The present study is designed as an exploratory study, seeking to investigate the correlation of patient complaints to subjective or objective measurement methods. Better understanding of causative factors of negative dysphotopsia will improve detection and maybe prediction of this optical phenomenon.

RECRUITINGIdentification of factors or a combination thereof that may cause negative dysphotopsia
Biometry, Anamnesis, visual field, psychological questionnaires, wavefront aberrometry will be used to analyse if a factor causative for negative dysphotopsia can be detected
Time frame: 2 hours
Method to standardize characterization of negative dysphotopsia
New approaches like Goldmann visual field are used to try to picture negative dysphotopsias and patients will also be asked to draw the "dark shadows"
Time frame: 20 minutes
Correlation between eye biometry, patient complaints and psychophysics
Eye biometry will be measured using IOL Master 700, patient complaints will be asked during an patient-doctor interview, and psychophysics will be assessed using a psychological questionnaire
Time frame: 30 minutes
