“…In addition to analyzing the entire sample of 30 participants, a subcohort was established to include only participants who achieved high-contrast logMAR acuity of +0.30 (20/40 Snellen equivalent) or better in each eye with both lens treatments. This is a commonly used cutoff to measure visual acuity success in orthokeratology 22 and refractive surgery. 23 The good vision subcohort allows for comparisons to be made with our published aberration outcomes 12 and is indicative of what would happen in a clinical setting, given that practitioners would often re-fit lenses if the vision was not satisfactory.…”

Purpose There has been little research on myopia management options for patients with astigmatism. This study quantified changes in peripheral refraction induced by toric orthokeratology (TOK) and soft toric multifocal (STM) contact lenses. Methods Thirty adults with refractive error of plano to −5.00 D (sphere) and −1.25 to −3.50 D (cylinder) were enrolled. Cycloplegic autorefraction was measured centrally, ±20 degrees, and ±30 degrees from the line of sight nasally (N) and temporally (T) on the retina. Measurements were made at baseline, after 10 ± 2 days of TOK wear (without lenses on eye), and after 10 ± 2 days of STM wear (with lenses on the eyes) and compared with repeated-measures analysis of variance. Results Compared to baseline, TOK induced a myopic shift in defocus (M) at all locations (all P < 0.01), but STM only induced a myopic shift at 20 T in both eyes and 30 N/T in the left eye (all P < 0.01). TOK resulted in more myopic defocus than STM at all locations (all P < 0.05) except 20 T in the left eye. TOK induced more J 0 astigmatism at all locations (all P < 0.02), except 20 N in the right eye; J 0 with STM was different than baseline at 20 N in both eyes and 30 N in the right eye (all P < 0.02). TOK induced more J 0 astigmatism than STM at all locations (all P < 0.01), except 20 T in the left eye. Differences in J 45 astigmatism, when significant, were clinically small. Conclusions Greater amounts of peripheral myopic defocus and J 0 astigmatism were induced by TOK compared to STM, which may influence efficacy for myopia management.

Purpose: Spherical orthokeratology and soft multifocal contact lenses are commonly used for myopia control and correction, but have been shown to increase spherical aberration, coma and total higher order root mean square (HORMS) aberrations. There are limited myopia control contact lens options for patients with moderate to high astigmatism. The purpose of this study was to quantify changes in higher order aberrations (HOA) in myopic astigmatic eyes fitted with toric orthokeratology (TOK) and soft toric multifocal (STM) contact lenses. Methods: Ocular wavefront aberrations were measured in both eyes of 30 adult subjects and are reported through the 6th radial order over a 5 mm, dilated pupil. All eyes met refractive criteria of myopia (À5.00 D to plano) and cylinder (À3.50 to À1.25 D). Three measurements were taken at baseline and after 10 AE 2 days of lens wear (TOK, STM). Sixteen subjects achieved logMAR high contrast visual acuity of 0.30 or better in both eyes and were included in this analysis. Repeated measures analysis of variance and post-hoc paired t-tests were used, as appropriate, with Benjamini-Hochberg correction. Results: Higher order root mean square, spherical aberration (C12), and coma RMS (C7, C8) increased with TOK (0.641 [0.222], 0.409 [0.157], 0.426 [0.187] µm, respectively) and STM (0.481 [0.107], 0.223 [0.139], 0.320 [0.130] µm, respectively) from baseline (all p < 0.001). TOK was elevated compared to STM for HORMS (p = 0.03), spherical aberration (p = 0.001) and coma RMS (p = 0.04). Conclusions: Toric orthokeratology induced more HORMS, spherical aberration and coma RMS than STM in myopic astigmats; however, both lens types showed an increase in HOA compared to baseline, which placed patients outside the age and pupil size matched normative ranges. While the optical changes that accompany these modalities are helpful for myopia management, the induction of HOAs may have unintended consequences on visual performance.

Success Rate of Incorporating Corneal Refractive Therapy into 3 Different Ophthalmology Practices

Abstract: Orthokeratology is an effective method to correct myopia. Only 1.4% of patients were unresponsive to the correction. There is no difference in the effectiveness of orthokeratology in the right and left eyes, but it does seem to be more effective in women compared with men.
