LASER eye surgery is a well-known safe surgical option for removal of glasses. This is commonly known as LASIK. It is in practice from last the 2 decades.
Common refractive errors that can be corrected by Lasik laser surgery are:
LASIK (Laser Assisted in-SItu Keratomileusis) procedure adjusts the cornea by using lasers to ablate the cornea which creates a uniform shape that refracts light as desired by the eye so that the light rays focus on the retina.
In LASIK, a partial thickness flap is created in black part of the eye (cornea). This flap is lifted and with the help of an excimer laser system, glass power is removed by reshaping the cornea. This flap is then placed back on the cornea and this flap naturally stick to cornea.
Lasik is primarily of 2 types depending upon the instrument used for cutting the cornea.
Micro Keratome or Blade Lasik
This is the older version of lasik procedure in which corneal flap is cut with the help of motorized blade. Then cornea is reshaped to remove glass number with the help of excimer laser. Because of its manual in nature it has some flap related complication in very few cases, which can affect the final outcome of the procedure. Microkeratome or blade Lasik is not very popular now days because of its associated complications.
Femtosecond Or Bladeless Lasik
This is the advance and safer method of doing Lasik in comparison to blade Lasik. Femtosecond lasik is more precise in cutting the corneal flap without causing any problem. Femtosecond lasik can be done in some cases of thin cornea where blade lasik is not possible.
Why Choose Femto-LASIK
FEMTO-LASIK is Safe
Totally bladeless procedure so more safe
As it is a bladeless procedure it is more accurate and precise
After cutting the flap, flap can be easily lifted without any problem
The micro trauma in the cornea tissues is much smaller than when using the microkeratome
Much rarer side effects and complications
The chance of developing an inflammation after femto lasik is almost nil
FEMTO-LASIK is Accurate
The entire working process of the femtosecond laser can be monitored on the screen which means every step is under the proper visibility and control of the surgeon
You can observe the laser beam’s work from the monitor
The vacuum is constant during the procedure so cutting is better
FEMTO-LASIK is Fast
Femto Lasik system is ultra fast, the laser impulse frequency is measured in Megahertz
The procedure only lasts for a few minutes
The recovery period is faster than that with other methods
The Femto Lasik allows for thinner, uniformly cut corneal flap that complications are practically non-existent.
With these thinner flaps of around 90 microns, more corneal tissue is left behind, meaning not only an increase in long-term corneal stability, but also the opportunity to correct higher refractive errors.
LASIK can be of different types depending upon the software used to correct the number:
Wavefront Guided lasik
Topo Guided lasik
All these are complex laser profiles used for correct refractive error during the LASIK procedure. Ask your doctor which one suits for your eyes. Each profile has different advantages and limitations.
Advantages of Lasik
Independence from glasses
Independence from contact lenses
Better cosmetic appearance
Disadvantages of Lasik
Cost involved in the procedure
Dryness in the initial postoperative period
Are You Fit for Lasik Laser Surgery?
There are some basic requirement if you are planning to go for Lasik laser procedure.
Age should be more than 18 years
Glasses power should be stable for at least 1 year
Pentacam HR test should be normal
No systemic problems such as diabetes or thyroid problems
What to Expect After Lasik?
LASIK is a very safe and quick procedure. Surgical time is around 15 minutes for both the eyes. Surgery is done under topical anesthesia or eye drop anaesthesia. No bandage is required after the surgery. On the day of surgery vision is blurred for a few hours and then starts clearing up. By next day patient’s vision is almost normal. Patient needs to use drops as advised by the treating doctor. Artificial tear drop has to be used for three months after the surgery for taking care of post Lasik dryness.
The cost of the Lasik varies significantly depending upon the procedure you opt for. Femto Lasik or bladeless lasik goes upto 1 lakh rupees for both the eyes. Cost of the surgery also depends upon doctors experience, advanced laser system etc. With the current advanced laser systems which have better predictability, Lasik is a safe and effective procedure for glass removal.
Despite it having a high cost, LASIK is a useful procedure as it makes one free from glasses and contact lenses. It is a very comfortable experience for a person undergoing the surgery. It makes the life very convenient as one doesn’t have to look for glasses first thing in the morning.
