Problems solved by technology

[0013] Moreover, even if the condition is satisfied that the length of the cutting portion is set to be 2 mm or less, and the separation tool is moved with a skilled technique to separate the corneal stroma from the microlens, there is a problem that the larger the refractive abnormality is, the larger the corneal stroma is. The thicker the thickness of the cut lenticule is, when the lenticule of such a thick thickness is taken out from the corneal stroma, the two sides of the cut part are easily torn

Abstract

The present invention relates to a vision correction surgery laser adapter which creates a laser beam non-irradiated region. The disclosed invention relates to an adaptor of which the top is fixed toan object lens by having the center thereof meet the center of the object lens, and the bottom is fixed to a patient's cornea by having the center thereof meet the patient's cornea, in order to set the position of the patient's cornea with respect to the object lens of a laser. The adaptor comprises, on a non-refractive lens or refractive lens which is installed inside the adaptor and through which a laser beam of the laser downwardly penetrates, a pair of separated blocking units through which the laser beam does not penetrate.

Description

technical field [0001] The present invention relates to a laser adapter for vision correction surgery in which a laser objective lens is connected to a patient's cornea so that a laser beam irradiated from a laser used for vision correction surgery can accurately irradiate the patient's cornea. Background technique [0002] First of all, the purpose of the following background art is to help the understanding of the present invention, and the content mentioned in these background arts does not need to be regarded as the prior art. [0003] The cornea, the outermost surface of the eyeball, is the part of the eye through which light passes for the first time. It is transparent in color and is the tissue in front of the eye that refracts light to form an image on the upper part of the retina, from which the image is formed. The tissue at the back of the eye senses light and then transmits the signals from those images to the brain. [0004] On the other hand, as a method of co...
