Objective:
To observe the indication, surgical principle, clinical results and complications of microkeratome-assisted deep lamellar endothelial keratoplasty (DLEK).
Methods:
DLEK was performed in six patients with bullous keratopathy. One of the six patients underwent DLEK combined with vitrectomy under temporary artificial corneal and intraocular foreign-body removal. Another underwent DLEK combined with vitrectomy and posterior chamber intraocular lens implantation. The patients were followed up for 6 approximately 9 months.
Results:
The postoperative best-corrected visual acuity showed clear improvement in 5 cases. Endothelial cell density averaged (2481 +/- 212) cells/mm(2). Pachymetry averaged (549 +/- 61) micro m. Astigmatism averaged (2.04 +/- 1.19) D. No serious complication was found.
Conclusion:
DLEK is an alternative choice for PKP. It may offer further advantages over conventional PKP surgery, and could serve as a surgical technique in endothelial keratoplasty. A long-term follow-up in a larger patient population is needed to confirm our initial results.
