When glasses or contact lenses become a trouble in your life, Lasik surgery offers an alternative that can give you clear vision again. The innovative technology treats the most common types of refractive errors that you may know as nearsightedness, farsightedness and astigmatism. Lasik surgery offers a highly successful approach to permanently improving your vision without ever having to use glasses or contact lenses again.
Your ability to see depends on the way that your eyes bend (refract) light. A refractive error occurs when they do not bend it perfectly, preventing the eye from focusing light correctly. Nearsightedness, farsightedness and astigmatism are common refractive errors that glasses and contact lenses can correct temporarily and surgery improves permanently.
Rays of light can bend when they pass through water or a cornea such as the clear front surface of your eye. An abnormally shaped cornea bends the light imperfectly leading to the refractive error. Anatomical features affect the ability of your eyes to refract light and focus properly.
Myopia meansnearsightedness, that means the near objects are clear but the distant objects appear blurry. If you have myopic eyes, the long length of your eyeball from front to back or deviations in the shape of your eye structures make your vision inadequate. In some patients, heredity is a factor, and other influences on your eye structure may include your age, ethnicity, gender or even how you use your eyes. The occurrence of myopia among teenagers in India is about 13 percent, and scientists note that the use of 300 million smartphones may have an impact on the statistic.
Farsightedness or hyperopia makes distant objects easier for you to see than those that are close to you. Symptoms may not attract your attention when you are young, but they may eventually create blurry vision when you look at objects that are both near and far away. Some indications that you are farsighted include eyestrain, headaches, squinting and blurry vision when you look at something that is close to you. Hyperopia occurs when eyeballs are too short or when the lens or the cornea has an abnormal shape. It can affect children as well as adults, and it may occur as an inherited condition. The frequency of occurrence of hyperopia in India and around the world is less than that for myopia.
A common form or refractive error, astigmatism prevents the eye from focusing light in a particular axis on the retina. It occurs when light bends differently from normal as it goes through the eyeball because of the oval shape of the cornea. Children and adults may experience astigmatism, often without noticing it. Signs of the problem include squinting and eyestrain, blurry vision at any distance, headaches and difficulty in night driving. The occurrence of astigmatism is so common that you may have some form of it that has existed since birth. It tends to follow hereditary lines, and it may accompany myopia, hyperopia or both types of refractive errors.
Lasik surgery provides a path to clear vision. You can achieve freedom from glasses, contact lenses and endless prescriptions with a procedure that permanently improves your vision.Lasik is laser assisted reshaping of the cornea to correct refractive errors, and provide you freedom from spectacles and glasses. There are different kind of procedures, blade assisted and bladeless LASIK.
Blade Lasik Procedures
In Blade procedures, a special blade called microkeratome is used to make the corneal flap and then Excimer Laser is used to correct the spectacle power. Modern microkeratomes are able to create flap almost similar to the ones created by Femto Lasers.
There are 2 types of Blade Lasik Procedures
1. Standard LASIK
2. Customised LASIK
This Laser treatment pattern involves customized Lasik. The optical aberrations of the eye are picked up by an aberrometer and are reduced by the Laser along with spectacle power treatment. Aspheric treatment gives better contrast. Some centres use the normal version of the keratome which picks up a flap of 160 microns. A flap once picked up, is replaced back after laser correction of the underlying corneal tissue.
This is the C-lasik as described above, but without the Aspheric component. This is good enough to correct the refractive error but does not give the advantage of improved contrast. The element of halo's and glare is more in this version while the cost is the lowest.
In the Blade-Less technique, there are no blades working on the eye. The whole procedure is done by the use of one or combination of two lasers; Femto Laser and Excimer Laser. The precision of Femto Laser is to the levels of 5 microns. Which means that if a human hair is 60 microns, a Femto laser can cut 6 layers in that hair, which is impossible with a blade. Therefore, Bladeless technique gives greater precision, better quality of vision and more safety.
Bladeless Lasik uses Femtosecond Laser, which is used to create an ultra thin flap in cornea, second is Excimer Laser which is used to reshape the cornea to induce correction. The flap is then positioned back which sticks to its place immediately. No blades are used at any time in the whole procedure. Bladeless Lasik has been approved by US-FDA in 2001.
At Complete eye care we offer entire spectrum of refractive surgeries including BLADELESS LASIK with best lasiksurgerons in Gurgaon/gurugram.
LASIK is a very safe procedures. These procedures are also US -FDA approved, which means they have been given safety clearance for Human Eyes. However, like any other surgical procedure it can have some complications which are extremely rare if a proper screening check is done prior to the procedure. Some patients might experience mild dryness in eyes which usually relieved by lubricating drops and disappears over time. Some may also experience temporary halos during night time which also reduces with time. Immediately after Lasik one might experience mild heaviness and blurring of vision. These are due to the effects of numbing eye drops used during procedure. All these are very very rare and can be easily managed by your doctor. Nobody in our surgical experience has ever lost sight due to this procedure.
To be a suitable candidate for Laser Vision Correction Surgery, you should be:
Whats the LASIK procedure involves?
DAY 1 PRE OPERATIVE CHECK UP (LASIK SCREENING)
LASIK is not right for everyone. To access your suitability for Lasik, a detailed evaluation has to be done. This is known as 'LASIK Screening'. It involves a series of investigative procedures such as pachymetry, refraction, topography, dry eye testing, cornea scanning, retina screening and doctor consultation. These procedures take around 2 hours. if you are using contact lenses, it is best to remove them three days before the procedure.
DAY 2 LASIK PROCEDURE
This procedure is done under local numbing eye drops only. No injections are used. The LASIK treatment time usually takes around 20 seconds per eye, and the whole procedure takes around 10 minutes per eye. You may leave the hospital 15 minutes after the LASIK procedure.
DAY 3 FOLLOWUP
A follow-up is done next to evaluate results.
You can book an appointment, at complete eye care, with Gurgaons best LASIK Surgeon to know is LASIK is suitable for you or not.
What if I'm found unfit for LASIK?
98% people are usually found fit for Lasik. If, however you are not suitable for Lasik, your doctor may suggest you alternative procedures for vision correction such as ICL, Advanced Surface Ablation etc.
How long does LASIK take?
The laser treatment itself usually takes around one minute. The whole procedure takes about 10 minutes for one eye.
What does the postLASIK care include
When you plan to undergo a cataract surgery later in life, one should inform the doctor about any previous procedures so that the treatment plan can be modified accordingly.
Once the postoperative follow-up and medications are over one can resume all normal activities like:
After the procedure majority of the people can return to work after 2-3 days. Most of the routine work can be done after 7 days. Jobs that are more physically demanding and involve exposure to liquids or dust might require a more graduated return to full activities, but are best discussed with your surgeon.
