Rigid gas permeable and scleral contact lenses offer advanced vision correction for patients who need more than standard soft contact lenses. At Ellis County Eye Center in Ennis, we provide specialty contact lens exams to help patients achieve clearer, more comfortable vision.
What Are Rigid Gas Permeable (RGP) Contact Lenses?
Rigid gas permeable contact lenses are firm lenses made from durable materials that allow oxygen to pass through to the eye. Unlike soft lenses, RGP lenses hold their shape on the eye, which can provide sharper vision for certain prescriptions.
RGP lenses are commonly used to correct astigmatism, high prescriptions, and some corneal irregularities. While they may require a short adjustment period, many patients appreciate the clear and consistent vision they provide.
What Are Scleral Contact Lenses?
Scleral contact lenses are larger lenses that rest on the white part of the eye rather than the cornea. This design creates a smooth optical surface and a fluid filled space between the lens and the eye. Scleral lenses are often recommended for patients with irregular corneas, keratoconus, severe dry eye, or corneal conditions that make traditional lenses uncomfortable or ineffective.
Benefits of RGP and Scleral Contact Lenses
RGP and scleral contact lenses offer several advantages for patients with specialized vision needs, including:
- Sharper, more stable vision for complex prescriptions
- Improved comfort for patients with irregular corneas
- Options for conditions not corrected by soft lenses
- Durable lens materials designed for long term use
- Customized lens designs for each patient
These specialty lenses are designed to address both vision clarity and comfort.
Who Is a Good Candidate for RGP or Scleral Lenses?
You may benefit from RGP or scleral contact lenses if you:
- Have irregular corneas or keratoconus
- Have high astigmatism or high prescriptions
- Experience poor vision with soft contact lenses
- Have corneal scarring or other corneal conditions
- Struggle with comfort due to dry eye symptoms
Our optometrists will evaluate your eye health and vision needs to determine whether specialty contact lenses are appropriate for you.
Specialty Contact Lens Exams and Fittings
RGP and scleral contact lenses require advanced fitting and precise measurements. At Ellis County Eye Center, we provide detailed specialty contact lens exams to ensure your lenses fit properly and provide clear, comfortable vision.
Your specialty contact lens exam may include:
- A comprehensive eye exam
- Advanced corneal measurements
- Custom lens design and fitting
- Follow up visits to refine comfort and vision
Because these lenses are customized, the fitting process may involve multiple visits to achieve the best possible results.
RGP and Scleral Lenses vs. Soft Contact Lenses
While soft contact lenses work well for many patients, they may not provide clear or comfortable vision for complex eye conditions. RGP and scleral lenses offer more precise correction by creating a stable optical surface.
Our team will help you compare your options and recommend the lens type that best supports your long term eye health and vision goals.
Frequently Asked Questions About RGP and Scleral Contact Lenses
What is the difference between RGP and scleral contact lenses?
Rigid gas permeable contact lenses are smaller lenses that rest on the cornea, while scleral lenses are larger and rest on the white part of the eye. Both provide clear vision, but scleral lenses are often more comfortable for patients with irregular corneas or dry eye.
Who needs RGP or scleral contact lenses?
These specialty lenses are often recommended for patients with keratoconus, irregular corneas, high astigmatism, or vision that cannot be corrected with soft contact lenses. An eye exam can determine if these lenses are appropriate for you.
Are scleral lenses comfortable to wear?
Many patients find scleral lenses very comfortable because they vault over the cornea and maintain a layer of fluid against the eye. This design can reduce irritation and dryness for certain eye conditions.
Do RGP lenses take time to adjust to?
RGP contact lenses may require a short adjustment period as your eyes adapt to the firmer lens material. Most patients adjust within a few weeks and enjoy sharp, stable vision.
How long do RGP and scleral lenses last?
RGP and scleral contact lenses are made from durable materials and can last longer than soft lenses when properly cared for. Your optometrist will provide guidance on lens care and replacement schedules.
How do I know if specialty contact lenses are right for me?
A specialty contact lens exam at Ellis County Eye Center is the best way to determine if RGP or scleral lenses are right for your vision needs. Your eye doctor will evaluate your eye health, prescription, and comfort.
