目的 探讨虹膜定位联合波前像差引导LASEK施行个体化切削手术治疗近视的临床疗效.方法 接受此种患者39例(78只眼)作为试验组,同期行常规LASEK手术患者41例(82只眼)作为对照组,对两组的术后6个月疗效进行比较.结果 术后6个月两组所有患者术后裸眼视力≥术前最佳矫正视力(BCVA),试验组和对照组术后视力较术前BCVA提高≥1行分别为29只眼(37.18%)和16只眼(19.51%),试验组明显优于对照组(P＜0.01).试验组术后6个月等效球镜≤±0.5D试验组31只眼(39.74%),对照组17只眼(20.73%),试验组明显小于对照组(P＜0.01).术后6个月采用与术前瞳孔直径基本一致时测量数据,试验组和对照组总高阶像差的RMS值分别为0.537±0.31和0.715±0.43,试验组RMS值小于对照组(P＜0.05).两组RMS值较术前均有不同程度增加,增高幅度分别为21.60%和38.88%,试验组明显小于对照组(P＜0.01).术后6个月随访时角膜haze发生率两组比较差异无统计学意义(P＞0.05),且两组均无2级以上haze.试验组和对照组患者对术后视觉质量表示"满意"或"基本满意"分别占76只眼(97.44%)和74只眼(90.24%),试验组术后满意度优于对照组(P＜0.05).结论 虹膜定位联合波前像差引导LASEK安全、有效,术后视力提高理想,残余屈光度较少、高阶像差增幅减小及满意度较高.
目的 探討虹膜定位聯閤波前像差引導LASEK施行箇體化切削手術治療近視的臨床療效.方法 接受此種患者39例(78隻眼)作為試驗組,同期行常規LASEK手術患者41例(82隻眼)作為對照組,對兩組的術後6箇月療效進行比較.結果 術後6箇月兩組所有患者術後裸眼視力≥術前最佳矯正視力(BCVA),試驗組和對照組術後視力較術前BCVA提高≥1行分彆為29隻眼(37.18%)和16隻眼(19.51%),試驗組明顯優于對照組(P＜0.01).試驗組術後6箇月等效毬鏡≤±0.5D試驗組31隻眼(39.74%),對照組17隻眼(20.73%),試驗組明顯小于對照組(P＜0.01).術後6箇月採用與術前瞳孔直徑基本一緻時測量數據,試驗組和對照組總高階像差的RMS值分彆為0.537±0.31和0.715±0.43,試驗組RMS值小于對照組(P＜0.05).兩組RMS值較術前均有不同程度增加,增高幅度分彆為21.60%和38.88%,試驗組明顯小于對照組(P＜0.01).術後6箇月隨訪時角膜haze髮生率兩組比較差異無統計學意義(P＞0.05),且兩組均無2級以上haze.試驗組和對照組患者對術後視覺質量錶示"滿意"或"基本滿意"分彆佔76隻眼(97.44%)和74隻眼(90.24%),試驗組術後滿意度優于對照組(P＜0.05).結論 虹膜定位聯閤波前像差引導LASEK安全、有效,術後視力提高理想,殘餘屈光度較少、高階像差增幅減小及滿意度較高.

Objective To evaluate the clinical effects with iris location combined wave-fiont guided laser-assised subepithelial keratomileusis(LASEK)in the treatment of myopia.Methods Iris location combined wave-front aberration guided LASEK was performed in 39 patients(78 eyes)as experimental group,and traditional LASEK was performed in 41 patients(82 eyes)as control group.The therapeutic effects were compared between two groups.Results At 6 months postoperatively,the naked vision of all patients in two groups surpassed the preoperative best corrected visual acuity of each group.The poswperative naked vision of 29 eyes(37.18%)in experimental group and 16 eyes(19.51%)in control group were higher at least one line than the preoperative best corrected visual acuity.The experimental group was obviously better than control group(P ＜0.01).The remainder astigmatism postoperatively of 31 eyes(39.74%)in experimental group and 17 eyes(20.73%)in control group were within ± 0.5D.The experimental group was obviously better than control group(P＜0.01).The root mean square of higher order aberration value were(0.537± 0.31)μ m in experimental group and(0.715± 0.43)μ m in control group.The root mean square of higher order aberration value in experimental group was less than that in control group at 6 months postoperatively(P ＜0.05).Total higher order aberration value of experimental group added 21.60% and control group added 38.88%.The increase of total higher order aberration in experimental group was less than that in control group(P ＜0.01).There were 76 eyes (97.44%)in experimental group and 74 eyes(90.24%)in control group feeling comfortable with visual quality at 6 months postoperatively(P ＜0.05).Conclusion Good therapeutic effects can be achieved in iris location combined wave-front aberration guided LASEK in the treatment of myopia.
