Abstract

Purpose: To assess the short-term impact of stand-alone MINIject (iSTAR Medical SA) implantation on astigmatism in a single-center retrospective study.

Methods: Refractive and corneal astigmatism was investigated based on preoperative and postoperative subjective refraction and Scheimpflug tomography measurements at 3 months (D90) using power vectors: the spherical equivalent M and the Jackson cross cylinder projections to the 0° and 90° (J₀) and to the 45° and 135° meridian (J₄₅).

Results: A total of 60 eyes with glaucoma or ocular hypertony from 54 patients were included. Refractive cylinder did not change after stand-alone implantation (C_D0 = -1.48 ± 1.52 diopters [D] vs C_D90 = -1.36 ± 1.20 D, P = .30) and, analogously, no time course was observed in three-dimensional vector analysis (P > .99). Anterior corneal surface astigmatism showed a near-significant change (P = .07) in the two-dimensional vector analysis (J₀; J₄₅), primarily driven by the J₀ component (P = .03), whereas the posterior surface remained unaffected (P = .4). The mean absolute surgically induced astigmatism was 0.78 ± 0.53 D for the anterior surface and 0.22 ± 0.21 D for the posterior surface.

Conclusions: Supraciliary MINIject implantation may induce minor short-term changes in anterior corneal astigmatism. However, when implanted as a stand-alone procedure, it does not affect refractive astigmatism. Therefore, astigmatic changes do not require specific emphasis during patient counseling.

微创青光眼手术中睫上引流装置植入后的屈光和角膜散光。

目的：通过单中心回顾性研究，评估独立MINIject （iSTAR Medical SA）植入术对散光的短期影响。方法：基于术前和术后主观屈光和3个月（D90） Scheimpflug断层扫描测量，使用功率向量：球面等效M和Jackson十字柱面投影到0°和90°（J0）和45°和135°子午线（J45），研究屈光和角膜散光。结果：共纳入54例青光眼或高眼压患者60只眼。单独植入术后屈光柱无变化（CD0 = -1.48±1.52屈光度[D] vs CD90 = -1.36±1.20 D, P = 0.30），三维矢量分析无时间变化（P = 0.99）。在二维矢量分析（J0; J45）中，角膜前表面散光显示出接近显著的变化（P = .07），主要由J0分量驱动（P = .03），而角膜后表面未受影响（P = .4）。手术引起的平均绝对散光前表面为0.78±0.53 D，后表面为0.22±0.21 D。结论：睫状体上微珠植入可引起角膜前散光的轻微短期改变。然而，当作为一个独立的程序植入时，它不会影响屈光散光。因此，在患者咨询时，散光的改变不需要特别强调。

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.
