What is Keratoprosthesis surgery?
Keratoprosthesis implantation is a procedure that involves full-thickness removal of the cornea and replacement by an artificial cornea. The Boston Type I Keratoprosthesis is currently the most commonly used keratoprosthesis device in the US.
What is Keratophakia?
[ kĕr′ə-tō-fā′kē-ə ] n. Keratoplasty in which corneal tissue from a donor is frozen, reshaped, and transplanted into the corneal stroma of the recipient to modify refractive error.
What is radial keratotomy surgery?
radial keratotomy (RK), a surgical procedure to correct nearsightedness (myopia). The technique was first developed by Russian eye surgeon Svyatoslav Nikolay Fyodorov in the 1970s.

How much does keratoprosthesis cost?
The average cost-effectiveness of the keratoprosthesis was $16 140 per QALY. Conclusions: Comparable to corneal transplantation, with a cost-effectiveness between $12 000 and $16 000 per QALY, the keratoprosthesis can be considered highly cost-effective.
What does exactly Epikeratoplasty do?
D017391. Epikeratophakia (also known as epikeratoplasty and onlay lamellar keratoplasty) is a refractive surgical procedure in which a lamella of a donor cornea is transplanted onto the anterior surface of the patient’s cornea.
What does keratomileusis mean?
Definition of keratomileusis : a surgical procedure for correcting the refractive power of the eye to improve vision that formerly involved removing, freezing, reshaping, and reinserting a section of the cornea but now typically involves reshaping the cornea in place with the use of an excimer laser — compare lasik.
Can you have LASIK surgery after radial keratotomy?
Though many surgeons opt for PRK, you can succeed with LASIK in a patient with previous RK. Here’s a step-by-step review. While many surgeons choose to perform PRK after RK, I first prefer to use LASIK as a secondary refractive procedure if the patient is a good candidate.
Can you wear contacts after radial keratotomy?
BACKGROUND: Fitting soft contact lenses (CL) after radial keratotomy (RK) has long been contraindicated. And for good reason–neovascularization along the lines of the incisions was a common complication with traditional hydrogel lenses.
How long do artificial corneas last?
1. Alphacor keratoprosthesis. Marc Muraine, M.D., and colleagues conducted a retrospective study over a decade and determined that the survival rates of corneal grafts was 79% after one year, 73% after two years, 59% after five years and 50% after 10 years.

What happened to my left eye after the epikeratoplasty?
The graft in the left eye was later removed and an anterior chamber intraocular lens was placed, though the original corneal scars from the epikeratoplasty are still visible in that eye.
Does the right eye have an epikeratophakia graft?
The right eye still has an epikeratophakia graft (easily visible on the anterior cornea in the slit beam photograph), but the vision is now limited by irregular astigmatism and corneal edema secondary to endothelial cell loss.
