RxSight Adjustable Lens to correct positive dysphotopsia?
Posted , 7 users are following.
I had the J&J IOL implanted in both eyes in Nov 2022. I did receive the toric lense to correct 3D astigmastism (each eye) and my distance vision prior to surgery was +6D (each eye). After surgery, distance needs +.25D each eye and .50D astigmatism correction each eye. However, I was left with pretty bad "positive dysphotopsia" (halos, rings of light, starbursts on headlights and reflections off the edges of the IOL.). All of this mild in low light but severe in dark. 2nd opinion doc says to remove the J&J IOL and place the RxSight adjustable lens and it will correct all of this light distortion I'm experiencing (still 7 months out). Has anyone had any experience using this RxSight lens to correct light distortion (positive dysphotopsia) caused by the first IOL?

i have severe PD with JnJ Symfony. i am going to use clareon to fix this. i got clareon panoptix in the other eye so i could compare the improvement. i am almost 5 years out from Symfony now. good luck!

Are you saying you’ve already tried the clareon to get rid of the PD? And it worked? Who makes the clareon?

yes. alcon makes clareon. it not eliminated but it is like 15% and not noticeable as JnJ.

What J&J IOL did you get? There are a number of them; Tecnis 1, Eyhance, Symfony, Synergy, ...
.
You should have been given a credit card sized card for each of your eyes that identifies the model # and serial # of each lens.

Model ZCU450 Ser 4799442012. No name on the card. Can you tell which J&J I got?

That would be a Tecnis Toric II monofocal lens with a 4.50 D cylinder correction (3.08 D at cornea plane) for astigmatism. The lens is the standard 6 mm in diameter.
.
Normally monofocal lenses do not cause the halos, nor significant starbursts of light. If you are younger with larger pupils monofocals of all brands can have issues with edge reflections.
.
The RxSight LAL is basically a monofocal lens as well, but the power can be adjusted to some degree in the eye. From my knowlege of the LAL lens I am not sure there is much hope it will be any better than what you have now. The astigmatism correction you have is quite large. I am also not sure the LAL can be adjusted to correct that much astigmatism.

the edge glare with JnJ is extremely debilitating as it extends over entire field of vision. the edge glare when it happens on panoptix is restricted to closer to the light source. while unsightly it is not debilitating.

Thank you for this. I am a 67 yr young female, but have very large pupils. The positive dysphotopsia is debilitating. Is there a lens you might recommend to do an exchange? Or an expert in the field? I'm in the midwest but willing to travel to find a solution. Thanks in advance.

Soks has done more research on this issue than I have, and probably could give you better advice. There are some that say a silicone lens is less susceptible to PD, but I am not so sure about that.

If you are near any of these hospitals, they have highly ranked eye centers
University of Iowa
University of Michigan
Cleveland Clinic
If they are too far away, just google search for a "ophthalmology medical school near me."

@julie66167 posted some information on the LAL in this thread:

.
This info says the LAL lens is silicone, and has one sharp edge and one rounded edge on the lens. Both of those features could possibly reduce positive dysphotopsia. The silicone lens is thicker and sits differently in the eye, and the round edge may reduce reflections off the edges. But there are down sides. I believe the silicone material may have issues with clarity over time. And the round edge on the lens may lead to PCO.
