Abstract
The presence of small (15-50 μm), irregular-shaped microcysts
with defined borders in the corneal epithelial layer indicates
chronic corneal hypoxia during extended contact lens wear,1
but may also be observed in non-contact lens wearers with less
severity.2 They usually cause mild or no visual impairment.
Orthokeratology lenses reshape the corneal surface overnight
as a result of mechanical and fluid forces. While mild
microcysts have been reported in adult orthokeratology
wearers,3 they have not been observed in orthokeratology
studies on children, spanning 2–5 years.4–6
Presented here is a case of corneal oedema associated with
over-wear of decentred orthokeratology lenses in a child being
kept at home during the novel coronavirus (COVID-19)
pandemic.
