With standard laser eye surgery the laser treats the surface of the eye (cornea) in a similar way to spectacles or contact lenses. This is considered a ‘one size fits all’ treatment as it does not allow for the unique imperfections on the surface of your eye. Wavefront laser eye surgery however is different, as it takes many precise measurements right across the surface of your eye compared with only one point of your eye in standard laser eye surgery. When the laser is applied it takes into account all these imperfections and corrects them, making for a more accurate laser vision correction. Wavefront is generally recommended for people with high prescriptions (particularly astigmatism) and for those people with large pupils. Wavefront surgery reduces the chance of having night vision problems following laser eye treatment.
Wavefront can be used with both Lasik and Lasek. Find out more in our Wavefront guide.
