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