Keratoconus and Corneal Ectasia
"Thanks to PROSE treatment, I was able to put off cornea transplant surgery, which, at the age of 41 when I got my treatment, was a true blessing from God."
86% of patients with keratoconus or ectasia reported significant success with BostonSight® PROSE treatment.

About Corneal Dystrophies and Ectasia
PROSE treatment can improve vision and alleviate symptoms in patients with corneal dystrophies and ectasia. Corneal ectasia is an umbrella term for a group of conditions that cause a progressive thinning and distortion of the corneal shape, including:
• Pellucid marginal degeneration
• Terrien’s marginal degeneration
• Post-LASIK, post-RK (radial keratotomy), post-PRK
• Post-cornea transplant
Together, keratoconus and post-refractive ectasia are the second most frequent indication for corneal transplantation, accounting for about 15% of the corneal transplants performed in the US.
Patients with intolerance to contact lenses, corneal scarring or pain, and/or recurrent corneal erosions due to poor fitting contact lenses are often good candidates for PROSE treatment.

How BostonSight PROSE Treatment Can Help
Thousands of patients with keratoconus, corneal dystrophies and ectasia - just like you - have had their vision restored and quality of life transformed with our innovative treatment: PROSE. BostonSight PROSE (prosthetic replacement of the ocular surface ecosystem) treatment uses FDA-approved custom made prosthetic devices to replace or support impaired ocular surface system functions that protect and enable vision.
The prosthetic devices created during PROSE are transparent domes, about the size of a nickel. They look similar to an oversized hard contact lens and resemble a margarita glass without the stem in shape. PROSE devices fit under the eyelids, vaulting the damaged cornea and resting on the sclera (the relatively insensitive white tissue of the eye). Worn during waking hours, patients are trained in daily application, removal and cleaning as part of the treatment process.
PROSE devices are made out of a highly gas-permeable hard plastic that allows oxygen to reach the cornea. They are designed to create a space between the prosthetic device and the eye that is filled with sterile saline. The liquid remains in the reservoir, providing constant lubrication by bathing the eye in a pool of artificial tears.
Benefits of BostonSight PROSE
- Reduces symptoms and supports healing by restoring a healthy ocular surface environment
- Improves blurry vision by masking irregularities on the cornea’s surface and transmitting a sharp image to the back of the eye
- Prevents further damage by protecting and shielding the cornea against the environment and eyelids
Note: The prosthetic devices used in PROSE were formerly known as Boston Ocular Surface Prosthesis (BOS-P), Boston Scleral Lens devices and Boston Scleral Lens Prosthetic Devices.

Keratoconus Symptoms and Treatment Success
A 2010 BostonSight survey of 200 people with keratoconus and other corneal dystrophies and degenerations (121 PROSE patients) found that:
- 77% had difficulty reading regular print newspapers, magazines or websites
- 73% had difficulty with work or hobbies that require seeing up close
- 69% had moderate or severe light sensitivity
- 78% had difficulty driving at night
- 59% had eye pain
When asked about their success with various treatments:
- 1% had significant success with soft contact lenses
- 7% with hybrid contact lenses
- 22% with rigid gas-permeable (RGP) contact lenses
- 45% with scleral lenses (not BOS-P or Boston Scleral Lens used in BostonSight PROSE)
86% had significant success with BostonSight® PROSE treatment*
* Survey questions refer to success with Boston Ocular Surface Prosthesis (BOS-P) and Boston Scleral Lenses used exculsively in BostonSight PROSE treatment.
