Abstract Details


To estimate the efficacy of CO₂ laser-assisted deep sclerectomy surgery (CLASS) in patients with coexisting cataract and open angle glaucoma.


Ophthalmology Clinic Medical University of Silesia,RDH Katowice


15 patients ( 15 eyes) with open angle glaucoma and cataract were included. Fornix based conjunctival flap was created and half thickness sclera flap 4x4 mm was done. Next phacoemulsification of cataract with IOL implantation was perfomed. CLASS procedure with a CO₂ laser system (IOPtiMate OT-135P2- IOPtimaLtd., Israel) was performed. Intraocular pressure (IOP) was measured at baseline, 1, 2, 4 weeks, 3 and 6 months postoperatively. Complete success was defined as 5≤IOP≤18 mm Hg and 20% IOP reduction with no medication at a 6-month endpoint visit. Qualified success was defined as the same IOP range with or without medication.


Twelve patients completed 6 months follow-up. The mean baseline IOP of 24.2±1.7 mm Hg (mean±SD) dropped to 11.1±2.1 mm Hg at 6 months. An IOP reduction 29,8% was achieved at 6 months (P<0.0001). The mean number of antiglaucoma medications was reduced from 3.1± 0.4 at baseline to 0.3 ± 0.7 at last follow up visit. Intraoperative complications were mild with no sequelae. At 6 months follow up, complete success was achieved in 87% of patients, whereas qualified success was achieved in 100% of patients.


Short-term results show that CLASS may become a safe and effective treatment for patients with coexisting cataract and open- angle glaucoma.
