准分子激光屈光性角膜切削术和准分子激光原位角膜磨镶术可诱发或加重术后干眼症。这表现为症状的程度和频率增加，角膜发现，如浅表点状角膜病变，以及干眼症测试的异常结果，如Schirmer测试和泪膜破裂时间。原因主要涉及角膜感觉下降，导致泪腺反馈减少和泪液分泌减少。其他原因可能包括蒸发增加，炎症或药物毒性。干眼症很少会导致伤口愈合受损和角膜光学质量下降，但它是短暂的，持续几周到1年。应警告患者注意这种令人痛苦的并发症。在干眼症期间，人工泪液和泪点塞有助于预防或减轻患者的不适。(C)2001 Lippincott威廉姆斯& Wilkins，Inc.
Photorefractive keratectomy and laser in situ keratomileusis can induce or exacerbate dry eye after surgery. This manifests as an increase in degree and frequency of symptoms, corneal findings, such as superficial punctate keratopathy, and abnormal results of dry eye tests, such as the Schirmer test and tear break-up time. The cause mainly involves decreased corneal sensation, resulting in decreased feedback to the lacrimal gland and reduced tear production. Other causes may include increased evaporation, inflammation, or toxicity of medications. Dry eye may result infrequently in impaired wound healing and decreased optical quality of the cornea, but it is transient, lasting from a few weeks up to 1 year. Patients should be warned about this distressing complication. During a period of dry eye, artificial tears and punctal plugs are helpful in preventing or alleviating patient discomfort.
