Phototherapeutic keratectomy is considered for payment when used as an alternative to lamellar keratoplasty in the treatment of visual or irritative problems related to to corneal scars, opacities or dystrophies that extend beyond the layer epithelial.
Phototherapeutic keratectomy is not considered for payment under the following conditions:
Description
Tuberculosis of the eye
Keratoconjunctivitis due to Herpes zoster
Herpes simplex conjunctivitis
Measles keratoconjunctivitis
Keratoconjunctivitis epidemic
syphilitic interstitial keratitis
Keratitis or keratoconjunctivitis in exanthema
Triple-S, Inc. will cover phototherapeutic keratectomy only in those situations where it is recognized as medically necessary as specified in this policy, in those policies that specifically cover it.
None of the refractive keratoplasties are considered for payment. This is a generic term to designate all those surgical procedures that are performed into the cornea of ​​the human eye for the specific purpose of improving vision by changing the refractive index of the corneal surface. Refractive keratoplasty includes following surgeries:

Refractive keratoplasty includes following surgeries:
· Radial keratotomy (RK) is the surgical correction for myopia. The surgeon using a microscope, he makes microincisions in the cornea, in a radial way. When healing, the convexity of the central part of the cornea is reduced, improving vision.
· Refractive keratotomy (PRK) is the use of the “excimer” laser to reshape the cornea evaporating small particles of tissue from the cornea, enough to correct myopia, hyperopia or astigmatism. This process takes 10-20 minutes. The use of laser takes between 15-40 seconds.
· Computerized lamellar keratoplasty (ALK) in this procedure removes a slice of the most anterior part of the cornea. When repositioning and healing this increases the convexity of the cornea correcting the flattening of the cornea present in the hyperopic condition.
· Conductive keratoplasty (CK) reshapes the cornea with one or two circles parallel concentric using laser.
