Contoura Vision is the only technology where consistent success beyond 20/20 vision has been achieved in the majority of patients. More than 40% of the patients that were evaluated were able to read one line on the visual acuity chart more than a person with 20/20 vision, and 13.5% could read two additional lines.
LASIK or Lasik (/ ˈ l eɪ s ɪ k /; "laser-assisted in situ keratomileusis"), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism. [1]
The procedure employs a holmium laser to place a ring of concentric laser burns on the cornea between 6 mm and 7 mm in diameter. These burns cause a ring of constriction on the peripheral cornea causing the cornea to steepen making the eye focus better at near. This procedure may regress somewhat over time.

[1] It can be used to help people that simply need reading glasses, and also those who have started to need bifocal or varifocal spectacle correction ...
ReLEx Small incision lenticule extraction (SMILE), second generation of ReLEx Femtosecond lenticule extraction (FLEx), is a form of laser based refractive eye surgery developed by Carl Zeiss Meditec used to correct myopia, and cure astigmatism.
At the time, it was the first laser to use a five-dimensional eye tracker, compensating for both linear and rotational eye movements during the procedure. Clinical studies indicate that patients treated with this laser achieve higher visual performance [23] [24] than with glasses or contact lenses, with some achieving 125% visual acuity. The ...
