Description:
• Keratoconus is a degenerative non-inflammatory disorder of the cornea that results in progressive thinning and abnormal protrusion of the cornea. Distortion of the cornea results in decreased visual acuity (e.g., astigmatism and myopia).
•
Phototherapeutic Keratectomy (PTK) is performed to treat corneal scars, recurrent erosions, corneal
dystrophies, and correct refractive errors caused by a diseased cornea such as keratoconus. PTK and corneal
transplant are also performed to treat damage to the cornea caused by inflammatory, infectious, and
traumatic conditions.
•
Corneal collagen cross-linking (CXL) is a procedure that uses UV light and a photosensitizer, such as
riboflavin, to strengthen collagen bonds in the cornea to help restore the normal shape of the cornea, slow
the process of keratoconus, and restore visual acuity.
•
Intrastromal corneal ring segments (INTACS) are prescription inserts that are fitted under the cornea to
elevate the edge of the cornea to correct the corneal shape and improve visual acuity.
• Scleral Shell lenses (also known as scleral lenses): Scleral Rigid Gas Permeable (RGP) lenses are very large (15 to 24 mm) lenses made to completely vault over the cornea. Scleral lenses also include prosthetic replacement of the ocular surface ecosystem (PROSE) treatment devices. These lenses are designed to extend beyond the cornea to rest on the sclera. They retain a layer of tears between the lens and the cornea.

•
Keratoplasty (Corneal Transplant) is typically performed when glasses and contact lenses are no longer
helpful to correct visual acuity. Keratoplasty can be performed in conjunction with cataract removal.
Human cadaver corneal tissue is typically used for transplant. Artificial corneas (keratoprosthetics) have
been developed and are proposed in cases of repeated failed cadaver transplants. Keratoprosthetics
require review by the Health Plan’s Medical Director.
Indications of Coverage:
Note: Many health plans have specific coverage and exclusions for vision services, contact lenses, and implantable specialty lenses. When not specified by the health plan, scleral shell lenses are considered therapeutic contact lenses.
I. Scleral Shell Contact Lenses:
Scleral shell contact lenses and fittings are considered medically necessary when there is failure of topical medications, glasses, and contact lenses and at least one of the following:
A. Corneal ectatic disorders (e.g., keratoconus, keratoglobus, pellucid marginal degeneration, Terrien’s marginal degeneration, Fuchs’ superficial marginal keratitis, post-surgical ectasia).
B. Corneal scarring and/or vascularization
C. Ocular surface disease (e.g., severe keratoconjunctivitis sicca/dry eye), persistent epithelial defects, neurotrophic keratopathy, exposure keratopathy, graft vs. host disease [GVHD], sequelae of Stevens Johnson syndrome, mucus membrane pemphigoid, post-ocular surface tumor excision, post-glaucoma filtering surgery) with pain and/or decreased visual acuity.
D. When prescribed to support orbital tissue (e.g., eye shrunken by inflammatory disease).
Replacement lenses are considered medically necessary if there is a change in the eye condition (not including refractive changes). Note: Replacement of lenses that are lost, damaged, or requested solely due to refractive changes are typically not covered under the health plan.
II. Corneal Transplant (Keratoplasty) using cadaver tissue is considered medically necessary for any of the following conditions in which standard conservative treatments (e.g., medications, glasses, contact lenses, and scleral shell lenses lenses) have failed or are contraindicated:
A. To improve vision due to corneal opacity when best corrected vision still causes interference with activities of daily living (ADLs).
B. To remove active corneal disease including keratoconus, corneal scaring with opacity, bullous keratopathy, Fuchs and other corneal dystrophies, and infectious / inflammatory keratitis after appropriate pharmacologic therapy (e.g., severe fungal, viral, bacterial or amoebic inflammation).
C. To restore altered corneal structure or prevent loss of the globe after puncture injury.
D. Failure or rejection of previous corneal transplant.

III. Intrastromal corneal ring segments, ICRS (INTACS) are considered medically necessary under the FDA approved humanitarian option when all of the following are met:
A. Corneal transplantation is the only remaining option to improve the individual’s functional vision.
B. Progressive deterioration in vision, such that the individual can no longer achieve adequate functional vision on a daily basis with their contact lenses or glasses.
C. Individual is age 21 years or older.
D. Clear central corneas (no scarring or disease).
E. Corneal thickness of 450 microns or greater at the proposed incision site.
IV. Conventional (epithelium-off) Corneal Collagen Cross-Linking (C-CXL) is considered medically necessary as a one-time treatment when all of the following are met:
A. Diagnosis of keratoconus with progressively worsening vision or progressive corneal ectasia (that is not the result of previous LASIK procedure/refractive eye surgery).
B. Individual is at least 14 years of age.
C. Corrected vision with eyeglasses or contact lenses is not adequate (is worse than 20/20).
D. Central corneas have no scarring or disease.
E. Corneal thickness of at least 400 microns (verified with pachymetry).
F. Procedure is performed using a U.S. Food and Drug Administration (FDA)-approved device, drug solution, and protocol. (At the time of this guideline printing, only the Glaukos iLink KXL System® used with riboflavin solution Photrexa® or Photrexa Viscous® [following the Dresden protocol that was used in the clinical trials] is FDA-approved in the United States).
