My colleagues and I use 000000 mild chromic surgical gut in all cases of cataract surgery, both for the corneoscleral wound and the conjunctival flap. With loss of vitreous, it is necessary when using absorbable surgical sutures to make a surgeon's knot, since the suture becomes so slippery when covered with vitreous that the ordinary square knot will not hold.
