LASIK previously was performed using a mechanical blade called a microkeratome to make the corneal cut. But with modern technology now the procedures are different. Bladeless LASIK, or femto-LASIK, is becoming common these days with advancing technology. Both of these treatments correct problems with refraction like myopia, hyperopia, and astigmatism, but differ in cutting the corneal flap. This blog contrasts both to give you an idea of which may be best for your eye care needs.
LASIK (Laser-In Situ Keratomileusis) is a type of eye surgery that reshapes the cornea to correct your vision. By reshaping the cornea, light is focused properly on the retina, providing improved vision. It is commonly used to correct nearsightedness, farsightedness, and astigmatism.
The process typically begins with the removal of a thin flap from the cornea. In the case of bladed LASIK, this is done using a microkeratome. Bladeless LASIK uses a femtosecond laser instead of the blade, and is more accurate. Once the flap has been lifted, an excimer laser remodels the cornea. The flap is closed and the eye naturally heals.
Bladed LASIK, which is the traditional method, uses a microkeratome device to create the corneal flap. It is cost-effective but possibly carries a minor risk for flap complications and healing issues. Bladeless LASIK or femto-LASIK employs a femtosecond laser to create the flap, providing greater accuracy and customisation.
Topography-Guided LASIK: Makes use of precise mapping of the corneal surface to guide treatment.
Wavefront-Guided LASIK: Takes it one step ahead, scanning the whole eye, and this means very personalised correction and is the most advanced type.
Bladeless LASIK can be recommended by the best cornea specialist Perinthalmanna as it has better outcomes and lower chances of complications. The majority of ophthalmologists nowadays practice bladeless LASIK because it is predictable and safe.
The main differences are all about precision, safety, and possible side effects:
Bladeless LASIK produces better contrast sensitivity, more uniform flap thickness, and lower chances of dry eye. Bladed LASIK is faster and less expensive but may be a bit more prone to risks. Bladeless LASIK is a highly recommended surgery at a renowned centre like the best eye care hospital Malappuram because of its prosperous treatments and patient satisfaction.
Whether to choose bladed or bladeless LASIK depends on various things like your eye condition, budget, and lifestyle needs. Though traditional LASIK remains a safe alternative, the bladeless method has become the benchmark in eye surgery due to its added accuracy and lower rates of complications.
