Evaluation of Subjective Satisfaction with Orthokeratology: A Pilot Study

Abstract

Background: This study evaluates subjective satisfaction levels among Singapore-based OK lens wearers and investigates what motivated them to go for OK.
 Methods: A customised survey form was administered. Participants’ perceptions were assessed along the dimensions of vision, facial appearance, satisfaction, activity, and symptoms. The participants also had to indicate what motivated them to go for OK. The remaining questions focussed on the participants’ demographics and OK related routines since the survey was designed to be a stand-alone questionnaire that is suitable for a specialised optometry setting.
 Results: OK participants (n=100) demonstrated an overall positive experience across vision, facial appearance, satisfaction, and activity dimensions. Most participants either did not experience or only occasionally experienced the surveyed symptoms. Seeing clear throughout the day (71%), myopia control (70%), and convenience for school/occupation (65%) and sports (59%) were the most popular reasons why participants were on OK. Better appearance (36%), and discomfort with spectacles (34%) and contact lenses (11%) were the other motivating factors.
 Conclusion: Orthokeratology is associated with high levels of satisfaction rate. Seeing clear throughout the day, myopia control and convenience for day-to-day activities are the key reasons why participants are on OK treatment. Optometrists, while ensuring rigorous compliance to lens care regimen and good adherence to routine follow-ups, may positively recommend orthokeratology not just for children for the purpose of myopia control but to potentially anyone, who wants to be free of day-time myopic refractive correction.
