The impact of orthokeratology lens wear on binocular vision and accommodation: A short-term prospective study

摘要: Abstract Purpose To investigate the effects of short-term orthokeratology (OK) on accommodation and binocular visual function in young adults. Methods Twenty-four myopes (18 to 38 years) were fitted with OK lenses both eyes. Best corrected distance acuity (VA), subjective objective refractions, corneal topography a series vision tests measured at baseline (BL) before lens wear then repeated after 28 nights OK. Data from 15 subjects who demonstrated successful fit are reported. Results Corneal flattening hyperopic shifts spherical equivalent refractive error (all p  Conclusions Binocular remained unchanged OK, although variability phoria stereoacuity measures reduced. This suggests that improves or maintains accommodative adult achieve good Myopes phorias outside normal ranges and/or poor facility may benefit most function.
