Although there is an increased controversy on the safety and long term effect of laser eye surgery among those who went through the medical procedure, an in depth study on the matter is being conducted to understand the procedure and its effects better. According to those who are doubtful of the surgical procedure, the process may be incurring more harm than good among those who subject themselves to the treatment. However, based on the recent findings of Mayo Clinic in Minnesota, their studies reveal that there is no long term damage on the lining of the corneal cells which is associated to laser surgery.
The study was conducted before an actual laser eye surgery and nine years following the procedure. Before the surgery, pictures were taken on the endothelial cells of the cornea. Every year, the endothelial cells of the patients were taken pictures for 9 years to accurately monitor their development. For comparison purposes, a set of individuals who did not go through laser eye surgery were taken images of their endothelial cells as well.
According to the study, a 5.3% reduction of the density of the endothelial cells over 9 years was noticed among those who had laser eye surgery. One could say that this is quite high. However, if placed alongside with the 0.6% decline of endothelial cells per year among those who did not have laser eye surgery, the result would be similar to those who had laser eye surgery if the yearly decline would be added to 9 years.
The scientific experiment focused among those who went through PRK or photorefractive keratectomy and LASIK or Laser-assisted in situ keratomileusis. This provided hopes and reassurances among those who need donated tissues to treat corneal problems such as posterior lamellar keratoplasty. Based on the extensive research of the time focussing on corneal transplant, anyone who has gone through laser eye treatment are qualified to go through cornea transplant surgery. It is then recommended for patients to talk with their doctors to determine if they are fit to undergo the procedure or not.
