Visual Prognosis Following Cataract Surgery in Highly Myopic Patients with Prior History of Verisyse Phakic Intraocular Lens Implantation.

ABSTRACT: Background/Objectives: This study aimed to evaluate the visual outcomes and prognosis after cataract surgery in patients with prior history of Verisyse phakic intraocular lens (pIOL) implantation. Methods: A retrospective cohort study involving 215 Verisyse pIOL implantations and 17 explantations was conducted. The Verisyse pIOL was disenclaved and removed through a superior scleral tunnel incision. Cataract extraction with phacoemulsification was then performed through a temporal clear corneal incision. Results: An occurrence rate of 7.9% of eyes with cataract formation was found. Both uncorrected (UDVA) and corrected visual acuity (CDVA) three months after cataract surgery were significantly improved (0.24 ± 0.30 vs. 0.73 ± 0.48; p < 0.001 and 0.10 ± 0.14 vs. 0.30 ± 0.31; p = 0.004, respectively). The UDVA was 20/20 or better in 41% of eyes and 20/40 or better in 65% of eyes. The CDVA was 20/20 or better in 53% of eyes and 20/40 or better in 88% of eyes. The safety and efficacy indices were 1.96 ± 1.68 and 1.60 ± 1.36, respectively. Conclusions: Various complications including cataracts may develop in these patients. Verisyse pIOLs have a lower incidence of cataract formation and are more likely to lead to age-related cataracts rather than the anterior subcapsular cataracts commonly seen in implantable collamer lens (ICL) patients. Patients with a prior history of Verisyse pIOL can expect to have a good visual prognosis after cataract extraction.

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.
