Clinical Efficacy of MiSight 1 day Soft Contact Lenses in Korean Myopic Children.

Objectives: This study aimed to investigate the clinical efficacy of MiSight 1 day soft contact lenses (MiSight CL) in Korean children with mild-to-moderate myopia. In addition, the study compared the effects of MiSight CL in children who had or had not previously used orthokeratology contact lenses (Ortho-K).

Methods: A total of 66 children aged 5 to 16 years, who were prescribed MiSight CL, were included in the study. Based on a myopia degree of -4 diopters (D), children were divided into mild and severe myopia groups to compare the effectiveness of myopia suppression. In addition, 55 eyes previously using Ortho-K were compared with 76 eyes using MiSight CL for the first time.

Results: The average follow-up period was 6.58±3.74 months. The average refractive value before using MiSight CL was 3.64±1.56 D, and there was no significant change in the final visit. Comparing myopia suppression between different degrees of myopia and previous use of Ortho-K lenses, there was no significant change in refractive error before and after using MiSight CL (unpaired t test, P >0.05). The main reason for Ortho-K failure was low visual acuity after correction. Regardless of Ortho-K history, children showed good visual acuity after wearing MiSight CL, and no other side effects were observed.

Conclusions: MiSight CL effectively inhibited the progression of myopia in Korean children with mild-to-moderate myopia. MiSight CL offer the advantage of easy application, making them a viable alternative when Ortho-K are not suitable.
