新型前房型人工晶状体一期二期植入临床观察

目的：评价新型弹性开放襻前房型人工晶状体一期或二期植入的临床效果。方法：共34只眼，一期前房型人工晶状体植入19只眼，其中老年性白内障12只眼，外伤性昌状体半脱位4只眼，外伤性白内障3只眼；二期植入15只眼，其中老年性白内障术后8只眼，外伤性白内障术后7只眼。术后随访半年以上。结果：一期植入术后68.4%(13只）眼视力≥0.5，其中≥1.0有3只眼，占15.8%，二期植术术后73.3%(11只眼）视力≥0.5，其中≥1.0有4只眼，占26.7%；术后常见并发症为角膜水肿的眼压升高。结论：新型弹性开放襻前房型人工晶状体一期二期植入均安全、有效。

New type anterior chamber intraocular lenses in primary and secondaryimplantation

ObjectiveTo evaluate the efficacy of new flexible open-loop anterior chamber intraocular lenses in primary and secondary implantation.MethodsPrimary anterior chamber intraocular lenses implantation in 19 eyes(12 with senile cataract,4 with traumatic lens subluxation and 3 with traumatic cataract)and secondary anterior chamber intraocular lenses implantation in 15 eyes(8 after senile cataract surgery and 7 after traumatic cataract surgery).All patients were followed up for at least 6 months.ResultsIn the primary implantation of 19 eyes,13 eyes(68.4%)had a final visual acuity of 0.5 or better and 3 eyes(15.8%)had 1.0 or better;and in the secondary implantation of 15 eyes,11 eyes(73.3%)had 0.5 or better and 4 eyes (26.7%)had 1.0 or better.The postoperative complications were corneal edema and intraocular pressure increase.Conclusion New flexible open-loop anterior chamber intraocular lenses is safe and effective for both primary and secondary implantation.
