【摘要】：【目的】对Q值引导个性化LASIK（Q-value guided custiomizedLASIK， Q-LASIK）及标准化LASIK（Standardized LASIK， S-LASIK）两种手术方式在近视治疗上的临床效果进行回顾性比较与分析。 【方法】选取2011年5月至2012年2月间于我院行Q-LASIK术后3个月20例40眼，S-LASIK术后术后3个月20例40眼。随访并比较分析术前1周和术后1个月及术后3个月时患者的裸眼视力、矫正视力、屈光度、角膜Q值及患者主观感受满意度。 【结果】两组术前及术后随访结果：（1）安全性：Q-LASIK术后3月无1例出现最佳矫正视力下降，S-LASIK仅有1例下降，安全性指数分别为1.047和1.024；（2）有效性：术后3月两组裸眼视力均大于等于1.0，均达到预期值，有效性指数均约为0.99；（3）可靠性：术后1月～术后3月，两组术后等效球镜度均无明显改变，，两组间比较无统计学差异(P0.05)；（4）术后3月岁让，两组Q值叫术前均明显增加（P0.05），Q-LASIK组增加值△Q明显低于S-LASIK组(P0.05)；（5）术后1周及3月随访，Q-LASIK组主观视觉质量反馈较S-LASIK组稍高（P0.05）。 【结论】通过比较发现两种术式的安全性、有效性及可靠性均较好，均可有效的改善近视患者的视觉；而Q-LASIK术式相较S-LASIK术式，术后角膜形态改变较少，且差异较显著；患者主观视觉感受上Q-LASIK组更佳。为了跟进一步量化评价两种手术在视觉质量上的差别，还需要跟多的病例及更全面的评价指标，例如对比敏感度等。
[Abstract]:[objective] to compare and analyze the clinical effect of Q guided individualized LASIK (Q-value guided custiomizedLASIK, Q-LASIK) and standardized LASIK (Standardized LASIK, S-LASIK in myopia treatment. [methods] from May 2011 to February 2012, 20 cases (40 eyes) and 20 cases (40 eyes) were treated with Q-LASIK in our hospital 3 months after operation and 3 months after S-LASIK. The uncorrected visual acuity, corrected visual acuity, diopter, corneal Q value and subjective feeling satisfaction of the patients were compared and analyzed 1 week before operation, 1 month after operation and 3 months after operation. [results] the two groups were followed up before and after operation: (1) Safety: no case had the decline of best corrected visual acuity (BCVA) in 3 months after Q-LASIK, only 1 case of S-LASIK decreased, the safety index was 1.047 and 1.024 respectively. (2) effectiveness: the uncorrected visual acuity of the two groups was more than 1.0 at 3 months after operation, reaching the expected value, and the validity index was about 0.99; (3) Reliability: from 1 month to 3 months after operation, there was no significant change in the equivalent spherical degree between the two groups, and there was no statistical difference between the two groups (P0.05). (4) at the age of 3 months after operation, the Q value of the two groups increased significantly before operation (P0.05), and that of the Q-LASIK group was significantly lower than that of the S-LASIK group (P0.05). (5) after 1 week and 3 months follow-up, subjective visual quality feedback in Q-LASIK group was slightly higher than that in S-LASIK group (P0.05). [conclusion] it is found that the two methods are safe, effective and reliable, and can improve the vision of myopia patients effectively, but the corneal morphology of Q-LASIK is less than that of S-LASIK, and the difference is significant. Q-LASIK group was better in subjective visual perception. In order to compare with the further quantitative evaluation of the visual quality of the two operations, it is necessary to have more cases and more comprehensive evaluation indicators, such as contrast sensitivity, etc.
