Quick Answer
Is LASIK allowed in NDA?
| NDA Wing | LASIK / PRK / SMILE Permitted? |
|---|---|
| NDA Army | ✘ NOT permitted — permanent disqualification |
| NDA Navy (NA) | ✔ Yes — with conditions (see below) |
| NDA Air Force Flying | ✔ Yes — with conditions (see below) |
Radial Keratotomy (RK) is permanently disqualifying for ALL wings, including Navy and Air Force.
NDA Army Wing — LASIK Not Allowed
LASIK, PRK, SMILE, and all kerato-refractive procedures are categorically not permitted for the NDA Army wing entry. This is per DGMS (Army) Medical Standards SN 76060/DGMS-5A (01 Aug 2019), vision standards table (page 7).
⚠
Candidates who have undergone LASIK, PRK, SMILE, or any corneal refractive surgery will be found unfit for NDA Army wing entry irrespective of the outcome of the surgery. There is no exception, no appeal waiver, and no minimum post-op waiting period that changes this policy.
This is a firm policy, not a temporary restriction. If you have had LASIK and wish to join the Army, your route changes — you would need to appear via CDS (IMA) after graduation, where different medical standards apply.
NDA Air Force Flying — LASIK Conditions
LASIK is permitted for NDA Air Force Flying entry, but only if every single one of the following eight conditions is satisfied. Failure on any single condition = unfit. There is no partial credit.
Per AFCAT 02/2023 para 28(e) and NDA Annexure C (Air Force Medical Standards):
- 1 Pre-operative refractive error ≤ ±6.0 D — the refractive error documented before surgery must not exceed ±6.0 dioptres (spherical equivalent). If your pre-op power was −7.0 D or higher (in absolute terms), you are unfit even if surgery was perfectly successful.
- 2 Surgery NOT done before age 20 years — the date of surgery must fall on or after your 20th birthday. Surgery performed even one day before your 20th birthday is disqualifying. See Section 6 for detailed age planning.
- 3 Minimum 12 months elapsed post-surgery, with uncomplicated recovery — the Service Medical Board (SMB) date must be at least 12 months after the surgery date. The recovery must have been uncomplicated (no halos, glare, corneal ectasia, or dry eye requiring ongoing treatment).
- 4 Residual refraction ≤ ±1.0 D Sph or Cyl — NIL residual refraction for Pilot and Observer entries. Ground duty Air Force entries may have up to ±1.0 D residual. Check which entry you are applying for.
- 5 Axial length by IOL Master ≤ 26 mm — the axial length (length of the eyeball from front to back) must be 26 millimetres or less, measured using IOL Master biometry. Longer axial length correlates with myopia risk and retinal pathology.
- 6 Central corneal thickness (CCT) by Pachymeter ≥ 450 microns — the cornea must retain at least 450 microns of thickness post-surgery. LASIK removes corneal tissue; insufficient residual thickness risks corneal ectasia and is a safety concern for pilots.
- 7 Normal healthy retina confirmed by retinal examination — a full retinal examination must show no pathology — no retinal tears, detachment, lattice degeneration, or other abnormalities. This is typically done by fundoscopy with pupillary dilation.
- 8 Certificate from medical centre — MANDATORY — a written certificate from the operating medical centre specifying the date of surgery, the type of surgery (LASIK/PRK/SMILE etc.), pre-operative refraction, and post-operative refraction is mandatory. Absence of this certificate results in immediate rejection at the SMB, regardless of all other test results.
Acceptable surgical procedures for Air Force entry: PRK, LASIK, Femto-LASIK, and SMILE.
💡
Tip: Collect your surgery certificate, IOL Master axial length report, pachymeter CCT report, and retinal examination report at the time of surgery and keep them safe. Replacing these years later is difficult and may delay or jeopardise your SMB.
NDA Navy Wing — LASIK Conditions
LASIK is permitted for NDA Navy wing entry under conditions very similar to those for Air Force. The same eight conditions listed above apply. Additionally:
- LASIK is not acceptable for candidates selected for Submarines, Divers, or MARCO (Marine Commandos) — these specialisations require stricter ophthalmological fitness.
