A clinical observation of carbon dioxide laser-assisted deep sclerectomy for Posner-Schlossman Syndrome

CLASS surgery provides effective and sustained IOP reduction in patients with refractory PSS. It demonstrates favorable structural and functional preservation of the optic nerve over the mid-term follow-up, with a manageable profile of minor complications. These preliminary findings suggest CLASS is a promising minimally invasive surgical option for this condition, though its long-term efficacy warrants confirmation in larger prospective studies.
