The Impact of Overnight Orthokeratology on Accommodative Response in Myopic Subjects.

摘要: This study aimed to evaluate the effects of two months orthokeratology (OK) treatment in accommodative response young adult myopes. Twenty eyes (21.8 ± 1.8 years) were fitted with Paragon CRT® 100 LENS treat myopia between -1.00 and -2.00 D. Low- high-contrast visual acuity (LCDVA HCDVA), central objective refraction, light disturbance (LD), (using Grand Seiko WAM-5500 open-field autorefractometer coupled a Badal system) measured at baseline (BL) before lens wear after 1, 15, 30, 60 nights OK. Refractive error correction was achieved during first fifty days OK wear, minimal changes afterwards. LD analysis showed transient increase followed by reduction levels over 30 treatment. The lower than expected for all target vergences visits (BL: 0.61 D 1.00 0.96 5.00 D; N: 0.36 0.79 D). On average, lag decreases time wear. However, these differences not statistically significant (p > 0.050, repeated-measures ANOVA Friedman test). shows that overnight does affect objectively young, low myopic stabilization.
