Contrast sensitivity—your ability to see subtle differences in shades—may change after PRK, affecting real-world vision.
Even with 20/20 vision, reduced contrast sensitivity can impact daily tasks like night driving and reading, especially after PRK.
Laser eye surgery may temporarily reduce contrast sensitivity, especially in low light, but it typically improves within 3–6 months.
Most patients regain normal contrast sensitivity within months after PRK with advanced wavefront-guided treatment."
Follow aftercare, use drops, avoid bright lights, and eat antioxidants to restore contrast sensitivity post PRK.
Persistent night vision issues, glare, or halos beyond 6 months post-op may signal a concern—consult your ophthalmologist.
