hi Vishal, C-TEN is basically just PRK, another variant of surface laser treatment. There can be various reasons for starbursts, and they can be seen in the post-operative period. Typically they do improve with time so you might stick with your surgeon if things are getting better overall. However, if you see no improvement by 4 months, and if your surgeon cannot offer a solution or explanation, you might now wish to seek a second opinion. Thanks Dave

Hi Dave,
I Type this with great concern, my night vision has not improved since i got the C TEN procdure done 4 months back. I still have ‘starbursts’ looking at all types of lights,esp when watching tv. My practitioner does not have a solution to why this is. i took vitamin c and omega-3 for 3 months as adviced. any type of assistance will be greatly appreciated.

hi Clare
Thank you for your message. How long after your procedure? What was your prescription before? Do you know what it is now? Did you see any glare at night pre-op?
thanks, Dave

I have night vision problems after the procedure – light ‘leaking’ out from vehicle brake lights/traffic light signals etc – can this be corrected or is it permanent damage?

Thanks Sharif. Agreed, as night vision problems for us are really a thing of the past. We of course, perform treatment diameters to cover the night pupil area, and advise patients that they may have some night vision effects during the first few weeks. But it is no longer something we think of as an issue we will be dealing with, with patients post-operatively.

Just thought I’d chime in.. I have slightly larger than average pupils, and although I do get some star bursting in very very dark situations, it is nothing that I haven’t gotten used to. This only happens 5% of the time at night if I’m somewhere with absolutely no lighting.

I had halos for a while that were extremely extremely noticeable and looked like someone literally drew a circle around lights at night. Those thankfully completely disappeared within a couple of months. The biggest difference is that my night vision has become 1000% sharper and crisper, which I’m very thankful for.

I had Z-Lasik in the US about 2 weeks ago and since then had realised that there are numerous floaters in my treated eyes.

Would lasik result in floaters and will they ever go away?

hi, We dont offer LASIK to patients with 480 corneas, only PRK. With 8mm pupils, I would want a 7mm optical zone, plus wider blend zone. I suspect you are not a good candidate for laser correction. regards David

Hi,

I have large pupils at night (7.9mm) and the lasik surger optical zone would be 6 and 6.3mm, would I have really bad night vision ? my prescription is -6 and -5.75 with -2.25 astigmatism in each eye (ps. I have no problem at all with night vision with contact lenses).

I also have thin corneas (480microns each) and in my last screening I was told my corneal topography is perfectly normal (one of their machines showed 0% )

Would it be safe for me to have lasik ? that is lasik with intralase laser.

Any advice would be much appreciated.

hi Adam
We have not seen problematic night vision problems with Z-LASIK using the WaveLight excimer laser when treating short-sight, even for pupils up to 9mm. We enlarge the treatment zone to produce a wide ablation, of course. Typically your night vision will be the same as pre-op. As with any surgery there can be risks, so if you are not sure about LASIK then delay having treatment until you feel you are ready to proceed.
Regards, David

I’m very close to signing up for treatment with you, but night vision remains one of my biggest concerns. I know I have a large dilated pupil size, so I presume this is taken into account. If your clinic felt any concern about the treatment area not being big enough, would this have been flagged in advance, or could I be border-line?

Thanks
