About

Hanita Lenses Trifocal IOL, SeeLens AFR (Intensity IOL).Prospective, single-arm single-center, open-label study.

Full description

Device: Hanita Lenses Trifocal IOL, SeeLens AFR (Intensity IOL). Indication studied: The Hanita Lenses Trifocal IOL is intended for implantation in the capsular bag in the posterior chamber in order to replace the crystalline lens of the eye to attain visual correction of aphakia in adult patients in whom a cataractous lens has been removed, who desire improved uncorrected vision, useful near and intermediate visual functions, and reduced spectacle dependence.

Study description: This study is a prospective, single-arm single-center, open-label study.

Signed informed consent

Exclusion criteria

Previous ocular/corneal surgery that may affect refraction accuracy or visual acuity.
Capsule or zonular abnormalities that may affect postoperative centration or tilt of the lens (e.g. pseudoexfoliation syndrome, chronic Uveitis, Marfan's syndrome)
History or evidence of any ocular disease that may affect visual acuity (i.e. uncontrolled glaucoma, ocular injury, corneal pathologies, retinal pathologies in general and macular pathologies in particular, diabetic retinopathy, uveitis, aniridia or iris atrophy, vitreous pathologies (patients with vitreous separation or floaters can be included).
Rubella cataract.
Amblyopia
Any other ocular condition that may predispose a subject to future complications or contraindicate implantation of the trifocal lens.

Patients with pupil diameter greater than 4mm in photopic conditions.
Pregnant, lactating or planning to become pregnant during the course of the trial.
