Abstract
Objective: The primary objective of this study was to quantify the visual improvement
and the reduction of corneal curvature achieved through association of Mini
Asymmetric Radial Keratotomy (MARK) and Corneal Collagen Cross-linking (CXL).
Design: Retrospective clinical trial.
Methods: Sixteen eyes (sixteen patients) were included. Computerized corneal
topography and Scheimpflug camera equipment were used to measure higher order
corneal aberrations before treatment and during follow-up. Outcome parameters,
including uncorrected visual acuity and best corrected visual acuity, have been
measured as well. Examinations were performed at 3, 6, 12 and 24 months following
both MARK and CXL.
Results: A sharp reduction of both corneal curvature and corneal aberrations was
observed after MARK surgery, followed by a smaller improvement following CXL
treatment.
Conclusion: The combination of MARK with CXL offers a significant improvement of
visual acuity and a reduction of corneal curvature along with the corneal reinforcement
provided by CXL.
