目的 比较飞秒激光制瓣LASIK(飞秒LASIK)和有晶状体眼后房型人工晶状体(ICL)植入在矫正高度近视术后光学质量和客观眼内散射的差异.方法 前瞻性病例对照研究.入选近视度数为-6～-12 D患者44例,年龄18 ～40岁,其中24例(48眼)接受飞秒LASIK术,20例(40眼)行ICL植入术,除角膜厚度(t=4.77,P＜0.05)外,2组间术前资料差异均无统计学意义.术后1个月和3个月运用视觉质量分析系统(OQASTMⅡ)分别测量客观散射指数、调制传递函数截止频率、斯特列尔比和对比度为100％、20％及9％的OQAS值.术后随访3个月,组内比较采用配对t检验,2组间比较采用独立样本t检验.结果 术后1个月ICL组相较飞秒LASIK组残余轻度散光(t=4.95,P＜0.05);2组间裸眼及矫正视力、等效球镜度差异均无统计学意义,安全性指数ICL组大于飞秒LASIK组(t=2.22,P＜0.05).术后3个月同术后1个月相比,ICL组等效球镜度数变化差异无统计学意义,而飞秒LASIK组有50％眼发生平均约(-0.72±1.23)D的屈光回退.术后1个月和3个月2组间各光学质量参数比较差异均无统计学意义,仅在术后1个月ICL组的客观散射指数大于飞秒LASIK组(t=-2.14,P＜0.05).结论 飞秒LASIK或ICL植入均能有效矫正-6 D到-12 D范围的高度近视,同飞秒LASIK相比,植入ICL更安全更稳定;尽管植入ICL早期客观眼内散射略大,但两者术后总体光学质量结果相似.
目的 比較飛秒激光製瓣LASIK(飛秒LASIK)和有晶狀體眼後房型人工晶狀體(ICL)植入在矯正高度近視術後光學質量和客觀眼內散射的差異.方法 前瞻性病例對照研究.入選近視度數為-6～-12 D患者44例,年齡18 ～40歲,其中24例(48眼)接受飛秒LASIK術,20例(40眼)行ICL植入術,除角膜厚度(t=4.77,P＜0.05)外,2組間術前資料差異均無統計學意義.術後1箇月和3箇月運用視覺質量分析繫統(OQASTMⅡ)分彆測量客觀散射指數、調製傳遞函數截止頻率、斯特列爾比和對比度為100％、20％及9％的OQAS值.術後隨訪3箇月,組內比較採用配對t檢驗,2組間比較採用獨立樣本t檢驗.結果 術後1箇月ICL組相較飛秒LASIK組殘餘輕度散光(t=4.95,P＜0.05);2組間裸眼及矯正視力、等效毬鏡度差異均無統計學意義,安全性指數ICL組大于飛秒LASIK組(t=2.22,P＜0.05).術後3箇月同術後1箇月相比,ICL組等效毬鏡度數變化差異無統計學意義,而飛秒LASIK組有50％眼髮生平均約(-0.72±1.23)D的屈光迴退.術後1箇月和3箇月2組間各光學質量參數比較差異均無統計學意義,僅在術後1箇月ICL組的客觀散射指數大于飛秒LASIK組(t=-2.14,P＜0.05).結論 飛秒LASIK或ICL植入均能有效矯正-6 D到-12 D範圍的高度近視,同飛秒LASIK相比,植入ICL更安全更穩定;儘管植入ICL早期客觀眼內散射略大,但兩者術後總體光學質量結果相似.

Objective To compare optical quality and objective intraocular scattering after femtosecond laser in situ keratomileusis FS-LASIK) and implantable collamer lenses (ICL)implantation for high myopia.Methods This observational case-control study selected 44 consecutive patients (ages range from 18 to 40 years) with myopia between-6 D to-12 D,of which 24 cases (48 eyes) accepted FS-LASIK surgery and 20 cases (40 eyes) underwent ICL implantation.In addition to the corneal thickness (t=4.77,P＜0.05),all the preoperative data were matched between the two groups.Measurements were performed one and three-month postoperatively by a double-pass optical quality analysis system (OQASTM,Visiometrics,Spain).We assessed the objective scattering index (OSI),modulation transfer function (MTF) cutoff frequency,Strehl ratio and OQAS values (OVs) at contrasts of 100％,20％ and 9％.Paired t test for data comparison within group and independent sample t test between groups were used for statistical analysis in postoperative 3 months follow-up.Results After 1 month,except for residual mild astigmatism (t=4.95,P＜0.05) and more safety index (t=2.22,P＜0.05) in ICL group,no significant differences were found between the groups in UCVA,BSCVA and equivalent sphere refraction.After 3 months,while no significant change of equivalent sphere refraction in ICL group compared with 1 month,50％ eyes in FS-LASIK group had an average refractive regression of-0.72±0.72 D.We also found no significant differences in the MTF cutoff frequency,Strehl ratio,100％OVs,20％OVs,and 9％OVs between groups after 1 and 3 months,only OSI of ICL surgery after 1 month was greater than FS-LASIK group (t=2.14,P＜0.05).Conclusion Either FS-LASIK or ICL implantation could effectively correct high myopia range from -6 D to-12 D; However,ICL implantation was safer and more stable when compared with FS-LASIK surgery.Although early objective intraocular scattering after ICL implanted was slightly higher,the overall results of postoperative optical quality were similar.
