what causes positive dysphotopsia after cataract surgery

Patients experiencing vision issues resembling glare, halos or shadows may become frustrated and misunderstand their situation. It is also important to consider that although reported success rates in this study are high, there are inherent risks to IOL exchange including capsular compromise, zonular dehiscence, endophthalmitis, and cystoid macular edema.11,12,13,14 Risk may be influenced by other ocular comorbidities, time since initial cataract surgery, extent of capsular fibrosis, and skill of the surgeon, and it is essential to have an informed discussion of risks and expected benefits weighed against severity of a patients symptoms.

What is the Most Effective Glaucoma Treatment? Dysphotopsia can often be treated easily. Accordingly, we concluded that the abnormal photopic image in the left eye was caused by positive dysphotopsia, in which light passing through the PI hole was reflected by the edge of the IOL. This effect may occur more commonly at night or in artificial environments with low ambient lighting conditions. Contents. ", "Thanks for responding bobbyo!
