Abstract Details

Purpose:

Evaluation of outcomes of big‐bubble deep anterior lamellar keratoplasty in cases with post‐keratitis and post‐traumatic corneal scars.

Setting:

Davangere Netralaya

Methods:

Interventional case series of patients with corneal stromal scarring secondary to healed infectious keratitis or trauma were recruited from the corneal clinic. All patients underwent big‐bubble deep anterior lamellar keratoplasty surgery. Best‐corrected visual acuity, as well as intra‐ and postoperative complications were assessed.

Results:

Mean age 39.7±11.3 years, 36 patients (25 males, 11 females) with post‐infectious keratitis (n=22) and post‐traumatic (n=14) corneal stromal scars sparing the Descemet's membrane and endothelium. Big bubble achieved in all eyes, intraoperative perforation of DM occurred in 6 eyes (16%) during stromal dissection. 2 cases required conversion to penetrating keratoplasty. A double anterior chamber occurred in three cases (8.3%). Mean preoperative BCVA (0.03±0.04) improved at the end of 6 months (0.43±0.20; P=0.01). Corneal stromal graft rejection noted in 2 cases (5.5%) during first 3 months of surgery. Graft failure occurred in two cases (5.5%). 

Conclusions:

Deep anterior lamellar keratoplasty using the big‐bubble technique is a viable option in cases with post‐infectious keratitis and post‐traumatic corneal stromal scarring with normal Descemet's membrane and endothelium.
