Viscoless Manual Small Incision Cataract Surgery with Trabeculectomy.

Abstract：

PURPOSE:To compare the efficacy of combined manual small incision cataract and glaucoma surgery with anterior chamber maintainer (ACM) alone versus that with intraoperative viscoelastics. METHODS:Hospital electronic medical records of patients who underwent small incision cataract and trabeculectomy and intraocular lens implantation without Mitomycin-C from 2014 to 2016 were identified from the hospital operation theater database for this retrospective, hospital-based comparative study. All MSICS surgeries were performed by a single surgeon under peribulbar block. Data retrieved from all patients undergoing surgery with viscoelastic (group 2) or under AC maintainer without viscoelastic (group 1) included preoperative visual acuity, preoperative treated intraocular pressure, number of anti-glaucoma medications before surgery, total surgical time, intraoperative complications, postoperative best-corrected visual acuity and IOP at one week and one month, need for additional procedures, and corneal clarity. Differences in surgical time and postoperative course in both groups were compared. RESULTS:Of 268 manual combined cataract and glaucoma surgeries done from 2014-2016, we identified 147 eyes of 130 age-matched patients, which included 51 PACG, 50 POAG, 12 NTG, and 24 PXG eyes with a mean age of 66 ±11.2 years and 64± 10.8 years in group 2 (n=74) and group 1 (n=73), respectively; p=0.9. The surgical time was significantly lower in group 1 (16±4.8 minutes compared to 44±14.6 minutes for group 2; p<0.001) with transient edema seen <1 week after surgery in 24 eyes of group 2 and seven eyes of group 1; p=0.02. The postoperative IOP at all postoperative visits dropped to >50% in both groups with 11 eyes (PXG n=6, PACG n=5) requiring medications for rise in intraocular pressure at a median time of 1.2 months (r=0.2-3 months). The final visual acuity improved >4 snellen lines in all cases with two patients with advanced damage having 1 line improvement in Snellen acuity at final follow-up. CONCLUSION:The ACM can help completely avoid the use of viscoelastic during surgery, which can be an effective technique for MSICS with trabeculectomy in low resource stings. Training for such procedures should be incorporated into residency training programs.
