Microkeratome
What is it?
A microkeratome is a kind of high-precision, computer-controlled surgical instrument that is used to create the corneal flap in LASIK Laser Eye Surgery.
How Does it Work?
During your procedure, you will lay on the treatment bed facing up to allow clear access to your eyes. Anaesthetic drops will be administered to numb the surface of your eyes and your eyelids will be held open with lid holders.
The microkeratome creates suction between it and the cornea, ensuring that your eye is held steady. When preparation is complete, the microkeratome will then create a circular corneal flap with a hinge, allowing access to the corneal tissue underneath. In many clinics, the corneal flap is now created using a femtosecond laser.
Your surgeon is then able to hold the flap open while your cornea is reshaped. After the procedure, this flap is placed back over the exposed area of the eye where it can heal within a matter of hours.
What are the Benefits?
The main benefit of creating a corneal flap in LASIK is the significantly reduced healing time, compared with surface procedures like PRK/LASEK. Patients who have LASIK treatment are usually ready to return to work the very next day.
What Will I Feel?
Due to the nature of this part of the procedure, you may feel a little pressure in your eye. While this may feel a little strange, the use of anaesthetic eye drops will ensure you won’t feel any pain. During this time, your vision may go dim or dark for a few seconds.
