Abstract

Purpose: To compare the effect of superior and temporal clear corneal incisions, regardless of the steep axis, on postoperative changes in corneal higher order aberrations (HOAs) in patients with healthy corneas and mild preoperative corneal astigmatism.

Methods: In this prospective cohort study, the right eyes of study participants were randomly assigned to one of two groups prior to cataract surgery: temporal incision (TI) and superior incision (SI). Preoperatively and 6 weeks after surgery, measurements were taken of corneal HOAs over a 6-mm optical zone.

Results: The study included 102 eyes (50 eyes in the TI group and 52 eyes in the SI group) that underwent routine phacoemulsification using a 2.4-mm clear corneal incision. Significant changes in vertical coma (P = .019), horizontal coma (P = .042), and vertical trefoil (P = .001) were observed in the SI group. In the subgroup analysis of the SI group, significant changes in vertical coma (P = .025) and vertical trefoil (P = .047) were observed in the eyes with preoperative with-the-rule corneal astigmatism, and significant changes in horizontal coma (P = .038) were observed in eyes with preoperative against-the-rule corneal astigmatism. The TI group showed no significant difference between the preoperative and postoperative periods.

Conclusions: The SI induced vertical and horizontal coma in accordance with the preoperative axis of the steep meridian. These alterations in corneal HOAs may affect the quality of vision after surgery. TI may potentially provide an advantage over SI in terms of corneal HOAs. [J Refract Surg. 2024;40(11):e792-e796.].

不同切口位置白内障手术后角膜高阶像差的变化：一项前瞻性随机研究

目的：比较上切口和颞侧透明角膜切口（无论陡轴如何）对角膜健康且术前有轻度角膜散光的患者术后角膜高阶像差（HOAs）变化的影响：在这项前瞻性队列研究中，研究对象的右眼在白内障手术前被随机分配到两组中的一组：颞切口组（TI）和上切口组（SI）。术前和术后 6 周，测量 6 毫米光学区域的角膜 HOAs：研究共包括 102 只眼睛（TI 组 50 只，SI 组 52 只），这些眼睛都接受了常规的超声乳化手术，采用 2.4 毫米透明角膜切口。在 SI 组中观察到垂直昏迷（P = .019）、水平昏迷（P = .042）和垂直三叶形（P = .001）的显著变化。在 SI 组的亚组分析中，观察到术前角膜散光为带规则散光的眼睛在垂直昏迷（P = .025）和垂直三叶形（P = .047）方面有显著变化，观察到术前角膜散光为反规则散光的眼睛在水平昏迷（P = .038）方面有显著变化。TI组在术前和术后无明显差异：SI诱导的垂直和水平昏迷与术前的陡经轴一致。角膜 HOAs 的这些改变可能会影响术后的视觉质量。就角膜HOAs而言，TI可能比SI更具优势。[J Refract Surg. 2024;40（11）：e792-e796]。

期刊介绍： The Journal of Refractive Surgery, the official journal of the International Society of Refractive Surgery, a partner of the American Academy of Ophthalmology, has been a monthly peer-reviewed forum for original research, review, and evaluation of refractive and lens-based surgical procedures for more than 30 years. Practical, clinically valuable articles provide readers with the most up-to-date information regarding advances in the field of refractive surgery. Begin to explore the Journal and all of its great benefits such as: • Columns including “Translational Science,” “Surgical Techniques,” and “Biomechanics” • Supplemental videos and materials available for many articles • Access to current articles, as well as several years of archived content • Articles posted online just 2 months after acceptance.
