CATARACT SURGERIES BY PHACO-SANDWICH TECHNIQUE THROUGH SCLEROCORNEAL TUNNEL, A COHORT STUDY IN OMAN
Abstract
Background: To evaluate the changes in Preoperative and Postoperative keratometry results andrapid visual rehabilitation in Cataract surgery by our phaco-sandwich technique through the self
sealing sclero-corneal tunnel incision without phacoemulsification. Methods: 96 eyes of 88
patients with age-related cataracts underwent small incision suture less cataract surgery without
phacoemulsification. All eyes were operated by the phaco-sandwich technique through
sclerocorneal tunnel with 6 mm frown-shaped external scleral incision. 6 mm single piece PMMA
lens was implanted in the capsular bag. Patients were evaluated at 1week, 4 weeks and 12 weeks
post-operatively. Results: Ninety six eyes of eighty eight patients were our cohort. During the first
post-operative week 8 eyes (8.3%) had uncorrected visual acuity (UCVA) of 6/6. By the end of 12
post-operative weeks, 33 eyes(34.5%) had UCVA of 6/6. 64 (66.7%), 72(75%) and 80(83.3%)
eyes had best correctable visual acuity (BCVA) of 6/6 after 4 weeks, 8 weeks and 12 weeks
respectively. 64 (66.7%) eyes after 4 weeks, 72 (75%) after 8 weeks and 80 (83%) after 12 weeks
had best correctable visual acuity (BCVA) of 6/6. Conclusion: Suture less, small-incision cataract
surgery is an economical, safe and effective method of managing cataract cases. This technique
also ensures satisfactory and rapid rehabilitation for patients. This procedure can be effectively
applied to clear the backlog of cataract-related blindness in places wherein the resources for phaco
facilities are not available.
