Rigid gas permeable (RGP) contact lenses allow more oxygen to the eye than soft contact lenses and provide better and sharper vision than soft contact lenses. They are more durable, have greater deposit resistance and last longer than soft lenses.
These lenses are most useful for patients that want the best vision possible or in patients with very high prescriptions. In addition, rigid gas permeable contact lenses are also useful for patients with certain corneal diseases like Keratoconus.
As RGP lenses do not flex or bend on the eye, they can form a new surface for these patients with disease so they can see clearly.
We are dedicated to all gas permeable lens options including:
- Spherical gas permeable
- Bitoric gas permeable
- Gas permeable multifocal
- Keratoconus designs
- Corneal transplant designs
- Irregular astigmatism designs
- Paediatric designs
Are RGP contact lenses comfortable to wear?
Yes, but it may take between 10 days and 1 month before they settle in. They are less comfortable initially than soft contact lenses but after they have settled they are equally as comfortable
How do RGP contact lenses correct distorted vision?
If you have had previous eye surgery/trauma or have a condition called keratoconus then your cornea may be irregular in shape. A RGP lens vaults right over the top of your cornea to provide a new clear, regular surface resulting in clearer vision with reduced glare and haloes.
How long do RGP contact lenses last?
If the lenses are looked after and kept clean they can last for up to 2 years, in some cases even longer. We recommend regular 6 monthly checks and as long as the lenses are fitting safely, providing clear vision and are comfortable, there is no need to change them.
