Lens file: MaximCV

Recent years have seen a resurgence of interest in large diameter gas-permeable lenses with a number of semi- and mini-scleral lenses being launched onto the market. The advantages of these lenses are the benefit of crisp vision from a gas-permeable, combined with comfort and stability for irregular corneas and less dryness1 than with other modalities.

Improved materials offering high oxygen flow and CAD/CAM systems allowing complex and customisable lens geometries are moving these specialist lenses into the mainstream. The MaximCV mini-scleral lens from Bausch+Lomb was introduced in May 2014 and has a growing band of dedicated users throughout the UK.

The MaximCV lens design has been developed for all corneal geometries from advanced keratoconus to corneas flattened by refractive surgery or following keratoplasty. Typically, practitioners are using the lens for any irregular cornea, high astigmatism, high refractive error and cases of contact lens intolerance, and are achieving high levels of success.
