Laser eye surgery has progressed by leaps and bounds since the very first procedures in the late 1980s. LASIK, LASEK, PRK, SMILE: these acronyms describe different techniques for laser eye surgery.
Read on to find out more.
LASIK is performed using a suction ring applied to the eye to secure it for the creation of a thin corneal flap on the top of the cornea with a femtosecond laser. The excimer laser is then applied under the flap to re-shape the cornea following which the flap is re-positioned.
Visual recovery after LASIK is quick, with minimal discomfort.
With the Schwind Amaris 1050RS laser used by Daniel Gore at Moorfields Eye Hospital, the laser can remove the epithelium and reshape the underlying cornea in one step. This technique is called TransPRK. It is sometimes referred to a ‘no touch’ laser surgery – with no scraping, cutting or peeling of the cornea, the only thing to touch your cornea is the laser light.
Visual recovery after TransPRK is slower compared with LASIK, and the first 24 hours can be painful.
This is a more recent development in laser vision correction in which a femtosecond laser cuts a sliver (lenticule) of tissue within the cornea. This lenticule is then removed by the surgeon through a small key-hole incision. SMILE is a relatively new procedure; there are currently a number of surgical limitations meaning that for the time being Daniel Gore doesn’t not offer this treatment.
