Epithelial Ingrowth: Use of Topography in the Management

Epithelial ingrowth at the edge of the flap is one of the most significant complications of LASIK. Reports of the incidence of epithelial ingrowth have ranged from 0 to 20 % [1–4]. It usually presents in the early postoperative period and is known to be associated with loose epithelium, epithelial defects at the time of surgery, hyperopic LASIK correction, enhancement surgeries, flap instability, and corneal epithelial basement membrane dystrophy [1, 3–5]. While not always serious, it can progress to induce irregular astigmatism or melting of the overlying flap and threaten the central vision.
