[Microkeratome-assisted deep lamellar endothelial keratoplasty].

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.
