Before suction: IOP measured before laser treatment; after vacuum: IOP measured just after vacuum turned off and suction ring removed on lying patients; after phaco: IOP measured after cataract surgery; 1 day after: IOP measured at 1 day after surgery; 7 days after: IOP measured at 7 days after surgery. value1: statistical significance of IOP values compared to preoperative values; value2: statistical significance of IOP values compared to values obtained after suction phase; value3: statistical significance of the IOP difference between the two groups at each study time points. Group 1: liquid optics interface. Group 2: SoftFit™ Patient Interface.
