Outcome Measures
Primary Outcomes (1)
Reading speed
Reading speed in the 3 different IOL groups (EROV, monofocal, minimonovision) will be assessed using the EyeTracker device. Patients are asked to read 4 texts with different contrast levels. The faster the patients can read the texts, the better the outcome.
12 months
Study Arms (1)
Intraocular lens types
EXPERIMENTALPatients with different types of IOLs (EROV, monofocal, minimonovision) are tested for their reading quality using the EyeTracker device
Interventions
The EyeTracker is used to determine reading quality of patients with different intraocular lens types (EROV, monofocal, minimonovision)
Eligibility Criteria
You may qualify if:
- Age 21 and older
- Written informed consent
- Extended range of vision group: Patients with EROV intraocular lenses and a best-corrected Snellen VA above 0.7 in the weaker eye. Furthermore, the VA of the better eye has to be at least 0.8 (uncorrected visual acuity) and the difference between the eyes should be between 0.5D and 1D)
- Minimonovision standard IOL group: Patients with monofocal intraocular lenses and a best-corrected Snellen VA above 0.7 in the weaker eye. Furthermore, the VA of the better eye has to be at least 0.8 (uncorrected visual acuity) and the difference between the eyes should be between 0.75D and 1.50D)
- Single focus distance vision group: Patients with monofocal intraocular lenses and a best-corrected Snellen VA above 0.7 in the weaker eye. Furthermore, the VA of the better eye has to be at least 0.8 (uncorrected visual acuity) and both eyes should have a spherical equivalent between +0.25D and -0.5D
- Maximum of allowed Cylinder: +0.75D
- Fluent in German
You may not qualify if:
- Opacities, such as corneal scars
- In case of pregnancy (pregnancy test will be taken preoperatively in women of reproductive age)
