LASIK ( laser in situ keratomileuses) is a procedure in which a laser is used to reshape your cornea — the clear, round dome at the front of your eye to improve the way your eye focuses light rays onto your retina. To see clearly, the cornea and the lens must bend or refract light rays so that they focus on the retina. The retina converts the light rays into impulses that are sent to the brain, where they are recognized as images. If the light rays don’t focus on the retina, the image you see is blurry. This is called a refractive error. Glasses, contact lenses, and refractive surgery try to reduce these errors by making light rays focus on the retina.
Refractive errors are vision problems caused by an eyeball or cornea that is not shaped perfectly. Refractive errors cause light from an object to be not focused on the retina of the eye. This causes a blurred image. Refractive errors usually occur in otherwise healthy eyes.
There are 4 types of refractive errors:
1. Nearsightedness (myopia).
2. Farsightedness (hyperopia).
3. Astigmatism( distorted vision)
4. Presbyopia( long sightedness due to the aging of the eye)
LASIK surgery can treat Myopia, Hyperopia, and Astigmatism.
Starting off with the preoperative LASIK evaluation is an extremely important and structured examination to determine if a patient is a good candidate for LASIK surgery. And our team ensures that every step of the procedure is done cautiously with proper attention and care. So Madhav Netralaya has brought two of the most advanced and accurate technology devices for the investigation and workup for LASIK that are
1. Oculyzer- We use the Wavelight Analyzer II diagnostic device which delivers correct data for eyes with lens opacity, haze along with an integrated eye tracker ensuring precise pupil. It can measure higher order aberrations up to the 6th order and has an integrated eye tracker for pupil centration.
2.Topolyzer- We use the Wavelight Topolyzer Vario diagnostic device which is an exceptional topography machine. The specialty of this machine is that it provides a complete map of the cornea which gives immediate visibility of the visual defects. The high reproducibility and accuracy of data are incredible. Also, it receives pupil centration in less than a second. These two high-end machineries have been approved by the US FDA. The presence of these highly accurate, precise machinery makes us one of the few eye hospitals in Central India to be equipped with these machines.
Many of the eye hospitals perform LASIK with the Blade procedure whereas we at Madhav Netralaya perform the bladeless surgery. Bladeless LASIK — also called blade-free LASIK, all-laser LASIK, or femto LASIK — Our LASIK Surgeon uses two types of lasers for the vision correction procedure.
First, an ultra-fast femtosecond laser that is LENSX Laser which is known to create precision and efficiency in refractive surgery is used to create a thin flap in the cornea (the clear front surface of the eye. The femtosecond laser eliminates the need for a bladed surgical tool (called a microkeratome) to create the corneal flap. No surgical blade of any kind is needed in all-laser LASIK. LENSX Laser is considered greater than other femtosecond lasers. It has an innovative, high definition of OCT technology.
Advantages of using LENSX Laser for the patients-
1. More predictable corneal flap thickness
2. Decreased risk of corneal abrasions during surgery
3. Decreased risk of induced astigmatism after LASIK
The LASIK procedure involves the following three steps.
1. Flap creation
2. Reshaping of Cornea with laser
3. Repositioning of the flap.
For the actual LASIK procedure, we use the EX500 Excimer Laser is used to reshape the underlying corneal tissue to correct your vision. The flap is then returned to its original position.
EX500 Excimer Laser is a state-of-the-art technology which provides a high level of precision and reliability to the patients and the surgeon. The advantages of using this machinery is the highly precise treatments, less dehydration of the cornea and fewer influences through a patient’s movement. It is a very safe machine as it ensures accurate placement of each laser pulse on the cornea.
We at Madhav Netralaya ensure that we provide our patients with the best and advanced technology for the best treatment. And the presence of high tech machinery and well-experienced team of doctors confirms our best service which makes us the best eye hospital in Nagpur.
