本研究旨在檢視LASIK and PRK後眼痛的頻率和風險因素。該研究作為一項前瞻性研究，在兩個不同的中心進行。
研究納入了109名接受屈光手術的患者，其中87％接受LASIK手術，PRK。參與者在手術後3個月和6個月接受眼表健康的臨床檢查。持續性眼痛被定義為手術後3個月和6個月的數字評分量表（Numeric Rating Scale, NRS）得分均為3分或更高。將有持續性疼痛的患者與在這兩個時間點上NRS得分低於3分的對照參與者進行比較。
Title: Ocular Pain after Refractive Surgery
Interim Analysis of Frequency and Risk Factors
The purpose of the study was to examine the frequency and risk factors for ocular pain after laser-assisted in situ keratomileusis (LASIK), and photorefractive keratectomy (PRK) . The study was conducted as a prospective study involving individuals undergoing refractive surgery at two different centers.
A total of 109 individuals undergoing refractive surgery, with 87% undergoing LASIK and 13% undergoing PRK, were included in the study. The participants underwent a clinical examination focused on ocular surface health at 3 and 6 months after surgery. Persistent ocular pain was defined as a Numeric Rating Scale (NRS) score of 3 or more at both 3 and 6 months after surgery. A group of patients with persistent pain was compared to control participants who had NRS scores of less than 3 at both time points.
The results showed that the frequency of ocular pain increased after surgery. Before surgery, 7% of patients reported ocular pain with an NRS score of 3 or more. However, at 3 months after surgery, the frequency of ocular pain increased to 23%, and at 6 months, it was 24%. Among the participants, 11% reported persistent ocular pain at both 3 and 6 months after surgery.
The study identified risk factors for persistent ocular pain after refractive surgery. Factors such as preoperative pain, acute postoperative pain (Day 1) , depression symptoms, and the use of oral antiallergy medication before surgery were associated with an increased risk of persistent pain.
Overall, the study found that a significant proportion of individuals experience persistent ocular pain after refractive surgery. The findings suggest that neuropathic mechanisms may contribute to this pain. The study highlights the importance of identifying risk factors and developing preventive and treatment strategies to address persistent ocular pain after refractive surgery.
It is worth noting that this is an interim analysis of an ongoing study, and the results should be interpreted with caution. Further research is needed to validate the findings and investigate potential mechanisms underlying persistent ocular pain after refractive surgery.
