Observational, Prospective Clinical Investigation on Mini 4 Ready Intraocular Lens

This is an observational, non-controlled, prospective clinical investigation to evaluate long-term safety and performance of Mini 4 Ready Intraocular Lenses in cataract patients.

Specifically the aim of the investigation is to evaluate:

• Accumulated incidence of surgical reinterventions and of achievement of visual acuity (VA) of 0.3 logMAR units or better after 1 and 2 years following IOL implant;
• Evaluation of contrast sensitivity (CS) after 1 month following IOL implant.
• Incidence and severity of posterior capsule opacification (PCO) and incidence of posterior capsulotomy after 1 and 2 years following IOL eye implant.
• Monocular and binocular uncorrected (UDVA) and corrected (CDVA)distance VA at 4 m under photopic conditions at 1 and 6 months.
• Overall refractive power, measured as manifest (subjective) and subjective refraction, standard and converted to spherical equivalent refraction at 1 and 6 months and at 1 and 2 years.
• Defocus curve of the implanted eye under photopic conditions at 1 month.
• Occurrence of surgical reinterventions for whichever reason.
• Occurrence of any adverse untoward outcome, including any adverse event (such as, but not limited to, pseudophakic cystoid macular edema (PCME), retinal detachment, signs of inflammation, surgical site infections (SSI), pupillary block, and IOL tilt and decentration).
• Accumulated incidence of surgical reinterventions and of achievement of visual acuity (VA) of 0.3 logMAR units or better after 1- and 6-months following index eye implant.

Inclusion criteria

Subjects will be deemed eligible for the study if all of the following inclusion criteria are met:

• Older than eighteen years of age at the time of surgery and diagnosed with cataract;
• Unilateral or bilateral cataract removal by phacoemulsification;
• Correction of resulting aphakia with the Mini 4 Ready IOL. Indication for use of the Mini 4 Ready should be previous to and not conditioned by study participation.
• In case of bilateral cataract, subject able to underwent second cataract surgery within 1 months from first implant and not before 7 days;
• Willing and able to complete all required postoperative visits;
• Able to comprehend and sign a statement of informed consent consistent with local regulation for research in human subjects.

Exclusion criteria

• Subjects participating in a concurrent clinical trial or who have participated in an ophthalmological clinical trial within the last 30 days.
