Established soft contact lens wearers' awareness of and initial experiences with orthokeratology

To understand the initial awareness of and experience with orthokeratology in a group of adult, symptomatic, soft contact lens (CL) wearers.

This was a prospective, 3-month, open-label study of symptomatic soft CL wearers who were between the ages of 18 and 45 years. Baseline measurements were taken and then all subjects were treated with orthokeratology. A dry eye evaluation was completed at baseline prior to orthokeratology treatment. This same dry eye evaluation was completed 1 week and 1 month after orthokeratology treatment. An investigator-designed questionnaire that aimed to understand the subject's initial awareness of and experience with orthokeratology was also administered at the baseline, 1-week, 1-month and 3-month visits (perceptions, knowledge, tolerance and ability to apply and remove orthokeratology lenses).

Twenty-nine out of 40 subjects completed this study. Completed subjects (age = 24.28 ± 3.75 years) had significant improvements in ocular comfort over the course of the study compared to their soft CLs. Most subjects were unfamiliar with orthokeratology before the study, were able to quickly adapt to the treatment and were likely to recommend orthokeratology to friends or children for myopia management.

This study found that few subjects knew about orthokeratology before learning about it through this investigation, suggesting that patients should be offered this treatment more regularly. This conclusion is supported by the ability of the subjects to learn and adapt to orthokeratology with ease, and their likelihood to recommend it to a friend or child.
