Brief summary

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 Distance Corrected Near Visual Acuity	postoperative visit 3-6 months	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.
Post-operative Distance Corrected Intermediate Visual Acuity	postoperative visit 3-6 months	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.
Defocus Curve	postoperative visit 3-6 months	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.
Quality of Vision Questionnaire	postoperative visit 3-6 months	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.

Secondary

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