	1	Comparison of visual and topographic outcomes of deep-anterior lamellar keratoplasty and penetrating keratoplasty in keratoconus显示文摘AIM:To compare visual,surgical and topographic outcomes of deep anterior lamellar keratoplasty(DALK)and penetrating keratoplasty(PK)for keratoconus(KC).METHODS:In this multicenter,prospective,randomized clinical trial 76 eyes of 71 KC patients operated between January 2011 and July 2014 in 2 tertiary referral hospitals were included. Consecutive patients were alternately selected to receive one of the two surgical methods. Thirty eight eyes underwent DALK with the big-bubble technique and 38 eyes underwent PK.RESULTS:Mean best spectacle corrected visual acuity(BSCVA)at the first postoperative week(P=0.012)and the first postoperative month(P<0.001)was statistically significantly higher in DALK group. The mean BSCVA at12 mo was not significantly different for DALK(0.30±1.99 log MAR)versus PK(0.40±0.33 log MAR)(P=0.104). The76.3% of the eyes had a BSCVA over 0.5 in DALK and 47.4%in PK group(P=0.009). The 7.9% of the eyes had a BSCVA of 1.0 in DALK and 5.3% in PK group(P=0.644). Mean spherical equivalent was-2.94 D in DALK and-3.09 D in PK group.Mean topographic astigmatism was 4.62 D and 4.18 D respectively. Regular topographic patterns were observed in 31(81.6%)of DALK and 29(76.3%)of PK(P=0.574). The most frequent topographic pattern was oblate asymmetric bow tie,seen in 39.5% in DALK and 23.7% in PK. CONCLUSION:Big bubble DALK provides an earlier visual improvement compare to PK. However,visual and topographic outcomes are similar to those in PK at 1y. Postoperative complications including rejection and intraocular pressure elevation are more frequent in PK. DALK is a safer alternative to PK for KC. However,intraoperativeperforation of the Descemet's membrane is a significant complication.
