Myopia Control With Orthokeratology Contact Lenses in Spain: A Comparison of Vision-Related Quality-of-Life Measures Between Orthokeratology Contact Lenses and Single-Vision Spectacles

The aim of this Spanish study was to compare vision-related quality-of-life of overnight orthokeratology contact lenses for children  with glasses . Thirty-one children were fitted with orthokeratology contact lenses, 30 with spectacles. Children wearing orthokeratology contact lenses rated overall vision, distance vision, symptoms, appearance, satisfaction, activities, academic performance, handling, peer perceptions, and the overall score significantly better compared to children wearing spectacles. Near vision and handling were, respectively, rated better and similar. This study provides further evidence that overnight contact lenses are an excellent option for children in terms of quaility of life, along other studies that confirm their safety and ability to slow down or halt the increase of myopia. 

Abstract
Purpose: To compare vision-related quality-of-life measures between children wearing orthokeratology (OK) contact lenses and distance single-vision (SV) spectacles.

Methods: Subjects 6 to 12 years of age and with myopia of -0.75 to -4.00 diopters and astigmatism less than or equal to 1.00 diopters were prospectively assigned OK contact lens or SV spectacle correction. A pediatric refractive error profile questionnaire was administered at 12- and 24-month intervals to evaluate children's perceptions in terms of overall vision, near vision, far distance vision, symptoms, appearance, satisfaction, activities, academic performance, handling, and peer perceptions. The mean score of all items was calculated as the overall score. Additionally, parents/guardians were asked to rate their child's mode of visual correction and their intention to continue treatment after study completion.

Results: Thirty-one children were fitted with OK contact lenses and 30 with SV spectacles. Children wearing OK contact lenses rated overall vision, far distance vision, symptoms, appearance, satisfaction, activities, academic performance, handling, peer perceptions, and the overall score significantly better than children wearing SV spectacles (all P<0.05). Near vision and handling were, respectively, rated better (P<0.001) and similar (P=0.44) for SV spectacles in comparison to OK contact lenses. No significant differences were found between 12 and 24 months for any of the subjective ratings assessed (all P>0.05). Parents/guardians of children wearing OK contact lenses rated visual correction method and intention to continue treatment higher than parents of children wearing SV spectacles (P≤0.01).

Conclusion: The results indicate that the significant improvement in vision-related quality of life and acceptability with OK contact lenses is an incentive to engage in its use for the control of myopia in children.
