To observe the decentration and tilt of implantable collamer lens (ICL) as well as possible visual effects postimplantation in primary iridociliary cysts.
The present investigation was a retrospective cohort study. All 48 patients (91 eyes) who underwent ICL surgery at the Center of Refraction Surgery of Tianjin Medical University Eye Hospital between July 2018 and May 2020 were split into two groups based on the absence or presence of primary iridociliary cysts established by ultrasonic biological microscopy (UBM) examination. Intraocular pressure (IOP), corrected distance visual acuity (CDVA), uncorrected distance visual acuity (UDVA), anterior chamber angle (ACA), anterior chamber volume (ACV), and anterior chamber depth (ACD) were recorded preoperatively and postoperatively at 1, 6, and 12 months. Additionally, we performed an analysis of the ICL vault, decentration, and tilt using a rotating Scheimpflug Oculus Pentacam camera system at 1, 6, and 12 months after surgery.
No serious complications were observed. Significant postoperative improvement ( < 0.05) of UDVA was established in the two studied groups; however, we did not observe statistically significant intergroup differences ( > 0.05) throughout the entire research period. In each group, the preoperative ACA, ACV, and ACD were statistically significantly reduced ( < 0.05), but no such decrease was established between their postoperative values ( > 0.05). We observed no statistical differences between both groups with regard to their values of IOP, ACA, ACV, ACD, ICL vault, ICL decentration, and tilt at 1, 6, and 12 months after surgery. Similarly, no statistically significant within-group correlation ( > 0.05) of the decentration of ICL and the tilt and the CDVA values was established.
No postimplantation effect of ICL with a central hole on vision was established in myopia patients with primary iridociliary cysts, within certain limits of ICL decentration and tilt values.
观察原发性虹膜睫状体囊肿患者植入可植入式胶原晶状体（ICL）后的偏心和倾斜情况以及植入后的可能视觉效果。
本研究为回顾性队列研究。将2018年7月至2020年5月在天津医科大学眼科医院屈光手术中心接受ICL手术的48例患者（91只眼），根据超声生物显微镜（UBM）检查有无原发性虹膜睫状体囊肿分为两组。记录术前及术后1、6和12个月的眼压（IOP）、矫正远视力（CDVA）、未矫正远视力（UDVA）、前房角（ACA）、前房容积（ACV）和前房深度（ACD）。此外，我们在术后1、6和12个月使用旋转式Scheimpflug Oculus Pentacam相机系统对ICL拱高、偏心和倾斜进行分析。
未观察到严重并发症。两个研究组术后UDVA均有显著改善（P<0.05）；然而，在整个研究期间，我们未观察到组间有统计学显著差异（P>0.05）。每组术前的ACA、ACV和ACD均有统计学显著降低（P<0.05），但术后值之间未出现这种降低（P>0.05）。我们观察到两组在术后1、6和12个月时的IOP、ACA、ACV、ACD、ICL拱高、ICL偏心和倾斜值无统计学差异。同样，ICL偏心和倾斜与CDVA值之间未建立组内统计学显著相关性（P>0.05）。
在原发性虹膜睫状体囊肿的近视患者中，在ICL偏心和倾斜值的一定范围内，未发现有中心孔的ICL植入对视力有植入后影响。
