Brief Summary

Cataract surgery presents an extremely high success rate in improving vision and quality of life and it is currently the most commonly performed ophthalmic surgery, especially considering its growing utility in the aging population (e.g., more than 20 million worldwide underwent the procedure in 2015); it is possible to affirm that benefits clearly outweigh risks.

However, although cataract surgery is highly effective and relatively safe, owing to the enormous numbers, even uncommon surgical complications could potentially harm the patients. For this reason, it is essential to continue to consider the possible risks and undesirable side-effects associated to cataract surgery, such as post-cataract endophthalmitis (POE), postcataract opacification (PCO), PCME, dysphotopsias, retinal detachment, and IOL dislocation.

Detailed Description

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.
