Contact lenses for children

Chapter 119 Contact lenses for children

Parents are the key to successfully fitting children with contact lenses. Explain the reasons why a particular lens type is chosen as well as the risks and advantages of lens wear. With the available range of lenses it is rare to find a case that cannot safely be fitted, but the tolerance of the child or the visual limitations of the parent may make it preferable to avoid or postpone lens wear.

High prescriptions and aphakia

Contact lenses provide a clearer field of vision than spectacles.2 High myopes have better visual acuity with contact lenses than with spectacles, which reduce the image size. However, high hypermetropes and aphakes have better acuity in spectacles because the image size is larger.2 This can lead to disappointment when aphakes with poor acuity are fitted with contact lenses.

Unilateral ametropia

Contact lenses reduce aniseikonia for both unilateral axial and refractive myopia,3 but amblyopia is usually present and highly myopic eyes (over –9.00 D) do not usually respond well to patching;4 only 32% of unilateral aphakes achieve vision greater than 0.6 logMAR5 and, because binocularity is rare, children do not notice much difference when wearing a lens, making compliance poor. However, wearing a contact lens often reduces the angle of any strabismus.


Congenital cataracts

The number of young aphakes requiring contact lenses has decreased in recent years as more infants have intraocular lenses (IOLs) inserted. Many of them are likely to have microphthalmos or other anomalies. Pseudophakes also frequently need to be corrected with contact lenses.
