Visual prognosis, intraocular pressure control and complications in phacomorphic glaucoma following manual small incision cataract surgery

摘要

Aims:To evaluate intraocular pressure (IOP) control, visual prognosis and complications following manual small incision cataract surgery among eyes with phacomorphic glaucoma.Materials and Methods:This prospective, non-randomized interventional consecutive case series included all patients with phacomorphic glaucoma who presented to a tertiary eye care referral center in South India between March 2006 and April 2007. All patients underwent slit-lamp bio-microscopy, applanation tonometry and gonioscopy of the other eye to rule out angle closure. Small incision cataract surgery with intraocular lens implantation was performed in all affected eyes. Complete ophthalmic examination was done at each follow-up visit.Results:A total of 74 eyes with phacomorphic glaucoma were included in this study. The preoperative mean IOP was 38.4±14.3 mmHg and mean IOP at last follow-up was 12.7±2.4 mmHg. There was a statistically significant difference between IOP at presentation and IOP at last follow-up (P< 0.001). None of the eyes required long-term antiglaucoma medication. No significant intraoperative complications were noted. The final postoperative best corrected visual acuity was 20/40 or better in 51 patients. Eighteen eyes had corneal edema and 36 eyes had anterior chamber inflammation. Both conditions resolved with standard medical therapy.Conclusion:Manual small incision cataract surgery is safe and effective in controlling IOP and achieving good functional visual acuity with minimal complications in the management of phacomorphic glaucoma in developing countries.
