MMP-8 , MMP-9 , and LCN2 were significantly lower at the end of surgery in VG compared with those in NVG patients ( MMP-8 [ ng/mL ] : 7.1 [ 3.5 ] versus 12.5 [ 7.7 ] , P = 0.02 ; MMP-9 [ ng/mL ] : 108 [ 42 ] versus 171 [ 98 ] , P = 0.029 ; LCN2 [ ng/mL ] : 109 [ 42 ] versus 171 [ 98 ] , P = 0.03 ) .