- Residual refraction must be NIL for Pilot/Observer entries in the Navy. Up to ±1.0 D is acceptable for non-flying naval entries.
- The same documentation requirements apply: surgery certificate, IOL Master report, pachymeter report, retinal examination report.
ⓘ
Navy wing candidates who opt for Submarines, Diving, or MARCO during training will be re-medically examined. LASIK candidates who pass the initial naval SMB may later be restricted in specialisation assignment.
Radial Keratotomy (RK) — Permanently Unfit for All Wings
Radial Keratotomy (RK) is an older corneal refractive surgery technique that uses a series of radial (spoke-like) incisions in the cornea to flatten it and reduce myopia. It was common in the 1980s–1990s before LASIK was developed.
❌
Radial Keratotomy is permanently disqualifying for ALL NDA wings — Army, Navy, and Air Force. There is no appeal exception. Even if your vision is perfectly corrected and all other parameters are normal, RK is an absolute contra-indication. This applies regardless of when the surgery was performed.
If you are unsure whether you had RK or LASIK (you may have been too young when surgery was performed, or your records are unclear), obtain your original surgical notes. Key distinguishing features: RK leaves radial corneal scars visible under a slit-lamp, while LASIK/SMILE leave a central flap edge or smooth ablation zone.
What If I Already Had LASIK Before Age 20?
Having LASIK before age 20 is a disqualifying condition for both Air Force Flying and Navy entries in NDA. This is an absolute rule — there is no appeal or review mechanism that can override it.
The age-20 requirement exists for two reasons:
- Refractive stability — corneal refractive error typically stabilises around age 18–21. Surgery before the power has stabilised increases the risk of regression, meaning the correction fades and myopia returns. The armed forces cannot risk pilot candidates with unstable vision.
- Long-term predictability — post-LASIK complications such as corneal ectasia are more common when surgery is performed in younger, still-developing eyes.
⚠
If you had LASIK at age 17, 18, or 19, you cannot appear for NDA Air Force Flying or Navy (pilot/observer) entries. Your option within the armed forces is the NDA Army wing (where LASIK is disqualifying anyway) or post-graduation entries via CDS/AFCAT after checking applicable medical standards for those entry schemes.
Practical LASIK Planning Timeline for Aspirants
Understanding the NDA entry timeline helps you plan surgery correctly. Here is a typical journey:
| Phase | Typical Age | What Happens |
|---|---|---|
| Class 12 studies + NDA Prep | 16–18 | Preparing for written exam. Do NOT have LASIK in this phase — you are below age 20. |
| NDA Written Exam | 17–19 | UPSC NDA written exam. Results take 3–5 months. |
| SSB Interview | 18–20 | 5-day SSB process. Recommended dates in stage. |
| Service Medical Board (SMB) | 19–21 | Full medical examination after SSB recommendation. LASIK surgery must be ≥12 months before this date AND you must be ≥20 at surgery date. |
| Academy joining | 20–21 | Joining NDA, Khadakwasla. |
Recommended LASIK planning:
- Have LASIK at age 20 or later — never earlier.
- Plan surgery at least 18 months before your expected SMB date — the 12-month minimum is the absolute floor; 18 months gives buffer for any complications that delay healing.
- Confirm your pre-op refractive error is ≤ ±6.0 D before booking the surgery. Ask the eye surgeon for a written refraction record.
- Collect and preserve all documentation at the time of surgery (see Documentation Checklist below).
- Choose a reputable ophthalmology centre that provides detailed post-op reports — military SMBs require specific measurements (IOL Master, Pachymeter) that not every clinic provides.
✓
Best-case scenario: Turn 20, undergo LASIK with full documentation, wait 18 months, appear for SMB with all reports. This is the safest planning path for Air Force Flying aspirants.
