After all, LASIK is a completely elective procedure where we are operating on normal, healthy eyes that simply need either glasses or contact lenses to have the best vision, says Dr. Bert. “So ...
One conspicuous difference between SMILE and LASIK is the size and shape of the corneal incision. In LASIK, the surgeon performs a 270-degree, 20 mm long incision, while in SMILE the so-called "side cap cut", which is the incision through which the surgeon extracts the lenticule, is usually about 4 mm long.

Wavefront-guided LASIK is a variation of LASIK surgery in which, rather than applying a simple correction of only long/short-sightedness and astigmatism (only lower order aberrations as in traditional LASIK), an ophthalmologist applies a spatially varying correction, guiding the computer-controlled excimer laser with measurements from a ...
Recovery time is longer with PRK than with LASIK, though the outcome (after 3 months) is about the same (very good). More recently, customized ablation has been performed with LASIK, LASEK, and PRK. Transepithelial photorefractive keratectomy (TransPRK) is a laser-assisted eye surgery to correct refraction errors of human eye corneas.
Its 10-year data was published as the PERK (Prospective Evaluation of Radial Keratotomy) study, which proved the onset of progressive hyperopia – often found a decade after the original surgery – is due to continued flattening of the central cornea.

The U.S. Air Force approves the use of PRK and LASIK. [24] Since 2000 the USAF has conducted PRK for aviators at the Wilford Hall Medical Center. More airmen were allowed over the years and in 2004 the USAF approved LASIK for aviators, with limits on the type of aircraft they could fly. Then in 2007 those limits were lifted. [25]
In patients requiring only distance vision correction, a conventional mono-focal intraocular lens is placed in both eyes after the clear lens is removed. [1] While distance vision is fine in this, reading glasses are required for near vision. [1] Another method is to correct one eye only for distance vision and the other eye for near vision ...
Post-LASIK ectasia is a condition similar to keratoconus where the cornea starts to bulge forwards at a variable time after LASIK, PRK, or SMILE corneal laser eye surgery. [1] However, the physiological processes of post-LASIK ectasia seem to be different from keratoconus.
