Phakic Toric Implantable Collamer Lens Implantation for the Correction of High Myopic Astigmatism in Eyes With Keratoconus

Kazutaka Kamiya, MD, PhD; Kimiya Shimizu, MD, PhD; Wakako Ando, COT; Tadatoshi Fujisawa, MD, PhD; Yoshimori Asato, MD, PhD

Abstract

PURPOSE

To present two patients in whom phakic toric Implantable Collamer Lenses (toric ICL, STAAR Surgical) have been effective for the correction of high myopic astigmatism with stable keratoconus.

METHODS

Both patients had a history of contact lens intolerance, and refraction and corneal topography were stable for 3 to 4 years. Preoperatively, the manifest refraction was –10.00 –6.00 x 100 in case 1 and –8.00 –2.75 x 100 in case 2.

RESULTS

Postoperatively, the manifest refraction was +0.50 –1.00 x 90 in case 1 and –0.25 –1.25 x 100 in case 2. Uncorrected visual acuity and best spectacle-corrected visual acuity were markedly improved after implantation in both patients. No progressive sign of keratoconus was seen during 1-year follow-up.

CONCLUSIONS

Phakic toric ICL implantation may be an alternative for the correction of high myopic astigmatism in eyes with stable keratoconus. [J Refract Surg. 2008;24:840-842.]
