Abstract

Purpose: To determine the effect of retained DONOR DESCEMET MEMBRANes (DMs) on visual outcomes following DEEP ANTERIOR LAMELLAR KERATOPLASTY (DALK).Methods: In this retrospective comparative study, keratoconic eyes undergoing DALK using the BIG-BUBBLE TECHNIQUE were enrolled. A bared DM was achieved in all cases. A donor cornea without (group 1; 48 eyes) or with (group 2; 22 eyes) DM was sutured to the recipient bed. The 2 groups were compared in terms of best spectacle-corrected visual acuity, keratometric astigmatism, refractive error, contrast sensitivity (CS), higherorder aberrations (HOAs), and central graft thickness at least 3 months after complete suture removal.Results: The mean follow-up duration was 23.2±6.9 months in group 1 and 26.5±6.5 months in group 2 (P=0.61). The postoperative best spectacle-corrected visual acuity was 0.18±0.08 logMAR and 0.24±0.30 logMAR, respectively (P=0.36). The 2 groups had comparable postoperative keratometric astigmatism, spherical equivalent refraction, and HOAs. In terms of CS, however, group 1 demonstrated better results at a low spatial frequency. The mean postoperative central graft thickness was greater in group 2 (589.8±34.5 mm) than in group 1 (523.6±63.0 mm; P<0.001).Conclusion: DALK using the BIG-BUBBLE TECHNIQUE for KERATOCONUS may give better results in terms of CS if a donor cornea without DM is transplanted.
