The document discusses three primary post-operative complications of corneal refractive surgery: corneal striae, epithelial ingrowth, and diffuse lamellar keratitis. It focuses on corneal striae, outlining the pattern and presence of fibrosis in long-standing cases. Various techniques for managing corneal striae are presented, including re-floating the corneal flap, using hypotonic saline or phototherapeutic keratectomy to smooth striae, and epithelial debridement.

5. Corneal Striae Management
• Pattern of Striae
– vertical, horizontal, oblique,
– diffuse pattern striae usually indicates
with thin flaps
• Presence of Fibrosis
– indicates long-standing nature
– reduced success in management
– need for PTK
