HOW DOES IT WORK?
In these types of interventions, the surgeon lifts a corneal flap (corneal flap) so that the excimer laser can remove corneal tissue and correct the refraction defect.
This cut in the corneal layer can be done with the microkeratome blade, which involves greater risks for the patient, or using the femtosecond laser, which is more accurate and safer.
The Institute uses this laser because it has great advantages:
Those patients who have thin, curved or flat corneas can undergo the operation.
In addition, it is very fast because it cuts in less than half a minute, emitting light pulse lasting less than a picosecond.
Also, the diameter and depth of the corneal flap is monitored, at all times, by software and by a real-time display on the screen.
Therefore, the Fernández-Vega Ophthalmological Institute uses the femtosecond laser as part of its equipment. Although it entails a higher investment cost, it offers the surgeon extra safety and precision that is superior to the manual technique during the cornea operation as well as offering greater tranquillity for the patient who is in good medical and technological hands.
