Frequently Asked Questions on Sarkari Medical Boards
Is LASIK or laser eye surgery permitted for RRB Assistant Loco Pilot (ALP)?
No. Laser refractive eye surgery (LASIK, SMILE, PRK, or ICL) is strictly banned for Medical Category A-1 under Indian Railway Medical Manual (IRMM) Para 512. Slit-lamp examinations and corneal topography detect corneal thinning and scars. However, LASIK is permitted for Category C-1 and C-2 non-running clerical or workshop posts if done after age 20 with stable vision.
Can candidates with color blindness get selected in government jobs?
Color vision is strictly tested using Ishihara 24/38 plates. Candidates with red-green color deficiency cannot join safety-critical posts (Train Drivers, Station Masters, Armed Police, Pilots). However, major civilian departments (SSC CGL Assistant Section Officer, Income Tax Inspector, Banking PO/Clerk, Railway Clerks) do not require color vision and admit color-blind candidates.
How do police boards test for Knock Knees and Flat Feet?
Knock knees are checked by having candidates stand straight with inner ankle bones touching. If knees overlap or touch with ankles separated by more than 5 cm, the candidate is failed. Flat foot is tested via the wet footprint test on paper; a flat imprint without an inner arch gap leads to rejection due to injury risk during endurance marches.
What is the procedure to appeal an "Unfit" medical memo?
Candidates must submit an appeal within 21 calendar days of receiving the rejection memo. You must be examined by a Government District Civil Surgeon / CMO who issues a fitness certificate specifically countering the rejection cause. Submit this certificate along with a written petition and the requisite fee (₹1,000 DD for Railways) to the Principal Chief Medical Director (PCMD) to convene an Appellate Medical Board.
