A docking method for an ophthalmic system may include the steps of aligning a docking unit of the ophthalmic system and an eye; generating an image of an internal structure of the eye by an imaging system; improving an alignment of the docking unit with the internal structure of the eye in relation to the generated image; and docking the docking unit to the eye. The generating the image step may include computing scanning data by a processor corresponding to a scanning pattern; storing the scanning data in a data buffer; transferring the scanning data by the data buffer to ...
An imaging-guided docking system can separate the tilt and location of an imaged ophthalmic target and present them in an intuitive manner for an ophthalmic surgeon. The docking system can include an ophthalmic imaging system to image a portion of an eye of a patient, an image processor to determine a location and an orientation of the imaged portion of the eye, and a guidance system, coupled to the ophthalmic imaging system, to guide an ophthalmic docking based on the determined location and orientation. In some implementations, the imaging system images an internal eye-structure to determine its orientation and a ...
A laser system for ophthalmic surgery includes a laser source, to generate a pulsed laser beam, an XY scanner, to receive the pulsed laser beam, and to output an XY-scanning beam, scanned in two directions transverse to a Z axis, a Z scanner, to receive the XY-scanning beam, and to output an XYZ-scanning beam, scanned in addition along the Z axis, the Z scanner including a first lens group to output a beam having an intermediate focal plane, and a movable lens group to receive the beam through the intermediate focal plane and to collimate the beam in a variable ...
Techniques and systems for gradient search are provided based on sensing or measuring at selected locations of a target object without performing full-field sensing or measuring over the entire field of the target object. Search methods are provided to include determining a coordinate of a boundary of a region in relation to a loop in a proximity of a first location, determining a direction of a gradient of the coordinate corresponding to the first location, and selecting a second location based on the determined direction. A search system can be implemented to include an imaging system to determine a coordinate ...
Purpose: To evaluate and compare thickness changes in the retinal layers in the macula with optical coherence tomography (OCT) segmentation software after femtosecond laser–assisted phacoemulsification (study group) and conventional phacoemulsification (control group).Setting: Department of Ophthalmology, Semmelweis University, Budapest, Hungary.Design: Case-control study.Methods: Total retinal thickness of the macula was evaluated using Stratus OCT 4 to 8 weeks postoperatively. The OCT images were segmented using OCT retinal image analysis software. Regional thickness data in the central area, inner rings, and outer rings were obtained and absolute and relative thicknesses of the individual retinal layers in the 2 study ...
LenSx is in Laser Cataract Surgery company. LenSx was acquired by Alcon in 2010. LenSx uses femtosecond technology with the discipline and passion necessary for success. The LenSx system represents a culmination of extensive, research and intense development. Our fully integrated, image-guided femtosecond laser platform enables surgeons to perform the key steps of cataract surgery with efficiency and precision. The LenSx Laser is a customizable, 3-D surgical platform that performs anterior capsulotomy, corneal incisions and lens fragmentation in a single step, delivering unmatched reproducibility and predictability.
