手术过程中要轻柔操作,尽量减少对眼表面尤其是角膜上皮的机械损伤,熟练手术技巧,缩短手术时间,减少手术创面的暴露时间和暴露面积,注意手术当中的角膜上皮的保护。
术后在积极预防和控制炎症的基础上,应使用对眼表面上皮损伤少的滴眼液,并尽量减少滴眼液的使用频率。术后常规辅以人工泪液治疗,提高泪膜稳定性和缓解干眼症状,这些对亚临床干眼患者十分重要。
总之,白内障手术会给泪膜带来影响,临床上,对白内障术后泪膜功能的变化甚至术后干眼应给予足够的重视。随着生活质量的提高,患者对术后视功能改善的要求也越来越高,不仅要求可以看得见,而且要求看得舒服,这就要求我们重视术后泪膜功能的改善,以便最大可能地减少患者术后的主观不适感,促进泪膜功能的尽早恢复,提高患者的视觉质量。
