目的 对比分析前弹力层下角膜磨镶术(sub-bowman's keratomileusis,SBK)术中应用负压吸引椭圆环与圆环的临床效果.方法 采用自身对照法观察134例(268只眼)接受SBK的近视患者,术中随机决定双眼中的一眼使用负压吸引椭圆环制作角膜瓣为实验组,对侧眼则常规使用圆环制作角膜瓣为对照组,术后1d、3d、1周、2周、3周,1个月、3个月复查,观察记录包括裸眼视力、屈光度、术中术后并发症等情况,并进行统计学处理.结果 术中角膜瓣缘出血试验组的发生率为6.0％(8只眼),对照组为17.2％(23只眼),两组比较差异有统计学意义(x2=7.1496,P=0.0075)；瓣缘鲸尾征试验组的发生率为4.48％(6只眼),对照组为14.2％(19只眼),两组比较差异有统计学意义(x2=6.3526,P=0.0117).两组术后裸眼视力、残留屈光度差异无统计学意义(P＞0.05).术中术后均无严重并发症.结论 SBK术中应用负压吸引椭圆环治疗近视安全有效并且有效降低了角膜瓣缘出血和鲸尾征的发生率.
目的 對比分析前彈力層下角膜磨鑲術(sub-bowman's keratomileusis,SBK)術中應用負壓吸引橢圓環與圓環的臨床效果.方法 採用自身對照法觀察134例(268隻眼)接受SBK的近視患者,術中隨機決定雙眼中的一眼使用負壓吸引橢圓環製作角膜瓣為實驗組,對側眼則常規使用圓環製作角膜瓣為對照組,術後1d、3d、1週、2週、3週,1箇月、3箇月複查,觀察記錄包括裸眼視力、屈光度、術中術後併髮癥等情況,併進行統計學處理.結果 術中角膜瓣緣齣血試驗組的髮生率為6.0％(8隻眼),對照組為17.2％(23隻眼),兩組比較差異有統計學意義(x2=7.1496,P=0.0075)；瓣緣鯨尾徵試驗組的髮生率為4.48％(6隻眼),對照組為14.2％(19隻眼),兩組比較差異有統計學意義(x2=6.3526,P=0.0117).兩組術後裸眼視力、殘留屈光度差異無統計學意義(P＞0.05).術中術後均無嚴重併髮癥.結論 SBK術中應用負壓吸引橢圓環治療近視安全有效併且有效降低瞭角膜瓣緣齣血和鯨尾徵的髮生率.

Objective To compare effectiveness of Sub-Bowman's Keratomileusis (SBK)with oval suction ring in oval and circular suction ring.Methods One hundred thirty-four patients (268 eyes)were observed by methods of self-contrast(L vs R).One eye of each patient was randomly chosen as test group in SBK with oval suction ring,and the other eye was self-contrast group with circular suction ring.Postoperative 1 day,3 days,1 week,2 weeks,3 weeks,1 month,3 months review,observation records,including uncorrected visual acuity,manifest refraction,intraoperative and postoperative complications.The data were analyzed statistically.Results Intraoperative hemorrhage of the corneal flap margin in the test group was 6.0％ and 17.2％ in the control group,which was statistically significant(x2=7.1496,P =0.0075);whale tail sign in the test group was 4.48％ and 14.2％ in the control group,which was statistically significant(x2=6.3526,P =0.0117).There were no significant differences between eyes in uncorrect visual acuity,manifest refraction during the follow time(P ＞0.05).There were no severe complications of intraoperative and postoperative.Conclusions SBK with oval suction ring is a safe and efficient method to correct myopia and reduce the corneal flap margin of the incidence of hemorrhage and the whale tail sign.
