Why MiSight 1 day is not a multifocal contact lens


The MiSight® 1 day contact lenses consist of concentric rings with alternating treatment and correction zones. The treatment zones provides +2D of defocus. Does this amount to an ‘add’ in the lenses that may influence accommodation? In this post, BP questions whether MiSight 1 day may influence accommodation or near vision for their patient.

MiSight and near acuity

MiSight 1 day dual focus contact lenses are designed for children with the purpose of myopia control, and not as a 'multifocal' contact lens as fit to presbyopes. How do MiSight 1 day contact lenses work for near vision?

MiSight and near vision

Ruiz-Pomeda et al1 showed that MiSight 1 day contact lenses do not change accommodation or phoria in young wearers when compared to single vision spectacles. Hence, MiSight 1 day should not be considered as similar to a multifocal contact lens, but rather for its specific purpose as a myopia controlling contact lens.

The MiSight 1 day clinical trial showed that near visual acuity was within one letter for MiSight and single vision contact lenses at each annual visit over three years. Distance vision was also similar between MiSight 1 day and single vision, being 6/6 or 20/20 in both presenting and best corrected visual acuity at all visits.2

Fit, adapt and reassess

The priority in this case is to manage myopia progression. If there is concern about accommodation function, the best suggestion is to firstly fit MiSight 1 day, and on review to check acceptance, lens fit and vision, recheck accommodation function and see if any further management is required.

Which treatment to start with?

Although atropine 0.025% and 0.05% appear to slow myopia effectively, atropine typically reduces accommodation amplitude.3 Also consider the fact that the patient needs a myopia correction, as well as myopia control. MiSight 1 day can effectively provide both, as a monotherapy, without any influence on near visual acuity or accommodation.

Take home messages:

  1. MiSight 1 day contact lenses can be expected not to affect near vision or accommodative function, functioning similarly to single vision spectacles or contact lenses at near. Hence they provide effective myopia correction as well as slowing myopia progression in children.
  2. Keep in mind that myopic patients need an effective method to both correct and control their myopia. Optical treatments provide this option.

FDA Indications for use (US only): MiSight® 1 day (omafilcon A) soft (hydrophilic) contact lenses for daily wear are indicated for the correction of myopic ametropia and for slowing the progression of myopia in children with non-diseased eyes, who at the initiation of treatment are 8-12 years of age and have a refraction of -0.75 to -4.00 diopters (spherical equivalent) with ≤0.75 diopters of astigmatism. The lens is to be discarded after each removal.
