When Is LASIK NOT Suitable?
1. Thin or Irregular Cornea
- Insufficient corneal thickness
- Conditions like keratoconus
- Higher risk of complications after surgery
2. Unstable Vision Prescription
- Frequent changes in glasses number
- Vision should be stable for at least 1 year
3. Severe Dry Eyes
- LASIK may worsen dryness
- Can affect healing and visual quality
4. Very High Refractive Error
- Extreme myopia, hyperopia, or astigmatism
- Alternative procedures may be more suitable
5. Eye Diseases or Conditions
- Glaucoma
- Cataract
- Retinal disorders
These conditions require separate management.
6. Pregnancy or Breastfeeding

Alternatives to LASIK
If LASIK is not suitable, options include:
- PRK (surface laser treatment)

When Should You Consult an Eye Specialist?
- Considering permanent vision correction
- Experiencing vision changes
- History of eye conditions
Final Thoughts
LASIK is a safe and effective procedure for many people, but it is not universally suitable. Factors like corneal health, vision stability, and overall eye condition play a crucial role in determining eligibility.
A comprehensive eye evaluation is essential to decide whether LASIK or an alternative treatment is the best option for achieving clear and safe vision.
