白内障手术不同切口对人眼波前像差的影响

Effect of higher-order aberrations on different incision of cataract surgery

目的:探讨白内障超声乳化行透明角膜切口和巩膜反眉型隧道切口对术后人工晶状体眼高阶像差的影响。方法:实验组为行白内障超乳化透明角膜切口组(46眼Ⅰ组),白内障超声乳化巩膜反眉型隧道切口组(48眼Ⅱ组),并设同龄正常人为对照组(52眼)。分析指标为术后7d,3mo总高阶像差值。结果:术后7d对照组,Ⅰ,Ⅱ组总高阶像差值两两比较均有显著性差异(P<0.01)。术后3moⅠ,Ⅱ组总高阶像差值无显著性差异(P>0.05),与同年龄正常人比较有显著性差异(P<0.01)。结论:人工晶状体眼的高阶像差较同龄正常人增加。白内障超声乳化透明角膜切口对术后人工晶状体眼高阶像差的早期影响大于巩膜反眉型隧道切口,随时间推移二者趋于一致。

AIM： To evaluate the effect of pseudophakic higherorder aberrations after cataract phacoemulsification surgery between transparent cornea incision and scleral tunnel incision. METHODS： Age-related cataract phacoemulsification surgery intraocular lens implantation were diva into 2 groups： transparent cornea incision group （46 eyes）, scleral tunnel incision group（48 eyes）, the normal patient of the same age were control group （52 eyes）, total higher-order aberrations evalue were measured and analysised at 7 days, 3 months. RESULTS： There was significant difference （P〈 0.01 ） of total higher-order aberrations evalue at 7 days between every group,there was no significant difference （P〉 0.05） of total higher-order aberrations evalue between transparent cornea incision group and scleral tunnel incision group at 3 months. There was significant difference （ P 〈 0.01 ） of total higher-order aberrations evalue at 3 months between transparent cornea incision group or scleral tunnel incision group and control group. CONCLUSION： Pseudophakic had more higher total higher-order aberrations evalue than normal eyes. Transparent cornea incisions have a greater impact of higher-order aberrations at early stage after phacoemulsification compared with scleral tunnel incision, with the passage of time.
