Abstract
Purpose: To investigate the safety and efficacy of high-frequency deep sclerotomy combined with phacoemulsification in open-angle glaucoma patients with concomitant cataracts.
Materials and methods: Nine patients (mean age = 77 years) underwent combined high-frequency deep sclerotomy with phacoemulsification. The main outcome measures were intraocular pressure and the number of ocular hypotensive eyedrops. The results are presented as arithmetic means and standard deviations. The data were analyzed using Student’s t-test. Values of p < 0.05 were considered statistically significant.
Results: Mean preoperative intraocular pressure was 23.56 ± 2.7 mmHg. After 6 months, the follow-up average intraocular pressure was 16.89 ± 1.54 mmHg. Four patients did not require any topical glaucoma medication until their last follow-up. Five patients were able to reduce the number of intraocular pressure-lowering medications. The number of glaucoma medications was 2.44 ± 0.53 and 0.67 ± 0.71 before and after surgery, respectively. No serious complications were observed during the surgical procedure itself or in the postoperative period, with the exception of mild intraoperative hyphema.
Conclusion: Intraocular pressure after surgery was significantly lower than at baseline. A substantial proportion of patients was able to discontinue or reduce intraocular pressure-lowering medications. High-frequency deep sclerotomy combined with cataract surgery is a safe and effective minimally invasive procedure for the treatment of open-angle glaucoma.
