PATIENTS AND METHODS: Fifty eyes of 47 patients who underwent scleral -fixated IOL implantation were retrospectively evaluated. Twenty-one (42%) ey es had a history of trauma and 29 (58%) eyes had previously undergone cataract surgery. In all cases, IOL implantation by 4-point scleral fixation was perform ed and the knots of fixation sutures were rotated and buried in the globe. The I OL position was adjusted by suture rotation for best centration. RESULTS: The me an follow-up time was 7 ±4 months. Four (8%) eyes had minimal corneal edema p reoperatively. Cystoid macular edema was noted in 2 (6.8%) eyes in the cataract surgery group and 8 (38%) eyes in the posttraumatic group. Two (9.5%) eyes in the posttraumatic group had atrophic macular changes and 1 (4.7%) had corneal scarring,which impaired vision. No complications such as knot exposure, tilting of the IOL, decentralization, or endophthalmitis were noted postoperatively. Pos toperative mean corrected visual acuity was 0.4 ±0.3 in the posttraumatic group and 0.4 ±0.2 in the cataract surgery group. CONCLUSION: The 4-point scleral f ixation technique resulted in no serious postoperative complications such as sut ure exposure and endophthalmitis. Because the knot can be rotated and buried in the globe, knot exposure is less likely to occur. This procedure ismore effectiv e than other techniques regarding IOL centralization.展开更多
