Under dark conditions, the IOL optical surfacedirectly below the PI hole was observed in the right eye, whereas the PI hole overlapped the IOL edge in the left eye, Video images during surgery. On June 3, I went to see a musical with bright lights and noticed a distinct ray coming out from 2 oclock down to 8. Dr. Kieval believes there are more patients affected by these dysphotopsias than are reported, mainly because its not typically asked about during the follow-up visits. I went to see my ophthalmologist who fit me in did all the test said everything looked perfect and shrugged his shoulder. Dr. Masket attributes positive dysphotopsias increase during the 1990s to three factors. 2018 Jan;44(1):6-16. doi: 10.1016/j.jcrs.2017.10.038. Furthermore, its essential that patients understand that dysphotopsia will likely not go away entirely and if it bothers them they should find a solution. Ring-shaped dysphotopsia associated with posterior chamber phakic implantable collamer lenses with a central hole. Positive dysphotopsiathe unwanted images including rings, arcs, and central flashes that become bothersome after IOL implantationhave been associated with everything from the patient's ability to recognize the edge of the implanted IOL to corneal disease to multifocal IOLs to an oversized peripheral iridotomy (PI) that allows too much light sc. Resulted in minimal dysphotopsia post-operatively, in agreement with FDA clinical trial findings.

Dysphotopsia or flashes in the edge of the vision, can occur after cataract surgery. Video games have previously been effective in promoting neuroplasticity and recovering visual acuity. For my part, Id say that since your surgery was just 5-6 weeks there may still be fibrosis occurring with lens and neuroadaptation taking place that will allow your symptoms to settle and streaks to be no longer noticeable. However, for some individuals their symptoms persist and require treatment; usually due to light interaction with an intraocular lens implanted in their eye causing distracting visual phenomena. Undesired light images associated with ovoid intraocular lenses. PubMed Simpson MJ. J Cataract Refract Surg. My surgeon says it could be loose zonules but it would not cause the pulsating vision so it is a separate issue from the PD. J Cataract Refract Surg. J Cataract Refract Surg.

Positive Dysphotopsia. The doctor blows off the issue. For PD from initial acrylic IOLs, exchanging with a silicone versus copolymer IOL yielded similar success rates (87% versus 88%). I usually think about the implant, but you cant forget about the surface of the eye, the iris, and the capsule, he said. Patients suffering from dysphotopsia often report seeing light-based phenomena after cataract surgery, including halos, starbursts and streaks. Iris defects can lead to glare and/or halo that can result in positive dysphotopsia. Simple under- or overcorrection can also lead to the unwanted aberrations, although this can be managed with spectacles, he said. Manasseh GSL, Pritchard EWJ, Rothwell AEJ, Luck J. Acta Ophthalmol.

In the videos I did it looks like my lens is moving but I think its catching light on the edge and rings of the square edge lens and makes it look like its moving. The primary study outcome was resolution or improvement of PD symptoms within 3 months after surgical intervention via IOL exchange. Positive Dysphotopsia after Cataract Surgery. PD seems to be related more to IOL material and design unlike ND that seems to be more associated with physical position of the optic. Included patients reported light arcs, light streaks, shimmering, flickering, halos, and non-concentric starbursts present for more than 1 month. Also mentions that negative dysphotopsia may be have a central neuroadaptive process. Intraocular lens exchange in patients with negative dysphotopsia symptoms. The PI hole in the right eye was covered by the optics of the IOL, whereas the edge of the IOL overlapped the center of the PI hole in the left eye. The PI hole was closed, and the IOL edge is, MeSH 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. Positive dysphotopsia after intrascleral intraocular lens fixation: a Included patients volunteered their PD symptoms; there was no questionnaire to screen for PD, which is usually underreported,8 potentially introducing sampling bias. Adre, E., Tonk, R. Positive and Negative Dysphotopsias: Causes, Prevention, and Best Strategies for Treatment. Retrospective study of 95 patients examining the incidence of ND. Overall, incidence of positive and negative dysphotopsia (ND, a temporal dark crescent- shaped or linear shadow) has been estimated at 49% in the immediate postoperative period, decreasing to 0.22.2% over 12 months postoperatively.2,4,5 This is generally thought to be an underestimation, as patients frequently will not report PD symptoms unless directly asked.6 Additionally, objective evaluation of PD remains elusive, due to a lack of tools to quantify its impact on visual function.

Recently, an effort by the American Academy of Ophthalmology, FDA and IOL manufacturing companies came together to form a collaboration and formulate a questionnaire designed to assess dysphotopsia post cataract surgery with the intention of identifying factors contributing to its occurrence and ultimately decreasing it. Dysphotopsia can often be treated easily. A PI hole created during intrascleral IOL fixation may cause postoperative positive dysphotopsia depending on the position of the IOL edge. Summary of findings regarding positive and negative dysphotopsias in addition to recent surgical management findings. I spoke and described my problem to him last night and both of these highly trained idiots (holding back what I really think of them) acted like they never heard of this problem before.
