LASES stands for 'Laser-Assisted Subepithelial Keratectomy, ' which is a type of eye surgery that uses a laser to reshape the cornea. This procedure is used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. It is a minimally invasive procedure that can be done in an outpatient setting and typically takes less than 30 minutes. The laser is used to remove a thin layer of tissue from the surface of the cornea, allowing light to pass through more easily and improving vision.
