Abstract Details


To investigate the incidence of iridociliary cysts in patients who are candidates for Implantable Collamer Lens (ICL) surgery. Although iridociliary cysts are asymptomatic in most of cases, it is important to preoperatively perform ultrasound biomicroscopy (UBM) to determine their incidence and investigate the safety of implanting a posterior chamber ICL in these patients.


Cleveland Clinic Abu Dhabi, UAE


A total of 112 patients (224 eyes) who were candidates for ICL implantation surgery were evaluated in this retrospective study. Perioperative examination included uncorrected distance visual acuity, corrected distance visual acuity, refractive error, slit lamp examination, intraocular pressure, gonioscopy, corneal tomography, endothelial cell density, anterior chamber depth , horizontal white to white and UBM measurements. Preoperative UBM examination, as the most effective method for iridociliary cyst detection, was done for each patient by the same ultrasonography specialist. The number, size and location of the cysts were recorded.


Iridociliary cysts were detected in 28 eyes (12.5%) of 23 patients (19 eyes of 16 females, 9 eyes of 7 males). Prevalence was 20.5% (16 females and 7 males). There were 18 (78.2%) patients with unilateral cysts and 5 (21.7%) patients with bilateral cysts. The mean age of the subjects was 30.86 ± 6.41 years and manifest refraction spherical equivalent was -6.03 ± 3.54 D. Among 23 patients with cysts, 7 (30.4%) patients underwent binocular ICL implantation. Only 1 patient (14.2%) required ICL repositioning due to posterior iris chafing of the ICL as a result of multiple ciliary body cysts.


In our study, we found the incidence of iridociliary cysts in our population of ICL candidates to be 20.5% and were more commonly diagnosed in women (69.5%). Of the 7 patients with iridociliary cysts who underwent binocular ICL implantation, only 1 patient (14.2%) developed an adverse event after ICL implantation due to multiple ciliary body cysts. Iridocyliary cysts are not an absolute contraindication for ICL surgery. Determination of the size and location of the cysts is integral to deciding whether or not to proceed with ICL surgery.
