Submitted to deep anterior lamellar keratoplasty (DALK) using the big-bubble technique.
Procedure: Deep anterior lamellar keratoplasty (DALK)
Deep anterior lamellar keratoplasty (DALK) using the big-bubble technique.
Other Name: GROUP 1: DALK
Active Comparator: 2
Submitted to regular penetrating keratoplasty
Procedure: Penetrated keratoplasty
Regular corneal transplant using the penetrated keratoplasty technique
Other Name: GROUP 2: PK
Purpose: To report outcomes of deep anterior lamellar keratoplasty (DALK) using the big-bubble technique.
Methods: Thirty four unselected consecutive patients were submitted to DALK big-bubble technique. Intraoperative and postoperative complications, postoperative uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), spherical equivalent (SE), corneal topography, and endothelial cell density were evaluated. All patients were followed for at least 6 months.
