Correcting keratoconus with intracorneal rings

J Colin et al. J Cataract Refract Surg. 2000 Aug.

Abstract

Purpose: To evaluate the potential of intrastromal corneal ring technology (Intacs, KeraVision) to correct keratoconus without central corneal scarring.

Setting: Department of Ophthalmology, Brest University Hospital, Brest, France.

Methods: In this prospective, noncomparative, interventional case series, Intacs segments were implanted in 10 keratoconic eyes with clear central corneas and contact lens intolerance after corneal pachymetry was checked. Segment thicknesses varied based on corneal topography analysis.

Results: No intraoperative complications occurred. The mean follow-up was 10.6 months. Postoperative results revealed a reduction in astigmatism and spherical correction and an increase in topographical regularity and increased uncorrected visual acuity.

Conclusion: Intacs technology can reduce the corneal steepening and astigmatism associated with keratoconus.
