However, when considering LASIK, patients are often faced with a choice between traditional LASIK using a microkeratome blade and bladeless LASIK using a femtosecond laser. In this article, we will delve into the differences between these two procedures, weighing the advantages and disadvantages of each.
By the end, you will have a better understanding of the blade versus bladeless LASIK debate, allowing you to make an informed decision about which method might be right for you.
Definition of blade and bladeless LASIK
Before we can fully appreciate the differences between blade and bladeless LASIK, it is important to understand what each procedure entails.
1.
Traditional LASIK with a microkeratome blade: The traditional LASIK procedure involves creating a hinged flap on the front surface of the cornea using a microkeratome blade. This blade, resembling a tiny razor, is guided by a surgeon to create a precise incision on the cornea.
Once the flap is created, the surgeon uses a laser to reshape the corneal tissue underneath, correcting any refractive errors. 2.
Bladeless LASIK using a femtosecond laser: Bladeless LASIK, also known as all-laser LASIK, takes a different approach to creating the corneal flap. Instead of using a blade, a femtosecond laser is employed to create a more precise and customizable incision.
This advanced laser technology emits pulses of light that create microscopic bubbles within the cornea, allowing the surgeon to gently lift the flap and proceed with the corrective laser treatment.
Advantages and disadvantages of each LASIK procedure
Now that we have a basic understanding of the two procedures, let us explore the advantages and disadvantages of each. Traditional LASIK with a microkeratome blade:
Advantages:
