Iris-fixated phakic intraocular lens implantation in an adult with retinopathy of prematurity: 1-year follow-up

Abstract

To report a case of iris-fixated phakic intraocular lens (pIOL) implantation in a patient with an extremely steep cornea, shallow anterior chamber, and small corneal diameter caused by retinopathy of prematurity (ROP) and scleral encircling. Case report. Iris-fixated pIOLs were implanted in a 19-year-old patient with refraction of -18.5 -0.75 x 180 in the right eye and -15.5 -1.25 x 180 in the left eye. The keratometric values were 53.50 and 51.25 diopters (D) in the right eye and 54.75 and 51.75 D in the left eye. The white-to-white diameter and anterior chamber depth were 10.6 and 3.37 mm, respectively, in the right eye and 10.5 and 3.33 mm, respectively, in the left eye. A small pIOL was used to guarantee a safety distance and resulted in a one-line gain in uncorrected distant visual acuity and stable endothelial cell density 1 year after surgery. An iris-fixated pIOL Vis therefore an effective option for myopic patients with ROP.
