Abstract

The present study reports the use of a phakic toric Implantable Collamer Lens (ICL) that improved the refraction correction of high myopia and astigmatism in a case of keratectasia following corneal cross‑linking. A 31‑year‑old male was diagnosed with keratectasia 12 years after laser‑assisted in situ keratomileusis (LASIK). Following LASIK, the manifest refraction was ‑3.50‑2.25x90 [0.1 logarithmic expression (LogMAR) best corrected visual acuity (BVCA)] in the right eye and ‑8.00‑3.50x175 (0.3 LogMAR BCVA) in the left eye, with a LogMAR uncorrected distance visual acuity (UDVA) of 0.8 and a ‘counting fingers’ value of 3 ft (CF @3 ft) in the left and right eyes, respectively. Riboflavin/ultraviolet A light (UVA) corneal crosslinking (CXL) was conducted on both eyes. Seven months after cross‑linking, LogMAR UDVA was 0.4, the manifest refraction was ‑2.75‑2.50x85 and LogMAR BCVA was 0.1 in the right eye. In the left eye, LogMAR UDVA was CF @3 ft, the manifest refraction was ‑15.00 and LogMAR BCVA was 0.3. The corneal topography was stable 7 months after CXL. Phakic toric ICL was implanted to correct the refractive error, following which the LogMAR UDVA improved to 0.1 in the right eye and 0.3 in left eye, and visual acuity remained stable for 6 months after ICL implantation. In conclusion, combining riboflavin/UVA corneal cross‑linking and phakic toric ICL implantation may be an alternative in the correction of high refractive error in patients with keratectasia.
