Assessment of Vivity With French Clinical Data Related to the Toric Model Study (VICTOR)
22. august 2022 opdateret af: Edouard KOCH, Versailles Hospital
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.

Studiebefolkning
Patients will be selected from among patients who come for consultation for cataract surgery.
During the inclusion visit, the doctor will inform the patients eligible for the study, and answer all their questions about the objective, the constraints, the foreseeable risks and the expected benefits of the study.
Without opposition from the patient, the doctor will perform the cataract surgery and the data will be collected on D0, M1 and M3.
Beskrivelse
Inclusion Criteria:
- Patient presenting for a request for cataract surgery in current practice: phacoemulsification followed by classic implantation of an IOL with small incision size (< 2.2mm)
- Calculated power of IOL is between 10.0 and 30.0 diopters (D) in 0.5D steps to target emmetropia (0.0 +/- 0.5D)
- Patients with corneal astigmatism > 0.5D and who can receive an implant with a toricity between T2 and T6, i.e. with astigmatism between +0.5D and +2.5D.
- If both eyes have astigmatism, the eye under study will be the right eye
- Patient having been informed and not objecting to their participation.
Exclusion Criteria:
- Pregnancy or breastfeeding while conducting the study
- Person under the age of 18
- History of pathologies of the anterior segment of the eye (cornea, anterior chamber, sulcus) or posterior segment of the eye (uvea, vitreous, retina) including retinal vascular occlusions, retinal detachment, peripheral retinal laser photocoagulation, AMD and glaucoma
- Any inflammation of the anterior or posterior segment, whatever its etiology or history of disease, which may lead to an inflammatory reaction
- Clinically significant corneal pathology (epithelial, stromal, or endothelial that could affect visual outcome)
- Clinically significant severe dry eye disease that may affect visual calculations and measurements
- History of refractive surgery
- Amblyopia or monofixation syndrome
- Patient at risk of zonular rupture during the phacoemulsification procedure and may affect the centering or tilt of the implant postoperatively.
- Irregular astigmatism (corneal topography)
- Any other planned eye surgery
