PURPOSE
To evaluate and compare the clinical results of implantation of foldable silicone(SI40NB, PhacoFlexIITM, AMO) intraocular lenses(IOLs) and acrylic(MA60BM, AcrySofTM, Alcon) IOLs. METHODS: Seventy eyes of 35 healthy senile cataract patients who had uneventfully implanted silicone IOL in one eye and acrylic IOL in the other eye were observed on their best corrected visual acuities(BCVA) and postoperative complications such as posterior capsule opacification(PCO) with its incidence and site. RESULTS: Mean postoperative follow-up period was 17.6month +/-2.08(S.D.)(range 13 to 20 months). Postoperative BCVA, with the measurement of above 0.8 was 29% in SI40NB-IOL implanted group(S group) and 37% in MA60BM-IOL implanted group(M group), above 0.5 was 88.4% in S group and 100% in M group. PCO was 19 eyes(54.3%) in S group and 5 eyes(14%) in M group. Anterior capsular contracture was 3 eyes(8.6%) in S group and 1 eye(2.9%) in M group. Two eyes(5.7%) of capsular capture and 3 eyes(8.6%) of decentration(1<1.5 mm) were only in S group. Eight eyes(22.9%) of microvacuole were only in M group. A eye of S group with severe PCO had taken Nd:YAG posterior capsulotomy. To evaluate the PCO character, posterior capsule was imaginary divided into central part and peripheral part at IOL's optic edge. In M group, among 5 eyes(14.3%) of peripheral part opacification, a eye(2.9%) was progressed into central part. In S group, among 19 eyes(54.3%) of peripheral part opacification, 11 eyes(31.4%) were progressed into central part. There was 20% central progression rate in M group and 57.9% in S group. CONCLUSIONS: MA60BM-IOL showed good visual outcome and fewer postoperative complication than SI40NB-IOL, especially in central PCO which is closely related visual outcome. |
