Abstract

Purpose: To compare the objective visual quality of moderate-to-high myopia corrected by small incision lenticule extraction (SMILE) and transepithelial photorefractive keratectomy (TransPRK) at a 1,050-Hz ablation frequency, assisted by Smart-Pulse technology (SCHWIND eye-tech-solutions).

Methods: This study involved 123 patients (123 eyes) with moderate-to-high myopia between July 2020 and January 2021. They were categorized into the SMILE group (67 patients, 67 eyes) and the TransPRK group (56 patients, 56 eyes). Follow-ups were conducted at 6 months postoperatively to record the logarithm of the minimum angle of resolution visual acuity, and the Strehl ratio and higher order aberrations were measured using the Sirius anterior segment analysis device (SCHWIND eye-tech-solutions) under a 6-mm pupil diameter at various postoperative intervals.

Results: At 1 week and 1 month postoperatively, the uncorrected distance visual acuity (UDVA) in the SMILE group was superior to that in the TransPRK group (P < .05 for both). At 1 week and 1 month postoperatively, the Strehl ratio value in the SMILE group was higher than that in the TransPRK group (P < .05 for both). At 1, 3, and 6 months postoperatively, coma was greater in the SMILE group than in the TransPRK group (P < .05 for all). Spherical aberrations were lower in the SMILE group than in the TransPRK group at 3 and 6 months postoperatively (P < .05). At 6 months postoperatively, UDVA was -0.09 ± 0.08 and -0.11 ± 0.05 logMAR in the SMILE and TransPRK groups, respectively, which exceeded their preoperative corrected distance visual acuity of -0.05 ± 0.04 and -0.09 ± 0.08 logMAR (all P < .001). Compared with preoperative values, the Strehl ratio, total higher order, coma, and spherical aberration differences were significantly increased postoperatively in both groups (all P < .001).

Conclusions: Both surgical methods improved UDVA and each had its advantages. The visual quality of SMILE was superior at 1 week and 1 month postoperatively (Strehl ratio values were higher than those of the TransPRK group), and its spherical aberration was lower than that of the TransPRK group at 3 and 6 months; TransPRK with SmartPulse technology with a 1,050-Hz ablation frequency showed that coma was significantly lower than that of the SMILE group at 1, 3, and 6 months postoperatively.

以 1,050-Hz 频率消融治疗中高度近视的 SMILE 和 SmartPulse 技术辅助 TransPRK 的客观视觉质量比较。

目的：比较在智能脉冲技术（SCHWIND eye-tech-solutions）辅助下，通过小切口皮瓣摘除术（SMILE）和频率为1,050 Hz的经上皮光屈光性角膜移植术（TransPRK）矫正中高度近视的客观视觉质量：本研究涉及 2020 年 7 月至 2021 年 1 月期间的 123 名中度至高度近视患者（123 只眼睛）。他们被分为 SMILE 组（67 名患者，67 只眼睛）和 TransPRK 组（56 名患者，56 只眼睛）。术后6个月进行随访，记录最小分辨角视力的对数，并在术后不同时间段使用Sirius眼前节分析仪（SCHWIND eye-tech-solutions）在6毫米瞳孔直径下测量Strehl比值和高阶像差：结果：术后1周和1个月，SMILE组的未矫正远视力（UDVA）优于TransPRK组（两者的P < .05）。术后1周和1个月时，SMILE组的Strehl比值高于TransPRK组（两者的P均<0.05）。术后 1 个月、3 个月和 6 个月时，SMILE 组的昏迷程度高于 TransPRK 组（P 均＜0.05）。术后 3 个月和 6 个月，SMILE 组的球差低于 TransPRK 组（P < .05）。术后 6 个月时，SMILE 组和 TransPRK 组的 UDVA 分别为 -0.09 ± 0.08 和 -0.11 ± 0.05 logMAR，超过了术前校正距离视力 -0.05 ± 0.04 和 -0.09 ± 0.08 logMAR（所有 P < .001）。与术前值相比，两组患者术后的Strehl比值、总高阶、昏迷和球差均显著增加（均P < .001）：结论：两种手术方法都能改善 UDVA，且各有优势。结论：两种手术方法都能提高 UDVA，各有优势。SMILE 组术后 1 周和 1 个月的视觉质量更好（Strehl 比值高于 TransPRK 组），术后 3 个月和 6 个月的球差低于 TransPRK 组；采用 SmartPulse 技术的 TransPRK，消融频率为 1,050 Hz，术后 1、3 和 6 个月的昏迷明显低于 SMILE 组。[J Refract Surg. 2024;40（7）：e490-e498]。
