i was in the same condition as yours

I had my initial class 1 medical examination today and it did not go as well as I was hoping. We went through my medical history and I had anemia, iron deficiency and hemoglobin deficiency as a child. These were between the ages of 2 and 8, so 6 years of my life. In the space of 11 years, there has been no sign of anemia and the deficiencies. However, the AME would like me to get a full blood test with the analysis and I need to see a specialist regarding a hemoglobin test. However, this is currently looking positive as there were no signs of the medical problems during my blood test performed on the day.

Now the real problem is, although I wear glasses, and I know that since my first optician's eye test that my eyesight is and has been greater than 20/20, I have a slight issue with my hyperphoria. When the optometrist was performing my eye test for the Class 1 Medical, my hyperphoria (vertical eye separation) was 4.0 diopters and the maximum to pass is 2.0 diopters, so essentially I didn't pass the eye test, to say this is really disappointing is an understatement as I would've never expected this to be a problem. I spoke to the optometrist regarding this and I can appeal this, and they recommended I do.

Then I went back to speak to the AME, my next step is to complete the hemoglobin and blood test and send the results to the AME, and if those come back as a pass, I can make the appeal for my class 1 medical. Now I have never had double vision and I notice no difference between both eyes regarding the vertical difference. I don't want to give up on my goal to become a commercial airline pilot, however, I don't want to go through the whole training process and the expense to have a restriction on my class 1 medical that airlines won't accept. When I was speaking to the AME the talk about settling in for a class 2 did come up, but I don't want to throw in the towel, I was told there is a possibility of still getting a class 1 medical, it may require more tests, there was even talk on a possible option where I could continue flying and if I feel comfortable and the CAA agree (I'm sure there is more to it that I don't know as of yet) I may still be issued my class 1. I currently have 8 flying hours and the money I've spent already is not a issue as I've enjoyed every second of it.

I'm currently in a tricky situation, I searched up a little about hyperphoria and the CAA Class 1 but there's not much to it regarding a post on PPRuNe from 2005 and this from the CAA Guidance, where the 4 dioptres are at 6 meters.

h) HeterophoriaApplicants with a heterophoria (imbalance of the ocular muscles) exceeding:
(1) At 6
metres:
2.0 prism dioptres in hyperphoria,
10.0 prism dioptres in esophoria,
8.0 prism dioptres in exophoria;
and
(2) At 33
centimetres:
1.0 prism dioptre in hyperphoria,
8.0 prism dioptres in esophoria,
12.0 prism dioptres in exophoria
should be assessed as unfit. The applicant should be reviewed by an ophthalmologist and if the fusional reserves are sufficient to prevent asthenopia and diplopia a fit assessment may be considered.

Would I have a chance of receiving my class 1 medical, or am I just wasting my time?

Thanks,
Chak.
Hey i was in the same situation as yours, failed the medical due to the phoria. I have 3 diopters of hyperphoria the limit is 2, and on top of that i have 35 diopters of exophoria at near (the limit for near is 12) and 20 at distance (the limit for distance is 8). So as you can see im wayyyyyy out the limits, but i appealed to the CAA for a secondary review. After 6 months i got a letter from the CAA stating that im fit to fly because i have a strong prism fusion range so i dont have double vision (wich is the risk), the fresh class 1 medical was in the same letter btw.

So if you dont have double vision my advice is that you should elaborate your case well and than appeal to the CAA. They are flexible with phorias if you dont have double vision.

Good news is that my blood test came back normal, no abnormalities in my blood, no traces of anemia or iron deficiency. The report is ready to be picked up tomorrow and I will be sending that to the AME as soon as possible. On track so far.

Hey Abbas,

This was a reply I was hoping for, someone who was in a near enough exact position as me, alongside making an appeal/review and everything working out fine in the end. 6 months is a long time to wait for the reply, but the wait was definitely worth the good news. I'm hoping to send the required reports which were asked by my AME, and hopefully, we get the secondary review process started.

