LASIK and femtosecond LASIK
LASIK reshapes corneal tissue with an excimer laser after a thin flap is created. A femtosecond laser may be used to create the flap instead of a mechanical microkeratome. The method chosen depends on the cornea, the treatment plan, the surgeon’s judgement and the equipment actually available.
“Blade-free” describes one step; it does not mean risk-free or automatically better for every eye.
Topography-guided treatment and Contoura
Topography-guided treatment uses corneal surface mapping as part of planning. Contoura Vision is a named topography-guided approach, but suitability depends on reliable measurements and clinical assessment. A detailed map is not itself a promise of sharper-than-normal vision.
Ask which platform is used and why the map changes the recommendation for your eyes.
PRK and SMILE are different techniques
PRK treats the corneal surface without creating a LASIK flap; early discomfort and visual recovery can differ from LASIK. SMILE creates a lenticule within the cornea and removes it through a small incision. It has its own eligibility range and enhancement considerations.
Neither technique should be assumed to be offered at a particular clinic until confirmed.
ICL is not a type of LASIK
An implantable collamer lens is placed inside the eye and does not reshape the cornea. Its assessment includes measurements and risks specific to an intraocular procedure. It may be discussed for selected eyes, but it is not an automatic alternative when LASIK is unsuitable.
How to compare options responsibly
Ask what the examination shows, which procedures are genuinely available, why one option is preferred, what risks matter in your case and what follow-up is expected. Compare written estimates with the same billing unit and inclusions.
A complete evaluation may also lead to continued glasses or contact lenses, a delayed decision or no surgery.
