If you want to reduce your dependence on glasses, you may hear several names. Here is a plain comparison. Which options are right, and available, depends on a detailed assessment of your eyes.
| Procedure | How it works | Often suits | Recovery |
|---|---|---|---|
| LASIK | A thin flap is created in the cornea, and a laser reshapes the tissue underneath | Short sight, long sight and astigmatism with healthy, thick enough corneas | Most see well within a day |
| SMILE | A laser shapes a small disc of tissue inside the cornea, removed through a tiny opening | Short sight and astigmatism | Quick, often within a few days |
| PRK | The surface layer is removed and the laser reshapes the cornea, with no flap | Thinner corneas, contact sports, some jobs | Slower, about a week of discomfort, vision settles over weeks |
| ICL | A thin lens is placed inside the eye, in front of the natural lens | High short sight, thin corneas | Quick; the lens can be removed if needed |
