A large number of surgeons who are not familiar with the corrective laser eye surgery reluctant to adopt it and, for several reasons: First, this treatment is much more technically difficult and not suitable for surgeons who do practice that occasionally, then this technique is much more expensive; finally, there is always the fear of damaging the cornea by making a "bad break". Results have shown that it is extremely rare for a serious complication to occur when LASIK surgery is performed by an experienced surgeon.
In 1997, a group of specialists engaged in a systematic review of their first 5 000 LASIK surgeries in order to assess the safety of this technique. This analysis was conducted in two parts: the operative phase at the time of surgery and postoperative phase in the months following surgery.
The operative phase:
In the case of eight patients, keratome created a piece is too thin or too short. Each time the piece was re-installed and a new surgery is performed six months later, has proved a success. None of these patients eyes has suffered a loss of visual potential.
The postoperative phase:
- In three cases, the day after the operation, surgeons had to replace the strip that the patient had moved, by rubbing the eye despite the protective shell;
- After the first day, surgeons haven't found on the strip of any patient any "fine line" that could affect the quality of vision;
- In any case there has been infection;
- In any case there has been development of scarring on the cornea (which often occurs during a photo-ablation of the surface);
- In any case there was, in the slide, debris requiring that one raises the slide again to clean;
- In any case there was epithelial cells forming in the strip and requiring that it raises the slide again to rid of these "infiltration epithelial.
- The number of eyes who lost two lines of vision on the map of visual acuity was extremely low (0.08%).
