Are you bored of your glasses? You can reduce the use of the spectacles or contacts by going through with Lasik surgery. This corrective can even allow you to stop using them permanently.

It uses specific parameters of treatment for different patients. Even though this type of treatment is the most popular, it has the potential for side effects like glare, halos, and night vision - side effects not found in the other types.

Along with the technology of the conventional technique this procedure type enables even further details to be incorporated into the procedure. The curvature and thickness of the cornea is measured and an application of laser technology is used in the corneal periphery. Most of all, it has been rated much higher than the former Lasik type by eliminating the shortcomings.
Finally, the a wave-front guided surgery is available. It is also sometimes called Custom Lasik or Wave-front Lasik. It is the same as the conventional laser treatment, with one exception. In this process severe irregularities in the optical system of a patient can be identified beforehand. It is done using specialized wavefront mapping.
