3.8mm小切口碎核水凝胶人工晶体植入术的临床研究

Clinical study on foldable intraocular lens implatation for cataract patients with small incision

目的 :探讨 3.8mm小切口碎核同期植入折叠式水凝胶人工晶体手术的效果。方法 :对53例 (56只眼 )白内障碎核折叠式水凝胶人工晶体植入患者的术后视力、屈光状态、角膜状态、前房反应进行总结。结果 :术后 1周、1个月、3个月 ,裸眼视力≥ 0 .5的眼数分别为 :4 9只眼 (87.5% )、52只眼(92 .9% )、52只眼 (92 .9% ) ;平均散光度分别为 :(1.0 2± 0 .71) D、(0 .93± 0 .59) D、(0 .85± 0 .6 7) D。平均散光度与术前比较 ,差异无显著性 (P>0 .0 5)。术后角膜透明 ,前房反应轻。结论 :手术切口小 ,操作简便。术后反应轻、散光小 ,患者短时间内可以获得最佳视力 。

Objective:[WT5BZ]The results of muchotomy which was performed through a 3.8mm scleral tunnel incision and foldable intraocular lens implantation were analyzed [WT5HZ]Methods:[WT5BZ]On 56 eyes with cataract of 53 cases,nuchotomy with foldable IOL (hydrogel intraocular lens) implantation was performed.The results of postoperative vision refraction,corneal edema,anterior chamber flare were retrospectively summarized.[WT5HZ]Results: [WT5BZ]uncorrected visual acuitis of postoperative,1 week,1 month and 3 months,≥0.5 were in 49 eyes (87.5%),52 eyes (92.9%),52 eyes (92.9%);respectively.The mean dicpters of astigmatism at postoperative 1 week,1 month and 3 months were (1.02±0.71)D,(0.93±0.59)D,(0.85±0.67)D,respectively.The mean dicpters of astigmatism at postoperative 1 week,1 month and 3 months compared with that before the surgery had no significant difference (P>0.05).The postoperative corneal transparent and anterior chamber flare were mild.[WT5HZ]Conclusion:[WT5BZ]The surgical incision is small and easy to perform.postoperatively,the reaction in mild ,the change of astigmatism is small in degree,the best visual acuity can be obtained at the early stage and the refractive status is stable ,thus the eduration for restoration is greatly shortened.
