目的：评价ＰＲＫ术后角膜接触镜在角膜上皮愈合中的作用。方法：收集本院１９９８年８月～１２月ＰＲＫ术后病例，以术后配戴角膜接触镜１５４例（３０５只眼）为研究组，以术后涂抗生素眼膏、敷料包盖１８１例（３４１只眼）为对照组，比较两组术后上皮愈合的情况。结果：研究组，术后三天角膜上皮痊愈２９９只眼（９８．０３％），角膜出现丝状物１只眼（０．３３％），角膜出现膜状沉积物１１只眼（３．６３％）；对照组，术后三天角膜上皮痊愈１９６只眼（５７．４８％），角膜出现丝状物４５只眼（１３．２％），角膜出现膜状沉积物３３只眼（９．６８％）。两组结果有显著性差异。结论：ＰＲＫ术后，配戴角膜接触镜，能促进角膜上皮愈合速度，减轻角膜丝状物和角膜膜状物形成，从而减轻病人术后痛苦。
Objective: To evaluate the role of corneal contact lens in corneal epithelial healing after PRK surgery. Methods: A total of 154 patients (305 eyes) with postoperative PRK were collected from August 1998 to December 1998 in our hospital. The postoperative antibiotic ointment and dressing were used to cover 181 cases 341 eyes) as control group, compared the two groups of epithelial healing situation. RESULTS: In the study group, 299 eyes (98.03%) were corneal epithelial healed three days after surgery, 1 eye (0.33%) of corneal filaments and 11 eyes (3.63 %). In the control group, corneal epithelium recovered 196 eyes (57.48%) three days after surgery, 45 eyes (13.2%) of corneal filaments and 33 eyes (13 eyes) of corneal membranous deposits. 68%). There was a significant difference between the two groups. Conclusion: PRK surgery, wearing contact lenses, can promote the rate of corneal epithelial healing, reduce corneal filaments and corneal membrane formation, thereby reducing the patient’s pain after surgery.
