Abstract

The present disclosure provides a system that may: receive data associated with a plurality of locations associated with a cornea of an eye; adjusting at least one lens to set a diameter of the laser beam based at least on diameter information of the data associated with at least one of the plurality of positions; and for each of the plurality of positions: determining whether the eye has changed from a first position to a second position; if the eye has not changed from the first position to the second position, adjusting at least one mirror based at least on the position; if the eye has changed from the first position to the second position, adjusting the at least one mirror based at least on the position and at least on the second position; generating the laser beam; and directing the laser beam to the location for a period of time.

Description

[0001] background technical field [0002] The present disclosure relates to corneal cross-linking. Background technique [0003] In the past, corneal cross-linking (CXL) was used as a treatment for keratoconus. In this condition, the cornea of ​​the patient's eye thins and becomes weaker over time. Sometimes, another condition can cause a similar weakening of the cornea. The weakened cornea may bulge into a cone shape or some kind of irregular shape. The cone shape may distort the vision of the eye. If the cornea continues to weaken and / or becomes too thin, a corneal transplant may be performed on the eye. With CXL, doctors can use riboflavin and ultraviolet (UV) light to make the tissue of the cornea stronger. The source of UV light has always been UV lamps, and UV lamps can generate UV light for a certain amount of time. CXL can add bonds between the collagen fibers of the cornea. The bonds between collagen fibers can help stabilize the cornea. As the tissue of th...
