“…3 The improvement we found in the dependence on correction subscale is an interesting result that was first reported by Ritchey et al in a study that randomized patients to wear either CRT lenses or Focus Night and Day lenses (CIBA Vision, Duluth, GA) on a 30-day continuous-wear basis. 7 In their study, the eight patients in the CRT arm showed a significant improvement in the dependence on correction subscale after 3 months of wearing CRT lenses when compared with their previous mode of correction. This finding suggests that although patients must wear their CRT lenses while asleep to maintain their treatment effect, they may not feel as dependent on their correction because they do not have to wear them while doing their day-to-day activities.…”

“…3,4 To our knowledge, there have only been two studies published using the NEI-RQL-42 to evaluate the effect of overnight contact lens corneal reshaping on refractive error-specific quality of life. [5][6][7] In modern overnight orthokeratology, a temporary reduction of myopia is achieved by reshaping the cornea using a reverse geometry rigid gas-permeable (RGP) contact lens. Corneal refractive therapy (CRT; Paragon Vision Sciences, Mesa, AZ) was the first contact lens procedure approved by the U.S. Food and Drug Administration for overnight contact lens corneal reshaping.…”

CRT may improve a patient's perception of their visual independence, decrease the amount of ocular symptoms they report, and increase symptoms of glare. A larger, well-controlled clinical trial is necessary to verify these results. An increase in patient-reported glare is likely the result of measured increases in higher-order aberrations after CRT, especially spherical aberration under mesopic and scotopic conditions.

“…About 90 per cent of the interviewed patients ranked the treatment as good or very good. Previous surveys using the National Eye Institute Refractive Error Quality of Life (NEI‐RQL 42) instrument to evaluate the levels of patient satisfaction with overnight ortho‐k showed that there were either no differences 31 or better 25 quality‐of‐life indices in overnight ortho‐k compared to 30‐day continuous wear silicone hydrogel lenses or daily disposable hydrogel lenses, respectively. This indicates that overnight ortho‐k is well accepted as a means for myopic correction.…”

Purposes:The aim of this study was to analyse clinical data of children undergoing orthokeratology (ortho-k) and to investigate patients'/parents' perspective on ortho-k via telephone interviews. Methods: Clinical records of children undergoing ortho-k from a university optometry clinic were reviewed and the effects of ortho-k on refraction, vision and cornea were investigated. A telephone interview was conducted to solicit patients'/parents' perspective of the treatment. Results: One hundred and eight files were reviewed. Median age of the children was nine years (range six to 15); mean (ϮSD) pre-treatment refractive sphere was -3.56 Ϯ 1.49 D and the median refractive cylinder was -0.50 D (range zero to -4.25 D). Significant refractive spherical reduction (58 per cent), improvement in unaided vision and corneal topographical changes were noted after only one night of wear. No significant change in astigmatism was found. Corneal staining was the most commonly observed complication with ortho-k and more than 80 per cent of patients were advised to apply ocular lubricants to loosen the lens before lens removal. Ortho-k was mainly undertaken for myopic control and about 90 per cent of the respondents reported good/very good unaided vision after ortho-k and ranked the treatment as satisfactory or very good. Lens binding and ocular discharge were the most frequently reported problems during the treatment. Conclusion: Under close monitoring, overnight ortho-k is effective and safe for reducing low to moderate myopia and the treatment is well accepted by the children.

“…The NEI-RQL-42 is a disease-specific VRQoL instrument that was designed specifically to assess the impact of refractive error and its correction on vision-related functioning. The NEI-RQL-42 has been shown to distinguish between patients with different types of refractive error and with varying forms of refractive correction [1,2], and it was also reported to be responsive to changes in VRQoL resulting from keratorefractive surgery [3][4][5][6], correction of astigmatism and presbyopia with contact lenses [7,8] and orthokeratology [9][10][11].…”
