Embodiment Construction

[0015] The present invention relates to a method and system for aligning and attaching a suction ring to a patient's eye during ophthalmic applications involving the use of a laser system. Examples of possible laser systems that may be used with the present invention are those described in the following U.S. patent applications: Ser. Nos. 11 / 337,127; 12 / 217,285; 12 / 217,295; 12 / 509,412; ; Serial Nos. 12 / 509,211 and 12 / 509,454, each of which is incorporated herein by reference in its entirety.

[0016] Such laser systems may use an associated disposable patient interface device (PID) to align and immobilize the patient's eye relative to the laser, allowing effective delivery of therapeutic laser light to the cornea and lens , as well as enabling laser-processed images to be provided to the user to monitor the progress of the procedure. Like other ophthalmic ultrashort pulse lasers used to cut corneal or lens tissue, the PID has two parts: a suction ring, which is manually appli...

Abstract

An alignment device including means for releasably attaching a suction ring and means for applying a pattern of light to an eye of a patient. The alignment device further including means for detecting light reflected from the eye and determining whether the suction ring is aligned relative to the eye based on the detected light.

Description

[0001] This application is based on 35 U.S.C. §119(e)(1) claiming that the title of the invention submitted on February 1, 2010 is "Purkinjie Image-Based Alignment of Suction Ring in Ophthalmic Applications (Purkinjie Image-Based Alignment of Suction Ring in Ophthalmic Applications), which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to a method and system for aligning and attaching a suction ring to a patient's eye during ophthalmic applications. Background technique [0003] During intraocular lens (IOL) implantation, especially for accommodating or pseudo-accommodating IOLs, IOLs to correct for spherical aberration, or toric IOLs, an important factor in achieving optimal refraction is well-centered The anterior capsule is incised. This is because the surgeon uses the location of the capsular opening as a visual landmark for centering the IOL. Centering is important both optically and mechanically. Optically...
