Topo-guided PRK is an advanced technique that refines the cornea's surface for sharper, more precise vision.
What Is Topo-Guided PRK?
Topo-guided PRK, or topography-guided photorefractive keratectomy, uses extensive corneal mapping to guide laser corrections. Traditional methods apply uniform tissue removal, but topo-guided PRK strategically adjusts your cornea in areas requiring specialized fine-tuning.
The procedure begins by removing the cornea's outer epithelial layer. Then, using topographic data, the laser corrects irregularities to enhance focus. It's an ideal route for those needing a more personalized approach, especially when corneal conditions or irregular astigmatism make standard LASIK less suitable.
