Summary

Primary objective of this study is to identify the optimal task lighting conditions (in terms of light intensity and light temperature) for 10 activities of daily living (ADLs) that require near or intermediate vision acuity in a validated ADL simulation framework for a sample of patients who underwent presbyopic correction with bilateral multifocal intraocular lenses (IOLs) implantation, and to compare their capacity to perform ADLs (ADL scores) between three study groups (SG): SG1. patients implanted bilaterally with trifocal diffractive IOLs, SG2. patients implanted bilaterally with bifocal hybrid (diffractive-refractive) IOLs, SG3. patients implanted bilaterally with monofocal IOLs

ADL performance

ADL performance All study groups address the following 10 ADL tasks in 9 different combinations of light temperature and light intensity in order possible differences to be revealed among the study groups and light combinations: 1\. Phone Book Search (PBS), 2. Supermarket receipt (SupRe), 3. Book reading (BR), 4. Cellular message (CM), 5. Cellular entry search (CES), 6. Reading computer screen (RCS), 7. Drops bottle reading (DR), 8. Subtitles reading (SubRe), 9. Open door test (ODT), and, 10. Screwdriver test (ST). The 9 light combinations are the following: 3000 K - 25 fc, 3000 K - 50 fc, 3000 K - 75 fc / 4000 K - 25 fc, 4000 K - 50 fc, 4000 K - 75 fc / 6000 K - 25 fc, 6000 K - 50 fc, 6000 K - 75 fc
