Objective: To evaluate the short-term of clinical safety and efficiency of CO2 laser-assisted sclerectomy surgery
(CLASS) in patient with open-angle glaucoma and complicated glaucoma. Methods: Our study involved 46 eyes of
46 patients with glaucoma that underwent CLASS and trabeculectomy respectively by the same surgeon (Zhaohui
Li) from May 2015 to January 2016 at the PLA General Hospital. Intraocular pressure and complications 1 week,
1 month and 3 months after operation was observed separately. Results: The intraocular pressure (IOP) 1 week, 1
month and 3 months after surgery decreased obviously (P=0.000). Compared to the trabeculectomy group 1 week, 1
month and 3 months after surgery, IOP of CLASS group was lower. But there was no statistically significant difference
between these two groups (P>0.05). There was no complication occurred in CLASS group. Early postoperative complications occurred in trabeculectomy group included shallow anterior chamber and choroidal detachment, and
they were all successfully resolved by pharmacotherapy. Conclusion: CLASS operation could reduce intraocular
pressure effectively and decrease the incidence of complications, such as postoperative shallow anterior chamber in
patients with glaucoma. However, its long-term effect and complications need to be further studied.
