The most recent laser modern technology allows us to make a thinner corneal flap, which is much faster as well as easier for people to heal. This also decreases issues like glow and halos from the edges of the therapy zone.

Typically, this flap was produced with a microkeratome, which had certain dangers. Today we use a femtosecond IntraLase laser to create the flap, which is far more specific and more secure.

The Femtosecond Laser

Historically, conventional LASIK surgical procedure used a mechanical cutting device called a microkeratome to create a hinged flap on the cornea. The specialist then folded back the flap to access the eye's underlying tissue. The cosmetic surgeon after that utilized an excimer laser to improve the corneal tissue, remedying refractive errors like nearsightedness as well as farsightedness.



The femtosecond laser used for LASIK procedures offers substantial advantages over standard devices, including enhanced security, better recovery, and also accurate outcomes. 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 doctors to track eye motion 200 times per second, which makes sure that every laser pulse is totally exact. This makes it possible for specialists to do perfect lamellar as well as penetrating keratoplasties along with clear corneal incisions, cataract surgical treatment, and also extra. The outcome is a tailored treatment that supplies clients with superb aesthetic results. As check it out of fact, lots of New york city City laser eye cosmetic surgeons compare the individualized outcomes to those attained with get in touch with lenses and glasses.

The IntraLase Flap

The primary step of the LASIK procedure involves producing a flap on the corneal epithelial surface. Typically this was made with a hand-held bladed tool referred to as the microkeratome. Because the microkeratome makes physical contact with your eye, it can present an aspect of danger to the surgical procedure.

The femtosecond laser is much more secure for this essential primary step of the LASIK procedure because it does not make physical contact with your eye. Instead the femtosecond laser produces a pattern of microscopic bubbles underneath the corneal surface that then attach to form the flap.

This brand-new strategy allows the specialist to set accurate specifications for the flap thickness, deepness as well as joint area. This offers the specialist with a high level of modification that gets rid of difficulties related to the flap as well as guarantees a much more effective LASIK result. It additionally permits even more people with slim corneas, that were rejected as LASIK candidates in the past, to obtain the treatment and delight in improved vision.

The SMILE Treatment

The FDA has simply accepted a brand-new refractive surgery treatment that is an alternative to LASIK called small laceration lenticule extraction (SMILE). It is an outstanding laser therapy option for individuals with myopia, or nearsightedness.

Throughout the SMILE procedure, a Visumax femtosecond laser creates pulses that will certainly define as well as develop a summary of a slim lens-shaped item of corneal cells, called a lenticule. The surgeon after that develops a keyhole laceration on the corneal surface, as well as gets rid of the lenticule to improve the cornea as well as proper vision.

The truth that SMILE does not need a flap may help to minimize dry eye symptoms after the treatment, and it additionally shows up that the tiny lenticule laceration causes much less damage to the corneal nerves, leading to better biomechanical security in the future. These benefits, together with the truth that SMILE treats a broader variety of nearsightedness problems than keratomileusis does, make SMILE an attractive alternative for several individuals.

The Excimer Laser

The excimer laser utilizes ultraviolet radiation to change the corneal shape, lowering refractive mistakes such as myopia (nearsightedness), hyperopia (farsightedness) and also astigmatism. It is one of the most essential piece of equipment in Lasik surgical treatment and the trick to eliminating your reliance on glasses and call lenses.

Excimer lasers utilize a mix of two gases, usually argon fluoride or krypton fluoride to produce a light beam of ultraviolet light which can be exactly focused. This permits the laser to break apart the carbon-to-carbon bonds in the corneal cells 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 therapy, guaranteeing that your corneal thickness is being accurately reduced as intended. This aids the medical professional know that the femtosecond laser is creating the flap at the appropriate established density, and also confirms that the ablation volume is being minimized as expected to treat your certain refractive error.
