PRK
PRK Laser Eye Surgery: Safe Vision Correction for Thin Corneas
PRK (Photorefractive Keratectomy) is one of the most established and reliable laser vision correction procedures used to treat refractive errors such as myopia, hyperopia, and astigmatism. The procedure is especially suitable for patients with thin corneal structures or those who may not be ideal candidates for LASIK surgery.
At Özel Sistem Eye Medical Center, advanced corneal analysis and personalized treatment planning are performed to determine the safest and most effective laser treatment option for each patient.
What is PRK?
PRK is a surface-based laser eye surgery technique designed to reshape the cornea and improve the way light focuses on the retina.
Unlike LASIK, PRK does not require the creation of a corneal flap. Instead, the thin outer epithelial layer of the cornea is gently removed before the excimer laser is applied directly to the corneal surface.
This flap-free approach helps preserve corneal integrity and makes PRK a preferred option for selected patients.
Who is a Suitable Candidate for PRK?
PRK may be recommended for:
- Patients with thin corneas
- Individuals unsuitable for LASIK surgery
- Patients with mild to moderate refractive errors
- Individuals involved in contact sports or high-impact professions
- Patients with certain corneal surface irregularities
- Individuals with dry eye tendency
A detailed ophthalmic examination is essential before treatment to determine candidacy.
How is PRK Surgery Performed?
PRK surgery is performed under topical anesthesia using anesthetic eye drops.
The procedure generally includes:
- Gentle removal of the corneal epithelial layer
- Excimer laser reshaping of the cornea
- Placement of a protective bandage contact lens
The laser treatment itself usually takes only a short time, and the procedure is performed without stitches.
PRK vs. LASIK
Although both PRK and LASIK use excimer laser technology to correct refractive errors, their surgical techniques and recovery processes differ.
PRK Advantages
- No corneal flap creation
- Better suitability for thin corneas
- Reduced risk of flap-related complications
- Preferred for patients with a higher risk of eye trauma
Recovery Differences
Vision recovery after PRK is generally slower than LASIK, and temporary discomfort, light sensitivity, and tearing may occur during the initial healing period.
Recovery After PRK Surgery
During the first few days after surgery, mild discomfort, tearing, burning sensations, and light sensitivity are common while the corneal surface heals.
The protective contact lens is typically removed after epithelial healing is completed. Vision gradually improves over the following weeks, while complete visual stabilization may take several months.
Regular use of prescribed eye drops and UV-protective sunglasses is important during the recovery process.
When Should You Contact Your Doctor?
Patients should seek prompt ophthalmic evaluation if they experience:
- Severe or increasing eye pain
- Sudden vision loss or significant visual decline
- Excessive redness or swelling
- Unusual eye discharge
