Practitioners

As lens material technologies continue to improve, so inevitably does the need for credible continuing professional development. Follow the links below for lens fitting advice and to access a wealth of educational resources.

Gas permeable

Gas permeable (GP) lenses are fitted almost in alignment with the cornea. The centre of the lens normally clears the apex of the cornea by ±20 microns, and the lens aligns with the periphery of the cornea to distribute the weight. Find out more

Scleral

Scleral lenses are ideal for the correction of irregularly shaped cornea, whether that irregularity has been caused by keratoconus, traumatic injury, laser surgery or a corneal graft. Find out more

Ortho-K

Orthokeratology (Ortho-K) is the process by which the corneal epithelium is reshaped overnight by a gas permeable lens to provide corrected vision during the following day after the lens is removed. Find out more

Soft & Silicone hydrogel

By their very nature, soft lenses are soft and pliable, and will therefore conform to the shape of the eye. A range of eyes may comfortably be fitted with a limited number of base curves. Find out more

Hybrid

GP lenses generally give a better visual performance than soft lenses, whereas soft lenses – such as soft and silicone hydrogels – provide better comfort. Hybrid lenses were designed to offer the benefits of both. Find out more
