Abstract Details


To evaluate the incidence of negative and positive dysphotopsia after bilateral cataract surgery.


University Eye Clinic, Maastricht University Medical Center, Maastricht, The Netherlands.


Files of 331 patients were screened and 95 patients met our inclusion criteria: bilateral uncomplicated cataract surgery, postoperative best corrected visual acuity of ≥ 0.8 Snellen and absence of visual consequential ocular comorbidity. The patients were implanted with AcrySof IQ (174 eyes), Acrysof MN60MA (2 eyes), Finevision Micro F trifocal (10 eyes), Acrysof IQ Restor (2 eyes), AcrySof IQ PanOptix (2 eyes) IOLs with the mean IOL power of 20,5D (range 2 to 32 D). A short telephonic questionnaire was used to evaluate the incidence of negative and positive dysphotopsia between 2 and 4 months after surgery.


Eighty two patients (86%) were satisfied with the quality of vision, 5 patients (5%) were dissatisfied and 8 patients (8%) were neutral. Positive dysphotopsia and/or glare were reported by 57 patients (60%). In 27 patients (28%) the symptoms were bothersome and 3 of them were implanted with multifocal IOLs. Negative dysphotopsia was reported by 19 patients (20%), and in 2 patients (2%) the symptoms were bothersome. Ten patients counselled the eye doctor and 9 patients did not spontaneously complain about negative dysphotopsia. None of patients required additional treatment of positive or negative dysphotopsia.


Negative and positive dysphotopsia are frequent side-effects after uncomplicated cataract surgery and the incidence of dysphotopsia is usually underestimated. Because all our patients were able to cope with the symptoms, we believe that counselling and reassurance are the important strategies, that facilitate neuroadaptation and help to avoid additional surgery.
