Hi all

I'm sorry for my  English . I had Femtolasik 8 month ago I  and since then I can not see motion and I have dizzyness. I was with many eye doctors and everyone says it's good I did research : OCT , Air puff , pachymetry , then I thought something was up with my head and I was in the hospital  I did research : MRI head , RTG lungs , USG neck and lymph nodes ,blood exam ANA1 ,RF and many others. Everyone doctor  says it's good. doctor says that lasik could not do it but one day after lasik I cant see motion This is so e.g drawer open or closed  not motion

I was right : -1,25 cyl 1,75 ax 175 I was left : - 2.2 cyl -4,25  ax 175 My doctor never hear cant see motion and dizzyness after lasik . My ask Have you ever hear about  symptoms after lasik ?


Original Post

You may have a micro strabismus. This would easily be overlooked by an examining doctor both pre-LASIK and post-LASIK. The LASIK may have exacerbated the situation. You should seek an eye doctor who is most knowledgable about strabismus. The fact that you did not have symptoms pre-LASIK means you (1) were adapted or (2) experienced an alteration in the way your two eyes now are struggling to work together.

Thank you very much for your response I have not written before but when I look closely at the finger, I think I see it with a double. Plus, when I'm sitting at the computer, I can feel tinnitus. I did the test, I did not sit at the computer all day and I cant feel tinnitus.. Is the ear connected in some way with the eye? Thank you very much for your answer

The eyes and "inner" ear work together to help our brain differentiate when objects in our view have changed position or when it is our head or body that has turned. The causes of tinnitus are usually obscure and I know of no connection between tinnitus and ocular coordination.

I need some clarification on how you are writing the prescription. Generally we write the "sphere" first followed by the "cylinder" and the "axis." In the above post you wrote -0.25 cyl +1.00 ax 127. I assume you are meaning +1.00 sphere with -0.25 cylinder at axis 127. Unless you mean -0.25 sphere with +1.00 cylinder. I need you to clear up the nomenclature for this AS WELL AS the pre-LASIK prescription. Getting the plusses and minuses right is very important also.

If you are not sure, ask your doctor to clarify re-write the prescription with sphere first, then cylinder and then axis.

Prior to LASIK: Right Eye -1.25 + 1.75 ax 175. Left eye: -2.25 +4.25 ax 175.

Prior to LASIK you had a fair amount of astigmatism (cylinder) in your right eye but more than double that amount in your left eye. I suspect that, since you often went without glasses for reading, that you SUPPRESSED the image from your left eye, meaning your visual system ignored that eye. This suggests you may have had a long time defect in your binocularity (how the two eyes work together) that would not necessarily have improved much by wearing glasses. 

Since having LASIK the astigmatism (cylinder) has been reduced and is now almost equal between the two eyes. It is more difficult now for your brain to ignore the left eye and this has disturbed your previous adaptation. In other words, while the LASIK reduced and balanced your prescription overall it altered how your two eyes work together.

Will this go away? I don't know. Because it's more difficult for your brain to ignore the left eye now, it is straining to see. One way to help this is to wear GLASSES with your new prescription. Your new prescription cylinder is almost balanced but the SPHERE is almost a full diopter IMBALANCED. Your brain is struggling to make the two eyes work together while, at the same time, it is having trouble ignoring the left eye, which was your custom.

I know this is not what you want to hear but you should wear glasses with the new prescription and see if your symptoms go away. You will need to wear them full time; that is, for distance and for reading or when you are using the computer. You need to train your two eyes to work together. 

Your doctor will probably disagree with (or not even understand) my assessment because you paid money to NOT have to wear glasses. But you now have about a full diopter (0.87) of spherical imbalance between you two eyes. Not correcting this imbalance is like trying to walk with one of your shoes unlaced: You can walk but it's awkward.

I'm sorry I spoiled a little :

Before lasik: 

Eye left (PWR/SPH)    -2.2    cylinder -4.25  (toric)  axis 175

Eye right  (PWR/SPH)  -1.25   cylinder - 1.75 (toric) axis 175

After lasik: 

Eye left (PWR/SPH)    -0.25   cylinder+1.00 (toric)  axis 127

Eye right  (PWR/SPH)  -1.00  cylinder +0.75 (toric) axis 90

I've always had glasses minus a I never wore glasses +



Okay. You always wore glasses before LASIK. That's logical.

Because the difference in prescription between the right and left eyes pre-LASIK was significant, you may have had a binocularity issue but you were ADAPTED to it. That underlying binocularity issue may NOW manifest as the symptoms you are describing. LASIK altered your previous adaptation and created a new situation for you.

Here's an analogy: Let's say you were forced your entire life to wear your shoes on the wrong feet. Throughout the years you adapted and didn't have any problem walking that way. Now someone comes along and tells you to wear your shoes on the proper feet. Both shoes fit but THIS is now awkward and nothing at all like you're accustomed.

You've now been wearing those shoes on the proper feet for over eight months but still are having trouble walking. You show me your new shoes and I say, "Oh, look. Those shoes are not laced. You would have a better chance of wearing those new shoes if they were properly laced."

Hopefully post-LASIK glasses are the "laces" you need to see better as you have almost a full diopter of imbalance between the two eyes. Glasses are certainly the EASIEST thing to try right now.

Thank you very much for your response I have a problem with the amsler grid. When I look at it, the lines change color from black to purple and green andif i stared too long and the whole grid vibrated a little and was hard to focus on. then a terrible afterimage and dizzy

The question was - Why are you looking at an Amsler grid?

Let me rephrase the question - Why are you wasting my time asking me a question about a test (1) that you have improperly administered (hence, a meaningless result) and (2) that is not even indicated in your case?"

There are two non-exclusive answers to the rephrased question:

(1) You believe that reading alone confers comprehension of subject matter for which you have not been trained.

(2) Your pursuit of an answer is more gratifying than actually achieving a solution. 

The former is certainly correct but I am very concerned about the latter being the case as well. Throughout this dialogue you have consistently asked non-relevant questions based on your "research" but have you taken the time to get a pair of glasses that, based on the information you have provided, is a reasonable consideration?

If your "research" (and self-reliance) is so dependable then why did you have LASIK, with its clear risk to patients' visual well-being, in the first place? You signed an IC (informed consent) agreement prior to LASIK, did you not?

Solutions to LASIK complications are not always complicated but must be individualized to the patient, making generic solutions generally inapplicable.

I have forty years in practice and have been providing online advice to LASIK patients for almost twenty years. I have consulted thousands of LASIK patients. The fact that my advice to all is given freely does not INVALIDATE my knowledge or my experience.

Part of all I'm sorry for my English again is my next update. After a few vistts of ophthalmologists, optic neurologists
in the end, one  ophthalmologist  found something


""You may have a micro strabismus. This would easily be overlooked by an examining doctor both pre-LASIK and post-LASIK. The LASIK may have exacerbated the situation.

During a visit to this ophthalmologist, he asked me how many years I have been treated for a squint 

I was very surprised and told him that I had never been treated for a squint

and he was surprised

His diagnosis: 

manifest squint , exotropia, total lack of convergence

these were quick tests, and tomorrow I will go for a big test, so I will do a bigger upload, but I'm happy that there is any chance
