The latest laser technology enables us to make a thinner corneal flap, which is quicker and also easier for patients to recover.

Commonly, this flap was created with a microkeratome, which had specific dangers. Today we make use of a femtosecond IntraLase laser to create the flap, which is a lot more precise and also much safer.
The Femtosecond Laser
Historically, traditional LASIK surgical procedure made use of a mechanical cutting tool called a microkeratome to develop a hinged flap on the cornea. The surgeon then folded up back the flap to access the eye's underlying tissue. The surgeon after that utilized an excimer laser to reshape the corneal tissue, dealing with refractive errors like nearsightedness and farsightedness.
The femtosecond laser used for LASIK procedures offers substantial advantages over traditional tools, consisting of increased safety and security, far better healing, and also precise results. The femtosecond laser's powerful pulses of light interfere with the corneal tissues in a specifically controlled fashion.
The femtosecond laser's wise energy control also enables specialists to track eye activity 200 times per second, which guarantees that every laser pulse is completely precise. This allows surgeons to perform excellent lamellar and also permeating keratoplasties along with clear corneal lacerations, cataract surgery, and a lot more. The result is a tailored treatment that provides people with exceptional visual outcomes. In fact, lots of New york city City laser eye cosmetic surgeons compare the personalized results to those attained with get in touch with lenses and also glasses.
The IntraLase Flap
The primary step of the LASIK treatment entails creating a flap on the corneal epithelial surface. Generally this was performed with a hand-held bladed instrument known as the microkeratome. Since the microkeratome makes physical contact with your eye, it can present a component of risk to the surgery.
The femtosecond laser is much more secure for this crucial initial step of the LASIK treatment because it does not make physical contact with your eye. Instead the femtosecond laser develops a pattern of tiny bubbles below the corneal surface area that after that attach to form the flap.
https://www.medicalnewstoday.com/articles/326346 enables the doctor to establish precise criteria for the flap density, deepness and also hinge location. This gives the doctor with a high degree of customization that eliminates complications connected with the flap and also makes sure an extra successful LASIK end result. It also permits even more people with slim corneas, that were rejected as LASIK candidates in the past, to receive the treatment and appreciate improved vision.
The SMILE Treatment
The FDA has actually just approved a new refractive surgery treatment that is a different to LASIK called tiny cut lenticule removal (SMILE). It is an outstanding laser therapy option for individuals with nearsightedness, or nearsightedness.
During the SMILE treatment, a Visumax femtosecond laser produces pulses that will certainly specify and establish an overview of a thin lens-shaped piece of corneal tissue, called a lenticule. The cosmetic surgeon after that produces a keyhole cut on the corneal surface area, as well as removes the lenticule to reshape the cornea and proper vision.
The reality that SMILE does not call for a flap might help to minimize completely dry eye signs and symptoms after the treatment, and also it also appears that the little lenticule cut creates less damage to the corneal nerves, causing far better biomechanical stability in the long run. These advantages, together with the reality that SMILE deals with a broader range of nearsightedness problems than keratomileusis does, make SMILE an attractive alternative for numerous people.
The Excimer Laser
The excimer laser makes use of ultraviolet radiation to transform the corneal shape, reducing refractive errors such as nearsightedness (nearsightedness), hyperopia (farsightedness) and astigmatism. It is the most crucial tool in Lasik surgical procedure as well as the trick to removing your dependency on glasses and also contact lenses.
Excimer lasers make use of a mix of 2 gases, usually argon fluoride or krypton fluoride to develop 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 triggering any type of damage to other close-by eye tissue.
Unlike previous excimer lasers, the WaveLight EX500 has integrated non-contact real-time pachymetry, which offers Dr. George split second responses on the development of your treatment, making sure that your corneal thickness is being accurately lowered as planned. This assists the physician understand that the femtosecond laser is developing the flap at the right fixed thickness, and verifies that the ablation quantity is being decreased as expected to treat your specific refractive error.
