As of Sept. 2013, the study had enrolled its target population of 2,000 patients wearing spectacles or contact lenses. Responses to a follow-up survey at 1 year were available from 460 subjects who stayed in contact lenses, 579 patients who went from wearing contact lenses to have LASIK, and 199 patients who wore glasses at entry and then had LASIK.
The 1-year data showed that among patients who went on to LASIK and those who stayed in contact lenses, nearly all (96% to 98%) would recommend their current vision correction method to a family member or friend. However, the proportion of patients who would strongly recommend their current method of vision correction was much higher among patients who went from glasses or contact lenses to LASIK (77% and 87%, respectively) compared to those who stayed with their contact lenses (53%).
Reinforcing patient satisfaction with LASIK were data showing that 96% of former contact lenses wearers who had LASIK answered affirmatively to the question, “At this time, do you believe LASIK works better for you than wearing contact lenses?”
The study also found that LASIK had a benefit of reducing night-driving difficulties whether patients were previously in glasses or in contact lenses. At baseline, about 60% of patients said they experienced at least a little difficulty driving at night because of vision within all three study groups (glasses to LASIK, contact lenses to LASIK, or continued contact lens wear). After 1 year, the proportion of patients having any vision-related night-driving difficulty was reduced to 46% among patients who had gone from glasses to LASIK, and to 38% in those who had switched from contacts to LASIK, but it was relatively unchanged among patients who stayed in contacts.
