The latest laser innovation enables us to make a thinner corneal flap, which is faster and also easier for patients to recover. This additionally decreases problems like glow and also halos from the edges of the therapy zone.
Traditionally, this flap was created with a microkeratome, which had certain risks. Today we utilize a femtosecond IntraLase laser to produce the flap, which is a lot more accurate and also more secure.
The Femtosecond Laser
Historically, traditional LASIK surgery utilized a mechanical reducing tool called a microkeratome to produce a hinged flap on the cornea. The surgeon then folded back the flap to access the eye's underlying tissue. The specialist after that utilized an excimer laser to reshape the corneal cells, remedying refractive mistakes like nearsightedness as well as farsightedness.
The femtosecond laser utilized for LASIK procedures uses significant benefits over traditional tools, consisting of enhanced safety, far better healing, and also specific results. The femtosecond laser's effective pulses of light interfere with the corneal cells in an exactly controlled fashion.
The femtosecond laser's clever energy control also permits specialists to track eye movement 200 times per 2nd, which makes sure that every laser pulse is totally accurate. This allows surgeons to perform excellent lamellar as well as penetrating keratoplasties along with clear corneal lacerations, cataract surgical procedure, and also extra. The result is a tailored treatment that offers people with exceptional visual outcomes. As a matter of fact, lots of New York City laser eye surgeons contrast the individualized results to those attained with get in touch with lenses and also glasses.
The IntraLase Flap
The very first step of the LASIK treatment involves producing a flap on the corneal epithelial surface. Generally this was performed with a hand-held bladed tool referred to as the microkeratome. Given that the microkeratome makes physical contact with your eye, it can present an element of threat to the surgical treatment.
The femtosecond laser is much safer for this critical first step of the LASIK procedure since it does not make physical contact with your eye. Rather the femtosecond laser produces a pattern of tiny bubbles below the corneal surface that then attach to create the flap.
This brand-new strategy permits the specialist to establish exact specifications for the flap thickness, deepness and hinge place. This offers the doctor with a high level of personalization that gets rid of issues connected with the flap and makes certain a more successful LASIK end result. It likewise permits even more individuals with slim corneas, that were dismissed as LASIK prospects in the past, to obtain the treatment and take pleasure in enhanced vision.
The SMILE Procedure
The FDA has actually just accepted a brand-new refractive surgery treatment that is an alternative to LASIK called small laceration lenticule removal (SMILE).
read more is an excellent laser therapy choice for people with myopia, or nearsightedness.
Throughout the SMILE treatment, a Visumax femtosecond laser produces pulses that will certainly define as well as develop a summary of a thin lens-shaped piece of corneal cells, called a lenticule. The specialist after that creates a keyhole cut on the corneal surface, and also removes the lenticule to improve the cornea as well as proper vision.
visit the following website that SMILE does not need a flap may help to reduce completely dry eye signs and symptoms after the procedure, and it also appears that the tiny lenticule cut causes less damage to the corneal nerves, resulting in better biomechanical stability in the long run. These benefits, together with the reality that SMILE treats a more comprehensive series of nearsightedness issues than keratomileusis does, make SMILE an enticing choice for numerous people.
The Excimer Laser
The excimer laser makes use of ultraviolet radiation to change the corneal shape, lowering refractive mistakes such as myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. It is the most important piece of equipment in Lasik surgical procedure as well as the trick to eliminating your dependency on glasses as well as call lenses.
Excimer lasers make use of a mix of 2 gases, normally argon fluoride or krypton fluoride to produce a beam of light of ultraviolet light which can be precisely concentrated. This permits the laser to break apart the carbon-to-carbon bonds in the corneal cells without triggering any type of damage to other nearby eye tissue.
Unlike previous excimer lasers, the WaveLight EX500 has actually integrated non-contact real-time pachymetry, which offers Dr. George split second feedback on the progression of your treatment, ensuring that your corneal thickness is being properly minimized as prepared. This aids the physician know that the femtosecond laser is producing the flap at the proper predetermined thickness, and validates that the ablation quantity is being lowered as expected to treat your particular refractive error.
