简要总结
The goal of this observational study is to learn about the intermediate and near vision in patiënts who underwent cataract surgery with a specific technique, called "bag in the lens".
The main question it aims to answer is whether patiens who underwent this type of cataract surgery have better intermediate vision without spectacle correction than patients who underwent the classic lens in the bag cataract surgery.
Participants will:
- Have to read with and without spectacle correction at different distances (4 meters, 66 centimeters, 40 centimeters)
- Have to fill in 2 questionnaires about visual functioning and spectacle independance
Researchers will compare these values to the same values from the standard population who underwent the classic lens in the bag cataract surgery with a monofocal intraocular lens .
