A toric intraocular Collamer lens (ICL) was used to correct myopic astigmatism after penetrating keratoplasty. The patient's manifest refraction improved from -8.0 -1.75 x 170 preoperatively, with an uncorrected distance visual acuity (UDVA) of 0.15 and a corrected distance visual acuity (CDVA) of 0.4, to +0.75 -0.50 x 130 postoperatively, with a UDVA of 0.8 and a CDVA of 1.0. No serious complications or refractive changes occurred during the 1-year follow-up. Implantation of a myopic toric ICL in phakic eyes is an option to correct postkeratoplasty anisometropia and astigmatism.
