Overview
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.
Primary outcome measures
- Post-operative Uncorrected Distance Visual Acuity [Time frame: postoperative visit 3-6 months]
- Post-operative Distance Corrected Visual Acuity [Time frame: postoperative visit 3-6 months]
- Post-operative subjective refraction (Sphere, Cylinder, Axis) [Time frame: postoperative visit 3-6 months]
- Accuracy of post-operative refraction achieved compared to targeted refraction [Time frame: postoperative visit 3-6 months]
- Loss of best-corrected visual acuity compared to preoperatively [Time frame: postoperative visit 3-6 months]
- Occurrence of surgical complications and post-operative complications [Time frame: postoperative visit 3-6 months]
- Post-operative Uncorrected Near Visual Acuity [Time frame: postoperative visit 3-6 months]
- Post-operative Uncorrected Intermediate Visual Acuity [Time frame: postoperative visit 3-6 months]
- Post-operative Distance Corrected Near Visual Acuity [Time frame: postoperative visit 3-6 months]
- Post-operative Distance Corrected Intermediate Visual Acuity [Time frame: postoperative visit 3-6 months]
Secondary outcome measures (2)
- Comparative analysis - Different types of IOLs [Time frame: postoperative visit 3-6 months]
- Comparative analysis - Refractive procedure [Time frame: postoperative visit 3-6 months]
