A posterior chamber phakic refractive lens dislocated into the vitreous

Abstract

Significance We present a unique cause for zonular dehiscence, which provides a pathway for subsequent dislocation of an implanted phakic refractive lens (PRL) into the vitreous cavity. Purpose To determine the cause of zonular dehiscence and to avoid similar complications after PRL implantation in the future. Case Report A 37-year-old highly myopic patient with refraction of −24.0 DS in both eyes received PRL implantation in both eyes. In the 14-month postoperative follow-up, it was found that the PRL dislocated into the vitreous cavity. The patient then underwent phacoemulsification and vitrectomy. The patient was treated successfully. No ocular complication was found. The visual acuity of the left eye was 20/40, two weeks after surgery. Conclusions We report a unique cause for zonular dehiscence, and the clarification of its detailed characteristics may contribute to prevention of such a complication in the future.
