Deep lamellar keratoplasty for recurrent advanced pterygium.

The authors report a case of recurrent advanced pterygium managed by deep lamellar keratoplasty and conjunctival autograft. A woman presented with bilateral recurrent advanced pterygium (more prevalent in the left eye) associated with corneal thinning in the left eye. Two-thirds of the cornea was covered by pterygia. Her visual acuity was counting fingers at 1 meter in the right eye and light perception with projection of rays being accurate in all quadrants in the left eye. She underwent deep anterior lamellar keratoplasty and conjunctival autograft in her left eye. Clarity, state of corneal graft, and postoperative visual acuity were noted. The graft was clear and the patient's best-corrected visual acuity improved to 20/60 after the surgery. Deep lamellar keratoplasty with conjunctival autograft is a good option as a single-stage surgery for recurrent advanced pterygium.
