Ophthalmic laser surgical device for transepithelial laser refractive correction keratotomy

摘要

The laser ophthalmic surgical device relates to a laser module (12) having the function of emitting a focused pulsed laser radiation of variable pulse repetition rate and selection of one of several predetermined pulse repetition rates via user input. And a processor-based control unit (18) having the function of receiving at least one user input and controlling the laser module according to at least one selected pulse repetition rate. In certain embodiments, the user interface allows input of two user inputs, each of which relates to the selection of one of several predetermined pulse repetition rates. The control unit controls the laser module for the first stage of laser therapy according to one of the two user inputs and according to the other of the two user inputs for the second stage of laser therapy. Control the laser module. For example, such a specific embodiment allows epithelial tissue resection as part of a transepithelial keratotomy for the human eye at a different pulse repetition rate than stromal tissue resection.
