Summary

Cataracts are a clouding of the lens of the eye. Cataract surgery replaces the cloudy lens with a clear artificial lens. It is one of the leading causes of low vision worldwide. Since cataracts are mostly age-related, the number of patients with cataracts is increasing sharply due to an ageing population. The indication for cataract surgery is currently based on the visual impairment experienced by the patient, a measurement of visual acuity and the ophthalmologist's assessment of the extent to which the clouding of the lens explains the patient's symptoms.

It has been said that after cataract surgery, "the world opens up to you". However, about 10% of patients actually experience worse vision after surgery. This amounts to almost a whole month of potentially unnecessary surgery. It is therefore important to develop a more objective indicator for cataract surgery.

Our study focuses on measuring the optical quality of the eye before and after cataract surgery. The investigators also ask patients before and after cataract surgery how patients themselves perceive the quality of their vision. The investigators do this with different patient-reported outcomes. The investigators investigate whether the objective measurement of the optical quality of the eye can predict which patients will be satisfied with the cataract surgery. With this, the investigators aim to further improve patient care and prevent unnecessary surgery.
