Abstract: Purpose To evaluate effects and related factors of short-time accommodation training on measuring consistency of InnovEyes Sitemap (Alcon/WaveLight; Alcon Laboratories, Inc), NIDEK ARK-1 autorefractor (Nidek Corporation), and subjective refraction (SR). Methods One hundred adults (100 eyes) with myopia aged 17 to 40 years were enrolled. Refraction was obtained by InnovEyes Sitemap, autorefraction, and SR in a randomized order. Refractive data of InnovEyes Sitemap were grouped into two groups without and with application of a 2.00 diopter (D) flipper before InnovEyes Sitemap. Results The average difference in spherical equivalent (SE) between InnovEyes Sitemap and SR (autorefraction) decreased from −0.56 ± −0.41 D in the without accommodation training group to −0.29 ± −0.14 D in the with accommodation training group, with 95% CI of limits of agreement (LOA) shrinking dramatically (InnovEyes Sitemap–SR: −1.39 to 0.27 vs −0.71 to 0.14 D; InnovEyes Sitemap–autorefraction: −1.23 to 0.40 vs −0.69 to 0.40 D). Furthermore, short-time accommodation training significantly improved the consistency of myopia measurements, with the proportion of SE differences within 0.50 D between InnovEyes Sitemap and SR significantly increasing from 56% to 88% ( P < .001). Meanwhile, J0 and J45 showed no significant difference ( P > .05) with similar LOA among three techniques in both groups. SE difference of InnovEyes Sitemap (with accommodation training group minus without accommodation training group) was significantly correlated to SE difference between SR and habitual glass refraction (β = −0.312, P = .001), lens thickness (β = 0.262, P = .006), and axial length (β = 0.199, P = .037). Conclusions Short-time accommodation training could promote spherical consistency but not deteriorate cylindrical agreement among InnovEyes Sitemap, autorefraction, and SR, and this effect showed more effective in eyes with more undercorrected myopia in habitual prescription, thicker lens, and longer axial length.
