Iridociliary cysts do not impact on posterior phakic intraocular lens implantation for high myopia correction: A prospective cohort study in 1569 eyes.

ABSTRACT:

Purpose

To investigate the clinical characters and effect of iridociliary cysts among patients who had undergone posterior phakic intraocular lens implantation.

Methods

A total 1569 eyes of 866 high myopia patients, who underwent phakic intraocular lens implantation from 1 September 2011 to 31 August 2016, was included in this prospective cohort study. These patients were followed up for more than 12 months postoperatively.

Results

During the study period, 218 eyes (14%) of 154 patients were diagnosed with iridociliary cysts by ultrasound biomicroscopy. There were 74.3% patients with unilateral cysts and the cysts tended to have occurred in patients ages 20 to 30 years old (22%). The location of the cysts varied with temporal position as the most (50%) and superior position as the least (9.6%). After 1 week postoperative follow-up, there were no significant differences in clinical outcomes between the cysts group and no cysts group, but the proportion of 20/20 or better uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), and the 2 types of vector astigmatism. Intraocular pressure (IOP), refraction, and vault remained stable at different time points of the follow-up period, while vault of cysts patients tend to be lower than patients without cysts at more than 12 months.

Conclusions

Iridociliary cysts were more common than estimated and it had no impact on Phakic Intraocular Lens implantation because there was no clue to show significantly difference on postoperative clinical outcomes between the patients with and without iridociliary cysts in this study.

Project description:Purpose:To assess the efficacy and safety of a novel ophthalmic viscosurgical device-free (OVD-free) method for posterior chamber phakic intraocular lens (PIOL) implantation in myopic eyes. Methods:In this retrospective cohort study, the medical records of myopic eyes that underwent PIOL (Implantable Collamer Lens, ICL) implantation for myopia correction at the Eye Hospital of Wenzhou Medical University between May 2015 and March 2017 were reviewed. A total of 49 eyes with complete data that met follow up requirements (2?h, 1?day, 1?week, 3?months postoperatively) were recruited. Based on the surgical techniques used, the eyes were divided into the OVD-free method group and the standard method group. The clinical data, including intraocular pressure (IOP), corrected distance visual acuity (CDVA) and spherical equivalent (SE), at each follow-up were collected for comparison. Endothelial cell loss and complications were also investigated. Results:Twenty-one eyes received the standard method, and 28 eyes received the OVD-free method. A rise in IOP >?22?mmHg at 2?h was noted in 14 eyes (66.7%) in the standard group and none (0%) in the OVD-free group (p?<?0.001). The rise in IOP from baseline was significantly higher at 2?h in the standard group (10.5?±?5.2?mmHg vs. 2.2?±?3.3?mmHg, difference: 8.3, 95% CI 5.8 to 10.8; p <?0.001). There was a significant difference in the time course of LogMAR CDVA changes between the two groups (p?=?0.047). The LogMAR CDVA was significantly better in the OVD-free method group compared to the standard group at 1?day (-?0.076, 95% CI -?0.134 to -?0.018; p?=?0.012), 1?week (-?0.071, 95% CI -?0.135 to -?0.007; p?=?0.03), but not at 3?months (-?0.046, 95% CI -?0.107 to 0.015; p?=?0.134). There was no significant difference in the time course of SE changes between the two groups (p?=?0.471; p?=?0.705). In the OVD-free group, mean endothelial cell loss was 4.6% at 3?months (2522?±?281 vs. 2407?±?226 cells/mm2, difference: -115, 95% CI -?295 to 65; p?=?0.187). No complications were reported in both groups except for the early IOP elevation in the standard group during the observation period. Conclusions:The OVD-free method is safe and efficient for ICL implantation. It can be a safer method of ICL implantation compared to the standard method in that it completely eliminates ophthalmic viscoelastic devices-related complications without causing additional complications.
