Abstract

BACKGROUND

The purpose of this retrospective study was to evaluate cylinder axis agreement between manifest refraction (MR), cycloplegic refraction (CR), Allegro Oculyzer ІІ and Allegro Topolyzer-Vario.

METHODS

We included 82 patients (32 males and 50 females, 28.1 ± 8.7 years old), with 156 eyes scheduled for wavefront optimized laser refractive surgery, photorefractive keratectomy (PRK) in 50 eyes and laser-assisted in situ keratomileusis (LASIK) in 106 eyes, for correction of simple, myopic, hyperopic or mixed astigmatism. Cylinder axis was determined under manifest and cycloplegic refractions and using Allegro Occulyzer ІІ and Allegro Topolyzer-Vario platforms. Cylinder axis agreement was assessed by intraclass correlation coefficient, Pearson correlation coefficient and by the method described by Bland and Altman.

RESULTS

Intraclass correlation coefficient and Pearson correlation coefficient showed statistically significant cylinder axis agreement between manifest refraction, cycloplegic refraction, Allegro Oculyzer ІІ and Allegro Topolyzer-Vario (p <0.001). Despite statistically significant cylinder axis agreement between the four measuring tools, 4 of 156 eyes (2.5%) showed unexpected discrepancy between Allegro Oculyzer ІІ and Allegro Topolyzer-Vario cylinder axis.

CONCLUSION

Although cylinder axis shows statistically significant agreement between manifest refraction, cycloplegic refraction, Allegro Oculyzer ІІ and Allegro Topolyzer-Vario, unexpected discrepancies occur.

摘要

背景

本回顾性研究的目的是评估显然验光（MR）、睫状肌麻痹验光（CR）、Allegro Oculyzer II和Allegro Topolyzer-Vario之间的柱镜轴位一致性。

方法

我们纳入了82例患者（男性32例，女性50例，年龄28.1±8.7岁），其156只眼计划行波前优化激光屈光手术，其中50只眼行准分子原位角膜磨镶术（PRK），106只眼行准分子激光原位角膜磨镶术（LASIK），以矫正单纯性、近视性、远视性或混合性散光。在显然验光和睫状肌麻痹验光下以及使用Allegro Oculyzer II和Allegro Topolyzer-Vario平台测定柱镜轴位。通过组内相关系数、Pearson相关系数以及Bland和Altman描述的方法评估柱镜轴位一致性。

结果

组内相关系数和Pearson相关系数显示，显然验光、睫状肌麻痹验光、Allegro Oculyzer II和Allegro Topolyzer-Vario之间的柱镜轴位一致性具有统计学意义（p<0.001）。尽管四种测量工具之间的柱镜轴位一致性具有统计学意义，但156只眼中有4只眼（2.5%）在Allegro Oculyzer II和Allegro Topolyzer-Vario柱镜轴位之间显示出意外差异。

结论

尽管显然验光、睫状肌麻痹验光、Allegro Oculyzer II和Allegro Topolyzer-Vario之间的柱镜轴位显示出统计学意义上的一致性，但仍会出现意外差异。
