目的：比较透明角膜切口及巩膜隧道切口白内障超声乳化术对患者角膜散光的影响。<br> 方法：单纯白内障患者88例122眼,按切开入路不同随机分为两组：透明角膜组( A组)40例60眼；巩膜隧道组( B组)48例62眼。观察术前、术后1d；1wk；1mo时平均角膜散光度、手术源性散光( surgically induced astigmatism, SIA)、裸眼视力及最佳矫正视力的情况,并进行统计学分析。<br> 结果：术后1d；1wk；1mo,两组平均角膜散光度的比较差异均有统计学意义(P<0.05)；术后1d；1wk,SIA值差异有统计学意义(P<0.05),术后1mo,两组SIA值的比较差异无统计学意义(P>0.05)；术后1d；1wk,裸眼视力≥0.5及最佳矫正视力≥0.8比较差异均有统计学意义(P<0.05),术后1mo,两组之间比较差异无统计学意义(P>0.05)。<br> 结论：巩膜隧道切口白内障超声乳化摘除联合人工晶体植入术对角膜散光改变较小,根据角膜地形图指导个性化切口位置,对自身角膜散光的处理更有优势。
目的：比較透明角膜切口及鞏膜隧道切口白內障超聲乳化術對患者角膜散光的影響。<br> 方法：單純白內障患者88例122眼,按切開入路不同隨機分為兩組：透明角膜組( A組)40例60眼；鞏膜隧道組( B組)48例62眼。觀察術前、術後1d；1wk；1mo時平均角膜散光度、手術源性散光( surgically induced astigmatism, SIA)、裸眼視力及最佳矯正視力的情況,併進行統計學分析。<br> 結果：術後1d；1wk；1mo,兩組平均角膜散光度的比較差異均有統計學意義(P<0.05)；術後1d；1wk,SIA值差異有統計學意義(P<0.05),術後1mo,兩組SIA值的比較差異無統計學意義(P>0.05)；術後1d；1wk,裸眼視力≥0.5及最佳矯正視力≥0.8比較差異均有統計學意義(P<0.05),術後1mo,兩組之間比較差異無統計學意義(P>0.05)。<br> 結論：鞏膜隧道切口白內障超聲乳化摘除聯閤人工晶體植入術對角膜散光改變較小,根據角膜地形圖指導箇性化切口位置,對自身角膜散光的處理更有優勢。

AlM:To compare the effect of different incision in corneal astigmatism after phacoemulsification. <br> METHODS: Totally 88 cases ( 122 eyes ) with pure cataract were randomly divided into two groups. Forty cases (60 eyes) were clarity corneal incision in group A, and 48 cases ( 62 eyes ) were sclera tunnel incision in group B. Mean corneal astigmatism, surgically induced astigmatism ( SlA ) , uncorrected visual acuity ( UCVA ) and best correct vision acuity ( BCVA ) were observed in pre- and post-operation at 1d;1wk;1mo. <br> RESULTS: The mean astigmatism had statistically significant difference between two groups at 1d; 1wk;1mo after operation(P<0. 05). The SlA had statistically significant difference at 1d ( P<0. 05 ); The SlA had no statistically significant difference between two groups at 1mo after operation (P>0. 05). UCVA≥0. 5 and BCVA≥0. 8 had statistically significant difference at 1d; 1wk ( P<0. 05) . There had no statistically significant difference at 1mo after operation (P>0. 05). <br> CONCLUSlON: Phacoemulsification with scleral tunnel incision remove combined intraocular lens ( lOL ) implantation has small changes to corneal astigmatism. By selecting personalized corneal incision according to the corneal topography might be more beneficial.
