The Relationship between Axis Length Difference and Refractive Error in Unilateral Myopic Anisometropic Children Treated with Orthokeratology
Table 1
Inclusion criteria.
(1) The age was between 8 and 15 years at baseline
(2) Refractive error (spherical equivalent refraction) ranged from −4.25 D to −0.75 D in the myopic eye and between −0.5 D and +1.5 D in the fellow eye
(3) Best-corrected visual acuity was 20/20 or better in the myopic eye and the uncorrected visual acuity was 20/20 or better in the fellow eye (no correction was needed)
(4) Corneal power ranged from 40.00 D to 46.25 D and astigmatism was no less than −1.50 D
(5) There was no history of orthokeratology or use of other contact lenses or spectacles
(6) There were no serious eye diseases, such as congenital cataract, glaucoma, and strabismus and no active inflammatory ocular surface diseases
(7) There were no contraindications for overnight Ortho-K lens wear
Exclusion criteria were (1) SERE of the nonmyopic eye <−0.5 D or (2) uncorrected visual acuity of the nonmyopic eye ever dropped below 20/20 for any reason.
