The newest laser modern technology permits us to make a thinner corneal flap, which is faster as well as easier for individuals to recover. This likewise lowers problems like glare and halos from the sides of the treatment area.

Typically, click the up coming site was produced with a microkeratome, which had specific risks. Today we use a femtosecond IntraLase laser to produce the flap, which is a lot more accurate and safer.

The Femtosecond Laser

Historically, typical LASIK surgery used a mechanical reducing device called a microkeratome to create a hinged flap on the cornea. The specialist then folded up back the flap to access the eye's underlying cells. The surgeon then made use of an excimer laser to improve the corneal cells, dealing with refractive errors like nearsightedness and farsightedness.



The femtosecond laser used for LASIK procedures uses considerable advantages over standard tools, consisting of raised security, better recovery, as well as specific results. The femtosecond laser's powerful pulses of light disrupt the corneal cells in a specifically controlled manner.

The femtosecond laser's wise energy control additionally enables specialists to track eye activity 200 times per 2nd, which makes sure that every laser pulse is totally exact. This makes it possible for doctors to execute excellent lamellar as well as permeating keratoplasties along with clear corneal incisions, cataract surgery, and also extra. The outcome is a personalized therapy that supplies patients with exceptional aesthetic outcomes. As a matter of fact, many New York City laser eye specialists contrast the customized results to those attained with contact lenses and glasses.

The IntraLase Flap

The very first step of the LASIK treatment includes producing a flap on the corneal epithelial surface area. Commonly this was finished with a hand-held bladed tool called the microkeratome. Because the microkeratome makes physical contact with your eye, it can present a component of threat to the surgery.

The femtosecond laser is much safer for this vital first step of the LASIK treatment due to the fact that it does not make physical contact with your eye. Instead the femtosecond laser develops a pattern of microscopic bubbles below the corneal surface that then connect to create the flap.

This brand-new strategy enables the surgeon to establish specific criteria for the flap thickness, deepness and hinge location. This provides the surgeon with a high degree of personalization that eliminates problems associated with the flap and ensures a much more effective LASIK outcome. It likewise allows more people with slim corneas, that were rejected as LASIK candidates in the past, to get the procedure and also delight in improved vision.

The SMILE Treatment

The FDA has simply approved a new refractive surgery procedure that is a different to LASIK called tiny cut lenticule removal (SMILE). It is an impressive laser treatment choice for people with nearsightedness, or nearsightedness.

Throughout the SMILE treatment, a Visumax femtosecond laser creates pulses that will certainly define as well as develop a summary of a slim lens-shaped piece of corneal cells, called a lenticule. The surgeon after that creates a keyhole laceration on the corneal surface area, and removes the lenticule to improve the cornea as well as appropriate vision.

The fact that SMILE does not need a flap may aid to decrease completely dry eye signs after the procedure, and also it additionally shows up that the small lenticule laceration creates less damage to the corneal nerves, resulting in far better biomechanical security in the long run. These advantages, together with the reality that SMILE treats a more comprehensive range of nearsightedness issues than keratomileusis does, make SMILE an appealing option for many people.

The Excimer Laser

The excimer laser utilizes ultraviolet radiation to transform the corneal form, lowering refractive errors such as nearsightedness (nearsightedness), hyperopia (farsightedness) and also astigmatism. It is one of the most vital piece of equipment in Lasik surgery and also the key to eliminating your dependency on glasses and also contact lenses.

Excimer lasers use a mix of two gases, generally argon fluoride or krypton fluoride to create a beam of light of ultraviolet light which can be precisely focused. This enables the laser to disintegrate the carbon-to-carbon bonds in the corneal tissue without creating any kind of damage to various other nearby eye cells.

Unlike previous excimer lasers, the WaveLight EX500 has actually integrated non-contact real-time pachymetry, which provides Dr. George instant comments on the progression of your treatment, guaranteeing that your corneal density is being accurately lowered as planned. This assists the doctor recognize that the femtosecond laser is developing the flap at the appropriate predetermined thickness, and also confirms that the ablation volume is being minimized as expected to treat your specific refractive mistake.
