Scleral Lenses: A Customized Solution for Vision Enhancement
An Overview of Scleral Lenses
Scleral lenses use advanced design features to improve both vision and eye health. The following topics explain how these lenses work and why they feel comfortable.
Scleral lenses are large-diameter lenses made from highly gas-permeable materials. Unlike standard contacts that sit directly on the cornea, these lenses vault over it and rest on the white part of the eye, creating a smooth optical surface and therapeutic benefits.
The space between the back of a scleral lens and the cornea is filled with preservative-free saline before insertion. This fluid reservoir keeps the cornea continuously bathed in moisture, prevents evaporation, and protects the surface from blinking friction, providing both vision correction and healing.
Because scleral lenses rest on the less-sensitive sclera and avoid corneal contact, most patients find them surprisingly comfortable. Their larger size also keeps them stable, so they rarely shift or dislodge during blinking or physical activity.
Using corneal topography, our eye doctors create a detailed 3-D map of your eye. This map guides the design of a custom lens that matches your eye’s specific curves, ensuring optimal fit, comfort, and vision.
Benefits of Scleral Lenses
Scleral lenses offer multiple advantages that extend beyond basic vision correction. Below are the key benefits patients often experience.
By avoiding direct corneal contact and shielding the eye from eyelid friction, scleral lenses eliminate the sensation of a foreign object in the eye, delivering comfortable wear throughout the day.
For eyes with irregular astigmatism, scleral lenses create a perfectly smooth optical surface that neutralizes distortions, resulting in consistently crisp and clear vision.
The fluid reservoir beneath a scleral lens offers constant hydration, promoting ocular surface healing and reducing symptoms such as grittiness, pain, and dryness.
The large diameter of a scleral lens acts as a barrier against dust, debris, allergens, and wind, helping sensitive eyes remain comfortable and protected.
Scleral lenses stay firmly in place during sports and other vigorous activities, giving active individuals stable vision and confidence.
Scleral lenses address high refractive errors, significant astigmatism, and vision changes after corneal surgery or scarring, restoring functional vision when other options fall short.
Are You an Ideal Candidate for Scleral Lenses?
Candidacy depends on eye health, vision needs, and previous experiences with other correction methods. The groups below often benefit the most.
Conditions such as keratoconus, pellucid marginal degeneration, corneal ectasia after surgery, or corneal scarring make scleral lenses a primary choice for restoring clear vision.
Moderate to severe dry eye, including cases related to Sjögren’s syndrome, Stevens-Johnson syndrome, or ocular graft-versus-host disease, often responds well to the constant hydration scleral lenses provide.
Very high levels of nearsightedness, farsightedness, or astigmatism that exceed the range of traditional contacts or glasses can be corrected effectively with scleral lenses.
Patients who find rigid gas permeable lenses uncomfortable or soft lenses inadequate may discover that scleral lenses offer both comfort and superior vision.
The Scleral Lens Fitting Process
Our fitting process ensures each lens is tailored to your unique eyes for maximum comfort and vision quality.
We begin with a detailed eye examination and discussion of your visual challenges, history, and lifestyle to confirm that scleral lenses are the right choice.
A corneal topographer captures a precise 3-D map of your cornea and sclera, serving as the blueprint for your custom lenses.
Diagnostic lenses help us check edge alignment, central vault, and vessel health, fine-tuning each parameter for comfort and ocular surface protection.
Issues such as midday fogging or lens wettability are managed by refining the lens design and recommending effective care routines to keep vision clear all day.
During a hands-on training session, you learn the techniques and tools needed to insert, remove, and maintain your lenses with confidence.
Clinical Data: The Proven Success of Scleral Lenses
Extensive research supports the safety and effectiveness of scleral lenses across a range of eye conditions.
Studies show that scleral lenses can improve best-corrected vision in keratoconus patients from approximately 20/50 to better than 20/25, with high satisfaction for both vision and comfort.
Patients with severe ocular surface diseases report significant symptom relief and improved quality of life after switching to scleral lenses, accompanied by measurable reductions in corneal staining.
The global CLEAR review identifies scleral lenses as a primary option for visual rehabilitation of irregular corneas and management of ocular surface disease when fit by a skilled eye care professional.
Multiple clinical trials and academic reports continue to confirm the long-term benefits, safety, and patient satisfaction associated with modern scleral lens designs.
Frequently Asked Questions
The answers below address the most common concerns patients have about scleral lenses.
There is a learning curve due to their larger size, but one-on-one training and simple tools make insertion and removal straightforward. With practice, most patients handle their lenses easily.
Made from durable, rigid gas-permeable materials, a pair of scleral lenses can last one to three years with proper care, making them a cost-effective option over time.
Scleral lenses are designed for daily wear only. Sleeping in them can increase the risk of infection and other complications unless specifically directed by your eye doctor for a short-term therapeutic reason.

Dr. Lee performed surgery on both my eyes. My vision is perfect. Dr Lee is the best.
Chris Codner
Dr. Chin is professional and caring. He performed cataract surgery on both eyes, no issues. No pain, swelling, scratchy eyes. I highly recommend Dr. Chin.
Ann Marie Pansy
Dr. Chin is kind, professional, and provides thorough care. I recently had laser surgery for glaucoma and I’m very pleased with the results.
Michele Cucci
Dr. Bianchi is great. He is calming, with the perfect demeanor for children, especially on the autism spectrum. Wonderful experience—I wish he was also a pediatrician and dentist.
Cara Thapa
I have been going to Westwood Ophthalmology for years. I had LASIK, cataract surgery with lens implants. Couldn't have asked for better care.
