Abstract
Purpose. To analyze the safety, effectiveness, and stability of triplex surgery for phakic 6H anterior chamber phakic intraocular lens explantation and phacoemulsification with in-the-bag IOL implantation for super high myopia in long-term observations. Methods. This retrospective case series evaluated 16 eyes of 10 patients who underwent triplex surgery. Best corrected visual acuity (BCVA), endothelial cell density (ECD), and associated adverse events were evaluated. Results. The mean follow-up time after the triplex surgery was 46 ± 14 months. The mean logMAR BCVA was significantly improved after triplex surgery (P = 0.047). One eye developed endophthalmitis five days postoperatively and underwent pars plana vitrectomy (PPV). Five eyes with preoperative severe endothelial cell loss developed corneal decompensation and underwent keratoplasty at a mean time of 9.4 ± 2.6 months after the triplex surgery. One eye had graft failure and underwent a second keratoplasty. The eye developed rhegmatogenous retinal detachment and underwent PPV with silicone oil 18 months later. ECD before the triplex surgery was not significantly different compared with that at last follow-up (P = 0.495) apart from these five eyes. Three eyes (18.8%) developed posterior capsule opacification. Conclusions. Triplex surgery was safe and effective for phakic 6H related complicated cataracts. Early extraction before severe ECD loss is recommended.
Highlights
Anterior chamber angle-supported phakic intraocular lenses (AC pIOLs) were once widely accepted as an effective option for the correction of high myopia [1]
We retrospectively reviewed 16 eyes of 10 patients who were previously implanted with phakic 6H AC pIOL (Ophthalmic Innovations International, Ontario, CA) for the correction of super high myopia and developed lens opacity undergoing triplex cataract surgery from July 1, 2008, to June 30, 2012, at Eye & ENT Hospital of Fudan University, Shanghai, China
The present study showed that triplex surgery of phakic 6H AC pIOL explantation and phacoemulsification with in-the-bag IOL implantation was an effective means for improvement of vision and refraction in agreement with previous studies [9,10,11]
Summary
Anterior chamber angle-supported phakic intraocular lenses (AC pIOLs) were once widely accepted as an effective option for the correction of high myopia [1]. They offer accurate and stable refraction, preserve the shape of the cornea, preserve accommodation of the crystalline lens, and are potentially reversible compared to laser keratorefractive or refractive lens exchange procedures [2]. The best corrected visual acuity (BCVA), refraction, and contrast sensitivity are all improved in the short-term reports [4,5,6] It was used globally since 1990s and was popular in China since 2002. We provide the longest follow-up term after explantation of AC pIOLs and Journal of Ophthalmology evaluate its safety, effectiveness, and stability, which might alert ophthalmologists to closer postoperative surveillance and help surgeons to determine the optimal surgical time
