What is LASIK?

LASIK stands for Laser-Assisted In Situ Keratomileusis and is intended to reduce a person's dependency on glasses or contact lenses. The surgical procedure permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser.

What post-LASIK issues can BostonSight PROSE can help treat?

  • Moderate to severe dry eye
  • Poor vision due to ectasia - a thinning or bulging of the cornea

What is BostonSight PROSE?

Hundreds of patients with post-LASIK dry eye and poor vision - 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.

Device schematic - white

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.

Post-LASIK Symptoms and Treatment Success

A 2010 BostonSight survey of 122 people with post-LASIK dry eye and/or poor vision (41 PROSE patients) found that:

  • 83% had moderate or severe eye pain
  • 79% had difficulty driving at night
  • 68% had difficulty with work or hobbies that require seeing up close
  • 65% had difficulty reading regular print newspapers, magazines or websites

When asked about their success with various treatments:

  • 1% with punctal plugs
  • 6% with topical steroids
  • 5% with artificial tears, lubricant gels or ointments
  • 8% with topical immunosuppression (Restasis/Cyclosporine)

61% 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.

A Labor of Love

Almost immediately after surgery, James started having trouble with every day activities. “My vision was right for about a week after LASIK, and then it just kept getting worse,” he said. “The dryness was so bad that I was using artificial tears maybe 12 times a day.” more.
