IntraLase vs Microkeratome
In your research on LASIK, the latest laser technologies, the risks and complications, you’ve probably seen debate on which is the better instrument to create the flap - the IntraLase laser or the microkeratome. You probably also noticed that the answer is not as simple as one or the other, as there are advantages and disadvantages to both.
The IntraLase laser is a femtosecond laser, meaning that it’s an infrared laser that uses extremely short pulses of light. A femtosecond is a quadrillionth of a second. Such fantastic brevity enables extraodinary precision. A femtosecond laser can create a flap in corneas which are too thin for a microkeratome, and does it by creating microscopic bubbles across the desired location for the flap, at the exact depth required. The flap is then easily lifted and an excimer laser is used to do the actual reshaping of the cornea.
Advantages of the Microkeratome:
More comfortable for the patient
Faster recovery time
Less pain or discomfort
Less suction needed
Total treatment time is shorter than with IntraLase
No need for long-term steroid use
