摘要 目的探讨角膜波前像差引导联合Q值优化的最优个性化角膜屈光矫正程序(ORK—CAM)引导的非球面切削准分子激光上皮下角膜磨镶术(LASEK)治疗角膜薄的高度近视临床疗效。方法运用角膜波前像差引导联合Q值优化的ORK—CAM及小光斑高速飞点激光扫描系统对49例76只眼角膜薄的高度近视患者行LASEK。术后2周,1月,3及6月检查裸眼视力、验光、Haze等级。术后半年时复查角膜地形图、波前像差、视觉对比敏感度并进行满意度调查。结果术前平均最佳眼镜矫正视力(BSCVA)为1.10+0.12,术后6月BucVA(BucVA)为1.12+0.17。术后平均模拟角膜记读数(SimK)等效值、慧差、球差、总体像差分别增加了一13.5%、93.87%、172.22%、23.81%、43.28%,较术前差异有统计学意义。角膜地形图形态有92.11%为同心圆型,视觉质量满意度为95.92%。结论角膜波前像差引导的LASEK治疗角膜薄的高度近视,术后3个月以后平均视力稳定,且好于术前BCVA。术后6月时平均总波前像差增加百分比较小,球差增加较少,较好的保持了角膜的的非球面性。术后患者出现眩光、夜视力差的机率较低,具有较好的临床疗效。 Objeetive To discuss the clinical curative effect of corneal wavefront-guided combining Q- value guided aspheric keratectomy excimer laser subepithelial keratomileusis (LASEK) of ORK-CAM (Optimized Refi'active Keratectomy Customized Ablation Manager, ORK-CAM) in treatment for high my- opia with thin cornea. Methods Corneal wavefront-guided combining Q- value guided aspheric keratectomy excimer laser subepithelial keratomileusis (LASEK)of ORK-CAM were used in 76 eyes of 49 patients who were high myopia with thin cornea. UCVA (uncorrected visual acuity, UCVA), optometry, level of haze were observed at 2, 4 weeks, 3, 6 months post-operation. Topography, wave~ont aberration, Visual contrast sensitivity and investigation of Satisfaction were reviewed 6 months post-operation. Results BSCVA (best spectacle-corrected visual acuity, BSCVA)was 1.10+0.12 preoperative, and UCVA was 1.12+0.17 at 6 months after operation. Simk (sinulated keratometry, SimK) of equivalent value, Coma-like, spherical-like, RMSg (root of mean square of general aberration) increased -13.5%, 93.87%, 172.22%, 23.81%, 43.28% postoperative respectively. Compared with preoperation, these data all had statistical significance. 92.11% eyes of postoperative topography were central uniform type. 43.87% patients were satisfied with the quality of vi- sion. Conclusions Corneal wavefront-guided combining Q- value guided aspheric keratectomy excimerlaser subepithelial keratomileusis (LASEK)of ORK-CAM for high myopia have a stable vision after 3 months of surgery, and better than preoperative UCVA. The RMSg, Sqrab increased a little 6 months after operation. The rate of Glare, Bad night vision was low. Corneal wavef~ont aberration-guided aspheric keratectomy excimer, ORK-CAM have a good clinical curative effect.
