LASIK surgery involves creating a flap in the cornea to reshape it, while PRK is a surface-based procedure where the outer layer of the cornea is removed. They are general terms for procedures that access the main part of the cornea, the stroma, that can be reshaped. The stroma is covered by a clear skin layer which must either be removed (PRK), or accessed by creating a flap of a thin layer of stroma and the clear skin on top. Both surgeries correct vision, but the recovery process and candidacy may vary. Dr. Motwani performs both regularly, and has created specialized versions such as trans-epithelial topography graphic guided PRK that is utilized for corneal repair. Dr. Motwani can guide you towards the best option for your individual needs.
