I still do not think the test is appropriate for pilot testing - let it be done in the real world and those that can will and those that can't won't - simple!!
Amen to that!

Why complain? Get you PPL and get class 1 - CAA say many things, not always logical, however what can we do about it?
Out of limits pre op, they say one day maybe with FAA Commerical we give class 1, next time somebody else call they say they don't give - so you never know the exact answer. Just wait, see and try!

But getting the PPL is easiest thing to do to qualify for class 1 medical, if they told you this 100%, then you should have nothing to worry about.

Once you pass CV is not tested again. That, as has been stated previously in this thread, goes for QF as well. It is the CASA who make the pass criteria for the class 1 not QF. In Australia you do not need to worry about the CAD it has nothing to do with us unless advised otherwise.

We do however need to get behind our friends in the UK to have it stopped before it does threaten our shores.

Explanation

Can someone please explain Sphere Cylinder Axis Prism Base
I am long sighted and I have astigmatism in both eyes, but my left eye is the worst one. (Wish I could have an eye implant.. )

In the Sph column this is either + for long sightedness or - for short sightedness
In the Cyl column I have - what does this column mean?
And the Axis what does this column mean?

It talks about diopters on the CAA website that it should not exceed +5 but that astigmatism must not exceed +2. How do I know from my results if I have passed or not?

I would like someone to pm if they can as I am very worried. I have passed a Gatwick CAA 1st Class Medical 4 years ago but my left eye only just passed.

Thanks

Vision deterioration.

I have a question regarding all those of you out there that have finally reached the airline position. Right now, I'm reaching towards the end phase of the ATPLs after which I will start to do the hour building. Ever since I have started the ATPLs, my vision did get worse due to studying a lot but luckily the Class 1 Medical renovation limits have been stretched which basically means I'm on the limits on a certain requirement.

Now my question is, for all of you who have reached the airline RHS, how have you coped with taking care of your eyesight? I mean, there is a lot of studying involved which means a lot of eye-stress. Do most pilots/co-pilots out there wear glasses?

I'm starting to get worried because, not even being 20, if I start to experience these problems now, I don't want to imagine how I will end up in the future....with respect to meeting viision requirements.

ANY advice, suggestion or solution is appreciated.

Thank you.

Hi,

Eyesight can change with age regardless of the fact that you study a lot. At the age of 21-22 it becomes stable. It might change after that but it does not change that much.
I wouldn´t worry about it much.
I have myopia. I started wearing glasses at age 12 with about -0.25 as I grew it became worse until I reached -4.25. I´ve had the same glasses for about 10 years now and it has only changed a bit (maybe -0.25 in these 10 years).

When you study, just look at distant objects once in a while for a minute or so and then continue. Also you can take short breaks to go walk a little bit, that helps.

Best
Arturo

Hey

Its an easy question, and i bet pretty obvious, but i cant find a link to the FAA for there C1 Medical and Vision Requirements? Any help?

I read here on one page that the FAA have lower vision requirements than the CAA, is this true?

If so, do any other states/countries have lower requirements than the CAA/JAA?

Last question is...

I have been having an almost throbing sensation in my left eye for the last few weeks. Its not done nothing to my vision or any other side affects such as head-aches, etc... Doctor says the eye is fine but go to the optician, the optician says check with the doctor but he cant see anything wrong...

Any one ever had this?

Doctor thinks its physcological but i am sure there is a physical sensation of throbing intermitantly once or twice a day...

Easier vision requirements???

I think you would need to be a bit more specific on what you want to be easier.

It's fairly easy to find info if you go to the FAA official website and the JAR FCL 3 to compaire what you are looking for.

I would say easier is the wrong word, different regulations - still you need to be more specific.

Thanks for the reply Arturo. I do tend to do those things you mention in your post whilst spending a lot of time in front of books.

After doing some browsing on the Internet, I came across this Rebuild Your Vision programme, and it seems quite convincing. Is there anyone on here that has tried it or is it all a fraud?

I see what you mean, easier is not really the correct word...

I shall re-phrase...

Year or so ago, failed C1 on Vision, it wasnt good enough to pass, but it was mighty close. So, i was wondering if there are any slightly less stringant medical authoraties or if there are requirements just a little less?

For the above post, i tried one of these vision programmes... Didnt work as far as getting a C1 was concerned as a started it 3 months before...

However, they make you feel more comfertable about with life without glasses/lenses as i can see better in everyday life and read with no correction, however i still cant see well enough to pass a C1...

I would be interested to know if any one has had good luck with these books or courses to improve vision

A Pilot's viewpoint only.


Firstly, I'm sure that eye exercise is of some benefit, but I'm equally sure that it's not very great. The cilia-like suspension of the lens works in the opposite sense to the way most people think it should. Correction for poor near vision is like trying to push a piece of string.


