Photorefractive keratectomy (PRK) is a type of laser eye surgery designed to correct vision problems like nearsightedness, farsightedness and astigmatism. PRK came before laser procedure called LASIK, but PRK is still performed frequently and regularly with good success rate.
PRK is arguably the safest Laser Vision Correction Surgery available. It leaves the maximum residual corneal thickness amongst all Laser Vision Correction Procedures and is often the preferred procedure in cases with borderline corneal thickness.
Nowadays, we mostly perform Transepithelial or Touchless PRK where instead of mechanical or chemical removal of epithelium (top layer of cornea) we directly use laser to remove this layer.
Advantages with this procedure include:
- Faster Recovery
- Lesser Pain
- Better Comfort
