The most recent laser innovation allows us to make a thinner corneal flap, which is faster as well as easier for individuals to heal. This likewise minimizes complications like glow and also halos from the sides of the treatment area.

Typically, this flap was created with a microkeratome, which had particular threats. Today we utilize a femtosecond IntraLase laser to create the flap, which is much more specific and also much safer.

The Femtosecond Laser

Historically, conventional LASIK surgical procedure utilized a mechanical cutting device called a microkeratome to produce a hinged flap on the cornea. The doctor then folded up back the flap to access the eye's underlying cells. The doctor after that made use of an excimer laser to reshape the corneal tissue, dealing with refractive mistakes like nearsightedness and also farsightedness.



The femtosecond laser used for LASIK treatments uses considerable benefits over traditional tools, consisting of raised security, much better healing, and also precise outcomes. The femtosecond laser's powerful pulses of light interfere with the corneal tissues in an exactly controlled way.

The femtosecond laser's clever power control likewise allows cosmetic surgeons to track eye motion 200 times per second, which makes certain that every laser pulse is entirely precise. This enables doctors to perform best lamellar and permeating keratoplasties as well as clear corneal incisions, cataract surgical treatment, as well as more. The outcome is an individualized treatment that provides individuals with outstanding aesthetic end results. Actually, lots of New York City laser eye specialists compare the personalized results to those achieved with get in touch with lenses and also glasses.

The IntraLase Flap

The initial step of the LASIK treatment entails producing a flap on the corneal epithelial surface area. Traditionally this was performed with a hand-held bladed tool known as the microkeratome. Given that the microkeratome makes physical contact with your eye, it can introduce a component of danger to the surgical treatment.

The femtosecond laser is much safer for this critical very first step of the LASIK procedure due to the fact that it does not make physical contact with your eye. Instead the femtosecond laser produces a pattern of microscopic bubbles beneath the corneal surface that after that link to create the flap.

This brand-new strategy enables the doctor to establish accurate criteria for the flap density, depth and joint location. This gives the surgeon with a high degree of modification that gets rid of problems connected with the flap and makes sure a much more successful LASIK result. It likewise enables even more people with slim corneas, that were rejected as LASIK candidates in the past, to get the procedure and take pleasure in boosted vision.

The SMILE Procedure

The FDA has simply accepted a new refractive surgery procedure that is a different to LASIK called tiny cut lenticule removal (SMILE). It is an excellent laser therapy option for patients with nearsightedness, or nearsightedness.

Throughout the SMILE procedure, a Visumax femtosecond laser generates pulses that will certainly specify as well as establish a synopsis of a slim lens-shaped piece of corneal tissue, called a lenticule. The doctor after that develops a keyhole incision on the corneal surface, and also eliminates the lenticule to improve the cornea and proper vision.

The truth that SMILE does not call for a flap might help to decrease completely dry eye symptoms after the treatment, and it additionally shows up that the small lenticule laceration creates less damages to the corneal nerves, leading to better biomechanical stability over time. These benefits, in addition to the truth that SMILE treats a more comprehensive range of nearsightedness problems than keratomileusis does, make SMILE an appealing choice for many individuals.

The Excimer Laser

The excimer laser utilizes ultraviolet radiation to transform the corneal shape, reducing refractive mistakes such as myopia (nearsightedness), hyperopia (farsightedness) as well as astigmatism. It is one of the most crucial tool in Lasik surgical procedure and also the trick to removing your reliance on glasses and also get in touch with lenses.

Excimer lasers utilize a mix of 2 gases, usually argon fluoride or krypton fluoride to develop a beam of light of ultraviolet light which can be specifically concentrated. This allows the laser to disintegrate the carbon-to-carbon bonds in the corneal tissue without creating any kind of damages to various other nearby eye cells.

Unlike previous excimer lasers, the WaveLight EX500 has incorporated non-contact real-time pachymetry, which provides Dr. Read the Full Guide on the development of your treatment, guaranteeing that your corneal density is being precisely minimized as planned. This aids the medical professional recognize that the femtosecond laser is producing the flap at the right fixed density, and also validates that the ablation volume is being reduced as anticipated to treat your details refractive error.
