As per UN data, Myopia (nearsightedness) in young Indians will be a major
cause of concern by 2050 (Source). Wearing spectacles or contact lenses that clear
your vision is a must when you witness any eye vision problems.
However, maintenance of spectacles and contact lenses can be a hectic
job. So how do you get rid of this mundane yet difficult task? Well, people
in the age group 18 – 55 looking to pursue a spectacle-free (or contact-lens-free)
life can opt for a refractive eye surgery called LASIK.
The field of eye surgery has witnessed several significant advancements
in the past few years, and bladeless eye surgery is considered to be one
such evolution. Angst due to eye surgeries can be permanently parked aside
with Bladeless LASIK surgery -
the most advanced form of eye surgery.
In this blog, we deep dive into this medical advancement called Bladeless
What is Bladeless LASIK Surgery?
Bladeless LASIK (also called Femtosecond LASIK) is a blade-free LASIK
(or an all-laser LASIK) for vision correction.
Bladeless Lasik Procedure
In bladeless LASIK surgery, two types of lasers are used by the surgeon
to correct the vision. The entire procedure includes the following steps:
Creation of the flap
A thin flap is created in the cornea using the ultra-fast Femtosecond
laser. The wavelength of the Femtosecond laser is 1053 nm, and it moves
a billion times faster than a blink of the eye.
Due to its ultra-fast speed, the chances of thermal damage are very less
thus making the Femtosecond laser an ideal tool for eye surgery.
Lifting the flap
The flap is then lifted to access the cornea underneath for the application
of the laser.
Reshaping the cornea
The excimer laser of wavelength 193 nm is used to reshape the cornea.
A calculated amount of tissue is removed from the cornea based on the patient’s
Repositioning the Flap
After reshaping the cornea, the flap created in the first step is repositioned
back in a way that there are no bubbles or debris.
Did you know that the entire process of Bladeless LASIK is completed in
less than half an hour!
How Bladeless LASIK differs from Blade LASIK
Bladeless LASIK surgery differs from the Blade LASIK (or Microkeratome
surgery) in the first step (i.e. creation of flap), where a Femtosecond
laser is used instead of a blade.
In comparison to Blade LASIK, Femtosecond lasers used in Bladeless LASIK
have better capability to distinguish light and darkness in various conditions.
It also leads to significantly fewer vision errors like blurred vision,
dual vision, etc.
Bladeless LASIK surgery cost is around 10~15% more than Blade LASIK surgery
but offers higher precision.
Advantages of Bladeless LASIK Surgery
Bladeless LASIK surgery is a very safe option for people who are looking
for vision correction. With the bladeless LASIK surgery, the risk of post-surgery
complications with the cornea flap is significantly reduced.
Here are the major benefits of bladeless LASIK surgery:
The risk of flap complication is reduced
More accurate post-operative outcomes
Lesser incidents of post-operative dry eyes
Lesser pressure to the eye during the surgical procedure
Does that mean that Bladeless LASIK is free from side effects? Most of
the time, bladeless LASIK has proven to be a very safe option. Complications,
though rare, can occur.
Side effects of Bladeless LASIK
Some of the complications that might arise post bladeless LASIK surgery
Halo and glare are some of the possible bladeless LASIK side effects.
These side effects mostly peak between 3 – 12 months after the surgery
and gradually reduce over time.
To summarize, bladeless LASIK is a vision correction surgery that is highly
safe and accurate compared to Microkeratome surgery (or Blade LASIK). It
is advisable to opt for eye hospitals that offer the best LASIK surgery
Centre for Sight is one of the best eye hospitals in India,
with state-of-the-art facilities and doctors specialized in performing
LASIK eye surgery. At CFS, Femtosecond laser is
the preferred procedure, making the eye hospital a preferred choice for
vision correction through bladeless LASIK surgery.
