Abstract

Purpose: To assess and compare the visual acuity and refractive outcomes of topography-guided laser in situ keratomileusis (LASIK) based on the fitting-shape-based refractive compensated and Phorcides software strategies.

Methods: Consecutive patients who underwent topography-guided LASIK were included in this study. Through double-masked simple randomization, patients were assigned to the Zhang & Zheng Auto-compensate Refraction (ZZ AR) group (the fitting-shape-based refractive compensated strategy using the ZZ AR calculator was used) or the Phorcides group (the topography analysis algorithm in Phorcides software [Phorcides LLC] was used). Only one eye per patient with binocular correction was randomly enrolled. The preoperative and postoperative visual acuities and refraction were analyzed at the 6-month follow-up visit.

Results: The ZZ AR and Phorcides groups comprised 156 and 147 eyes, respectively. At the 6-month postoperative follow-up visit, the median (range) absolute residual cylindrical refraction was 0.35 (1.01) and 0.47 (1.63) diopters (D) for the ZZ AR and Phorcides groups, respectively (P < .001). The percentages of patients with residual cylindrical power within 0.25 D were 29.49% and 13.61% for the ZZ AR and Phorcides groups, respectively (P = .001). Based on the percentages of patients with residual cylindrical powers within 0.50 and 1.00 D, the ZZ AR group showed better outcomes (P = .02 and .01). The percentage of patients with visual acuity better than 20/16 was significantly higher for the ZZ AR group than for the Phorcides group (P = .03).

Conclusions: The fitting-shape-based refractive compensated strategy for topography-guided LASIK procedures can better optimize the visual acuity and astigmatic refraction than the Phorcides software strategy. [J Refract Surg. 2024;40(5):e336-e343.].

地形图引导下的 LASIK：一项前瞻性研究。

目的：评估并比较地形图引导下的激光原位角膜磨镶术（LASIK）的视力和屈光效果，该方法基于基于拟合形状的屈光补偿策略和 Phorcides 软件策略：本研究纳入了接受地形图引导 LASIK 手术的连续患者。通过双掩蔽简单随机法，患者被分配到Zhang & Zheng Auto-compensate Refraction (ZZ AR)组（使用ZZ AR计算器的基于拟合形状的屈光补偿策略）或Phorcides组（使用Phorcides软件[Phorcides LLC]中的地形分析算法）。每名患者只随机选择一只眼睛进行双眼矫正。在 6 个月的随访中分析了术前、术后的视力和屈光度：ZZ AR组和Phorcides组分别有156只眼睛和147只眼睛。术后 6 个月随访时，ZZ AR 组和 Phorcides 组的绝对残余圆柱屈光度中位数（范围）分别为 0.35 (1.01) 和 0.47 (1.63) 二光度 (D)（P < .001）。ZZ AR 组和 Phorcides 组患者的残余圆柱力在 0.25 D 以内的百分比分别为 29.49% 和 13.61% （P = .001）。根据残余圆柱力在 0.50 和 1.00 D 以内的患者百分比，ZZ AR 组的疗效更好（P = 0.02 和 0.01）。ZZ AR组患者视力优于20/16的百分比明显高于Phorcides组（P = .03）：结论：在地形图引导的 LASIK 手术中，基于拟合形状的屈光补偿策略比 Phorcides 软件策略能更好地优化视力和散光屈光度。[J Refract Surg. 2024;40（5）：e336-e343]。
