[Complications in excimer laser photorefractive keratectomy].
The complications of photorefractive keratectomy with excimer laser for myopia depend on preoperative myopia and inter-individual variability in wound healing. Loss of best corrected visual acuity is induced by Haze, irregular astigmatism and decentration. Haze is more frequent after treatment of high myopia. Decentration is a severe complication because its treatment is not well defined and is difficult. Corneal ulcerations infectious and non-infectious have been reported. Other complications are described: induced astigmatism, over and under corrections, central islands, halos, loss of corneal sensitivity, abnormal epithelial healing, recurrent epithelial breakdown, sterile corneal infiltrates, elevated intraocular pressure, subretinal hemorrhage.
