The newest laser technology permits us to make a thinner corneal flap, which is faster and easier for individuals to recover.

Generally, this flap was developed with a microkeratome, which had certain dangers. Today we use a femtosecond IntraLase laser to create the flap, which is much more precise and safer.
The Femtosecond Laser
Historically, typical LASIK surgical treatment used a mechanical reducing device called a microkeratome to produce a hinged flap on the cornea. The surgeon then folded back the flap to access the eye's underlying tissue. The specialist after that utilized an excimer laser to improve the corneal cells, dealing with refractive mistakes like nearsightedness as well as farsightedness.
The femtosecond laser made use of for LASIK procedures provides considerable benefits over standard tools, including boosted safety, far better healing, and accurate outcomes. The femtosecond laser's effective pulses of light interfere with the corneal tissues in a precisely controlled way.
The femtosecond laser's smart power control additionally permits cosmetic surgeons to track eye motion 200 times per second, which makes certain that every laser pulse is completely exact. This makes it possible for surgeons to carry out best lamellar and permeating keratoplasties as well as clear corneal lacerations, cataract surgical procedure, and also more. The outcome is a personalized therapy that offers patients with outstanding visual outcomes. As a matter of fact, lots of New York City laser eye specialists contrast the customized outcomes to those attained with call lenses and also glasses.
The IntraLase Flap
The first step of the LASIK procedure entails developing a flap on the corneal epithelial surface area. Typically this was performed with a hand-held bladed instrument referred to as the microkeratome. Considering that the microkeratome makes physical contact with your eye, it can present an element of danger to the surgical procedure.
The femtosecond laser is much safer for this crucial initial step of the LASIK procedure due to the fact that it does not make physical contact with your eye. Rather the femtosecond laser creates a pattern of tiny bubbles underneath the corneal surface that after that connect to develop the flap.
This new strategy permits the cosmetic surgeon to set exact specifications for the flap thickness, deepness as well as joint location. This gives the cosmetic surgeon with a high degree of customization that removes issues related to the flap as well as makes sure a much more successful LASIK result.

The SMILE Treatment
The FDA has actually simply approved a brand-new refractive surgical treatment procedure that is an alternate to LASIK called small laceration lenticule extraction (SMILE). It is an impressive laser therapy choice for patients with myopia, or nearsightedness.
Throughout the SMILE treatment, a Visumax femtosecond laser generates pulses that will certainly specify as well as develop a summary of a thin lens-shaped item of corneal tissue, called a lenticule. The surgeon after that produces a keyhole laceration on the corneal surface area, and also removes the lenticule to reshape the cornea and correct vision.
The fact that SMILE does not call for a flap might help to reduce dry eye signs and symptoms after the procedure, as well as it likewise shows up that the tiny lenticule laceration causes much less damages to the corneal nerves, causing much better biomechanical stability over time. These advantages, in addition to the reality that SMILE treats a broader range of nearsightedness troubles than keratomileusis does, make SMILE an enticing choice for numerous people.
The Excimer Laser
The excimer laser utilizes ultraviolet radiation to change the corneal shape, lowering refractive mistakes such as nearsightedness (nearsightedness), hyperopia (farsightedness) as well as astigmatism. It is the most essential piece of equipment in Lasik surgical procedure and the key to eliminating your reliance on glasses and also get in touch with lenses.
Excimer lasers make use of a mix of two gases, usually argon fluoride or krypton fluoride to create a beam of light of ultraviolet light which can be specifically focused. This allows the laser to disintegrate the carbon-to-carbon bonds in the corneal cells without causing any type of damage to various other neighboring eye tissue.
Unlike previous excimer lasers, the WaveLight EX500 has actually integrated non-contact real-time pachymetry, which gives Dr. George instant comments on the progress of your treatment, making certain that your corneal density is being accurately decreased as intended. This aids the doctor know that the femtosecond laser is producing the flap at the proper predetermined density, and verifies that the ablation volume is being reduced as expected to treat your details refractive mistake.
