IOL Exchange: POSITIVE Dysphotopsia

i have symfony zxr00 16.5. i see the lens edge in dark around street lights other direct or indirect light sources. many times they are arcs in upper nasal direction. i have PCO which has progresses in the last year so as to affect visual acuity. they say lens is centered perfectly. my near vision with symfony is poor so i am waiting on yag or exchange until i decide what to do with my other eye. alphagan works for me and so does lumify.

Restor 2.5D IOL in one eye. Slight cataract in the other eye that does not yet affect my vision. I am 2 years post surgery.

1. I had minor halos around bright light sources immediately after surgery. I expected this, they were small and did not bother me. The intensity and size decreased slightly over a few weeks and then have been consistent for the past two years.
2. I had glare from light sources striking my eye at an angle. This still happens but my brain mostly tunes it out now.
3. I had YAG for PCO on 12/12/2019. I did not notice the PCO but the surgeon told me it was there and I would notice the improvement. I did not notice any improvement to my eyesight but I now see very large and obvious starbursts that are huge. I had none at all before YAG. The surgeon says that this should diminish over time but I have not noticed any reduction since the procedure. I describe them as several (4 to 12) usually thin, shafts of light emanating from the center of a source of light and extending outward. They are of varying lengths but overall pretty long (for example, looking across the street at a light on a house, the rays of light extend out past several neighboring houses - do note that we are in a city and the houses are touching each other).
4. The starbursts really suck and are distracting but I still feel safe driving at night, I just need to concentrate more. Also, counter to what I expected, they are much more of an issue driving in a dark area with only a few cars. Driving in a dense city, the overall light levels are higher and this eliminates many of the starbursts.
5. Starbursts are most intense with only the eye with the IOL open. If I open my other eye too, some of the "lines of light" disappear and I can actually watch them fade out which is kind of interesting, like watching the brain tune out the dysphotopsia.

Tecnis ZKB00 Multifocal (bifocal)

• several concentric halos around lights, several times the diameter of the original light source. Worse with red lights, much worse at night.
• ghost images around any high contrast items, whether 2D (paper) or 3D (objects)
• starbursts with bright lights (headlights), which I had not thought bothered me because I look away. But they do sometimes make oncoming headlights hard to bear.

Bausch & Lomb LI61AO

• starbursts with bright lights
• hazy halo around bright lights, mostly stoplights and red tail lights, a few times the diamter of the original light, sometimes as large as the halos from the multifocal eye. Sometimes with faint concentric circles very close together, sometimes just a haze. Sometimes it has a liquid aspect to it. Sometimes speckly. I can't explain why I have this, and the most specialized optho said my retina is young and sensitive.
• lights are skewed a little, smudged, which the ophthos attribute to a post-surgical astigmatism

Hi. I have the Tecnis ZA9003. I see startbursts from lights, especially at night. I am hoping a YAG procedure will help secondary cataracts and take care of the startbursts. It's becoming unsafe to drive at night.

I also have extreme sensitivity to man-made light sources since the cataract surgeries. I get flickering from refraction and backscatter and can't stay in most stores long.

Doctors have a hard time identifying this stuff because they may not have seen it before and some of it is poorly understood. As far as they can tell, your eyes probably look good.

Pilocarpine does not help me, I am supposed to ditch the glacier goggles and hope for neuro-adaptation within 2-3 years. But, I mostly just hang out at home and am becoming a bit of a shut in due to the terrible terrible light.

I can recommend a great doctor in Salt Lake City, if you are desperate.

Not exactly the same, but since my cataract removal, vitrectomy and epiretinal membrane peel, I experienced a distinct flare at one discrete angle in the affected eye. I later benefited from a capsulotomy and this has cured the problem.
