The Surgical outcomes of combined Phacoemulsification, Posterior Chamber Lens Implantation and Trabeculectomy in Glaucoma Patients

ABSTRACT

PURPOSE: To access the surgical outcomes of combined cataract surgery and trabeculectomy in glaucoma patients. METHODS: Twenty one patients (23 eyes) with preoperative visual acuity over 0.3 treated by combined surgery in severance hospital from 1997 to 1999 were included in this study. We examined preoperative and postoperative visual acuity, intraocular pressure, number of ocular hypotensive eyedrops, visual field test retrospectively. RESULTS: A total of 21 patients (23 eyes) were observed. Mean preoperative intraocular pressure (IOP) were 18.62+/-2.58 mmHg and that of postoperative 1-year follow-up period were decreased to 15.43+/-2.04 mmHg (p<0.05). One, 2 and 3 years after surgery, 2 eyes (8%), 3 eyes (13%), 5 eyes (20%) were aggravated by Advanced Glauma Intervention Study (AGIS) scoring system, respectively. Although there was significant decrease in postoperative intraocular pressure (p<0.05), no significant change was observed in postoperative IOP, mean deviation (MD), and corrected pattern standard deviation (CPSD) between aggravated group and non aggravated group. CONCLUSIONS: The IOP was maintained under 21 mmHg following combined cataract surgery and trabeculectomy and AGIS score of some patients was aggravated during the follow up period. There were no significant difference in postoperative IOP, MD and CPSD between aggravated and non aggravated group, but rim volume and rim area decreased significantly in aggravated group at postoperative two years.
