This page provides an overview of scleral contact lenses, their benefits, fitting process, and available options at Kahala Eye Clinic in Honolulu, HI. It is intended for patients with complex vision needs or those seeking alternatives to traditional contact lenses. Scleral lenses can be life-changing for individuals with conditions such as keratoconus, severe dry eye, or corneal scarring.
At Kahala Eye Clinic, we specialize in scleral contact lenses. Our custom scleral lenses are a specialized type of contact lens made of rigid gas permeable (RGP) material. They are significantly larger than standard soft lenses, typically ranging from 14.5 mm to 17.8 mm in diameter. Scleral lenses vault over the entire cornea and rest on the white part of the eye, known as the sclera, providing a new optical surface that avoids contact with the damaged cornea.
Scleral contact lenses are advanced, custom-made lenses designed for patients with complex vision issues or those who cannot be helped by regular contact lenses or glasses. These lenses are made of rigid gas permeable (RGP) material and are much larger than standard soft lenses, typically ranging from 14.5 mm to 17.8 mm in diameter. Scleral lenses vault over the entire cornea and rest on the sclera (the white part of the eye), creating a tear-filled space that protects the cornea and provides a new, smooth optical surface. They are primarily used to treat complex vision issues such as keratoconus, severe dry eye, and corneal scarring, and can significantly improve visual acuity and comfort. Scleral lenses offer enhanced comfort, improved corneal protection, and better vision, especially for those with corneal irregularities or refractive errors.
The unique design and key features of scleral lenses—such as their larger size, specific shape, and advanced customization—allow them to address specific needs and complex eye conditions that standard lenses cannot. These lenses offer precise control with 4 distinct zones and multiple advanced customization options, making them ideal for patients with unique ocular requirements.
The fitting process for scleral lenses is more complex than for traditional contact lenses, requiring precise customization to ensure optimal comfort and effectiveness, which is why a dedicated contact lens exam at Kahala Eye Clinic is essential.
Patients achieve all-day comfort, hydration, and crisp vision with custom scleral contact lenses. Scleral lenses are often the best solution to correct vision problems caused by keratoconus and other irregular corneas, especially when glasses cannot provide clearer vision, and our expertise with specialty contact lens fittings in Honolulu helps optimize those results. The fully customized scleral lens we utilize at Kahala Eye Clinic has achieved 510(K) clearance for the management of dry eye syndrome and is indicated for the therapeutic management of several ocular conditions. For many patients, this treatment offers improved visual acuity and comfort, and scleral lenses can be life changing.
When properly fitted, scleral lenses minimize discomfort and make eyes feel more comfortable by reducing direct contact with the cornea.
The fitting process for scleral lenses is highly individualized. Our optometrists use advanced diagnostic tools to map the unique shape of your eye, ensuring a precise fit that maximizes comfort and vision. This process may involve several visits to achieve the perfect fit, but the results are worth it—especially for those with complex corneal conditions.
To further enhance comfort and vision, we offer a range of custom lens sizes and designs.
Our custom scleral lenses in Honolulu are available in a range of diameters to fit your eyes perfectly. Each size is designed to provide a comfortable vault over your unique eye shape, whether you have normal corneas, post-surgical eyes, or keratoconus.
Oblate scleral lenses are slightly flatter in the center for normal or flatter corneas, while Prolate scleral lenses are steeper in the center to comfortably vault over higher or irregular corneas.
Below is a comparison of available scleral lens diameters and their recommended uses:
14.8 mm
Oblate (◉): Ideal for children, smaller eyes, flatter corneas, or standard corneal shapes.
Prolate (◎): For higher corneal elevations or eyes with smaller openings.
15.8 mm
Oblate (◉): Perfect for normal corneas, high astigmatism, or post-surgery eyes.
Prolate (◎): Designed for all types of keratoconus and corneal irregularities.
16.8 mm
Oblate (◉): Fits larger eyes, post-surgery, or patients needing extra comfort.
Prolate (◎): Ideal for larger eyes with keratoconus or ectasia conditions.

Anti-Reflective (AR) Coatings:
Reduce glare and reflections from digital screens, headlights, and bright sunlight. Our AR coatings make your vision sharper and more comfortable, especially for those who spend long hours on computers or driving at night.
Hydration & Wetting Coatings:
Scleral lenses rely on a tear-filled vault to keep your eyes healthy and comfortable. This tear reservoir provides a soothing effect similar to artificial tears, enhancing comfort for patients with dry eye syndrome. Hydration or wetting coatings enhance tear film stability, reducing dryness and improving all-day comfort, particularly for patients with dry eye syndrome who are seeking a trusted eye doctor in Honolulu.
