Here is a site about animations of Lasik surgery
LASIK is a form of laser-guided eye operation meant to repair difficulties with vision. The surgery is performed by ophthalmologists, who are medical doctors who specialize in eye disorders & diseases. LASIK is generally preferable to pRK (photorefractive keratectomy), as it is much less painful and requires less time to recover. Before having LASIK surgery, the patient's corneas are analyzed with a computerized scanner and a corneal map is devised. This stage of the process also discovers astigmatism as well as additional problems in the cornea's shape. The eye surgeon uses this information to compute the amount as well as location of corneal tissue to be removed during the surgery. The operation is carried out while the person is awake, still, the patient is generally given a modest sedating medication and anesthetic drops in the eyes. The surgeon operates the lasers, which produce all of the cutting. A flap is sliced in the cornea using a blade or a laser. Afterwards, an excimer laser is used to remodel the cornea. The laser vaporizes tissue without causing harm to the eye. Although usually uncommon, damaging complications could occur with LASIK or any eye surgeries. Some of the more frequently reported complications of LASIK can include: infection, dry or light sensitive eyes, over or under correction, fluctuations in vision, rings around lights, doubled vision, and issues with the flap created during the surgical procedure. Although LASIK technology is getting better quickly, research studies have not defined long-term or permanent damage. The surgical procedure is irreversible.
