Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary objective is to explore monocular and binocular visual acuity, measured in logMAR, at near and intermediate distances (40–80 cm) 3–6 months after IOL implantation. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary objectives include investigating potential associations between visual acuity and anatomical characteristics of the eye. Biometric parameters of the globe, anterior chamber, lens, and cornea will be assessed to identify associations between visual acuity measurements and anatomical variations. | — |
