Complaints after photorefractive keratectomy (PRK) include both severe pain and a decrease in quality of vision due to corneal subepithelial haze. We suspect that one of the causes of these troubles is a temperature rise at the corneal surface during ablation. We cooled down the eye with cold balanced salt solution before and after photorefractive keratectomy. Postoperatively, this reduced severe pain, subepithelial corneal haze and any damage to the corneal endothelium.
准分子激光角膜切削术（PRK）后的并发症包括剧痛以及由于角膜上皮下混浊导致的视力下降。我们怀疑这些问题的原因之一是消融过程中角膜表面温度升高。我们在准分子激光角膜切削术前和术后用冷平衡盐溶液冷却眼睛。术后，这减轻了剧痛、角膜上皮下混浊以及对角膜内皮的任何损伤。
