The latest laser technology allows us to make a thinner corneal flap, which is much faster and easier for clients to heal. This additionally minimizes issues like glare and halos from the edges of the treatment zone.
Traditionally, this flap was produced with a microkeratome, which had specific threats. Today we utilize a femtosecond IntraLase laser to develop the flap, which is a lot more exact and safer.
The Femtosecond Laser
Historically, typical LASIK surgical procedure utilized a mechanical reducing device called a microkeratome to develop a hinged flap on the cornea. The doctor after that folded up back the flap to access the eye's underlying cells. The specialist then made use of an excimer laser to improve the corneal cells, correcting refractive mistakes like nearsightedness and farsightedness.
The femtosecond laser used for LASIK procedures offers significant advantages over conventional devices, consisting of raised safety and security, much better recovery, as well as specific outcomes. The femtosecond laser's effective pulses of light interfere with the corneal tissues in a specifically controlled manner.
The femtosecond laser's smart power control likewise allows doctors to track eye activity 200 times per 2nd, which ensures that every laser pulse is totally exact. This allows doctors to carry out best lamellar and also permeating keratoplasties in addition to clear corneal lacerations, cataract surgery, and extra. Best LASIK is an individualized therapy that offers patients with outstanding aesthetic end results. Actually, several New York City laser eye doctors contrast the personalized outcomes to those achieved with get in touch with lenses as well as glasses.
The IntraLase Flap
The initial step of the LASIK treatment includes developing a flap on the corneal epithelial surface. Commonly this was done with a hand-held bladed tool known as the microkeratome. Since the microkeratome makes physical contact with your eye, it can introduce an element of threat to the surgical treatment.
The femtosecond laser is much safer for this critical initial step of the LASIK procedure due to the fact that it does not make physical contact with your eye. Rather the femtosecond laser produces a pattern of microscopic bubbles beneath the corneal surface area that after that attach to create the flap.
This new method enables the surgeon to establish accurate specifications for the flap thickness, deepness and also hinge location. This supplies the doctor with a high level of personalization that eliminates complications related to the flap and also makes sure a much more successful LASIK result. It likewise enables more people with thin corneas, that were rejected as LASIK candidates in the past, to get the treatment and take pleasure in enhanced vision.
The SMILE Procedure
The FDA has actually simply accepted a brand-new refractive surgery treatment that is an alternative to LASIK called little incision lenticule removal (SMILE). It is an outstanding laser therapy option for people with myopia, or nearsightedness.
During the SMILE treatment, a Visumax femtosecond laser produces pulses that will certainly define and develop a summary of a thin lens-shaped item of corneal tissue, called a lenticule. The surgeon after that develops a keyhole incision on the corneal surface area, and removes the lenticule to improve the cornea as well as proper vision.
The reality that SMILE does not call for a flap might assist to lessen completely dry eye signs after the treatment, as well as it also shows up that the little lenticule incision creates much less damage to the corneal nerves, leading to much better biomechanical security in the long run. These advantages, in addition to the fact that SMILE deals with a more comprehensive series of nearsightedness issues than keratomileusis does, make SMILE an enticing alternative for numerous clients.
The Excimer Laser
The excimer laser makes use of ultraviolet radiation to alter 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 dependence on glasses and contact lenses.
Excimer lasers use a combination of 2 gases, commonly argon fluoride or krypton fluoride to produce a beam of ultraviolet light which can be exactly focused. This enables the laser to break apart the carbon-to-carbon bonds in the corneal cells without causing any kind of damage to other close-by eye cells.
Unlike previous excimer lasers, the WaveLight EX500 has integrated non-contact real-time pachymetry, which offers Dr. George immediate feedback on the progression of your treatment, making certain that your corneal density is being precisely decreased as planned. This helps the doctor know that the femtosecond laser is creating the flap at the appropriate predetermined thickness, and also confirms that the ablation volume is being lowered as expected to treat your certain refractive mistake.
