Lasik eye surgery Belfast is now common thus the need to know the different type of excimer laser that is used in the operation. The excimer laser is the one responsible in reshaping the eye’s cornea and make corrections if there are any refractive errors such as astigmatism, farsightedness and nearsightedness. Excimer lasers are responsible in changing immensely the laser eye surgery by ensuring safer and effective operations. It works by removing microscopic tissue that are embedded in the cornea and this is done with a high level of accuracy to make sure that no damage will be inflicted on the corneal tissue.

In the US, the FDA sets certain safety standards before a technology can be legally used. The same goes in the case of excimer lasers. It must pass certain criteria when it comes to safety and effectiveness. Here are the latest excimer lasers that are used whenever lasik operation is performed:
– Spot Scanning Laser. This is also known as the flying spot laser and considered the most common laser used in lasik eye surgery. This type of laser uses laser beams that are small in diameter about 0.8 to 2 mm. It scans the whole cornea in order to prepare the part to be treated. When this type of method is used, there is a greater possibility of creating the smoothest cornea compared to other methods. When the cornea is the smoothest, much better treatment can be applied and correction of irregular astigmatism will produce a much better result after treatment.
– Slit Scanning Laser. This is called as such because of the presence of slit holes where the small laser beams are attached together with a rotating device. While doing the treatment, the laser scans the slit hole which is capable of enlarging. Smoother treatments are achieved using this method compared to older types of lasers with broad beams. The downside is the risk of overcorrection and decentration when used by an amateur surgeon or if no eye tracker is employed during treatment.
– Wavefront-guided Laser. This is different because it creates a customized lasik treatment for each patient. This type of treatment may also utilized either lasers used in spot scanning or slit scanning.
