Iris-fixated phakic intraocular lens implantation for correction of high myopia in microspherophakia.

摘要

We report the refractive correction of high myopia in a 23-year-old patient with idiopathic microspherophakia using iris-fixated phakic intraocular lenses (pIOLs) (Verisyse/Artisan). Four years after bilateral implantation, the uncorrected distance visual acuity was 20/25 with a correction of 20/20(-1) in both eyes. No intraoperative or postoperative complications occurred. Iris-fixated pIOLs are not recommended for every patient with microspherophakia. However, this procedure may be an option in microspherophakic patients with appropriate anterior chamber depth and no history of lens dislocation who are likely to comply with annual eye examinations. Follow-up should include monitoring the endothelial cell count and biomicroscopy for adequate space between the pIOL, the natural crystalline lens, and the corneal endothelium. Scheimpflug photography can be a valuable tool in such cases.
