The Effect Of Two Different Treatment Methods On The Outcome Of Corneal Reshaping.

Introduction: With corneal reshaping gaining popularity, we are exploring two different
fitting techniques to establish the most efficient approach for treating moderate to high
myopia. Methods: We will fit four patients according to manufacturer's guidelines with
corneal reshaping lenses. Of each patient, one eye will be fully corrected at the initial
visit. The other eye will require a two-step approach where the initial lens will correct
half of the refractive error and the two-week follow-up visit will correct the remainder of
the refractive error. The patients presented for six scheduled visits over one month's time.
Results: On the two week follow-up, the overall spherical equivalent of refractive correction in the fully corrected eye was 3.17 (60.03% of full correction). The overall spherical equivalent of refractive correction in the half corrected eye was 3.00 (54.23% of full correction). On the one month follow-up, the overall spherical equivalent of refractive correction in the initially fully corrected eye was 3.13 (59.70% of full correction). The overall spherical equivalent of refractive correction in the initially half corrected eye was 2.87 (50.00% of full correction). Discussion: Treatment zone size, corneal dioptric change and number of lens adjustments showed an overall advantage using the two-step half correction technique, however there was 9. 7% less overall refractive correction compared to the fully corrected technique. Our results showed no clinical advantage to the two step half correction technique.
