We present 2 cases of toric intraocular lens implantation for keratoconus: A 55-year-old man with forme fruste keratoconus with a preoperative uncorrected distance visual acuity (UDVA) of 20/800 and a refraction of -6.50-3.00x135 and a 46-year-old man with a claw-shaped topographic pattern, a family history of keratoconus, and a UDVA of 20/800 with a refraction of -5.00-3.00x85. The refraction had been stable for at least 5 years in both patients. Phacoemulsification and implantation of an acrylic toric IOL were uneventful. One year postoperatively, the UDVA was 20/25 in both cases, with a refraction of -0.25-0.50x140 and 0.25-0.50x60, respectively. No progression and no IOL rotation were observed. Toric IOLs may provide excellent outcomes in patients with stable and nonprogressive corneal ectasia.
