Refractive Surgeries: Candidate who have undergone
photo refractive keratotomy (PRK)/ Laser in setu Kearomileusis (LASIK)
may be considered fit for
commissioning in the Air force in all
branches.
Post PRK/LASIK candidates must meet the visual requirements
for the branch as laid down in below
para
The following criteria must be satisfied
prior to selecting post-PRK/LASIK Candidates.
1.
PRK/LASIK surgery should not
have been carried out before the age of 20 years.
2.
The axial length of the eye
should not be more than 25.5 mm as measured by IOL master.
3.
At least 20 months should have
elapsed post umcomplicated stable PRK/ LASIK with no history or evidences of
any complication.
4.
The post PRK/LASIK corneal
thickness as measured by a corneal pachymeter should not less than 450 microns.
5.
Individuals with high
refractive errors (>6D) prior to LASIK are to be excluded.
Radial Keratotomy surgery for correction of
refractive errors is not permitted for any Air Force duties. Candidates having
undergone cataract surgery with or without IOL implants will also be declared
unfit.
OCULAR MUSCLE BALANCE
Individuals with manifest squint are not
acceptable for commissioning.
The assessment of latent squint or
heterophoria in the case of aircrew will be mainly based on the assessment of
the fusion capacity. A strong fusion sense ensures the maintenance of binocular
vision in the face of stress and fatigue. Hence, it is the main criterion for
acceptability.
a. Convergence (as assessed
on RAF rule)
i)
Objective Convergence Average
is from 6.5cm to 8cm. It is poor at 10cm and above.
ii)
Subjective Convergence (SC)
this indicates the end point of binocular vision under the stress of
convergence. If the subjective convergence is more than 10cm beyond the limit
of objective convergence. The fusion capacity is poor. This is specially so
when the objective convergence is 10cm and above.
Disposal after Kerato- refractive
surgery: All personnel undergoing Kerato refractive
surgery (PRK/LASIK/Femto LASIK/ SMILE) would be initially observed in temporary
low medical category A4G4 (T-12).
a)
Thereafter ground duty
personnel may be upgraded to A4G2 (T-12) and aircrew may be upgraded to flying
category A3G2 (T-12), fit to fly under supervision, subject to following
conditions.
i)
The axial length of the eye
should not be more than 26.0 mm as measured by IOL master or equivalent or
equivalent automated non contact interferometry method.
ii)
The corneal thickness post
surgery as measured by a optical corneal pachymetry method should not be less
than 450 microns and normal post refractive corneal topography. This will be
checked at every review postoperatively. Individuals with a corneal thickness
less than 450 microns will not be upgraded to flying categories and will not be
upgraded to A4G1 either.
iii)
Individuals should not have had more than 2 diopter change in
refractive power since the first month postoperative review.
iv)
Review for upgrading such cases
will be done at IAM/ AFCME/ MEC(east) only with the opinion of Sr Adv
ophthalmology or cornea specialist at each review. Upgradation will be subject
to suitable recommendation recommended by the Sr. Adv Ophthalmology/Corneal
specialist.
b)
Further upgradation to full
medical category A1G1/A4G1, provided all the criteria laid down in above are
satisfied and the visual parameters for the branch are maintained. Aircrew will
be reviewed with an executive report with special emphasis on performance
during night flying and NVG use since refractive surgery can degrade contrast
sensitivity under low light conditions.
c)
Kerato Refractive surgery
undertaken by any other method will be dealt with on a case to case basis.
Useful info sir , 💯
