Laser Assisted In Situ Keratomileus (LASIK) is the most widely used laser vision correction procedure in the world. It corrects near-sightedness, far-sightedness and astigmatism.
Since its introduction in 1991, more than 30 million people have benefited from this technique, making LASIK the most popular elective surgery in the world.
The principle behind LASIK is to change the shape of the cornea so that light entering the eye is re-focused on the retina, thereby improving vision.
In the end-to-end laser version of LASIK, the first step is the creation of a thin stromal cap using a FS200 femtosecond laser. This takes about 6 seconds.
Then an EX500 excimer laser is used to correct the existing refractive defect. It takes the EX500 1.4 seconds to effect one diopter's worth of correction. Correcting a 5-diopter myopia takes only 7 seconds.
In case of contraindications, other procedures such as transepithelial PKR (StreamLight) or intraocular lenses may be considered. Your surgeon will guide you through the different options available to you.
