A client wants "eye glasses surgery" to fix nearsightedness, but was told several years ago that the corneas were too thin and flat for traditional laser in situ keratomileusis (LASIK) surgery
The nurse working in an ophthalmologist's office counsels the client to ask about which procedure? a. Corneal ring implants
b. Laser epithelial keratomileusis (LASEK)
c. Pneumatic retinopexy
d. Radial keratotomy (RK)
B
RK involves making tiny cuts in the cornea to flatten it and help with nearsightedness. This traditional eye surgery is occasionally used, but has mostly been replaced by LASIK. However, one contraindication to this procedure was having corneas that were too thin or flat. LASEK was designed for these cases. LASEK peels back a thin layer of the cornea to reshape the middle layer to correct nearsightedness. Corneal rings are inserted to flatten the cornea and reduce nearsightedness. A pneumatic retinopexy treats retinal detachment with a small gas bubble injected into the vitreous body.
