Comparative Analysis of the Visual Performance and Patient Satisfaction After Cataract Surgery With Implantation of a Medicontur Monofocal (877PAY) or a Medicontur Extended Depth of Focus (877PEY) IOL

Axial length, anterior chamber depth and corneal keratometric values K1-K2. All these parameters were measured at the screening visit and at the month 3 follow-up visit, using the ARGOS® Biometer or the ANTERION® Cataract App

The fundus and other ocular structures, such as the cornea, anterior chamber, iris, pupil, crystalline lens / IOL alignment, corpus ciliare and choroid were examined at screening visit, on the day of the surgery, and at the follow up visits D1, M1, M3, M6, and M12, using the slit lamp binocular indirect ophthalmoscopy.

Monocular and binocular Uncorrected Distance Visual Acuity (UDVA) was evaluated at all visits (preoperative, D1, M1, M3, M6 and M12), using the ETDRS chart.

Monocular and binocular Corrected Distance Visual Acuity (UDVA) was evaluated at all visits (preoperative, D1, M1, M3, M6 and M12), using the ETDRS chart.

Uncorrected and Distance Corrected Intermediate Visual acuity (UIVA / DCIVA) was evaluated postoperatively at M1, M3, M6 and M12, using an intermediate chart from 67 cm.

Uncorrected and Distance Corrected Near Visual acuity (UNVA / DCNVA) was evaluated postoperatively at M1, M3, M6 and M12, using a near chart from 40 cm.

Manifest refraction was the monocular subjective refraction (Sph, Cyl, Axis) giving the best distance corrected visual acuity. It was measured at the screening visit and the follow-up visits Day 1, Month 1, Month 3, Month 6 and Month 12.

Intraocular pressure (IOP) was measured at all visits (preoperative, D1, M1, M3, M6 and M12), using a non-contact tonometer.

Visual Acuity Defocus Curve (VADC) was taken monocularly at M3, monocularly and binocularly at M6 and binocularly at M12, using the Multifocal Lens analyzer - MLA application.

Contrast Sinsitivity Defocus Curve (CSDC) was taken under photopic conditions at M6 and M12, using the Multifocal Lens Analyzer - MLA application

Contrast Sensitivity was measured using the CSV-1000 with distance correction in place at spatial frequencies of 3, 6, 12, and 18 cycles per degree (cpd). Measurements were taken under four different light conditions: * Photopic (M3 monocular and binocular, M6 binocular and M12 monocular) * Mesopic (M6 binocular) * Photopic with backlight (M6 binocular) * Mesopic with backlight (M6 binocular)

Tear film stability was assessed at screening visit and at follow-up visits M1, M3, M6, and M12 using the non-invasive Tear break Up Time (TBUT) with fluorescein dye.

The investigational device (877PEY) and the comparator (877PAY) intraocular lens models were implanted, using sutureless, small-incision phacoemulsification surgery.
