Read moreIntroduction Traditionally, gas permeable, scleral and even hybrid contact lenses are recommended for patients with keratoconus or other diseases that cause irregularity of the cornea, as they can effectively correct the significant levels of astigmatism through neutralization by the tear film. However, there is evidence to support the use...
Read moreBackground Post-surgical ectasia is a complication in which a cornea that has undergone a refractive surgical procedure becomes progressively irregular and thinned leading to protrusion and undesirable visual disturbances such as blur and higher order aberrations. When screening a candidate for LASIK, many factors must be considered to reduce...
Read moreIntroduction The vast majority of the lenses we fit in contact lens practice are soft lenses. The amount of attention that goes into ‘fitting’ soft lenses is limited in contrast to the focus on scleral lens fitting, corneal lens fitting, and orthokeratology, for instance.
