The newest laser technology enables us to make a thinner corneal flap, which is faster and easier for individuals to heal. This also lowers problems like glare as well as halos from the sides of the therapy area.
Generally, this flap was developed with a microkeratome, which had certain risks. Today we make use of a femtosecond IntraLase laser to develop the flap, which is much more accurate and more secure.
The Femtosecond Laser
Historically, standard LASIK surgical treatment made use of a mechanical reducing device called a microkeratome to create a hinged flap on the cornea. The doctor then folded back the flap to access the eye's underlying cells. The cosmetic surgeon then utilized an excimer laser to reshape the corneal tissue, dealing with refractive mistakes like nearsightedness and also farsightedness.
The femtosecond laser utilized for LASIK procedures offers significant advantages over traditional tools, consisting of raised security, far better healing, as well as specific results.

The femtosecond laser's smart power control also permits doctors to track eye motion 200 times per second, which ensures that every laser pulse is completely precise. This makes it possible for doctors to do best lamellar as well as passing through keratoplasties as well as clear corneal lacerations, cataract surgical procedure, and more. The result is a personalized therapy that supplies individuals with exceptional aesthetic results. Actually, many New york city City laser eye specialists contrast the individualized results to those attained with get in touch with lenses and glasses.
The IntraLase Flap
The initial step of the LASIK treatment entails creating a flap on the corneal epithelial surface area. Generally this was performed with a hand-held bladed tool known as the microkeratome. Because the microkeratome makes physical contact with your eye, it can present an aspect of danger to the surgical treatment.
The femtosecond laser is much safer for this important initial step of the LASIK treatment since it does not make physical contact with your eye. Rather the femtosecond laser produces a pattern of microscopic bubbles underneath the corneal surface that after that connect to develop the flap.
This new method enables the cosmetic surgeon to set precise specifications for the flap thickness, deepness and also joint place. This supplies the specialist with a high level of modification that gets rid of complications associated with the flap and also makes certain a more successful LASIK result. It also allows even more people with slim corneas, who were dismissed as LASIK candidates in the past, to receive the procedure and also delight in improved vision.
The SMILE Treatment
The FDA has actually simply accepted a brand-new refractive surgical treatment treatment that is an alternate to LASIK called small incision lenticule removal (SMILE). It is an impressive laser therapy choice for people with nearsightedness, or nearsightedness.
Throughout the SMILE procedure, a Visumax femtosecond laser creates pulses that will certainly define and also develop an outline of a thin lens-shaped item of corneal cells, called a lenticule. The doctor then produces a keyhole cut on the corneal surface, and eliminates the lenticule to reshape the cornea as well as appropriate vision.
The reality that SMILE does not need a flap might assist to reduce completely dry eye signs after the procedure, as well as it also shows up that the small lenticule incision causes much less damage to the corneal nerves, leading to much better biomechanical security in the long run. These advantages, in addition to the fact that SMILE deals with a wider range of nearsightedness issues than keratomileusis does, make SMILE an appealing option for many people.
The Excimer Laser
The excimer laser makes use of ultraviolet radiation to change the corneal form, minimizing refractive errors such as myopia (nearsightedness), hyperopia (farsightedness) and also astigmatism. It is the most important tool in Lasik surgical treatment and the key to eliminating your dependence on glasses and also contact lenses.
Excimer lasers use a mix of two gases, typically argon fluoride or krypton fluoride to develop a beam of light of ultraviolet light which can be specifically focused. This permits the laser to break apart the carbon-to-carbon bonds in the corneal cells without creating any type of damages to various other close-by eye cells.
Unlike previous excimer lasers, the WaveLight EX500 has integrated non-contact real-time pachymetry, which provides Dr. George immediate comments on the progress of your treatment, making sure that your corneal thickness is being precisely lowered as intended. This aids the doctor understand that the femtosecond laser is developing the flap at the appropriate established density, as well as confirms that the ablation quantity is being decreased as anticipated to treat your certain refractive mistake.
