Corneal thickness is one of the most critical safety parameters for LASIK. Here is what you need to know if you have been told you have a thin cornea or a disqualifying condition.
Minimum Corneal Thickness for LASIK
Standard LASIK requires a minimum pre-operative corneal thickness of 480–500 microns. At least 250–300 microns of corneal stroma must remain after treatment to maintain structural integrity.
Options for Thin Corneas
- SBK Thin-Flap LASIK: Creates a thinner flap (90–100 microns), preserving more corneal tissue
- ReLEx SMILE / SMILE Pro: No flap required — ideal for thin corneas
- PRK / Trans-PRK: No flap created — suitable for thin corneas but has longer recovery
- ICL (Implantable Collamer Lens): For corneas too thin for any laser procedure
Absolute Contraindications
Keratoconus, uncontrolled glaucoma, severe dry eye syndrome, autoimmune diseases, uncontrolled diabetes, and pregnancy are absolute contraindications for LASIK. Our 90-minute evaluation specifically screens for all these conditions to ensure your safety.
