Corneal GP lenses provide several benefits that may not be found in alternative designs. The first is their unique optics, delivering unparalleled visual acuity, especially in cases of severe refractive error, moderate-to-severe corneal astigmatism, and presbyopia. The ability to modify all corneal GP lens parameters, including quadrant-specific adjustments, allows the lens/cornea relationship to be optimized while minimizing physiological compromise.
Gas permeable (GP) contact lenses, also known as rigid gas permeable (RGP) lenses, are hard contact lenses made of silicone-containing compounds that allow oxygen to pass through the lens material to the eye.
Corneal GP lenses may be a first choice for patients who are dissatisfied with their vision with their current soft lens correction or who have moderate-to-high refractive errors, including corneal astigmatism. Presbyopes in particular are better served with corneal GP lenses than with any other technology, especially in the presence of refractive and corneal astigmatism.
