They are most commonly used to correct myopia (nearsightedness) but can also be used to correct hyperopia (farsightedness) and astigmatism. The excimer laser alters the refractive state of the eye by removing tissue from the anterior cornea through a process known as photoablative decomposition.
Which type of laser is excimer laser?
ultraviolet
What is excimer laser for eye?
The excimer laser alters the refractive state of the eye by removing tissue from the anterior cornea through a process known as photoablative decomposition. This process uses ultraviolet energy from the excimer laser to disrupt chemical bonds in the cornea without causing any thermal damage to surrounding tissue.
How much does an excimer laser cost?
The big LASIK laser manufacturers in the United States charge well over $100,000 for an Excimer laser. The typical range is between $150,000 at the low end to nearly $300,000 at the high end.
