Corrective Laser Eye Surgery – Is it Dangerous to Opt for Them?
LASIK is a type of refractive laser eye surgery performed by ophthalmologists for correcting myopia, hyperopia, and astigmatism. Can this type of surgery be dangerous?
A large number of surgeons who are not familiar with the 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.
Note: If you find some technical terms here and you have a difficulty to understand them you can check my website at the bottom for simplified information.
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%).
