Objective To investigate the clinical effect of highly aspherical lenslets(HAL)in myopia control in adolescents.Methods Totally 101 cases(202 eyes)of adolescent myopia patients treated in ophthalmology outpatient department of our hospital from January 2021 to February 2022 were selected as the study objects.Of these,43 cases(86 eyes)wore HAL lenses as an observation group and 58 cases(116 eyes)wore single-vision spectacle lenses(SVL)as a control group.After 12 months of follow-up,the equivalent spherical lens degree and axial length were recorded in 6 months and 12 months respectively.Results The change of equivalent spherical lens in the HAL group was(-0.18±0.22)D and that in the SVL group was(-0.47±0.21)D,and the change in the HAL group was less than that in the SVL group,the difference was significant(P<0.001).The equivalent spherical lens degree in the HAL group was(-0.33±0.32)D and the HAL group was(-0.82±0.20)D at the 12th month,and the change in the HAL group was less than that in the SVL group,the difference was significant(P<0.001).The axial length of the eye in the HAL group was(0.09±0.09)mm and the SVL group was(0.20±0.07)mm in June,and the change in the HAL group was less than that in the SVL group,and the difference was significant(P<0.001).The axial length of the eye in the HAL group was(0.14±0.13)mm and that in the SVL group was(0.37±0.08)mm,and the change in the HAL group was less than that in the SVL group,and the difference was significant(P<0.001).Conclusion Wearing HAL lens for 12 months can effectively slow down the growth of myopia degree and axial length in adolescent myopia patients.
