title: Combined corneal collagen cross-linking and posterior chamber toric implantable collamer lens implantation for keratoconus.
abstract: A 29-year-old woman with keratoconus underwent posterior chamber toric implantable Collamer lens (Visian ICL; STAAR Surgical, Monrovia, CA) implantation 12 months after corneal collagen cross-linking with riboflavin and ultraviolet radiation-A. No intraoperative or postoperative complications were observed. Three months postoperatively, uncorrected distance visual acuity improved from counting fingers to 20/40 and corrected distance visual acuity improved from 20/100 to 20/30. Combined cross-linking treatment and posterior chamber toric phakic Collamer lens implantation in a two-step procedure seems to be an effective method for correcting keratoconus in patients with high myopia and astigmatism. Despite the encouraging results, longer follow-up is necessary to evaluate the outcomes of this approach.
