Deep anterior lamellar keratoplasty for different corneal pathologies
PURPOSE: To evaluate the efficacy and safety of deep anterior lamellar keratoplasty (DALK) in the treatment of different corneal pathologies. SETTING: Al-Azhar University and El Magrabi Eye Hospital, Cairo, Egypt. METHODS: DALK was performed in 27 eyes of 25 patients with keratoconus or corneal stromal opacities without endothelial abnormalities. Surgical procedures included deep removal of corneal stroma 7 – 7.45 mm in diameter with the use of big air bubble technique and then a viscoelastic aided dissection from the Descemets membrane. A donor separation of the Descemets was done before grafting the corneal lenticule. In three cases, tiny perforation occurred which required no change of procedure. RESULTS: Intraoperative perforation of the Descemets membrane with the necessity of converting the procedure into penetrating keratoplasty occurred in five cases (16.1%) These 5 patients were excluded from the study. Postoperative BCVA ranged from 0.2 to 1.0 and astigmatism from 1.25 to 4.75 D. Postoperative complications included loose sutures, steroids induced ocular hypertension and Descemets membrane detachment in one eye causing a temporary double chamber. CONCLUSIONS: DALK is an effective procedure for treating various diseases of corneal stroma with unaffected endothelium. This technique as an extraocular procedure presents lower rates of complications with rapid recovery.
