Correcting keratoconus with intracorneal rings

Purpose: To evaluate the potential of intrastromal corneal ring technology (intacs(TM), KeraVision) to correct keratoconus without central corneal sca rring. Setting: Department of Ophthalmology, Brest University Hospital, Brest, Fra nce. Methods: In this prospective, noncomparative, interventional case series, I ntacs segments were implanted in 10 keratoconic eyes with clear central cor neas and contact lens intolerance after corneal pachymetry was checked. Seg ment thicknesses varied based on corneal topography analysis. Results: No intraoperative complications occurred. The mean follow-up was 1 0.6 months. Postoperative results revealed a reduction in astigmatism and s pherical correction and an increase in topographical regularity and increas ed uncorrected visual acuity. Conclusion: Intacs technology can reduce the corneal steepening and astigma tism associated with keratoconus. J Cataract Refract Surg 2000; 26:1117-112 2 (C) 2000 ASCRS and ESCRS.
