Effects of peripheral defocus soft lenses on the accommodative function of high myopia children
Objective To investigate the changes in accommodative function after one year of wearing peripheral defocus soft lenses in high myopia children.Methods 27 cases of high myopia children(54 eyes)who underwent myopia correction with peripheral defocus soft contact lenses were incorporated as the observation group.27 cases(54 eyes)of single-focus frame glasses wearers matched with age,gender,and refractive status were selected as the control group during the same period.The changes in monocular ac-commodation amplitude,positive/negative relative accommodation,accommodation lag,monocular accommodation sensitivity,and binocu-lar accommodation sensitivity were observed in two groups of patients after different correction methods for one year were analyzed.Results The monocular accommodation amplitude,positive relative accommodation,monocular and binocular accommodation sensitivity of the observation group increased in comparison to the control group while the accommodation lag decreased(P<0.05).There was no statistical difference in negative relative accommodation between the observation group and the control group(P>0.05).Conclusion In high myopic children,wearing peripheral defocus soft lenses can improve accommodation function and it can be used as one of the effective ways to delay the progression of high myopia.
