The primary objective of the database is to retrospectively analyse the visual and refractive outcomes of cataract and refractive procedures in order to continuously assess outcomes and also compare outcomes between the different IOLs, or the different refractive procedures.

Post-operative Uncorrected Near Visual Acuity
For intraocular lens offering a visual benefit at near and/or intermediate, such as multifocal IOLs, EDoF (Extended Depth of Focus) IOLs, enhanced monofocal IOLs, and for refractive procedures offering a visual benefit at near and/or intermediate, additional visual outcomes and safety outcomes may be assessed.

Time frame: postoperative visit 3-6 months
Comparative analysis - Different types of IOLs
Comparative analysis between different types of IOLs might be performed to investigate whether one IOL might offer additional benefits to patients compared to another IOL.
Time frame: postoperative visit 3-6 months
Comparative analysis - Refractive procedure
Comparative analysis between different types of refractive procedures might be performed to investigate whether one procedure might offer additional benefits to patients.
Time frame: postoperative visit 3-6 months
