Gas permeable (rigid) contact lenses
Gas permeable (GP) contact lenses provide sharper vision correction and are more appropriate than soft lenses for people with conditions such as high astigmatism, and are necessary to correct specific conditions such as keratoconus or other irregularities of the cornea. GP lenses take a little longer to adapt to and are not as flexible as soft lenses.
Other specialist contact lenses
Many other specialist lenses are available that may be used in more unusual or difficult cases, including mini scleral lenses which are fast becoming our favourite gas permeable contact lens for keratoconus, and combination lenses which can be used for other corneal conditions where we do not want a lens touching the delicate cornea of your eye.
