OBJECTIVE: This study aimed to evaluate the short-term visual performance and subjective satisfaction of a dual-focus soft contact lens (DF-SCL) compared with a single-vision soft contact lens (SV-SCL) in myopic Chinese children over one month of daily wear.
METHODS: Myopic children aged 8 to 14 years first underwent baseline testing with SV-SCL (Proclear), followed by DF-SCL (MiSight). They then continued wearing DF-SCL for one month. Distance and near high-contrast visual acuity (d-HCVA, n-HCVA), contrast sensitivity function, the Subjective Acceptability Questionnaire, and visual performance questionnaire were assessed at four visits: SV-baseline, MiSight (MS)-baseline, MS-1 week, and MS-1 month.
RESULTS: A total of 38 subjects (19 female, 19 male; mean age 10.75±1.13 years; mean spherical equivalent refraction, -1.81±0.69 D) completed the study. At baseline, d-HCVA was significantly better with SV-SCL (-0.05±0.06 logMAR) than with DF-SCL (-0.02±0.04 logMAR, P =0.03), while n-HCVA showed no significant difference ( P =0.27) between with SV-SCL (-0.03±0.05 logMAR) and DF-SCL (-0.01±0.04 logMAR). After one week of DF-SCL wear, n-HCVA improved significantly (-0.04±0.06 logMAR, P =0.04) compared with MS-baseline. After one month of DF-SCL wear, d-HCVA (-0.03±0.06 logMAR, P =0.55) and n-HCVA (-0.05±0.07 logMAR, P =0.48) were comparable with SV-baseline. The contrast sensitivity with DF-SCL improved at 12 and 18cpd after one week of DF-SCL wear compared with MS-baseline. In the questionnaire, overall satisfaction significantly improved at the 1-month visit ( P <0.001) compared with MS-baseline, and visual symptoms of paracentral and peripheral blurry vision alleviated after a week of wearing ( P =0.009).
CONCLUSION: Myopic Chinese children demonstrated good visual quality and high subjective satisfaction over one month of DF-SCL wear, despite a slight initial decline in visual performance compared with SV-SCL.
