Phakic toric Implantable Collamer Lens implantation for the correction of high myopic astigmatism in eyes with keratoconus

J Refract Surg. 2008 Oct;24(8):840-2. doi: 10.3928/1081597X-20081001-12.

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.
