Scleral contact lenses have a range of therapeutic and optical applications. In recent years,
scleral lens prescribing has increased due to significant advances in ocular imaging
technology, lens manufacturing processes, and the widespread availability of scleral lenses
globally. While the optical principles of scleral lenses are identical to those of corneal rigid
lenses (ie the post-lens tear layer neutralises the majority of anterior corneal astigmatism
and higher order aberrations), the nature of scleral lenses and their typical fitting …
