Remarkably, there is a more rapid improvement in vision and decreased discomfort with LASIK since the surface epithelial cells have been preserved and do not need to grow again. This is indisputably the reason that LASIK has become the most preferable corrective surgery for both doctors and patients. However, in some patients, PRK is a safer alternative to LASIK that may promise better outcomes. Patients who might benefit from PRK include those with less corneal tissue or in some patients with corneal irregularities or scars.
