CO2 laser-assisted deep sclerectomy

Abstract

CO2 laser-assisted deep sclerectomy (CLASS) is a procedure which enables an accurate dissection of the scleral wall and unroofing of the Schlemm's canal by utilizing the unique physical properties of the CO2 laser and its ability to ablate dry tissue with almost complete absorption of the energy by percolating aqueous humor. By this, it protects deeper tissues like the trabecular meshwork from the laser energy and avoids penetrating the anterior chamber (making this procedure practically an extraocular procedure). It has an excellent safety and efficacy profile and enables the surgeon and patient to enjoy the advantages of a procedure with a very short learning curve.
