The history of eyeglasses has its roots in the Middle Ages and within the confines of Venice where, almost by chance, the "glass wall", artisans engaged in the processing of rock crystal, invented the so-called "glass to read." Over the centuries, the glasses have added precision lenses and design to your look, and have been accompanied by increasingly more comfortable contact lenses. Even the technology and fashion but have managed to lose their definition of "accessories", this term the perception of "foreign objects" on the part of many people with vision problems like myopia, hyperopia and astigmatism. Although essential, glasses and contact lenses because they are often experienced as "other" as necessary in order to see clearly but "cumbersome". It is no coincidence that more and more people decide to turn to the only available solution to finally say goodbye to glasses and lenses, the refractive surgery .
A study made history
Although not so "Old" like glasses, studies on refractive surgery today can boast 100 years of life (in Italy came in 1990), during which scholars have succeeded to find the best technique of definitive correction of refractive defects eye. Over the decades we have moved from the extraction of the lens for the correction of myopia incisional techniques (cheratomia radial), the techniques of keratomileusis to the more modern use of the excimer laser and femtosecond solid state lasers, as well as to new intraocular lenses, also called "phakic IOL". The refractive defects of vision are due to a lack of focus images on the retina. These defects are corrected by the laser, which acts by changing the shape of the corneal surface and thus creating a sort of "slow organic" remedy.
Very often, rely on refractive surgery, the young people who do not live peacefully on their relationship with eyeglasses and contact lenses. In addition there are also those who have strong visual defects or defects in one eye and one very unbalanced, suffering from intolerance to contact lenses, or carry out work activities where the use of lenses is a problem.
A laser beam to the eye for every need
Nowadays, technology has made available different techniques of surgeons to perform refractive surgery, all share one element: the laser. There are in fact different techniques, each with its own characteristics: the technique " PRK" in which the excimer laser is used, the " LASEK, very similar to the first and the treatment" LASIK "the technology Innovative uses the Intralase femtosecond laser as it has completely replaced the use of micricheratomo blade used in Lasik.
Today the intervention of visual defects such as nearsightedness, farsightedness and astigmatism can be corrected safely and accurately by using two lasers: the femtosecond laser, Intralase, for the separation of a thin layer of the cornea and the excimer laser for photoablation of corneal tissue for refractive correction of the defect.
This method is called The FEMTO-LASIK or LASIK is so precise and safe even NASA, the American Space Agency, has accepted as a safe intervention that can undergo the pilots and astronauts.
Since 2007, Dr Claudio Lucchini, Milan ophthalmologist expert in refractive surgery, has introduced the I-LASIK as a routine operation to correct nearsightedness, farsightedness and astigmatism, but explains that the view is essential preoperative to assess if the patient can or may not be operated with this technique.
During the visit, the surgeon can collect a series of data as the measurement of visual defect, corneal topography, or the curvature of the cornea's surface, measure the thickness of the cornea and the pupil diameter. The operation is relatively simple, and takes place under local anesthesia without hospitalization and with the application of anesthetic eye drops. In most cases the intervention has definitive effects, time to get perfect vision to 10/10 are very short, three days with the I-LASIK and in the absence of pain, about ten days and with a certain discomfort with PRK and LASEK.
