacturing module configured manufacture the customized IOL based on the optimized IOL model. In addition, the system can include an intra-operative real time analyzer configured to measure and display topography and aberrometry information related to a patient's eye for assisting in proper implantation of the IOL.

A fundus photographing apparatus includes: a photographing unit including a fundus illumination optical system to illuminate a fundus of a patient's eye and a fundus photographing optical system having a light receiving element to obtain a fundus image of the illuminated eye; and an alignment unit to position the photographing unit with the eye based on a predetermined alignment reference position. The alignment unit includes: an extracting part to extract, by image processing, an image region formed by reflection light from a portion other than the fundus from the fundus image obtained by the fundus photographing optical system; a gravity center calculating part to determine, by arithmetic processing, a gravity center position of the extracted image region; and a control part to perform alignment control of the photographing unit with the eye based on the calculated gravity center position and the alignment reference position.

An ophthalmic apparatus comprising: a fundus observation optical system; a designating part for designating an area of the fundus other than a macular area from a fundus image displayed on a monitor to make alignment of the fundus area of the fundus image displayed on the monitor with the fixation target displayed on a LCD display; a judging part for detecting an approaching state of the fixation target projected on the fundus and the designated fundus area based on positional information of the fundus area designated by the designating part on the monitor after movement and positional information of the fixation target displayed on the LCD display, and judging based on a detection result, whether or not the designated fundus area and the fixation target projected on the fundus are coincident in a predetermined allowable range; and a display control part for changing the display state of the fixation target based on a judgment result of the judging part.

Ophthalmic apparatus

Described herein is a method for optimization of the conditions of execution of the vision contrast test and the corresponding system with which to implement said method so as to be able to guarantee optimal conditions throughout the test session even when not it is not possible to respect the standards. Furthermore, the method comprises a self-calibration procedure, which definitively eliminates the operations of calibration of the system by specialized centers.

The following is a method to represent images for dissociative stereoscopic vision, which allows, by means of some simple operations on stereoscopic images, to develop a device comprising a processing card and LCD shuttering goggles, which together with a computer equipped with a graphic card with LVDS output and any image display device, enable to perform visual acuity tests on patients.

Method to represent images for dissociative stereoscopic vision and related system

An apparatus for imaging an eye can include a pair of Scheimpflug imaging systems. Each Scheimpflug imaging system can have respective video cameras and optics configured to direct light reflected from an eye into the video cameras. The apparatus can also have a movable platform configured to move the pair of Scheimpflug imaging systems in accordance with eye movement detected by an eye tracking imaging system. In some embodiments, the Scheimpflug imaging systems can rotate 90 degrees about an optical axis of an eye being examined.

Dual Scheimpflug system for three-dimensional analysis of an eye

The present invention relates to a novel instrument for the examination of an eye, namely the retina. The instrument features a LCD display for projection of various types of patterns and stimuli via an optical system onto the retina. The retina can be visualized by live IR image sequences as well as by visible light still frame images. It combines five examination types within one instrument, namely a perimetry examination, a microperimetry examination, a fixation stability examination, a scotoma boundary detection and psychophysical examinations.
