This approach reduces complications, enhances safety and boosts accuracy. To understand the benefits of this all-laser technology, one must always know that LASIK is a two-step process. First, a small flap is created the outer covering of the cornea. Next, an excimer laser is used to reshape the cornea together with correct vision inaccuracies. That laser, called the IntraLase, emits a cool laser light that passes harmlessly through the surface of the eye to a predetermined point in the cornea. The laser yields a layer of very small bubbles, which gently lift and separate the tissue to create a corneal flap. Once the flap is manufactured and the cornea reshaped, the surgeon will move the flap back into place back into place, where it resets in the cornea without necessity for stitches.
The IntraLase process produces a uniform flap each time, drastically allowing a wider selection of candidates to qualify with regard to LASIK surgery.
Within conventional LASIK surgery, the surgeon utilizes a handheld instrument, known for a microkeratome, to manually cut a flap inside cornea. Using this procedure helps the surgery to advance more quickly than the IntraLase approach, but only by a few moments.
There are cases in which a candidate has had past refractive surgery and skilled a blade flap end result. Often in those cases, using the IntraLase approach to LASIK surgery could end up inadvisable, as the tiny bubbles that is generated by the laser can travel with the previous incision and get relating to the cornea and the focusing lens of the laser.
Take into account that both IntraLase and microkeratome LASIK treatments are surgery; thus, both have risks and potential complications associated with them, although rare in both cases. Some these complications are transient gentle sensitivity, swelling and holes inside corneal flap.
So which method is way better? The truth of the matter is that LASIK is one of the safest procedures in each of medicine, regardless of the method (IntraLase or microkeratome) made use of.
I have opted to use a Boston ophthalmologist who functions the IntraLase (bladeless) approach to LASIK surgery. I am confident that it the right decision for me personally. As always, remember to research your options and ask questions. Better you know, the more confident you will feel about your vision correction decision. . PresbyLASIK (also known as multifocal LASIK) is a laser eye surgery procedure to help patients achieve clear vision in any respect distances. The "presby" inside name refers to "presbyopia, " the gradual lack of reading vision that affects people over the age of 45. The "LASIK" in the name refers to traditional LASIK, a laser surgery that's used to treat myopia, hyperopia and astigmatism. As the blending these two words suggests, presbyLASIK is a treatment for presbyopia along with the other vision problems customarily treated with LASIK.
Until recently, the only treatment for presbyopia was bifocal eye glasses. However, today several new treatments are offered, including refractive lens change with premium intraocular lenses, multifocal contact lenses and monovision LASIK. The latter is a laser eye treatment in which one eye is corrected for distance vision and also the other for reading imaginative and prescient vision.
PresbyLASIK is definitely the next-generation treatment and contains a potential for surpassing all of the currently available presbyopia remedies. It is available in Canada and other parts of the world but has not yet been approved by the Food and Drug Administration for use in the united states.
Read on to acquire more information about how PresbyLASIK works and how it deviates from monovision LASIK.
Sow how does It Work?
PresbyLASIK works by reshaping the eye's cornea. Unlike traditional LASIK, which gets better vision only at one distance, presbyLASIK improves vision at several distances. It's accomplished by creating several power zones in the cornea for near, intermediate, and distance vision. This is similar to the focusing powers within presbyopia eyeglasses. However, the difference is which PresbyLASIK "implants" these powers in the eye. The patient fails to require eyeglasses because the attention itself provides the same (or better) centering powers.
