Abstract

Purpose : To compare accommodative parameters among children corrected over 2 years by single vision spectacles (SV), conventional progressive addition lenses (PALs) and customized PALs.

Methods : 48 myopic children (aged 11.73 ± 1.16 years) with mean of spherical equivalent refraction (SER) of -3.67 ± 0.83D and astigmatism less than 1.50DC were enrolled in the study. They wore different spectacle lenses for two years, 15 corrected by SV (Group I), 17 by conventional PALs with +2.00D addition (Group II), and 18 by customized addition PALs based on Sheard’s criterion (Group III). Continuous accommodative stimulus-response curves (ASRC) were measured on the right eye with full correction by trial lenses. ASRC were obtained by a Grand Seiko WAM-5500 autorefractor in high speed mode at a sampling rate of 5 Hz under continuous stimuli produced by a motorized Badal system, and were fitted with a 3-degree polynomial equation. The slope of ASRC was defined as the steepest slope of the function. Objective accommodative amplitude (AA) was the difference between maximum and the minimum accommodative response. The accommodative lag area between 1D and 6D was calculated by Matlab software.

Results : There were no differences in age among three groups at two-year visit (P>0.05). The slope of ASRC was 0.92±0.08, 0.91±0.08, and 0.92±0.08 for Group I, II, III respectively. The objective AA was 7.08±1.15D, 7.37±1.48D, 7.70±0.88D, and the accommodative lag area was 7.12±0.86D2, 7.19±1.42D2, 7.19±1.42D2 respectively for Group I, II, III. No significant differences were found in the slope (F=0.14, P=0.87), objective AA (F=1.08, P=0.35) and the accommodative lag area (F=0.11, P=0.90) among those three groups at two-year visit.

Conclusions : Neither conventional nor customized addition progressive addition lenses affected the accommodative stimulus-response function in myopic children compared to single vision lenses.
