The latest laser technology enables us to make a thinner corneal flap, which is much faster and also easier for patients to recover. This also minimizes difficulties like glare and halos from the edges of the treatment area.
Typically,
look at more info was developed with a microkeratome, which had particular dangers. Today we make use of a femtosecond IntraLase laser to create the flap, which is far more exact and much safer.
The Femtosecond Laser
Historically, typical LASIK surgery made use of a mechanical reducing tool called a microkeratome to produce a hinged flap on the cornea. The surgeon after that folded back the flap to access the eye's underlying tissue. The specialist after that used an excimer laser to reshape the corneal tissue, fixing refractive errors like nearsightedness as well as farsightedness.
The femtosecond laser made use of for LASIK treatments supplies considerable advantages over standard devices, consisting of increased security, far better recovery, and exact results. The femtosecond laser's effective pulses of light interfere with the corneal tissues in an exactly controlled way.
The femtosecond laser's smart energy control also enables surgeons to track eye movement 200 times per 2nd, which makes sure that every laser pulse is totally exact. This allows cosmetic surgeons to perform best lamellar as well as passing through keratoplasties in addition to clear corneal lacerations, cataract surgical procedure, as well as more. The outcome is an individualized treatment that gives clients with exceptional aesthetic results. Actually, several New york city City laser eye specialists contrast the customized outcomes to those achieved with contact lenses and also glasses.
The IntraLase Flap
The initial step of the LASIK procedure entails creating a flap on the corneal epithelial surface area. Typically this was made with a hand-held bladed instrument known as the microkeratome. Given that the microkeratome makes physical contact with your eye, it can present an element of threat to the surgical treatment.
The femtosecond laser is much more secure for this vital very first step of the LASIK treatment because it does not make physical contact with your eye. Rather the femtosecond laser creates a pattern of microscopic bubbles underneath the corneal surface that after that connect to form the flap.
This new strategy allows the specialist to establish precise parameters for the flap thickness, deepness and joint location. This offers the surgeon with a high level of customization that removes difficulties associated with the flap as well as makes sure a much more successful LASIK result.

The SMILE Treatment
The FDA has simply approved a brand-new refractive surgery treatment that is an alternative to LASIK called small laceration lenticule extraction (SMILE). It is an excellent laser treatment alternative for individuals with myopia, or nearsightedness.
Throughout the SMILE treatment, a Visumax femtosecond laser generates pulses that will specify as well as develop an overview of a thin lens-shaped piece of corneal cells, called a lenticule. The specialist after that develops a keyhole incision on the corneal surface, and also gets rid of the lenticule to improve the cornea and also proper vision.
The fact that SMILE does not need a flap might aid to decrease dry eye symptoms after the procedure, as well as it also appears that the little lenticule incision triggers less damage to the corneal nerves, resulting in much better biomechanical stability in the long run. These advantages, in addition to the truth that SMILE treats a more comprehensive range of nearsightedness issues than keratomileusis does, make SMILE an attractive alternative for numerous patients.
The Excimer Laser
The excimer laser makes use of ultraviolet radiation to alter the corneal shape, reducing refractive mistakes such as myopia (nearsightedness), hyperopia (farsightedness) and also astigmatism. It is one of the most important tool in Lasik surgical treatment and the trick to eliminating your dependence on glasses and get in touch with lenses.
Excimer lasers utilize a combination of 2 gases, usually argon fluoride or krypton fluoride to create a light beam of ultraviolet light which can be specifically concentrated. This permits the laser to break apart the carbon-to-carbon bonds in the corneal tissue without triggering any damages to various other nearby eye cells.
Unlike previous excimer lasers, the WaveLight EX500 has actually incorporated non-contact real-time pachymetry, which provides Dr. George immediate responses on the development of your treatment, making certain that your corneal density is being properly decreased as intended. This assists the doctor understand that the femtosecond laser is producing the flap at the right predetermined density, and confirms that the ablation quantity is being reduced as anticipated to treat your particular refractive mistake.
