Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to create a patient registry that will allow for comparison of cataract treatment outcomes using phacoemulsification with implantation of different types of intraocular lenses.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will establish a registry to evaluate outcomes associated with intraocular lens implants in patients undergoing cataract surgery. Retrospective assessments will include routinely collected preoperative, intraoperative, and postoperative data. Prospectively, visual acuity, refraction, examination findings, patient-reported outcomes, and complications will be collected for up to 60 months after surgery.

Intraocular lens

Intervention Type DEVICE

Implantation of an intraocular lens following phacoemulsification cataract extraction, with lens type selected according to routine clinical practice (e.g., monofocal, toric, multifocal, or extended-depth-of-focus).

Bilateral Monofocal-plus IOL

Patients who underwent bilateral cataract surgery with implantation of monofocal-plus intraocular lenses in both eyes between 2021 and 2025, and attended a follow-up visit.

Intraocular lens

Intervention Type DEVICE

Implantation of an intraocular lens following phacoemulsification cataract extraction, with lens type selected according to routine clinical practice (e.g., monofocal, toric, multifocal, or extended-depth-of-focus).

Bilateral EDOF IOL

Patients who underwent bilateral cataract surgery with implantation of extended-depth-of-focus (EDOF) intraocular lenses in both eyes between 2021 and 2025, and attended a follow-up visit.
