The newest laser technology enables us to make a thinner corneal flap, which is faster and easier for people to heal. This likewise decreases difficulties like glare and also halos from the sides of the therapy area.

Typically, this flap was created with a microkeratome, which had specific threats. Today we make use of a femtosecond IntraLase laser to create the flap, which is far more precise as well as much safer.

The Femtosecond Laser

Historically, conventional LASIK surgical procedure made use of a mechanical reducing tool called a microkeratome to produce a hinged flap on the cornea. The cosmetic surgeon then folded up back the flap to access the eye's underlying cells. The surgeon after that used an excimer laser to reshape the corneal tissue, fixing refractive errors like nearsightedness and farsightedness.



The femtosecond laser made use of for LASIK procedures provides considerable benefits over standard tools, including increased safety, better recovery, as well as accurate results. The femtosecond laser's effective pulses of light interfere with the corneal cells in a precisely regulated fashion.

The femtosecond laser's wise power control also allows specialists to track eye activity 200 times per second, which makes certain that every laser pulse is completely precise. This makes it possible for surgeons to carry out ideal lamellar as well as permeating keratoplasties as well as clear corneal incisions, cataract surgery, and also a lot more. The outcome is a personalized therapy that provides people with exceptional aesthetic results. Actually, several New York City laser eye doctors contrast the personalized results to those attained with call lenses and glasses.

The IntraLase Flap

The very first step of the LASIK procedure involves creating a flap on the corneal epithelial surface area. Traditionally this was finished with a hand-held bladed tool referred to as the microkeratome. Since the microkeratome makes physical contact with your eye, it can introduce a component of danger to the surgical procedure.

The femtosecond laser is much safer for this vital primary step of the LASIK treatment since it does not make physical contact with your eye. Rather the femtosecond laser develops a pattern of microscopic bubbles below the corneal surface that then attach to develop the flap.

This brand-new technique enables the cosmetic surgeon to set precise criteria for the flap density, deepness as well as hinge place. This provides the surgeon with a high degree of modification that eliminates difficulties related to the flap and ensures a more successful LASIK outcome. It likewise enables even more individuals with slim corneas, that were rejected as LASIK prospects in the past, to receive the treatment as well as enjoy enhanced vision.

The SMILE Treatment

The FDA has simply accepted a new refractive surgery treatment that is an alternative to LASIK called little incision lenticule extraction (SMILE). https://www.investopedia.com/terms/v/vision-care-insurance.asp is an outstanding laser therapy option for patients with nearsightedness, or nearsightedness.

Throughout the SMILE procedure, a Visumax femtosecond laser generates pulses that will certainly define and develop a rundown of a slim lens-shaped piece of corneal cells, called a lenticule. https://www.medicalnewstoday.com/articles/does-medicare-cover-glasses produces a keyhole laceration on the corneal surface, and eliminates the lenticule to improve the cornea and also appropriate vision.

The reality that SMILE does not require a flap may aid to decrease dry eye symptoms after the treatment, and also it also shows up that the small lenticule cut creates less damage to the corneal nerves, bring about better biomechanical security over time. These advantages, together with the truth that SMILE treats a broader range of nearsightedness issues than keratomileusis does, make SMILE an appealing choice for lots of patients.

The Excimer Laser

The excimer laser uses ultraviolet radiation to change the corneal form, decreasing refractive errors such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. It is the most crucial tool in Lasik surgery and also the secret to removing your dependence on glasses and get in touch with lenses.

Excimer lasers use a combination of 2 gases, commonly argon fluoride or krypton fluoride to produce a beam of light of ultraviolet light which can be precisely concentrated. This allows the laser to break apart the carbon-to-carbon bonds in the corneal tissue without creating any damage to other neighboring eye cells.

Unlike previous excimer lasers, the WaveLight EX500 has actually integrated non-contact real-time pachymetry, which gives Dr. George immediate feedback on the progression of your treatment, making sure that your corneal density is being precisely reduced as planned. This helps the medical professional know that the femtosecond laser is creating the flap at the correct established density, as well as verifies that the ablation volume is being decreased as expected to treat your specific refractive mistake.
