干眼对屈光性白内障手术的影响

干眼是一类由多种因素引起的以泪膜稳态失衡为特点的眼表疾病,同时伴有泪膜不稳定、泪液渗透压升高、眼表炎性损伤以及眼表神经感觉异常导致的眼表症状。近年来随着环境污染、视频终端普及和生活方式的改变,干眼已成为临床最常见的眼科疾病之一,严重影响患者的视觉健康和生活质量,且发病有逐年增高和年轻化的趋势。虽然随着白内障手术技术和人工晶状体设计的不断进步,屈光性白内障手术已经被越来越多的医生和患者接受并取得了满意的效果,然而在临床实践中仍有部分患者未达到期望值,干眼是造成这类患者满意度降低的重要且常见的原因之一。屈光性白内障手术患者在围手术期不同的干眼干预措施,直接影响人工晶状体测算的准确性和术后屈光状态的稳定性。述评干眼在白内障患者中的发病率、白内障患者干眼的危险因素、术前干眼对屈光性白内障手术的影响、围手术期干眼干预对屈光性白内障手术的影响、屈光性白内障患者术后干眼的治疗,提出了重视干眼在屈光性白内障手术中的影响并科学合理地干预,是提高屈光性白内障手术安全性、准确性和患者满意度的重要措施。

Effect of dry eye on refractive cataract surgery

Dry eye is an ocular surface disease characterized by tear film homeostasis imbalance due to various factors. Dry eye is often accompanied by tear film instability, elevated tear osmolality, ocular surface inflammatory damage, and ocular surface nerve sensory abnormalities. With the environmental pollution, the popularity of video terminals, and the change in lifestyle, dry eye has become one of the most common ophthalmic diseases in clinical practice significantly affecting the visual health and quality of life. The incidence of dry eye has increased annually, and more commonly affects the younger population. With the continuous development in cataract surgery technology and intraocular lenses, refractive cataract surgery has been accepted by more doctors and patients and has achieved satisfactory results. However, in clinical practice, there are still some disgruntled patients. Dry eye is an important and common reason for the reduction in satisfaction. Different interventions for dry eye in the perioperative period of patients undergoing refractive cataract surgery directly affect the accuracy of intraocular lens measurement and the stability of the postoperative refractive state. This paper reviews the incidence of dry eye in cataract patients, the risk factors for dry eye, the impact of dry eye on refractive cataract surgery, the impact of preoperative dry eye intervention on refractive cataract surgery, and therapy for postoperative patients with dry eye. This study highlights the importance of dry eye in refractive cataract surgery and the scientific and reasonable way of dealing with this condition. It is an efficient measure to improve the safety, accuracy, and patient satisfaction of refractive cataract surgery.
