目的 采用Pentacam系统对2.2 mm、3.0 mm两种角膜缘切口白内障超声乳化吸除联合人工晶状体植入术后角膜前后表面高阶像差的变化以及两组间手术源性高阶像差值进行对比研究.方法 前瞻性对照临床研究.对2010年7～12月在温州医学院附属眼视光医院就诊的33例(55只眼)年龄相关性白内障患者分成2.2 mm切口组和3.0 mm切口组,行白内障超声乳化吸除联合折叠型人工晶状体植入术,分别于术前1d,术后3个月利用Pentacam系统测量并计算角膜前后表面的高阶像差(包括总的高阶像差、球差、彗差、三叶草、四叶草以及二次散光).使用独立样本t检验比较两组术前与术后角膜前后表面各高阶像差以及两组间角膜前后表面手术源性高阶像差.结果 两组白内障超声乳化吸除并人工晶状体植入术前、术后角膜前表面各指标高阶像差值差异均无统计学意义.3.0mm切口组角膜后表面总的高阶像差值术前1d为(0,186±0.036) μm,至术后3个月时明显增加为(0.217±0.04) μm,手术前后变化差异有统计学意义(P =0.046).2.2 mm切口组角膜后表面球差术前1d为(-0.128±0.036)μm,至术后3个月时增加为(-0.157±0.025)μm,手术前后变化差异有统计学意义(P =0.043).其余各项高阶像差指标手术前后的差异均无统计学意义.两组角膜前后表面手术源性高阶像差的差异均无统计学意义.结论 2.2 mm组及3.0 mm组白内障超声乳化吸除联合人工晶状体植入术后角膜前表面高阶像差及两组间手术源性高阶像差均无明显变化.3.0 mm切口组较2.2 mm切口组术后角膜后表面高阶像差改变差异有统计学意义,是否导致两组间术后视觉质量的差异还有待进一步研究.
目的 採用Pentacam繫統對2.2 mm、3.0 mm兩種角膜緣切口白內障超聲乳化吸除聯閤人工晶狀體植入術後角膜前後錶麵高階像差的變化以及兩組間手術源性高階像差值進行對比研究.方法 前瞻性對照臨床研究.對2010年7～12月在溫州醫學院附屬眼視光醫院就診的33例(55隻眼)年齡相關性白內障患者分成2.2 mm切口組和3.0 mm切口組,行白內障超聲乳化吸除聯閤摺疊型人工晶狀體植入術,分彆于術前1d,術後3箇月利用Pentacam繫統測量併計算角膜前後錶麵的高階像差(包括總的高階像差、毬差、彗差、三葉草、四葉草以及二次散光).使用獨立樣本t檢驗比較兩組術前與術後角膜前後錶麵各高階像差以及兩組間角膜前後錶麵手術源性高階像差.結果 兩組白內障超聲乳化吸除併人工晶狀體植入術前、術後角膜前錶麵各指標高階像差值差異均無統計學意義.3.0mm切口組角膜後錶麵總的高階像差值術前1d為(0,186±0.036) μm,至術後3箇月時明顯增加為(0.217±0.04) μm,手術前後變化差異有統計學意義(P =0.046).2.2 mm切口組角膜後錶麵毬差術前1d為(-0.128±0.036)μm,至術後3箇月時增加為(-0.157±0.025)μm,手術前後變化差異有統計學意義(P =0.043).其餘各項高階像差指標手術前後的差異均無統計學意義.兩組角膜前後錶麵手術源性高階像差的差異均無統計學意義.結論 2.2 mm組及3.0 mm組白內障超聲乳化吸除聯閤人工晶狀體植入術後角膜前錶麵高階像差及兩組間手術源性高階像差均無明顯變化.3.0 mm切口組較2.2 mm切口組術後角膜後錶麵高階像差改變差異有統計學意義,是否導緻兩組間術後視覺質量的差異還有待進一步研究.

Objective To study the effect of limbal incision with 2.2mm and 3.0mrn of phacoemulsification surgery on the optical high order aberrations (HOA) of the cornea measured with pentacam.Methods It was a prospective case series study.Fifty-five eyes of 33 patients were divided into 2.2mm group and 3.0mm group based on the size of limbal incision.HOAs of the anterior and posterior surface of comea were measured by pentacam before and after 3 months of phacoemulsification surgery.HOAs included the total high order aberration (tHOA),spherical aberration (SA),coma,trefoil,four-leaf clover and secondary astigmatism.Independent samples group t test were conducted to compare the difference of HOA between the two groups.Results The HOAs of the anterior surface was not statistically significant between 3.0mm group and 2.2mm group.The HOA of posterior surface increased from a mean of (0.186±0.036)μm preoperatively to (-0.128±0.036)μm postoperatively in 3.0 group.The increase was statistically difference (P =0.046).The HOA of posterior surface increased fiom a mean of (-0.128±0.036)μm preoperatively to (-0.157±0.025)μm postoperatively in 2.2 group.The increase was statistically difference (P =0.043).The changes of other HOAs and HOAs caused by surgery were no significant differences.Conclusions HOA of anterior surface,as well as caused by surgery are not significant different between 2.2mm group and 3.0mm group.There are significant differences in HOA of posterior surface between 2.2mm group and 3.0mm group.However,whether it is a factor to induce disparity of visual acuity needs to be further investigated.
