Abstract
Purpose :
To better understand the visual experience and ocular symptoms that influence eye preference in individuals that received wavefront-guided (WFG) LASIK and wavefront-optimized (WFO) LASIK treatments in a fellow eye controlled randomized study.
Methods :
A prospective randomized controlled clinical trial (NCT02565537) was conducted where 102 myopic individuals were randomly assigned to receive WFO-LASIK in one eye and WFG-LASIK in the contralateral eye. At the pre-operative visit and subsequent post-operative visits, individuals were asked to identify eye preference. The survey responses of individuals who preferred WFG-LASIK were compared with those who did not preferred WFG-LASIK. The same was done for responses to WFO-LASIK treatments.
Results :
At POM#12, 45% of subjects did not have an eye preference, 33% preferred WFO-LASIK treated eye, and 22% preferred WFG-LASIK treated eye (p=0.2). For individuals who did not prefer the WFG-LASIK eye, they noted significantly worse “hazy vision” and “blurry vision” compared with those who preferred the WFG-LASIK treatment (p<0.05). No differences in visual experience or ocular symptoms were reported by individuals who did prefer or did not prefer WFO-LASIK treatment.
Conclusions :
At 12 months post WFG-LASIK treatment in one eye and WFO-LASIK treatment in the contralateral eye, most individuals did not have eye preference. Individuals who did not prefer WFG-LASIK noted hazy and blurry vision compared with individuals who preferred the WFG-LASIK treatment.
