8 Months later I have had PRK as I was - 0.75 D with 0.78 D astigmatism.
My vision is not great after PRK I'm 0.0 and 0.5 D Astigmatism as they overcorrected and this took away my good near.
I had the left eye done with a standard BL M60 and the left eye after 5 days has much better vision than the right.
So I can honestly say that I would never recommend the Symony lens to anyone. You will see halos and rings. If your lucky and your brain can tune them out, then awesome. If not, your going to hate the symony.
Anyone needing surgery I would recommend the Femto laser and considering normal lenses with mixed vision one far, and one set for intermediate.
Thank you for the response.
I need another topic lens since my eye is 1.4
In anyone's opinion especially Dr. Hagan
What would be a good choice lens for my other eye?
Aspherical monofocal, Tecnis zkb00, Tecnis monofocal.
I want to look up opinions. I know some people have two different lenses, but it's more uncommon.
I'd like to pick one that would give me the best chance for distance and intermediate.
That's great news about your wife.
I'm debating what to do with second eye. After all the trouble with the right the specialist says the symfony is meant to be paired with a symfony.
Im torn as I'm going through so much that if this surgeon gets it right, it may be worth getting another one as I love close up reading at about 14 inches.
Though a nice aspherical monofocal could work with none of the BS and so what if I need reading glasses.
My gamble us will I have acceptable intermediate vision without needing glasses?
With symfony I know I get better ranges of vision at all distances, but with the potential for a lot of bs refractive errors.
Do I risk it for a lotential better outcome, or do I play it safe?
just checking in. I had 3 tag sessions to get rid of my capsular bag and fragments etc.
Left with large floaters and one that may be hanging on to something. It's acting like a windshield wiper.
Anyway the yag drastically reduced the star bursts. Still left with halos and bad glare.
Dilation drops will take away the majority of issues. If you have a wrinkle in the bag it will not help.
I'm not happy yet with this lens, but I may be able to get it to a tolerable point without a lens exchange.
The specialist told me that laser correction is often needed to ensure good results.
Apparently the lens is 0.5 mm and the natural lens is 4 mm. The lens can move forward or backward and it is impossible to predict thus requiring a laser tweak.
If I were to go back right now, I would not have gotten this lens. We will see if everything resolves and I change my mind.
Right now, I think not enough is known yet for the majority of doctors to put the lens in and deal with the refractive errors and how to fix them.
Monofocals seem like they carry much less risk.
I'm curious if any night vision issues (halos, starbursts, etc) are reduced with smaller pupil size?
I've seen some posts in the past that some eye doctors gave a patient with those issues an Rx for an eyedrop that constricts (undilates) the pupil in the eye to help with that.
Perhaps someone with a Symfony IOL could try to reduce their pupil size temporariy by looking at a flashlight and then before the pupil dilates again, check if the night vision issues are reduced?
Update. After two different opinions on my issues, I think we may have found the problems.
One issue is a wrinkle in the capillary bag that I will have pco to fix.
More interesting and this may help everyone with issues from the symfony lens.
If you have excessive starburst and glare, you may have been left a little nearsighted. I was left -0.5 in my right eye.
Yesterday I was given contacts to try and so far I can say with contacts, a lot of the glare and starburst are much better. They are not gone completely, but they are much better.
So if you are having issues with glare and starburst and wear left lightly nearsighted. There is strong evidence to suggest contacts will help.
In short the symfony lens was designed to use a curve based on achieving 20/20 at far. Like algebra, when the target is not met, the line falls off of the curve. This error can produce refractive errors.
Could that swelling cause a line of light from 10 and 4 o'clock positions?
The drops to shrink my pupil reduce the halos though the light beam does not go away.
My thought would be that a smaller pupil would reduce all errors.
I read an article about placing the IOL slightly towards nasal to reduce these errors. I just wish I knew more on what would cause this new error.
To clarify it is a beam of light on both sides of my eye at 10 and 4 that is visible in day and night. It is present when I use drops to shrink pupil as well.
As of two weeks I'm.-.5 D out and I'm told no astigmatism.
The light is what is driving me nuts. Just curious if there is anything that can be done to fix it or what is causing it.
Thank you for the response. My doctor looked at it and said it was in perfect. When I was on the table they did several measurements.
The problem I had was my eye pressure went to 50 and then my doctor took it down to 14, then it went back up in 30 minutes and he took it down to 3.
He did say the cornea looks like it needs to heal. I'm so confused on if it's the lens or the cornea.
I welcome a second opinion, but no one will look at it until 3 months are up and I'm out of this doctors care.
Had lens rotated and having a new issue I do not understand. Before rotation, I saw halos. After rotation I see halos and all lights day and night, I see a band of light that extends several feet. It is one band of light that is at about 11:00 and 5:00 and will go away if I cover some of the upper left portion of my eye.
I'm only two weeks after the rotation surgery, but really worried as I cannot tolerate this as it is bright and makes watching TV or doing anything at night troublesome. During the day I have Halo's and it is more mild. I'm hopeful someone will know what it is and if something can be done to fix it.
