BSCVA (logMAR)	PK (n=38)	DALK (n=38)	P^a
Preoperative	1.79±0.95 (3.00-0.54)	1.81±0.87 (3.00-0.30)	0.938
Postoperative week 1	0.94±0.76 (2.00-0.30)	0.76±0.28 (1.30-0.18)	0.012^b
Postoperative month 1	0.80±0.35 (1.30-0.00)	0.53±0.23 (1.30-0.00)	< 0.001^b
Postoperative year 1	0.40±0.33 (1.30-0.00)	0.30±1.99 (0.80-0.00)	0.104

PK: Penetrating keratoplasty; DALK: Deep anterior lamellar keratoplasty; BSCVA: Best spectacle corrected visual acuity. ^aIndependent sample test; ^bStatistically significant P values.
