To evaluate the visual outcome and intra- and post-operative complication of deep anterior lamellar keratoplasty (DLKP) in patients with keratoconus
Five patients who were diagnosed as havingadvanced keratoconus underwentDLKP. Donor cornea devoid of endothelium and Descemet membrane was transplanted onto a recipient bed after deep lamellar dissection using hydrodissection technique and removal of recipient stroma. The main outcome measures included visual acuity, refractive error, topographic astigmatism, and presence of intra- and post-operative complications.
The mean age of the patients was 23.6 years (range : 19~26 years). There was no intraoperative complication in al cases. The mean postoperative follow-up period was 12 months (range : 7~19months). The mean postoperative visual improvement was five lines of Snellen visual acuity and all patients achieved best-corrected visual acuity of 20/40 or better at the end of follow-up period. Postoperative topographic astigmatism ranged from 3.6 to 8.1D. During the follow-up period, transient elevation of intraocular pressure was noted in one patient. No case of graft rejection was observed.
DLKP using hydrodissection technique is a good option for the primary surgery in patients with advanced keratoconus.
