Question

which of the following surgical procedures reshapes the cornea?
a enucleation
b laser photocoagulation
c photorefractive keratectomy
d scleral buckling

Explanation:

• Enucleation is the removal of the entire eye, not related to corneal reshaping.
• Laser photocoagulation is used to treat retinal problems (like diabetic retinopathy) by sealing blood vessels, not for corneal reshaping.
• Photorefractive keratectomy (PRK) is a surgical procedure that uses an excimer laser to reshape the cornea to correct refractive errors (myopia, hyperopia, astigmatism).
• Scleral buckling is a surgical technique for repairing retinal detachments, involving the sclera (the white part of the eye), not the cornea.

Answer:

C. photorefractive keratectomy
