Corneal RGPs (Rigid Gas Permeable)

Corneal RGPs (Rigid Gas Permeable) are a type of contact lens that offers excellent vision correction and durability. Made from rigid materials that allow oxygen to pass through, these lenses sit directly on the cornea, the clear front surface of the eye. Due to their rigid nature, they provide a stable and precise vision correction, especially for individuals with astigmatism or other refractive errors. Corneal RGPs offer sharper and clearer vision compared to soft lenses and are suitable for various eye conditions. They provide superior tear exchange, promoting ocular health, and are available in different designs, including toric lenses for astigmatism correction. With proper care and maintenance, corneal RGPs can provide long-lasting and reliable vision correction.

Key features and benefits

 

1. Oxygen Permeability: RGP lenses are “gas permeable,” meaning they allow oxygen to pass through the lens and reach the cornea. This helps maintain good eye health and ensures a healthy corneal physiology.

2. Visual Clarity: RGP lenses provide excellent visual acuity and can correct various refractive errors, such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related difficulty focusing up close).

3. Correcting those with irregular corneas.

4. Durability: These lenses are made from rigid materials, making them more resistant to lens deposits and tear film debris. They tend to last longer than soft lenses if properly cared for.

5. Lens Customization: RGP lenses can be custom-designed to fit the unique contours of an individual’s eyes. This allows for a more precise fit, potentially enhancing comfort and visual performance.

6. Eye Health: RGP lenses are known for their ability to maintain excellent eye health by allowing sufficient oxygen to reach the cornea. This feature makes them a preferred option for people who experience discomfort or dryness with soft lenses.

7. Stability and Centering: Due to their rigid nature, RGP lenses tend to maintain their position on the cornea better than soft lenses. This stability contributes to consistent vision and reduces lens movement during blinking.

8. Lens Handling: RGP lenses are easier to handle than soft lenses, making them a good choice for those who struggle with lens insertion and removal.

Rigid Gas Permeable (RGP) contact lenses are a type of hard contact lens made from durable, rigid materials. Unlike soft contact lenses, which are made from flexible hydrogel or silicone hydrogel materials, RGP lenses maintain their shape on the eye due to their rigid nature. These lenses are designed to sit directly on the cornea, the clear front surface of the eye, and are a popular choice for individuals with various vision and eye conditions.

FAOI, FIACLE, FBCLA, Bsc Hons Optom,

Cian graduated from Dublin Institute of Technology in 2014 with an honours degree in Optometry. During his time in DIT, he was awarded a clinical placement at the University of Houston College of Optometry in Texas, where his passion for fitting medical contact lenses began. Seeing what a huge impact these lenses could have on patients’ vision made Cian realise this was where he wanted to concentrate his efforts. On returning from Houston, Cian was admitted as a Fellow of the Association of Optometrists Ireland and began his career at the prestigious Wellington Eye Clinic in Dublin. At the Wellington Eye Clinic, Cian began fitting medical contact lenses as well as performing refractive evaluations for patients looking to undergo LASIK, PRK, ICL and other intra-ocular surgeries. In 2021, Cian began working at the Royal Victoria Eye and Ear Hospital where he is the head of medical contact lens services. Cian is a Fellow of the British Contact Lens Association (FBCLA) and a Fellow of the International Association of Contact Lens Educators (FIACLE), the only Irish optometrist to hold this qualification.”

Thanks Cian, having been to many opticians for years telling me that I could never wear contact lenses, I am finally glasses-free.

After many years of having to wear glasses, I am finally able to wear contact lenses, thanks to Cian. Mountain biking in the rain is so much more enjoyable now!!