Thanks.

Glad that my response was helpful. As for me i was in even worse condition than yours, my AME told me that according to him gaining a class 1 was impossible for me and the best thing to do was changing career. I was destroyed that day but ive promised to my self that i will not give up, because becoming an airline pilot was my dream since childhood. And yess, the day when i recieved the medical that day i realized that nothing is impossible, if you work hard for something, you will achieve it.

Best of luck with the appeal.

Hello PPRuNe, quick query as the only information i can find on this is Part Med.

With regards to the following ...

AMC1 MED.B.070 d,(5)
  1. If the refractive error is +3.0 to +5.0 or –3.0 to –6.0 dioptres, there is astigmatism or anisometropia of more than 2 dioptres but less than 3 dioptres, a review should be undertaken 5 yearly by an eye specialist.
I've had my Class 1 issued to me 3 years ago by the UK CAA, I have recently transferred it over to the IAA... my only limitation was a VDL restriction however when the IAA reviewed it they decided to apply the RXO restriction as well.

My astigmatism is 2.0 dioptres, surely according the wording above I shouldn't have the RXO limitation?

Very interesting talk about [email protected] eye surgery at White Waltham club last night. Particularly a technique called 'blended vision' whereby you have one eye set to 6/6 distance vision, but a bit of short sight in the other to remove the need for reading glasses in middle age. The argument was that it's good for pilots because you don't have the intermediate distance issue of bifocals or the problem with seeing instruments above the windscreen. One professional pilot there who is also an AME has been given 6/9 uncorrected distance vision in one eye and 6/5 in the other, but can also read small print with her 'short' eye without correction so has an unrestricted medical in her late 50s. All sounded quite encouraging.

Class I Medical Failure

In 1998 I completed so much flight training and then I failed my class I medical.

I understand now that the medical standard for eyesight has been relaxed a little.

The CAA advocate safety but how can it not be OK one year but then OK the next?

Just curious

Cool Refractive Lens Exchange

I recently had an eye exam with one of the [email protected] outfits who said they could restore glasses-free sight by refractive lens exchange - same procedure as for cataracts but inserting a multifocal lens. I checked EASA FCL-Med and the procedure is completely forbidden. As a retired pilot still practising as a part-time instructor, it's not the end of the world for me but it might be relevant to younger colleagues. I know that our now defunct CAA Medical Department was notoriously conservative with 'new' eye stuff such as contact lenses and varifocals but it does seem to me that allowing a clear lens for cataracts but not a clever one for sight correction is slightly bizarre. I'd be interested to know if anyone else has been down this route.

Smile Hypermetropia concerns

Hi all,

I took a class 1 initial application test in France, which is more restrictive regarding the vision than the EASA's requirements and got rejected. As asked by the french AME, I had a orthoptic assessment done :

My orthoptic assessment says :

Visual acuity : (Refractive test under cycloplegia)
Right Eye : 10/10 with +2.0 dioptres P
Left Eye : 10/10 with +4.5 (-1.0 at 175°) dioptres P

LAF (I don't know what this means so this might be a french acronym) :
Right Eye : Anterior segment with no fluo- particularity
Left Eye : Anterior segment with no fluo- particularity

Tension :
ODG Normal

Optic Fundus :
Right Eye : Optic fundus and peripheria examination with Goldmann's 3 Mirrors glass
Left Eye : Optic fundus and peripheria examination with Goldmann's 3 Mirrors glass

Am I compliant with the EASA Part Med initial application requirements or is the dream over ?

Many thanks

Any recent experience with reactive progressives?

I am using progressive lenses which work really well for me. For glare I am using flip-up polarising lenses - also works really well for me with steam dials. But I realise that polarizing will not work with modern displays, and flip-ups are a PITA. Does anyone have experience/advice on reactive lenses inside aircraft in combination with progressives ? I understand that lens quality is critical for good results with progressives. This has been discussed here in the past, but not recently as far as I can see.


