Hi there,
Just wondering if anyone can give me any advice...
I had intralase treatment around 7 months ago for high myopia. One eye has healed fine and has caused no problems. The other eye has significant astigmatism (which is correctable with glasses), and additionally, what I perceive to be rather severe ghosting, esp. with close-up vision and in slightly dim light. I went to all my aftercare appointments and was told I had a great result - which is true in a way, at least for distance vision in good light. But I feel there must be an underlying problem which is causing the poor vision quality issues in one eye - my optometrist mentioned microstriae but refused to elaborate! The ghosting does not go away with glasses, I am now on my third prescription since the surgery, I even tried a soft contact lens on my "bad" eye, all to no avail. I know I should be thankful for not having serious complications like inflammation etc. (and the surgeon gave me a long long speech about how thankful I should be, and that after all I signed the consent form), but anyway, I'm still finding it hard to function in everyday life, esp. at work and also when reading or doing any kind of close-up work. I have been discharged by Optimax as having achieved a very desirable result (almost 20-20 vision), so I will doubtless be considered a success as far as statistics go. But as regards quality of vision (for which the Snellen chart is pretty much useless as I now know), I am most definately not happy! Retreatment for me is not an option, and probably wouldn't address the ghosting issues anyway I guess. Please can anyone tell me, is there a chance that the ghosting will fade/go away even months after treatment? Would it be worth trying a RGP contact lens?
Thanks for any thought/suggestions!

| Nic, Has anyone mentioned to you Higher Order Abberations. These can be induced through surgery and symptons can be that of ghosting. Unfortunately this condition is uncorrectable. It can make your vision distorted or blurred or like you have ghosting. It usually causes night time vision problems i.e., halos, glares, star bursts etc. If you look it up on google it can give you good descriptions etc, although no advice as like i said there is no treatment. You can be tested for this at the clinic - through a special machine. You need to ask for this to be done. Diagnosis can then be given. I have a slight ghosting and always thought it was through my mild astigmatism but i have since discovered that it could be Higher Order Abberations. Although not confirmed yet. Dry eye can also emphasise the issue too. Hope this helps a little.

Nic
I am with you on this, being able to see the 20/20 line is one thing, being able to see it clearly is another.
You can have an OPD-Scan to test for Higher Order Abberations. This is one of the tests that you should have had prior to surgery, where circles of infrared lines are projected on your eye and a series of measurements taken.
I have replied to a post similar to this previously but I don't know how the search functions work on this board. I posted a link to another site that identified what was induced astigmatism, regular astigmatism and Higher Order Abberations. There are not a lot of threads here on this Board yet so a little searching and you will find the post I am referring to.
Warm regards
Ian

Here is the post I was referring to here
Again, your post and a few of the others here highlight the very issue that the measure of success of this surgery is whether you can see the 20/20 line and not how well you can see it - that is the more important measure (that of visual quality vs visual acuity).

| Hello Nic, If you still have problems with one of your eyes please come in to see us for a consultation, there may be more we can do to help. If you send me some more details I can ask a doctor to contact you? Scarlett, It is true that Higher Order Abberations can be induced during surgery, it is also true that some people have these problems before surgery (i.e. naturally occuring). The whole point of Customised Wavefront is that it reduces HOA.
So it is not quite correct to say that HOA cannot be corrected, they can.
Of course it is not possible to guarantee that they are 100% eliminated, but as technology progresses treatment of HOA will improve.
It is also my understanding that significant HOA's are not very common, about 5% of people have this problem naturally.
Therefore Customised Wavefront is not really needed for everyone. We normally offer Optimised Wavefront for all, this does help with night time vision problems. These can be caused by the treatment zone being smaller than your dilated pupil, so that at night the edge of your vision is looking through an uncorrected area, hence halos.
Without going in to full technical details (of which I am unsure) the Optimised Wavefront uses a specialised transition zone at the edge of the treatment which ensures you receive the correct laser dosage to help eliminate these problems. That's not to say that a normal treatment = night time problems, most don't its just optimised wavefront improves results over a standard treatment. I did not have wavefront treatment, and I have large pupils so technically I was at a higher risk of night time vision problems, however my night time vision is perfect (or if it isn't I haven't noticed it) A final point on Wavefront, we don't differentiate in our literature between the 2 different types of Wavefront as the number of treatment options is already quite confusing. We also don't charge extra for customised wavefront (some clinics do) despite the fact that it takes more of the doctors time to prepare the treatment. These Wavefront options are discussed during consultation - you are correct that the OPD-Scan will determine if you have HOA or not, and the surgeon will treat them if required. This is one of the reasons why it is so important to see an experienced doctor at consultation, not just an optom. thanks Nick
