An Overview of Photorefractive Keratectomy: Indications, Benefits, and Complications

Photorefractive keratectomy (PRK) is a laser eye surgery procedure that is used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. It is similar to another laser eye surgery procedure called LASIK, but there are some key differences between the two.


Indications for PRK:


Nearsightedness (myopia)

Farsightedness (hyperopia)

Astigmatism


Benefits of PRK:


Can correct a wide range of vision problems

Can be performed on patients who are not suitable candidates for LASIK surgery (e.g. those with thin corneas)

Can be used to correct vision in patients with certain occupations or hobbies (e.g. pilots, athletes) that may not be suitable for LASIK surgery due to the risk of injury to the corneal flap.


Complications of PRK:


Pain and discomfort after the surgery

Light sensitivity

Blurred vision

Dry eye

Halos or glare around lights

Under- or overcorrection of vision

Delayed healing

Infection (rare)

PRK is generally considered to be a safe and effective procedure, but as with any surgery, there are risks and potential complications. It is important to discuss these risks and any concerns with your ophthalmologist before deciding whether PRK is right for you.
