The newest laser innovation enables us to make a thinner corneal flap, which is much faster and easier for individuals to heal. This also minimizes complications like glare and halos from the edges of the treatment zone.
Traditionally, this flap was produced with a microkeratome, which had specific threats. Today we make use of a femtosecond IntraLase laser to produce the flap, which is much more accurate and also much safer.
The Femtosecond Laser
Historically, conventional LASIK surgery used a mechanical cutting device called a microkeratome to develop a hinged flap on the cornea. The specialist then folded up back the flap to access the eye's underlying cells. The specialist after that made use of an excimer laser to reshape the corneal tissue, fixing refractive mistakes like nearsightedness as well as farsightedness.
The femtosecond laser made use of for LASIK treatments uses significant benefits over conventional tools, consisting of enhanced security, far better healing, and accurate outcomes. The femtosecond laser's effective pulses of light interrupt the corneal cells in a precisely controlled fashion.
The femtosecond laser's wise energy control also enables surgeons to track eye movement 200 times per second, which makes sure that every laser pulse is completely accurate. This allows specialists to perform best lamellar as well as permeating keratoplasties along with clear corneal cuts, cataract surgery, as well as more. The outcome is an individualized treatment that offers people with superb aesthetic results. In fact, many New York City laser eye cosmetic surgeons contrast the customized outcomes to those achieved with contact lenses as well as glasses.
The IntraLase Flap
The primary step of the LASIK treatment entails creating a flap on the corneal epithelial surface area. Typically this was done with a hand-held bladed tool known as the microkeratome. Since the microkeratome makes physical contact with your eye, it can introduce an aspect of danger to the surgery.
The femtosecond laser is much safer for this crucial initial step of the LASIK treatment since it does not make physical contact with your eye. Instead the femtosecond laser produces a pattern of microscopic bubbles below the corneal surface that after that attach to develop the flap.
This brand-new technique allows the cosmetic surgeon to establish specific specifications for the flap thickness, deepness and also joint location. This offers the specialist with a high degree of personalization that eliminates difficulties connected with the flap and makes sure a much more effective LASIK result. It additionally enables even more individuals with slim corneas, that were dismissed as LASIK prospects in the past, to get the procedure as well as enjoy boosted vision.
The SMILE Procedure
The FDA has just approved a brand-new refractive surgical treatment procedure that is a different to LASIK called small incision lenticule extraction (SMILE). It is an excellent laser treatment choice for patients with myopia, or nearsightedness.
Throughout the SMILE procedure, a Visumax femtosecond laser creates pulses that will certainly specify as well as establish an outline of a thin lens-shaped piece of corneal tissue, called a lenticule. The specialist after that creates a keyhole laceration on the corneal surface area, and gets rid of the lenticule to reshape the cornea as well as correct vision.
The truth that SMILE does not call for a flap may help to reduce completely dry eye signs after the procedure, as well as it likewise appears that the small lenticule cut creates less damages to the corneal nerves, bring about better biomechanical security in the long run. These advantages, in addition to the fact that SMILE deals with a broader series of nearsightedness problems than keratomileusis does, make SMILE an enticing choice for lots of clients.
The Excimer Laser
The excimer laser makes use of ultraviolet radiation to change the corneal form, minimizing refractive mistakes such as nearsightedness (nearsightedness), hyperopia (farsightedness) and astigmatism. It is one of the most essential piece of equipment in Lasik surgical treatment and the secret to removing your reliance on glasses and call lenses.
Excimer lasers use a combination of 2 gases, commonly argon fluoride or krypton fluoride to create a light beam of ultraviolet light which can be specifically focused. This enables the laser to disintegrate the carbon-to-carbon bonds in the corneal tissue without causing any damage to various other neighboring eye tissue.
Unlike previous excimer lasers, the WaveLight EX500 has actually integrated non-contact real-time pachymetry, which offers Dr. George split second comments on the progression of your treatment, ensuring that your corneal density is being properly decreased as prepared.
Check This Out helps the doctor understand that the femtosecond laser is creating the flap at the proper fixed thickness, and confirms that the ablation volume is being minimized as expected to treat your particular refractive error.
