摘要

目的使用角膜地形图和调制传递函数(MTF)测量飞秒激光小切口基质透镜取出术(SMILE)矫治近视术后有效光学区(EOZ)的大小并分析其相关因素。

方法采用回顾性系列病例观察研究,选取2015年12月至2017年7月于济南明水眼科医院行SMILE手术的近视患者62例62眼。使用角膜地形图曲率差异图取值方法及MTF方法分别测量并计算SMILE术后6个月EOZ的大小。采用克隆巴赫系数和组内相关系数(ICC)评估测量数据的可重复性,采用Bland-Altman法进行一致性检验,采用Pearson相关分析法分析EOZ变化与其他参数之间的关系。

结果使用角膜切向曲率差异图测量的EOZ平均值的克隆巴赫系数和ICC均>0.9,重复性较好。2种方法测量的EOZ差值平均为(0.20±0.35)μm,具有较好的一致性,95%一致性界限为-0.49~0.89 μm。SMILE术后6个月,使用切向曲率差异图测得的EOZ为(5.32±0.25)mm,较预计光学区缩小了(1.18±0.25)mm;MTF法计算的EOZ为(5.07±0.32)mm,较角膜地形图获取的值小(0.20±0.35)mm,差异有统计学意义( t=-4.487, P<0.01)。角膜地形图EOZ与屈光度呈负相关( r=-0.364, P=0.004),与角膜曲率变化值及Q值变化量均呈显著正相关( r=0.367、0.514,均 P<0.01)。

结论使用角膜地形图切向曲率差异图测量的EOZ数据重复性好,与MTF法的计算值具有良好的一致性;SMILE术后EOZ显著缩小。

ABSTRACT

ObjectiveTo measure the effective optical zone (EOZ) after small incision lenticule extraction (SMILE) by using corneal topographic map and modulation transfer function (MTF), and to analyze the related factors affecting the EOZ.

MethodsA retrospective observational case series study was performed.Sixty-two myopic patients (62 eyes) who underwent SMILE between December 2015 and July 2017 in Jinan Mingshui Eye Hospital were enrolled.The EOZ was measured by using tangential corneal curvature topographic map and MTF pre- and 6-month post-operatively.The repeatability of data was determined by intraclass correlation coefficient (ICC) and Cronbach Alpha coefficients; the agreement of data was identified by using Bland-Altman plot; the correlations between EOZ and surgical parameters were analyzed by utilizing Pearson correlation coefficient.This study protocol was approved by the Ethics Committee of Jinan Mingshui Eye Hospital(No.2015[013]). Written informed consent was obtained from each patient before surgery.

ResultsThe ICC and Cronbach Alpha coefficients of EOZ measured by corneal topographic map were greater than 0.9, which showed high intraobserver repeatability.The Bland-Altman plots displayed relatively good agreement between the two methods.The 95% limits of agreement was -0.49 to 0.89 μm.Six months after SMILE, the EOZ measured by tangential corneal curvature gradient topographic map was (5.32±0.25)mm, which was (1.18±0.25)mm smaller than predicted optical zone, and the EOZ measured by MTF method was (5.07±0.32)mm, which was (0.20±0.35)mm smaller than corneal tomographic EOZ, and the difference was significant ( t=-4.487, P<0.01). A negative correlation was found between the EOZ and attempted refractive correction ( r=-0.364, P=0.004). The positive correlations were found between the EOZ and ΔKm or ΔQ 6 months after SMILE ( r=0.367, 0.514; both at P<0.01).

ConclusionsThe EOZ measured by tangential corneal curvature topographic map after SMILE is of high repeatability and is consistent with the result calculated by MTF method.The EOZ is significantly reduced after SMILE.

角膜屈光手术后视觉质量降低的主要原因包括较小的激光切削区及手术源性像差的引入 [ 1 ]。飞秒激光小切口基质透镜取出术(small incision lenticule extraction,SMILE)的临床开展使角膜屈光手术走向了微创时代,使手术风险降低的同时,患者术后视觉质量也得到进一步提升,但是仍有极少部分患者未达到术后预期效果,出现夜间视力下降、光晕、眩光等症状 [ 2 , 3 , 4 ]。光学区作为激光切削前后提供功能性视觉的角膜表面区域,其大小直接影响着术后的视觉效果 [ 5 , 6 ]。如何获得较好的有效光学区(effective optical zone,EOZ)是手术质量提升的关键因素。以往通常使用角膜地形图或光线追迹原理的方法对传统准分子激光角膜原位磨镶术(laser in situ keratomileusis,LASIK)或表层手术后EOZ进行定义,但不同方法使用的设备、采集的阈值以及使用的参照点不同 [ 7 , 8 , 9 , 10 , 11 , 12 , 13 ],因此无法进行比较。目前尚缺乏使用不同方法测量SMILE术后EOZ的研究。本研究分别使用角膜地形图和调制传递函数(modulation transfer function,MTF)对SMILE术后EOZ进行测量,以探讨其变化特征并对2种方法进行比较。
