Doctors may have a preference between LASEK and LASIK depending on their expertise. (Learn More). The advent of the excimer laser as an instrument for use in reshaping the corneal stroma was a great step forward in refractive surgery. LASIK stands for Laser Assisted In-Situ Keratomileusis. LASIK (engl. Most experts agree that your surgeon's skill and experience, and an accurate evaluation of whether you're a suitable LASIK candidate , are far more critical factors affecting final LASIK outcomes than subtle differences between excimer lasers. Mayo Clinic reports that this risk is extremely rare even with LASIK procedures, making the apparent benefit of LASEK for that reason negligible. The treatments can either be customised or non-customised. In the meantime, a special medicated contact lens bandage is used to protect the eye during healing. After the laser finishes, the surgeon places a soft contact lens on the cornea to act as a bandage. The Acuity Map is then transmitted to the excimer laser.

The same laser and technology are used in both procedures, but with PRK, the outer tissue of the cornea is often discarded instead of folded back and reattached. SMILE directly cuts the tissue because you’ve drawn the cornea into the patient interface; therefore, in theory, you have a more reproducible lenticule removal. The high-energy pulses of ultraviolet light penetrate only a tiny amount of the cornea and have the ability to remove as little as 0.25 microns of tissue at a time. FS-LASIK requires two laser platforms—one for flap creation (femtosecond laser) and another for stromal bed ablation (excimer laser)—which increases the time and cost of the laser procedure. There are several excimer lasers that have been approved by the FDA for use in vision correction surgery performed in the United States, including: STAR S4 IR Excimer Laser System and iDesign Advanced WaveScan Studio System (Johnson & Johnson), Allegretto WAVE Eye-Q Excimer Laser System (Alcon), TECHNOLAS 217Z Zyoptix System for Personalized Vision Correction (Bausch + Lomb), Nidek EC-5000 with Navex Quest customization (Nidek), MEDITEC MEL 80 Excimer Laser System (Zeiss).

Call For Conventional excimer laser refractive surgery versus wavefront‐modified techniques In procedures where the surgeon removes the outer layer of the front of the eye to access the treatment area (photorefractive keratectomy, PRK), there may be little to no difference between conventional and wavefront‐modified techniques in vision improvement one year after surgery (one study). Studies have shown that eye trackers produce better outcomes and decrease LASIK complications compared with past lasers that did not use eye-tracking systems. You can typically return to most normal activities within 24 hours, and vision may even clear up within a few hours after surgery. LASIK takes a few days or less to see clearly while PRK takes about a month.

Excimer lasers have been used since then in operations to correct defective vision. Once the excimer laser has removed corneal tissue, the flap is put back in place, and you are moved into a recovery room for about an hour before you go home. Seit seiner Erfindung in den frühen 1990er Jahren ist LASIK zur beliebtesten Behandlungsmethode von Sehfehlern avanciert. Laser-assisted in-situ keratomileusis, more commonly known as LASIK, uses a femtosecond laser to cut away the top flap of the cornea and fold it back in order to access the stromal tissue at its core.
