Abstract
Abstract• AlM: To observe the changes of visual acuity and contrast sensitivity function in teenagers with different diopters after wearing overnight orthokeratology in order to understand the effects on visual quality.•METHODS:A self-controlled study was used. Eighty four young myopic subjects (156 eyes) aged 12. 60 ± 2. 03 years in which there were forty males and forty-four females with spherical equivalent(SE) -3. 65±0. 79D were recruited in the study from March 1st 2013 to May 30th 2015. Based on diopters, the subjects were divided into group A (-0. 75~-2. 00D), group B(-2. 25~-4. 00D) and group C (-4. 25 ~ -6. 00D). All the lenses were worn every night over 8 hours. Uncorrected visual acuity ( UCVA ) , subjective refraction,best corrected visual acuity(BCVA), contrast sensitivity function were examined before, 1, 6, 12mo after the initiation of orthokeratology. The database was analyzed by SPSS17. 0 using one-way ANOVA.•RESULT:1 ) Comparison between risual acuity and SE:The UCVA improved significantly and SE decreased after wearing orthokeratology lens 1, 6, 12mo in 3 groups, showing significant decline in comparison with that before orthokeratology ( P < 0. 05 ). There was no significant change among 1,6,12mo after wearing orthokeratology( P>0. 05). There was no significant change in BCVA (P>0. 05). 2 ) Comparison on contrast sensitivity function:Contrast sensitivity function at all spatial frequencies in 3 groups 1, 6, 12mo after wearing lenses compared with those before wearing: There was no change before and after wearing at the low spatial frequency(3c/d) and the high spatial frequency (18c/d), but slight increases in group A and group B in the spatial frequency(6c/d, 12c/d) after wearing lenses. There were slight decreases in group C at all spatial frequencies after wearing. But there was no statistical significance between before and after wearing in all three groups(P>0. 05).•CONCLUSlON:Overnight orthokeratology can improve UCVA and has no obvious effect on the overall visual quality. lt deserves to be applied and spreaded in clinical practice.关键词
