Abstract
Herein we describe a technique for management of large inadvertent full-thickness
trephination during deep anterior lamellar keratoplasty using the big-bubble technique
without converting to penetrating keratoplasty. First, the anterior chamber is formed
with an ophthalmic viscosurgical device (OVD). Then, the full-thickness wound is
secured with one X-type 10-0 nylon suture. A 27-gauge needle is attached to a 2 ml
air-filled syringe and inserted into the corneal stroma in the meridian opposite to the
site of full-thickness trephination. Air is gently injected to produce a limited area of
“big-bubble” detaching Descemet’s membrane (DM) from the corneal stroma. The
“big bubble” is slowly expanded with injection of OVD. Finally, the recipient stroma
is removed, the donor lenticule is placed and the DM tear is secured with one full
thickness 10-0 nylon suture.
