Long-term Complications of Posterior Chamber Phakic Refractive Lenses: Case Report and Literature Review

This article presents two cases of phakic refractive lens (PRL) complications in China. Case 1 presents a highly myopic patient with PRL's footplate partly subluxated into the anterior chamber by blunt trauma one year after implantation. The PRL was repositioned successfully without other complications. Case 2 represents a case of pigment dispersion glaucoma developed seven years after PRL implantation. Intraocular pressure (IOP) lowering therapy was initiated and the IOP continued to be in the normal range for both affected eyes with ongoing follow-up. The preciseness in sulcus-to-sulcus measurements is important to minimize the risk of dislocation and crystalline lens touch; thus, a careful preoperative evaluation should be performed to exclude the presence of glaucoma, and the patients undergoing the procedure need to be informed about the increased risk for glaucoma. In summary, a comprehensive ophthalmic evaluation is essential to optimize both patient and PRL selection to minimize the risk for potential complications, and the PRL implantation warrants long-term follow-up.
