It is an additional use of Excimer Laser, during which removing tissue from the cornea helps the treatment of anterior surface clouding. This clouding is usually a result of an injury, inflammation and/ or of unknown etiology.
The technique demands preoperative research of the patient and assessment of the extent and depth of the clouding.
