Ophthalmology's dirty little secret
This site does not provide medical advice. I am a patient sharing my personal experiences. Do not make any medical decisions based solely on what you read on this site. If you are unsure about your cataract prospective surgery, interview more than one surgeon and make any medical decisions based on those interviews alone. If you wish to ask a question, please join the Facebook Dysphotopsia discussion in the Dysphotopsia Facebook Group.
Dysphotopsia is preventable
Dysphotopsia is a preventable side effect of cataract surgery. Dysphotopsia prevention is a simple as having the correct size and type of intraocular lens (IOL).
Every year hundreds of thousands of people undergo cataract surgery. Many patients experience difficulties with this surgery. One possible side effect of the surgery is dysphotopsia. A good description of dysphotopsia can be found at Living Healthy 360. One of the more common descriptions of negative dysphotopsia is that patients feel like they are wearing horse blinders. Being a photographer, my description of dysphotopsia is like using a large format camera that has a small format lens on it. The result is vignetting around the edges. Dysphotopsia is described as occurring in two types. Negative dysphotopsia is described as the most common where the edges visible to the patient are dark. Positive dysphotopsia is described as being light or white.
Unfortunately, dyphotopsia seems to be under reported, poorly documented, and not adequately researched. As a result, the number of dysphotopsia case estimates vary tremendously.