Thanks

I've found they only work in a really bright interior. Depends what you fly, but unless there is a lot of natural light they don't go dark. Also depends what the windscreen material is.... Buy a cheap pair and try it, maybe.

I have been to the examinator and he could not give me the medical class 1 beacause of my vision.

Left eye +5,5 cyl 0,75 axis 33,0
Right eye +1,75

strabisme

Class 1 Initial UK - Retina

I am due to start my PPL in a few months and I have a class 1 medical initial booked in a couple of weeks time.

I recently visited an opticians and they discovered a small tear in the retina inside my right eye. Just got back from a specialist and they have referred me to see a consultant. The hole may not need attention yet but the consultant will know better whether or not it requires [email protected] correction.

So now I have an issue. Does the AME in my class 1 medical check the inside of my eyes? Will this create an issue for me passing my medical? I've heard it is serious if you fail a medical as it does not look good to future employers.

I do have 20/20 (6/6) vision, no colour blindness or any issues with my eyesight apart from requiring glasses/contact lenses.

Even if I pass my medical and will need laseer correction, will I need to declare this and book a check up with an AME?

Thank you for any advice!

Checking the CAA website recently, I noticed that its position on multi-focal lens implants has relaxed. Whereas they were simply not approved before, now they are 'not recommended' (they're still not approved by EASA).

Has anyone had the procedure and survived the post-op exam? How are the potential post-op issues around contrast and glare assessed?

Squint eye - New Zealand Class 1

Hi guys,
I think I tried to post a thread on this but it got deleted - my bad, mods, anxiety level through the roof.

Situation:
I just did my Class 1 Medicals for New Zealand (initial) yesterday. Everything seems to be OK, my eyesight was cleared, I have 6/6 corrected, no issues there. I did, however, have surgery to correct a lazy eye when I was 3 years old, and yes I did declare that on my form. Since then I have not any issues whatsoever with my eyesight, been driving fine and even playing sports to a semi-professional level, competing like crazy as well and living my life normally.

The issue:
NZ Class 1 initials are followed by a special eye exam. In this exam, they detected an exotropia which I have until today just not paid much attention to because of how little it has affected my life. The doctor said that it would have an angle of deviation a little more than what is required, so he's sent me to see an orthoptist as he didn't have the necessary equipment to do what he had to - in this case, he's asked me to do a Fusional Reserve Test and a BSV test.

The questions:

1. Has anyone had this happen to them?
2. What actually happens in these tests?
3. Is this likely to affect my ability to get a Class 1?

Thanks in advance guys, appreciate it lots.

LASIK while flying commercially. Any experiences?

Hi all,

I am an A320 pilot thinking about LASIK surgery. I have both myopia (nearsightedness) and astigmatism, around 2,5 in each eye for each. My prescription has been stable for the last 3-4 years (I am around 30 years old).

Now, has anyone undergone surgery while flying commercialy? AME has advided around a 3-4 week period with your medical taken away from you, but has encouraged me to go for it. Obviously I would be a life-changing procedure for me and I cannot wait to get rid of my glasses.

Any advice? From pilot who have done it or even doctors who can help....

Thank you

In FAA land, making a “Short” and a “Long” eye to let you function without lenses is a Nono.
if you are good at distance, keep doing what you are, because you’re gonna need glasses anyway. If Far vision and Astigmatism is the primary problem, you could consider LASIK, but it might be a better idea to wait until
youre 40 or so, so that your lens stops changing before you make
an irrevocable alteration to your corneas.

I asked my AME a few years ago for advice on this. He explained that your eyesight recovers 90% in 2 days and the following 10% can take up a year. he said the UK CAA would not allow you to fly for that year! Things might have changed but best advice is to seek opinion direct from your Authority.

I went to Specsavers UK and mentioned that I was interested in LASIK surgery. The Optometrist said DON’T, she explained that she, and most of her optometrist course colleagues at Uni, had LASIK and now she can’t drive at night due “star burst” vision.
