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.
