Abstract

Purpose : To compare distance and near visual acuity, stereopsis, accommodative function, and higher-order wavefront aberrations in eyes wearing multifocal center-distance, dual-focus, and single-vision soft contact lenses.

Methods : 34 right eyes with a mean SER of -3.58 (SD ±1.68) and 34 left eyes with a mean SER of -3.45 (SD ±1.80) of healthy participants with a mean age of 21.86 years (SD ±2.14) were evaluated.
Non-cycloplegic measurements were conducted without contact lenses and while subjects wore multifocal center-distance (ArtMost SoftOK and SEED Pure UP), dual-focus (CooperVision MiSight), and single-vision soft contact lenses (iLens Aqua).
RM one-way ANOVA with Bonferroni post-hoc analysis and chi-square analysis were used for data analysis. A value of P < 0.05 was considered statistically significant.

Results : The mean baseline distance visual acuity was -0.04 logMAR ± 0.05. No statistically significant difference was found. (F = .321, P = .864).
The mean baseline near visual acuity was 0.00 logMAR ± .06. No statistically significant difference was found. (F = 1.175, P = .321).
The mean baseline stereopsis was 43.7 arcsec ± 6.6. No statistically significant difference was found. (χ2 = 1.718, P = .787)
The mean baseline accommodative amplitude was 10.67 D ± 1.53. A statistically significant difference was found. (F = 2.562, P = .040) The MiSight lens showed a significant decrease to 8.88 D ± 2.34 (P = .047).
The mean baseline accommodative response was 0.53 D ± 0.48. No statistically significant difference was found. (χ2 = 1.718, P = .787)
The mean baseline spherical aberration was +.00404 µm ± 0.0551. A statistically significant difference was found. (F = 51.672, P < .001). The SoftOK lens showed a significant increase to +0.2497 µm ± 0.0775. (P < .001)
The mean baseline horizontal coma was -0.0158 µm ± .0434. No statistically significant difference was found. (F = .818, P = .515)

Conclusions : Distance and near visual acuity, stereopsis, accommodative response, and horizontal coma with multifocal center-distance, dual-focus, and single-vision soft contact lenses, were comparable to baseline values. The accommodative amplitude decreased statistically significantly when wearing the MiSight contact lens. Positive spherical aberration increased statistically significantly with the SoftOK contact lens. The clinical significance of these differences needs to be investigated further.
