摘要： A laser eye surgery system includes a laser to generate a laser beam. A topography measurement system measures corneal topography. A processor is coupled to the laser and the topography measurement system, the processor embodying instructions to measure a first corneal topography of the eye. A first curvature of the cornea is determined. A target curvature of the cornea that treats the eye is determined. A first set of incisions and a set of partial incisions in the cornea smaller than the first set of incisions are determined. The set of partial incisions is incised on the cornea by the laser beam. A second corneal topography is measured. A second curvature of the cornea is determined. The second curvature is determined to differ from the target curvature and a second set of incisions are determined. The second set of incisions is incised on the cornea.

摘要： In an ophthalmic laser surgical system, a real-time optical coherence tomography (OCT) measurement method acquires OCT data during laser treatment. The treatment laser beam and OCT sample beam are generated simultaneously, and the optical delivery system scans them simultaneously in the eye tissue, where the focus of the treatment laser beam and the focus of the OCT beam coincide with each other in space. While both beams simultaneously scanned in the eye tissue, the OCT device detects returned OCT light from the sample during a data acquisition period, and generates an OCT A-scan based on the detected OCT light. Based on the A-scan, a controller determines a structure of the eye in a depth direction relative to the focus of the OCT beam, and controls the operations ophthalmic laser surgical system accordingly. One exemplary application is the formation of an arcuate corneal incision in cataract surgery.

摘要： A laser eye surgery system includes a computer which scans a focused laser beam in a trajectory over a reticle or target and determines beam quality via laser light reflected from the target. The target may have a grid pattern of lines, with the diameter of the focused laser beam determined based on a time interval for the scanned beam to move onto a line of the grid pattern. Methods for measuring beam quality in a laser eye surgery system provide a direct, quantitative quality measurement of the focused laser beam, and may be performed quickly and automatically. Using scanning mirror position information together with signals resulting from laser light reflected from the target, the laser eye surgery system may also be calibrated.
