Presbyopia-correcting implant (PC-IOL): AcrySof IQ Vivity (Alcon) has been evaluated in 2 large pivotal trials (US and OUS trials). These tests showed that this PC-IOL restored intermediate visual acuity (IVA) and near visual acuity (NV A) superior to that of the reference monofocal AcrySof implant. In these tests, it was demonstrated that distance visual acuity (DVA) was non-inferior. However, the intermediate visual acuity for this implant in its toric version has not been evaluated.
Study Type
OBSERVATIONAL
Enrollment

Distance corrected intermediate monocular visual acuity
Intermediate monocular visual acuity (at 66 cm) corrected for distance vision (DCIVA) for the eye under study in photopic condition (normal lighting) 3 months after implantation of the 2nd eye
Time frame: month 3
rotational stability
Rotational stability of the IOL in the eye under study expressed in degree of rotation at 3 months compared with that collected just after surgery in the operating room
Time frame: month 3
residual astigmatism
measure of total residual astigmatism including corneal and internal astigmatism in dioptries
