Such study was done by comparing 15 eyes that do not have any contact lenses on to 12 eyes that were fitted with contact lenses for one to ten weeks right after surgery. The outcome has resulted to the change of baseline in the best corrected visual acuity, refractive sphere and cylinder, keratometry and astigmatism values, as well as inferior-superior (I-S) value on EyeSys and a maximal keratometry value on the Pentacam (Oculus). Such measurements were done right before the surgery took place and was done at three 6-month intervals right after the surgery.
The Result of the Study on Cross-linking the rigid gas permeable contact lenses
There were no significant changes to the study parameters all throughout the duration of follow-ups on the group that did not receive the rigid gas permeable contact lenses. However, on the other group that received the contact lenses right after surgery, a considerable improvement were observed at follow-up intervals for I-S values and maximal keratometry values, at 6 and 12 months for refractive power steep as well as simulated astigmatism values, and at 12 months for the refractive power flat values.
The author of the study admitted that the observation was done in only a small series of patients. However, the group believed that they have succeeded in giving a more balanced view when it comes to the efficacy of the current cross-linking technique, while documenting the influence of fitting contact lenses right after cross-linking on topographic outcome parameters.
