Correcting keratoconus with intracorneal rings.
OBJECTIVE
To evaluate the potential of intrastromal corneal ring technology (Intacs, KeraVision) to correct keratoconus without central corneal scarring.


METHODS
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.


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