How Scleral Lenses Treatment Can Help Keratoconus

The scleral lens is uniquely designed to correct the irregular surfaces created by these cornea problems.

Corneal ectasia is a broad term for a family of conditions that cause a progressive thinning and distortion of the corneal shape.

We see through the cornea, which is the clear, central part of the front surface of the eye. Normally, the cornea has a round shape, like a ball.

Sometimes, however, the structure of the cornea is just not strong enough to hold this round shape. The normal pressure inside the eye makes the cornea bulge outward like a cone. This condition is called keratoconus.

Keratoconus is most common ectasia and affects one in every 2000 people in the United States.

Ectasia’s may also occur after refractive surgery (LASIK or PRK) or corneal transplants.

How the Scleral Lens Helps

Scleral Lenses are a technology that creates a Prosthetic Replacement for the Ocular Surface Ecosystem (PROSE).

The scleral lens performs 3 critical tasks for the patient with dry eye:

  1. Fits under the lids and rests on the white sclera of the eye. By vaulting over the cornea it protects it from the irritation caused by blinking and outside environment.
  2. The vaulting of the lens traps a soothing bath of artificial tears that constantly refreshes the ocular surface.
  3. Creates an almost perfectly smooth ocular surface that provides clear and sharp vision without glare.

The Scleral Lens consists of clear multilayered domes made out materials with very high oxygen transmission.

One example is the Boston XO2 which is an FDA approved gas permeable material, allowing for very high amounts of oxygen to transfer through the material to the corneal surface.

Ocular GVHD Symptoms

chronic ocular GVHD
Severe dry eye from Ocular GVHD.

In 2009, the Boston Foundation for Sight conducted a survey of 51 patients suffering from ocular GVHD and found:

  • 96% had moderate or severe eye pain
  • 87% had difficulty reading regular print, newspapers, magazines or websites
  • 85% were very worried about their sight
  • 80% had trouble with work or hobbies that require seeing close up
  • 75% had trouble driving at night

In a study led by the Fred Hutchinson Cancer Research Center in Seattle, researchers found using scleral lenses to be a safe and effective treatment for patients with severe eye dryness and inflammation as a result of GVHD.

76% of the patients reported significant success with scleral lenses.

Outcomes and Results

A 2008 study of patients with ocular surface disease treated with scleral lenses, including 45% with dry eye, reported a 73% reduction in ocular pain and a 90% increase in mental health. Benefits and Cost-Effectiveness of the Boston Ocular Surface Prosthesis, Schneider Institute for Health Policy, Heller School, Brandeis University April 18, 2008 Hundreds of patients with chronic ocular GVHD have had their vision restored and quality of life transformed with Scleral Lenses.

For most people with severe ocular GVHD dry eye, scleral lenses are the only path to restoring their vision, alleviating pain and returning to functional lives.

Patient Comments
