The latest generation of Custom Lasik utilizes a series of surgical instruments that personalize the treatment for every patient. Consequently, the treatment for two patients with the same level of myopia will be different because every cornea has a different shape and topography.
The fourth generation Excimer Laser allows for a wider range in the treatment of hyperopia, obtaining corrections of up to +7.00D.
The Excimer Laser uses a combination of argon and fluoride gases that produce a UV radiation with a wavelength of 193 nanometers, considered the most optimum for producing the appropriate biological effect. The radiation is emitted in ultra short pulses of 10 nm. and with a frequency of 50 Hz.
The mixing of the gases that fill the laser cavity determines the wavelength emitted by the laser. To obtain the necessary level of excitement of the gases, an external energy source is needed that allows for the combination of the atoms of the two gases with halogen atoms.
The result is a high-powered UV radiation that causes the rupture of the inter- and intramolecular chains, which in turn, cause the photodecomposition and separation of the organic tissue.
This type of laser achieves a high level of precision and predictability, permanently altering the refractive power of the eye. At the same time, it does not affect the adjacent tissue due to its disintegrating ability that vaporizes only the affected tissue during treatment. There is no risk of scarring in the neighboring tissue, as it has not been affected.
Thanks to the aberrometer and topographer tools, we are able to achieve customized treatment of every cornea, allowing for the elimination of any refractive error and the obtainment of high levels of visual acuity, even potentially higher levels than those before the operation. The corneas are free of all abnormalities.
The automated microkeratome is an important advancement in the technology of refractive surgery in that laser treatment must be carried out inside the cornea, particularly in the corneal stroma.
Inside the microkeratome is the knife that makes the non-refractive incision. This knife is changed for every patient to guarantee the best quality incision.
Also part of the automated microkeratome is a suction ring, responsible for increasing the intraocular pressure and facilitating the making of the incision.