Doctor thinks its physcological but i am sure there is a physical sensation of throbing intermitantly once or twice a day...
Muscular spasms do tend to enter into a cyclic or diurnal pattern.

I wrote a lot about pain in the Extra Ocular muscles, and have just finished on another thread saying how bad Valium is, but I used it to test my theory that my E O muscles were causing weeks of pain. They were, and once I knew what it was, they stopped doing it. Often the mind work like that with spasms.

Taking just 2 or 3 tablets from the doctor, used only as a diagnostic tool, will ensure that your not tempted to take more.

Grrr

Would this be ok for class 1?

Right
Sph = +3.75
Cyl = -0.25
Axis = 90.0

Left
Sph = +0.50
Cyl = -0.25
Axis = 20.0

Thanks.

Post Lasik - Vision Fluctuations

I am seriously considering doing Lasik.

May I please ask how much does vision fluctuate after the operation and how long these fluctuations take? I know that this is a subjective question. I am just after an average. Is night vision an issue?

For those who did it (preferably pilots who had Lasik in the UK) can you please recommend a specialist and place?

Thanks

This will depend on what your prescription is. For small corrections short sighted could be very fast, 1 week, for long sighted my personal experience took 3 months - many days of very much worries, but got there in the end.
Accuvision in London did mine and was excellent.

It varies from person to person - I had lasik in march and gained my Class 1 in June

I wouldnt say i had fluctuations but the astigmatism of 3.75 i had corrected took about a month to settle. Immediately post lasik i had an astigmatism STILL of about 1.5.... but its now between 0.25 and 0.50 for which no glasses would be prescribed.

I had 3 consultations. One with ULTRALASE (£4000) one with OPTICAL EXPRESS (£3500) and finally a family run optician in Bolton called Clough's and had my treatment for £1900 (both eyes total price)

Don't believe all the HYPE that the big companies use to over sell their treatments as there is still no real evidence that you actually benefit from the machines they boast with bells on.

The consultant at Cloughs does his own consultations (the others have technicians who decide if you are suitable or not!!! - comforting eh!)

Night vision for me IMPROVED....

The problems people have reported in the past was due to the fact that no consideration was given to the PUPIL DILATION at night time..... the surgeons used to cut the flap apply the laser and put the flap back....

Then later on at night when the pupil dilated.... it might have dilated larger than the edge of the incision / flap hence the production of HALOS and HAZE where the person could SEE the flap's edge in the form of deflected light...

This was taken into consideration at my consultation and my pupils were measured to 7.5mm at their largest.... my flap was then cut at 8.0mm wide. The result is that I will NEVER see it even in total darkness!

I hope this helps you

Another person from this forum contacted me a while back re laser surgery and has since had it done!

If you need further information about my experiences etc either PM me or reply on this thread

NurseToPilot & tigermagicjohn,

Thanks for your time to reply to my question.

My main concern is whether the fluctuations are so significant that they affect every day life and activities such as driving my car or minor and negligable.

Any personal experience would be greatly appreciated such as pain after the intervention and what you recommend I should do before and after.

Thanks once again

Smile don't hold your breath . . . . . . . .

be nice if it were true!
You know that saying about "with a pinch of salt" . . . . . . ?

Well, you'll need an HGV to carry this particular pinch !


PS - at first sight this might seem a strange comment . . . .

but it was in response to a post containing this link :

which, for reasons best known to the poster, has since been deleted.

The "claim" is that you can be driving NEXT DAY...... obviously its all dependent on each individual..... and in most cases it IS TRUE...

For me however it was the day after next simply because of the size and shape of my flap that was cut it had to have its "hinge" at the nasal aspect rather than at the top.... so to stop gravity affecting the flap and the risk of it possibly sliding down and becoming misaligned i had a non prescription 'bandage' contact lens applied over my flap....

This made my vision 'soggy' because the water / fluds that were on my eye during the surgery had been trapped under it - so protein had built up in the hours after surgery making me feel like i had scum in my eyes!!

However when the contact lens was removed i rinsed my eyes with the drops given post op and my vision was near perfect!

I think the "fluctuations" you mean would have to be a PHYSICAL change in prescription "right in front of your eyes" kind of thing..... this wont happen...

My Astigmatism immediately post op was still 1.50 dioptres - bear in mind there may be oedema (water swelling) in the area causing the front of the eye not to be perfectly in the right place.... over the following week this must have settled as my astigmatism came down to 0.50.

(I only had a residual in my RIGHT eye. MY left eye was totally non prescription therefore the 1.50 diopter astigmatism in the right eye was not noticed as the left eye 'took over' and sort of cancelled out the blurring) so over the weeks of "settling" there were no visible fluctuations)

Now when its tested its usually in the range of 0.25-0.50.... this ISNT a fluctuation but merely a tolerance level between tests.. For example if you had 3 eye tests in 1 hour EVERY single on would have slight variations.

Hope this helps
