摘　　要：目的观察VISX StarS3准分子激光原位角膜磨镶术治疗中高度散光的有效性、可预测性及安全性。方法采用回顾性的研究方法对25例36只眼首次接受VISX StarS3准分子激光原位角膜磨镶术的患者进行分析，入选患者散光均在2．0D以上且无角膜瓣并发症，术后随访至少6个月以上，观察术后裸眼视力、最佳眼镜矫正视力、残余散光度、散光的向量改变以及术后眩光发生情况。结果术前柱镜度平均（-2．65±0．70）D（-2．0—4．25D），平均球镜度（-6．28±3．05）D，范围＋0．5～13．25D；术后83．3％视力在1．0以上，97．2％视力在0．5以上；16．7％最好矫正视力下降1行，没有出现最佳矫正视力下降超过1行的情况。术后平均残余散光度（0．46±0．44）D（0～1．25D），58．3％残余散光在±0．5D以内，94．4％残余散光在±1．0D以内，平均矫正指数为（0．98±0．18），平均失误角（3．30±3．8）度。25例中，6例患者术后至少有1只眼出现持续的夜间视力障碍或眩光。结论VISX StarS3准分子激光原位角膜磨镶术治疗中高度散光有良好的有效性、可预测性及安全性，但仍有相当比例的患者发生夜间眩光。Objective To investigate the efficacy,predictability, and safety of laser in situ keratomileusis （LASIK） to correct moderate and high astigmatism with VISX Star S3. Methods We retrospectively studied 36 eyes of 25 patients who received primary LASIK using VISX Star S3 excimer laser, and the astigmatism of included eyes was at lest -2.00 diopters （D）and without flap complication. Follow-up was at least 6 months.Primary outcome measures included uncorrected visual acuity（UCVA）, best spectacle-corrected visual acuity（BSCVA ）, manifest refraction, an assessment of astigmatic correction through vector analysis, and the incidence of night glare.Results Preoperatively,the mean spherical component of refraction was （-6.28± 3.05 ）D （ range, ＋0.5 to - 13.25D ）, the mean refractive cylinder was （ -2.65 ± 0.70 ）D （range, -2.0 to -4.25D ）. Postoperatively, 97.2% had an uncorrected visual acuity of 0.5 or greater, whereas 83.3 % demonstrated an uncorrected visual acuity of 1.0 or greater. 16.7% of eyes lost 1 line of best spectacle-corrected visual acuity, and no eyes lost greater than 1 line of BSCVA. The mean refractive cylinder was （0.46± 0.44）D （range,0 to 1.25 D） with 58.3% ± 0.50 D and 94.4% ±1.00 D of intended. Vector analysis showed that mean correction index （CI） was 0.98± 0.18 with a mean angle of error of 3.30± 3.8 degrees. 6/25 of patients suffered a lasted night glare at least one eye. Conclusins LASIK with the VISX Star S3 excimer laser is effective,reasonably predictable, and safe for correction of moderate and high astigmatism, however, night glare of complains were not seldom.
