For individuals struggling with persistent dry eye, finding an effective solution can feel overwhelming. Traditional treatments like artificial tears may only provide temporary relief. However, advancements in specialty contact lenses, particularly scleral lenses, offer new hope. At Colorado Eye Clinic in Greenwood Village, Dr. Abed Namavari, a renowned dry eye specialist, is helping patients regain comfort and clarity with this innovative approach.
What Are Scleral Contact Lenses?
Scleral lenses are large, gas-permeable contact lenses that rest on the sclera (the white part of the eye) instead of the cornea. Unlike traditional lenses, which sit directly on the corneal surface, scleral lenses vault over the cornea, creating a tear-filled reservoir that provides constant hydration.
Key characteristics of scleral lenses include:
- Size: Larger than conventional lenses, offering enhanced stability.
- Material: Rigid and gas-permeable, ensuring excellent oxygen flow to the eye.
- Customization: Tailored to fit each patient’s unique eye shape for maximum comfort.
How Scleral Lenses Help with Dry Eye
Dry eye occurs when the eyes fail to produce enough tears or when the tears evaporate too quickly. Symptoms include burning, redness, sensitivity to light, and a gritty sensation. For patients with moderate to severe dry eye, scleral lenses provide targeted relief by:
- Creating a Moisture Reservoir:
The space between the lens and the cornea is filled with saline solution, maintaining consistent hydration throughout the day. - Protecting the Cornea:
By vaulting over the cornea, scleral lenses shield it from external irritants like wind, dust, and dry air. - Enhancing Tear Stability:
The lenses stabilize the tear film, reducing symptoms like dryness and irritation.
Conditions That Benefit from Scleral Lenses
While primarily designed for patients with irregular corneas, scleral lenses are increasingly used to treat severe dry eye and related conditions. Common conditions treated with scleral lenses include:
- Severe dry eye syndrome
- Keratoconus or corneal irregularities
- Ocular graft-versus-host disease (GVHD)
- Post-surgical complications, such as after LASIK or corneal transplants
Scleral Lenses vs. Other Dry Eye Treatments
Patients often ask how scleral lenses compare to other dry eye treatments, such as artificial tears, warm compresses, or prescription medications. While these approaches can help manage symptoms, scleral lenses address the underlying issues by providing continuous hydration and protection.
| Treatment | Benefits | Limitations |
|---|---|---|
| Artificial Tears | Convenient, temporary relief | Requires frequent application |
| Warm Compresses | Improves oil gland function | Effectiveness varies |
| Prescription Drops | Targets inflammation | Results may take weeks to appear |
| Scleral Lenses | Provides long-lasting hydration | Requires fitting and adjustment |
At Colorado Eye Clinic, Dr. Namavari evaluates each patient’s condition to recommend the most effective combination of treatments.
The Fitting Process for Scleral Lenses
Fitting scleral lenses requires precision and expertise. Here’s what patients in Greenwood Village, Centennial, and Southglenn can expect during their fitting process:
- Initial Consultation:
A thorough eye exam assesses the severity of dry eye and determines if scleral lenses are suitable. - Lens Measurements:
Advanced imaging technology maps the corneal surface to create a custom-fit lens. - Trial Lenses:
Patients test trial lenses to evaluate comfort and vision. Adjustments are made as needed. - Final Fit:
Once the ideal fit is achieved, patients receive their custom lenses along with instructions for proper care and handling. - Follow-Up Care:
Regular check-ups ensure the lenses are working effectively and address any concerns.
Caring for Scleral Lenses
Proper care is essential to maintain the longevity and effectiveness of scleral lenses. Patients should:
- Clean lenses daily with recommended solutions.
- Avoid using tap water to rinse or store lenses.
- Replace saline solution in the lens reservoir before each use.
- Schedule routine visits with Dr. Namavari to monitor eye health.
Frequently Asked Questions
- Are scleral lenses uncomfortable?
Despite their size, scleral lenses are often more comfortable than traditional lenses because they don’t touch the sensitive corneal surface. - Can scleral lenses correct vision?
Yes, scleral lenses can correct refractive errors like nearsightedness, farsightedness, and astigmatism while addressing dry eye symptoms. - Are scleral lenses covered by insurance?
Coverage varies by plan, but some insurance providers consider scleral lenses medically necessary for severe dry eye or corneal conditions. - How long do scleral lenses last?
With proper care, scleral lenses can last up to two years before needing replacement. - Is the fitting process time-consuming?
While the fitting process involves multiple visits, the long-term benefits of scleral lenses make the investment worthwhile for many patients.
