Complicated, technically challenging surgery; IOL, intraocular lens; Mydrane group, patients who received an intracameral injection of a standardised combination of tropicamide 0.02%, phenylephrine 0.31% and lidocaine 1% just after the first incision; Reference group, patients who received a standard topical regimen of one drop each, of tropicamide 0.5% and phenylephrine 10% repeated three times at 10 min intervals beginning 30 min before surgery; Slightly complicated, slightly technically challenging surgery; Uncomplicated, routine surgery, not technically challenging.
