Dry eye is described as a multifactorial disorder of the tear film that occurs due to excessive tear evaporation or tears insufficiency, and so leads to ocular discomfort sensation and ocular tissue damage with time.
To assess the incidence of dry eye disease after uncomplicated phacoemulsification surgery in patients with no pre-existed dry eye.
This hospital-based cross-sectional study was conducted to assess the incidence of dry eye at 100 eyes of 100 patients who underwent uncomplicated phacoemulsification surgery, with age more than 45 years old. It is measured by dry eye tests Schirmer 1 and tear break up time.
This study showed that 22% of the patients who underwent uncomplicated phacoemulsification surgery suffered from dry eye with significant results at 1st week post-operative that improved over time.
There was a statistically significant drop in the results of the Schirmer test 1 and TBUT post phacoemulsification surgery, but with no clinical significance as they still at the normal range. The tear film assessment results at the 1st week post-operative were out of the normal range with TBUT and were borderline with ST1 in 22% of the patients. These results improved over time to return to the normal values within 12 weeks postoperatively.
干眼症被描述为一种泪膜的多因素疾病，其发生是由于泪液过度蒸发或泪液不足，随着时间的推移会导致眼部不适感和眼组织损伤。
评估无干眼症病史的患者在进行单纯白内障超声乳化手术后干眼症的发生率。
本基于医院的横断面研究旨在评估100例年龄超过45岁且接受单纯白内障超声乳化手术患者的100只眼中干眼症的发生率。通过Schirmer 1试验和泪膜破裂时间来测量。
本研究表明，接受单纯白内障超声乳化手术的患者中有22%患有干眼症，术后第1周结果显著，随着时间推移有所改善。
白内障超声乳化手术后Schirmer试验1和泪膜破裂时间的结果有统计学意义的下降，但由于仍在正常范围内，故无临床意义。术后第1周泪膜评估结果中，22%的患者泪膜破裂时间超出正常范围，Schirmer试验1处于临界状态。这些结果随着时间推移有所改善，术后12周内恢复到正常数值。
