Transepithelial PRK or Advanced surface ablation is laser correction performed on the surface of the cornea. It is a bladeless, touchless laser wherein the excimer laser first removes the epithelium and then sculpts the underlying tissue to corrects the patients refractive error.
Visual Outcomes with ‘No Touch‘ PRK are extremely predictable, accurate and very comparable to LASIK. However, vision improvement is more gradual and the final result can take a few weeks to be achieved.
No Touch PRK offers distinctive benefits for certain patients. As the correction is directly on the surface, PRK provides more tissue available for treatment. This is of benefit for patients with thinner cornea or those with higher glass power. The absence of the corneal flap is also appealing to the more conservative patients or those who participate in extremely physical activities such as combat sports. Recruiters for vocations such as law enforcement, military and firefighting generally recommend ‘No Touch‘ PRK. While PRK offers premium safety and visual outcomes, due to the longer vision recovery and short-term discomfort, those who choose PRK do need to exercise more patience during the healing process
