LASIK is a type of laser eye surgery for spectacle removal. It stands for Laser Assisted In-situ Keratomileusis which means change the shape of the cornea by means of laser to correct your refractive error.
It is done to treat following refractive errors:
In this the flap is created using a mechanical microkeratome (a blade device) which creates a thin 90 microns flap. This technique is fast and comfortable but might lead to flap related problems in a few cases.
In this, the flap is created using a laser device (femtosecond laser). This laser is a very advanced technology where ultrafast, low energy laser pulses are used to create microscopic separation leading to a superficial flap. This leads to a better flap morphology and stability. This surgery is more safe, more predictable, more precise, and accurate, painless, and has less risk of flap related problems.
In this procedure only one type of laser is needed that is excimer laser. This has two steps first we remove the front surface of your cornea called as epithelium and then we reshape your cornea using excimer laser. Now, this removal of epithelium can be done manually by a bunt instrument by using alcohol drops or using a motorized brush.
Now, with the latest technology available at Anil Eye Hospital that is the Schwind platform, this first step of the epithelium removal can be done easily with laser only and it becomes a touch less procedure. So, this helps in early healing within 3 days and reduces pain and discomfort with maximum safety.
It has two steps in the first step, a mechanical microkeratome (a blade device) or a laser device (femtosecond laser) is used to cut a flap in the cornea. The second technique is called as bladeless LASIK. A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middle section of the cornea. Then in the second step, pulses from a computer-controlled excimer laser vaporizes a portion of the stroma which corrects your glasses number and then the flap is replaced.

Pentacam is a specialized imaging device used in ophthalmology to create detailed maps of the cornea, the front surface of the eye. It helps eye doctors assess various aspects of the cornea, such as its shape, thickness, and curvature.
Corneal topography is a diagnostic tool that maps the surface of the cornea, which is the clear front part of the eye. It creates a detailed, three-dimensional image of the cornea’s shape and curvature.
Optical Coherence Tomography (OCT) is a non-invasive imaging technique that uses light waves to create detailed cross-sectional images of the tissues inside your body.
A pre-LASIK examination is a comprehensive eye exam performed prior to LASIK (Laser-Assisted In Situ Keratomileusis) surgery. This examination is essential for determining the patient’s eyes’ overall health and suitability for the procedure. Various tests, such as corneal topography, corneal thickness measurement (pachymetry), refraction test, dilated eye examination, and tear film quality evaluation, are typically performed during the examination. These tests enable the ophthalmologist to evaluate the cornea’s shape, thickness, and any refractive errors, such as myopia, hyperopia, or astigmatism. In addition, the doctor may inquire about the patient’s medical history and current medications, and conduct a comprehensive discussion about the LASIK procedure, its potential risks, benefits, and anticipated outcomes. Overall, the pre-LASIK examination in India ensures that the patient is a good candidate for LASIK surgery and provides individualised recommendations based on the patient’s specific requirements and eye health.

LASIK is a type of laser eye surgery to remove the spectacle number. It stands for Laser Assisted In-situ Keratomileusis. This means to change the shape of the cornea by means of laser to correct your refractive error.
It is done to correct common refractive errors like myopia, astigmatism and hypermetropia.
The most common refractive error causing vision problem is near-sightedness or myopia. This condition leads to blurry vision for far away objects, while near vision is normal.
Astigmatism is another condition where you will be prescribed cylindrical number correction in your glasses. This happens when your cornea or lens is curved more in one direction or axis as compared to the other. Hence, images that you see will be blurred both for far and near. Hypermetropia is also called as far-sightedness where your vision will be blurry for near more and you will often experience headache and eye strain even for far looking objects.
These refractive errors can be corrected by other measures also like eyeglasses or contact lenses. However, you become dependent on glasses for a clear vision and daily use and maintenance of contact lenses becomes difficult. LASIK eye surgery provides you a wonderful option of enjoying the freedom and reducing dependence on glasses or contact lenses.
