Posterior chamber toric phakic intraocular lens implantation for high myopic astigmatism in eyes with pellucid marginal degeneration.

UNLABELLED: We report a case in which toric intraocular Collamer lenses (ICLs) effectively corrected the refractive errors of pellucid marginal degeneration (PMD). Preoperatively, in the patient's right eye, the manifest refraction was -10.5 -3.5 x 55, the uncorrected distance visual acuity (UDVA) was 20/1000, and the corrected distance visual acuity (CDVA) was 20/16; in the left eye, the manifest refraction was -11.0 - 6.5 x 130 and the UDVA and CDVA were 20/1000 and 20/20, respectively. After bilateral implantation of a toric ICL, in the right eye, the manifest refraction was +1.50 - 0.75 x 10, the UDVA was 20/16, and the CDVA was 20/12.5; in the left eye, the manifest refraction was +2.5 -3.25 x 125 and the UDVA and CDVA were 20/40 and 20/16, respectively. No sign of progressive disease and no vision-threatening complication were observed during the 6-month follow-up. Toric ICL implantation may be a viable surgical option for the correction of high myopic astigmatism in eyes with PMD.
