Scleral Lenses for Severe Dry Eye: How Liquid-Reservoir Lenses Provide All-Day Relief

Severe dry eye can make everyday activities uncomfortable, especially when traditional eye drops provide only temporary relief. Burning, grittiness, fluctuating vision, redness, and sensitivity can interfere with reading, computer use, driving, and wearing regular contact lenses.

At Forefront Eye Care, scleral lenses are one option we may recommend for patients with moderate to severe dry eye. Unlike standard contact lenses, scleral lenses create a fluid-filled reservoir over the cornea, helping protect and hydrate the eye throughout the day.

How Do Scleral Lenses Help Severe Dry Eye?

Scleral lenses are larger than traditional soft or gas-permeable contact lenses. Instead of resting directly on the cornea, they vault over it and rest on the white portion of the eye, known as the sclera.

Before insertion, the lens is filled with preservative-free saline. This creates a reservoir of fluid between the lens and the corneal surface. For someone with severe dry eye, that layer of fluid can provide continuous hydration while also protecting the sensitive cornea from exposure and irritation. This design can be especially valuable when the ocular surface has become too sensitive for traditional contact lenses.

Benefits of the Liquid Reservoir

Because scleral lenses maintain fluid over the cornea while they are worn, patients may experience several benefits:

•          Sustained hydration for the corneal surface

•          Reduced exposure to wind, dry air, and other environmental irritants

•          Less friction between the eyelids and a sensitive cornea

•          Improved comfort for some patients with advanced dry eye

•          Clearer, more stable vision when an irregular tear film causes fluctuating vision

The goal is not simply to cover up dry eye symptoms. Scleral lenses can become part of a broader management plan designed around the health and condition of your ocular surface.

Who May Benefit From Scleral Lenses?

We may consider scleral lenses when severe or persistent dry eye is not adequately controlled. They are also useful for patients with ocular surface disease, irregular corneas, or certain conditions that make standard contact lenses difficult to fit.

Every case of dry eye is different. Symptoms can result from poor tear production, excessive tear evaporation, inflammation, meibomian gland dysfunction, demodex blepharitis, structural eyelid abnormalities, environmental factors, or a combination of causes. A detailed evaluation helps us determine whether scleral lenses are appropriate and whether additional dry eye treatments should be included in your care plan.

A Customized Fit Matters

Scleral lenses require specialized fitting expertise. Forefront Eye Care (formerly Korb & Associates) is known as one of Boston’s oldest specialty contact lens clinics.  Dr. Nau is a Diplomate in the Cornea and Contact Lens and Refractive Technology section of the American Academy of Optometry, an honor earned by fewer than 1% of practicing optometrists worldwide.  Both she and Dr. McLeod have lead specialty lens clinics in academic medical centers and have fit thousands of patients with scleral lenses. Importantly, we have a deep knowledge of the underlying conditions for which they are fit, have expertise in how to manipulate lens optics to achieve optimal visual outcomes, and understand how to achieve lens comfort in the setting of dry eye disease.  

If persistent dry eye is affecting your comfort or vision, schedule an evaluation with Forefront Eye Care to find out whether scleral lenses could be part of your personalized treatment plan. Visit our office in Boston, MA, or call (617) 322-0534 to book an appointment.
