double vision for green lights

Postby noodles » Sat Dec 01, 2007 7:31 pm

You specifically mentioned green lights. I am 9 months out of lasik and still having double vision in left eye. Have dry eyes and started restasis 1 1/2 - 2 months ago so haven't reached full effectiveness. I do notice that green lights (traffic signals, clocks with green digital numbers) are the worst and at times I see the red and yellow traffic lights with less doubling than the green. I am 41 and have worn contacts for about 20 years before lasik. Did you read or hear something about that as an indicator to eyes still getting used to focussing. I'm trying to consider an enhancement and would like to avoid it at all costs, however, not sure I can live with double vision forever. Do you think my eyes could still adjust?

G’day noodles – I haven’t read it anywhere and in fact haven’t been able to find out much more about it. I told my doc that I could focus on red traffic lights quite well but not green lights. It’s really weird actually the green light seems to elongate and turns football shaped.

It’s more noticeable on the new traffic lights we have here in Aus – they are made up of 50 odd individual led’s clustered together so when you get close enough you can see the individual points of light. I’m still having the same issues. For me, the elongation sometimes actually ‘grows’ as I’m watching it indicating my focus going further out of range I guess. It’s a pest...

Doc said that it’s a common test that can indicate if people are having acuity / accommodation / focusing problems. He didn’t elaborate that much but from what I gather it’s easier to see some colours than others depending if you’re myopic or hyperopic.

The easiest way to check if this is your problem would be to compare manifest refraction with cycloplegic refraction. I have approximately 1 full dioptre difference between the two in my offending eye (+0.5 cycloplegic and -0.5 manifest) which still varies daily. Some days I think I’m finally getting used to it then its back down hill for another couple of days.

I’m pretty sure this type of issue would be unique to ‘younger’ hyperopes.

Anyway, It’s a quick and easy way to rule one more thing out at least!

I have had this issue with the green lights since I had my initial customvue lasik back in June 06.
During the day it eventually got better after about 9 months, but still notice it at night (and still sometimes during the day) and VCR clock and other backgrounds at times.
I have residual astigmatism and some HOA's along with some other things post lasik.
I wasn't getting the right answers from my original surgeon, so I escalated it and went to a top refractive surgeon who shed light on it.
Go see a Top refractive surgeon along with a corneal specialist - Then you can make an informed decision on an enhancement or not.
I will be revisiting with him sometime next year and decide on the enhancement.
Let us know what they tell you and what you decide to do.