Well my lens is 10 degrees off and doctor said he can rotate it. Anyone know if I'm okay to have it rotated and if that is the right thing to do with this type of lens or is surgery the right thing
Found out lens is off a few degrees and prk may correct it.
I asked because if I look through a small hole I can see one full ring on top and bottom and two additional rings on the top which leads me to believe I have a lens off center. Plus I asked the eye doctor and he replied it was fairly centered. Day time halos on all lights are still not getting better and vision is about 20/30 in corrected eye with slight astigmatism. Brightness sensitivity has not dissipated at all. Everything's seems like it glows.
Someone told me they had lens implanted and it took a good 6 weeks to get better, but they did confirm their lens was centered properly.
What are the symptoms of a lens being off center?
If it gets treated via lasik what happens if the lens is ever exchanged? At close to 42 I am hopeful that I may live long enough for a super duper lens when they become available even though it may be 5-20 years away.
The halos are during the day and around all light sources.
I called for a second opinion, but was told after 90 days as the liability if someone else touches the eye gets confusing. I guess it becomes a mess if the second opinion says the lens is off axis.
I have cataract in my left eye and would just love for one eye to be seeing things well. Even if I could get glasses to correct the right eye astigmatism I'd be happy for a bit.
It's difficult to work with two not great eyes. Hard to read things at a comfortable distance with either eye. Talking about computer use mostly.
Most of my halos and issues are during the day. Any light source including the TV has them. At night, I have starburst, but I have not been out a lot. Kinda waiting for the daytime halos to go away.
Well on day 10 and thinking about getting a second opinion. I seem to be left with some astigmatism as letters on the TV screen pull apart and cast a significant shadow. Also if I put my finger lightly at the top of my eye, my distance vision dramatically increases.
Halos are still there and not going away. The shimmering has slowed down a bunch. I guess this is the eye healing.
So is it still to early to know ifthe astigmatism and halos will go away? I'm hopeful to get a second opinion and try and get some answers. My current doctor just said learn to live with some imperfections.
Thank you for the response. I'm on day 5 and the glare is getting worse. The flickering is getting a little better.
The most troubling thing is white text on a dark background. The letters distort into a shadow like effect. Day 2 after the surgery, this was subtle now it really has a shadow. It seems this goes with the glare getting worse.
I assume I just want to know how it will turn out.
The floaters are predominantly white blood cells and I assume they will be absorbed. I had full FOV and the floaters freaked me out.
I stayed up late reading before the surgery as I could not decide what lens I wanted. Everything I read makes things worse. I had a topic symfony put in, but for 41 years I never wore glasses. I developed floaters had a FOV and was fortunate to have a cataract come on 11 years later. According to what I read is I should have needed glasses.
So thank you for the response.
My question is for anyone with lenses. I can see halos around all led lights, letters on the TV, the TV and all windows. I'm curious how long it was till things got better?
I keep hearing 3 to 6 months, but assume some may have gradually gotten better each day.
For me it seems flickering is slightly better, but no luck with halos, starburst, and glare.
re: "If the floaters were gone, I would be ecstatic with my choice"
The floaters aren't related in any way to the particular choice of IOL model since they are inserted the same way, with only minor variations perhaps in incision size and the instrument used to stick it in. The Symfony is for instance physically the same overall size and shape as the Tecnis monofocal IOL so its inserted the same way. It merely has different optics, just like you might have two people with the same eyeglass frame but different lenses in them.
re: " I seem to vary as sometimes I can read at a comfortable 16-18 and other times I'm at 20-26 to resolve the text. "
As I noted in my posts, my near vision fluctuated for the first couple of days after getting Symfony implants in both eyes, a day apart. Sometimes I could see a computer screen ok, others I needed readers to even see at computer distance. Then by the 3rd day it settled down, and seemed about the same by 1 week when it was tested at 20/25 at best near, and been that ever since. Distance vision was almost at 20/15 at the 1 week postop, now its at least 20/15 (that line is easy and they didn't have a line below). However everyone is different, some people take some weeks or months to get their best near results, the time isn't predictable, and less commonly even the best distance can take some time to come in. Unfortunately neuroadaptation speed varies greatly between people (I tended to wonder if my brain got used to adapting to new optics by having used varied multifocal contacts before cataract surgery) Your brain will continue to neuroadapt for a while, and to learn to tune out initial visual artifacts like halos. Most studies on IOLs don't record their incidence until the 3 or 6 month mark after temporary ones have gone away after the initial healing period, though people who still have halos by then may still see them fade and disappear, but not all. . Most people don't consider halos a problem, a tiny minority do.
re: the flickering. The most likely explanation is that in the initial postop period the lens hasn't yet healed into place and may be jiggling a bit. There are rare other causes, but no reason to consider them unless the issue keeps up, its most likely to resolve so give it a couple of months before worrying, when the initial healing has finished.
You are still in the early healing phase, most people have decent distance vision with any IOL in the first days, but I gather some can take a few days even with a monfocal IOL. In terms of how long
There are many helpful posts on post op Symfony IOLs some as recent as yesterday. You can access them using the search feature and by reviewing topics over the last week.
