The application of laser in ophthalmology has led to a spectacular progress in the possibilities of treating of ocular disorders. Its maximum success is the Technique Lasik Multispot. This technique widely tested, allows the cornea to be remodelled through the exact and controlled application of multiple impacts of laser, approximately 100-130 microns below itself, correcting in an optimal and definitive way the myopia, hyperopia and astigmatism.
Stages
Operations are performed on an out-patient basis. This means that admission to hospital is not required and it takes only a few minutes. Anesthetic collyrium drops will be provided prior to the patient's entrance to the laser area.
1. Preparation: first, using an especially designed instrument, a thin flap of corneal tissue, of the thickness of a contact lens (100-130 microns thick, or 0,1 mm) is cut. This way we free the area where the laser is going to operate.
2. Laser: next, we apply the laser on the middle layer of the cornea for a few seconds. Lastly, the flap is dropped back into place with no need of stitches, for it heals over quickly due to its natural self-adherence. Laser application lasts between 1 and 3 minutes each eye. Both eyes are treated on the same day for the patient's convenience, the whole process taking between 6 and 10 minutes.
3. Post-operative care: after the operation, the patient rests at the clinic for about 30 minutes. At some point during this time the ophthalmologist will perfom the first eye check. Once this time is over, the patient can go home with eyes uncovered and 80% power of vision. It is recommended to rest for some hours without rubbing the eyes. In most cases vision will be excellent by the next day, making patients feel a spectacular change in their quality of life. The week after the operation, the patient will apply the collyrium prescribed by the ophthalmologist.
4. Check-ups: recovery is very fast. Generally, most patients resume their normal lives 24 hours after the operation. However, patients have to attend a series of regular check-ups (usually 3 or 4) so they can receive a customised post-operative follow-up before they can be given a certificate of discharge.
