“…Regarding the variation in corneal thickness while wearing contact lenses, it is highly important to mention that measuring corneal thickness with a contact lens using OCT leads to a wrong result, due to the appearance of distortions as a result of the difference between the refractive indexes of the contact lens and the cornea [39,40]. This is the reason why we chose differences of corneal thickness as our data to analyze, since when two corneal thickness (measured with the same contact lens) values are subtracted, the distortion does not play any role.…”

“…Keratometry‐derived central corneal curvature values do not necessarily correlate well with the best fitting BOZR for a soft lens; rather, the topography of the corneo‐scleral junction can strongly influence the fitting . Anterior segment OCT has been used to evaluate the influence of the soft lens mid‐peripheral shape profile and edge design on apparent epithelial thickness and indentation of the ocular surface with lens movement . OCT can also be used to analyse the shape of the scleral curvature, which may be of assistance for guiding peripheral scleral lens design …”

Contact lenses are the primary form of visual correction for patients with keratoconus. Contemporary advances in contact lens designs and materials have significantly expanded the available fitting options for patients with corneal ectasia. Furthermore, imaging technology, such as corneal topography and anterior segment optical coherence tomography, can be applied to both gain insight into corneal microstructural changes and to guide contact lens fitting. This paper provides a comprehensive review of the range of contact lens modalities, including soft lenses, hybrid designs, rigid lenses, piggyback configurations, corneo-scleral, mini-scleral and scleral lenses that are currently available for the optical management of keratoconus. The review also discusses the importance of monitoring for disease progression in patients with keratoconus, in particular children, who tend to undergo more rapid progressive changes, so as to facilitate appropriate modification to contact lens fitting and/ or potential referral for corneal collagen cross-linking treatment, as appropriate.

“…Interaction between the contact lens and the ocular surface is a key area of interest for clinical practice. Mechanical forces exerted when the eyelid moves over the contact lens are transmitted from the anterior to the posterior surface of the lens and subsequently to the cornea and conjunctiva . Technology has exploited this interaction to improve the biomechanical interaction between the contact lens and the ocular surface; however, many questions remain about how to cope with these dynamic forces.…”
