摘要

目的比较飞秒LASIK手术中虹膜定位与Kappa角矫正的临床疗效。方法前瞻性随机对照研究。采用匹配t检验对两组术后1个月视力、对比敏感度分别与术前最佳矫正视力、最佳矫正视力配戴眼镜测量对比敏感度。采用两个独立样本t检验和非参数检验对两组患者术后1个月的视力、与术前最佳矫正视力比较的对比敏感度、配戴最佳矫正视力眼镜的对比敏感度增加值和Pentacam测量的截心值对进行比较。两组术后1个月的视力、对比敏感度增加值用Pentacam测量截心值，术后残余球面镜、透镜镜和柱面镜轴进行相关性分析。结果两组术后1个月视力、对比敏感度与术前最佳矫正视力、最佳矫正视力配戴眼镜测量对比敏感度差异有统计学意义。两组术后1个月视力、对比敏感度及Pentacam测量截心值差异均无统计学意义。结论两种手术方式均可有效避免LASIK中心割裂，术后视力及对比敏感度均优于术前。两种手术方式术后的视力、对比敏感度增加值和切断中心无差异。关键词:飞秒激光;虹膜定位;卡帕角校正

Clinical curative effect comparison of the iris localization and Kappa angle correction femtosecond LASIK

Objective To compare the clinical curative effect of iris localization and Kappa Angle correction on femtosecond LASIK surgery. Methods Prospective randomized controlled study. Matching t test was used on two groups of postoperative 1 month visual acuity, contrast sensitivity respectively and preoperative best corrected visual acuity, best corrected vision wear glasses measuring contrast sensitivity. Two independent sample t test and nonparametric test were used on between the two groups of postoperative 1 month visual acuity, contrast sensitivity compared with preoperative best corrected visual acuity, best corrected vision wear glasses contrast sensitivity increased value and Pentacam measurement of cutting off center value pairs. Two groups of postoperative 1 month visual acuity, contrast sensitivity increased value with Pentacam measurement of cutting off center value, postoperative residual spherical mirror, l enticular mirror and cylindrical mirror axis for correlation analysis. Results Two groups of postoperative 1 month visual acuity, contrast sensitivity and preoperative best corrected visual acuity, best corrected vision wear glasses measuring contrast sensitivity difference was statistically significant. Between the two groups of postoperative 1 month visual acuity, contrast sensitivity and Pentacam measurement of cutting off center value differences had no statistical significance. Conclusions The two kinds of operation method can effectively avoid cutting off center of LASIK, get better than that of preoperative vision and contrast sensitivity. Two kinds of operation method postoperative visual acuity, contrast sensitivity increase value and cutting off center has no difference. Key words: Femtosecond laser; The iris localization; Kappa Angle correction

期刊介绍： China Practical Ophthalmology was founded in May 1983. It is supervised by the National Health Commission of the People's Republic of China, sponsored by the Chinese Medical Association and China Medical University, and publicly distributed at home and abroad. It is a national-level excellent core academic journal of comprehensive ophthalmology and a series of journals of the Chinese Medical Association. China Practical Ophthalmology aims to guide and improve the theoretical level and actual clinical diagnosis and treatment ability of frontline ophthalmologists in my country. It is characterized by close integration with clinical practice, and timely publishes academic articles and scientific research results with high practical value to clinicians, so that readers can understand and use them, improve the theoretical level and diagnosis and treatment ability of ophthalmologists, help and support their innovative development, and is deeply welcomed and loved by ophthalmologists and readers.
