角膜缘隧道切口白内障超声乳化折叠式人工晶体植入术

Phacoemulsification and foldable IOL implantation with limbal tunnel incision

目的 :评价角膜缘隧道切口的白内障超声乳化折叠式人工晶体植入术的效果。 方法 :对 6 6例 (72眼 )老年性、并发性、外伤性白内障采用 3.2 mm角膜缘隧道切口 ,行白内障超声乳化并植入折叠式人工晶体 ,观察手术前后视力、角膜曲率、角膜地形图的变化。 结果 :术后 1天、1周、1个月的视力达 0 .5以上者分别占 6 9.4%、80 .6 %和86 .1% ,术后 1周平均散光为 (1.85± 0 .89) D,比术前增加 0 .30 D(P<0 .0 1) ,角膜地形图显示切口处轻度陡峭或平坦 ,术后 1个月平均散光为 (1.48± 1.0 2 ) D,P>0 .0 5 ,角膜地形图显示已恢复术前状态。 结论 :角膜缘隧道切口的白内障超声乳化折叠式人工晶体植入术能简化手术步骤 ,术后视力恢复快 ,炎症反应轻 。

Objectives: To evaluate the efficacy of phacoemulsification and foldable IOL implantation with limbal tunnel incision Methods: A 3.2mm limbal tunnel incision was made on 72 eyes of 66 patients with senile, complicated and traumatic cataract Phacoemulsification and foldable IOL implantation was performed Visual acuity, corneal curvature and corneal topography were measured after the surgery Results: One day, one week and one month after the surgery, visual acuity exceeded 0.5 in 69 4%, 80 6%,86 1% of the patients respectively. One week after the surgery, the mean astigmatism was (1 85±0 89)D( P <0 01), 0 30 D more than that before the surgery Corneal topography showed that the incision was steep or flat One month after the surgery, the mean astigmatism was (1 48±1 02)D, P >0 05,corneal topography had recovered Conclusions: Phacoemulsification and foldable IOL implantation with limbal tunnel incision have comparatively simple, with less postoperative inflammation and faster recovery of visual acuity
