Several studies have reported that cooling cornea has effects on alleviating pain post Photorefractive Keratectomy (PRK). However, our random prospective self-control study using 52 eyes of 26 myopic patients revealed that there was no significant statistical difference (P > 0.74) in the postoperative pains at both day-1 and day-3 between the experimental eye group (26 myopic eyes, treated with chilled lactated Ringer's saline of 4°C) and the control eye group (26 self control eyes, treated with lactated Ringer's saline of ˜20°C). The result suggests that applying low-temperature balanced saline solution onto corneal surfaces is not an effective analgesia for PRK surgery.
