Purpose
To evaluate the potential of intrastromal corneal ring technology to correct keratoconus without central corneal scarring
Setting
Prospective randomized clinical trial
Methods
ICRS were done first, immediately followed by CXL 3 months later. Outcomes included changes in maximum keratometry (K) and topographic inferior–superior (I–S) difference, maximum flattening of topographic K, and changes in uncorrected (UDVA) and corrected (CDVA) distance visual acuities
Results
The study comprised 98 eyes of 68 patients. Overall, maximum K decreased by an average of 2.5 D, I–S difference improved by 3.9 D, and there was an average maximum flattening of −7.5 D. The UDVA improved by 2.0 logarithm of the minimum angle of resolution lines, on average, and the CDVA improved by 1.1 lines
Conclusions
CXL and ICRS can be used adjunctively with substantial improvement in corneal topography, and with no increase in safety concerns over each procedure alone. Both thicker segment size and single segment placement seem to result in greater topographic improvement
