摘　　要：目的评价Oculyzer眼前段分析系统引导的个体化准分子激光原位角膜磨镶术（LASIK）矫正准分子激光偏中心切削的临床效果。方法回顾性分析。对16例（21只眼）角膜屈光偏中心切削者行Oculyzer引导的个体化LASIK进行矫正，比较手术前后裸眼视力、光学切削偏中心数值、角膜表面变异指数、角膜表面垂直不对称指数、角膜形态等指标。结果术后裸眼视力均明显提高；偏中心数值由术前的1．4—2．6mm，平均（2．05±0．55）mm减少到术后3个月的0．06—0．28mm，平均（0．18-t-O．12）mm（t=2．858，P=0．005）；角膜表面变异系数及角膜高度的不对称指数均较术前明显降低（t=2．137，P：0．005，0．017）；所有眼偏中心切削均被矫正，视觉质量改善。结论0c．ulyzer引导的个体化手术矫正准分子激光偏中心切削安全有效。Objective To evaluate the clinical efficacy of Oculyzer-guided customized LASIK for eccentric cutting induced by keratorefractive surgery. Methods Twenty-one eyes of 16 patients with eccen- tric cutting induced by keratorefractive surgery were enrolled in this retrospective study and were treated with Oculyzer-guided customized LASIK. The uncorrected visual acuity （UCVA） , the value of optical eccentric cutting, index of surface variance（ ISV）, index of vertical asymmetry（IVA） and corneal topography were an- alyzed and compared between before and after operation. Results The UCVA was improved significantly in all patients. The value of optical eccentric cutting changed significantly from 1.4 - 2.6 mm （ average 2.05±0.55mm） before operation to 0.06 -0.28 mm （ average 0.18 ±0.12 mm） at 3 months after operation. The ISV and IVA decreased significantly compared with that of pre-operation. The eccentric cutting was corrected in all eyes after operation, and the visual quality was improved. Conclusion Oculyzer-guided customized LASIK is a safe and effective surgery for eccentric cutting induced by keratorefraetive surgery.
