Laser surgery for refraction defects.

Refraction defects are myopia, hypermetropia and astigmatism, which may be isolated or may be associated with one of the other condition.

These defects may be corrected with lenses in glasses, with contact lenses or with surgery.

Because of the tremendous dependency and inconvenience that can be caused by the first two options, surgery represents an important step forward in improving the quality of life for those affected.

Suitable for.
All myopic, hypermetropic and/or astigmatic people older than 21 who depend on optical correction devices (glasses or contact lenses) and whose defect has been checked and stabilised.

Surgical technique.
After applying anaesthetic drops, a slice 160 microns thick is cut from the cornea, which, once lifted, allows the Excimer laser to act at the correct depth depending on the scale of the defect to be corrected. Once finished, the slice of cornea is put back in its place, sticking itself back on without the need for stitches.

After the operation.
The patient goes home by him or herself minutes after the operation, with the eyes uncovered and already without glasses, although with somewhat blurred vision, which improves in the days following the operation.

Postoperative care.
The eyes must not be rubbed during the first 2 days. Anti-inflammatory, antibiotic drops must be put in for a few days after the operation.