Documentation Checklist for LASIK Candidates at SMB
Candidates who have undergone LASIK, PRK, Femto-LASIK, or SMILE must bring all of the following documents to the Service Medical Board:
- Surgery certificate from the medical centre — must specify: (a) date of surgery, (b) type of surgery (LASIK / PRK / Femto-LASIK / SMILE), (c) pre-operative refraction (both eyes), (d) post-operative refraction (both eyes).
- IOL Master axial length report — biometric measurement of the axial length of each eye (must be ≤26 mm).
- Pachymeter central corneal thickness (CCT) report — ultrasound or optical pachymeter measurement (must be ≥450 microns post-surgery).
- Retinal examination report — fundoscopy or indirect ophthalmoscopy report confirming normal, healthy retina with no pathology.
⚠
The surgery certificate alone is not sufficient. All four documents are required. A missing IOL Master report or Pachymeter report is a reason for rejection at the SMB even if your vision tests are perfect on the day.
Frequently Asked Questions
Is LASIK allowed in NDA?
It depends on the wing. LASIK is NOT allowed for the NDA Army wing under any circumstances — candidates who have had any kerato-refractive surgery are found unfit for Army entry per DGMS (Army) Medical Standards. LASIK IS allowed for NDA Air Force Flying and NDA Navy entries, but only when all eight conditions are satisfied: age ≥20 at surgery, minimum 12 months post-op, pre-op refraction ≤±6.0 D, residual refraction NIL (for pilot/observer) or ≤±1.0 D, axial length ≤26 mm, corneal thickness ≥450 microns, normal retina, and a valid surgery certificate.
Is LASIK allowed for NDA Air Force Flying?
Yes, provided all conditions are met. Acceptable procedures include PRK, LASIK, Femto-LASIK, and SMILE. The candidate must have been at least 20 years old at the time of surgery, at least 12 months must have passed since surgery, the pre-operative refractive error must have been ≤±6.0 D, residual refraction must be NIL for Pilot/Observer entries, axial length must be ≤26 mm, central corneal thickness ≥450 microns, retina must be normal, and a surgery certificate from the medical centre is mandatory.
Is LASIK allowed for NDA Army wing?
No. LASIK, PRK, SMILE, and all kerato-refractive procedures are NOT permitted for NDA Army wing. This is a firm policy per DGMS (Army) Medical Standards SN 76060/DGMS-5A (01 Aug 2019). There are no exceptions based on surgical outcome, waiting period, or current visual acuity.
Is LASIK allowed for NDA Navy wing?
Yes, with conditions similar to Air Force — age ≥20, 12 months post-op, pre-op refraction ≤±6.0 D, normal retina, and complete documentation. However, LASIK is NOT acceptable for candidates assigned to Submarines, Divers, or MARCO. Residual refraction must be NIL for Pilot/Observer entries in the Navy.
How long after LASIK can I appear for NDA medical?
A minimum of 12 months must have elapsed from the date of surgery to the date of your Service Medical Board (SMB). This is a hard minimum — you cannot appear even one day before the 12-month mark. It is strongly recommended to wait 18 months to allow buffer for any delayed healing or complications that could affect test measurements.
What is the minimum age for LASIK for NDA?
20 years. Surgery performed before your 20th birthday is disqualifying for NDA Air Force Flying and Navy entries. This rule applies regardless of how successful the surgery was or how much time has passed since. Army wing candidates cannot have LASIK at all regardless of age.
Is SMILE or Femto-LASIK allowed for NDA?
Yes. For NDA Air Force Flying and Navy entries, the procedures accepted include PRK, standard LASIK, Femto-LASIK (blade-free LASIK), and SMILE (Small Incision Lenticule Extraction). All are treated equivalently and all require the same documentation and conditions to be met.
Is Radial Keratotomy (RK) allowed for NDA?
No. Radial Keratotomy is permanently and absolutely disqualifying for ALL NDA wings — Army, Navy, and Air Force — with no exceptions. RK is an older technique using radial corneal incisions that has been largely replaced by LASIK. If you have had RK, you are permanently unfit for all NDA entries regardless of your current visual acuity or any other parameters.
