Using an infrared radiation thermometer and a laser flare-cell meter, we evaluated intraocular inflammation in 40 patients who had cataract surgery by measuring central corneal temperature, number of cells, and amount of flare in the anterior chamber. Patients were divided into two groups based on duration of surgery: Group A, more than 40 minutes; Group B, less than 40 minutes. In Group A (n = 32), corneal temperature (degrees Celsius) increased by 1.10 +/- 0.57, 0.75 +/- 0.69, 0.41 +/- 0.56, and 0.24 +/- 0.45 on days 1, 2, 14, and 30, respectively. Group B (n = 8) had no significant rise in corneal temperature, but cell count (mean +/- 1 SD) increased to 39.3 +/- 13.6, 36.4 +/- 18.1, 15.5 +/- 16.5, and 4.4 +/- 3.1 on days 1, 2, 7, and 14, respectively. Flare increased to 88.9 +/- 88.9, 45.8 +/- 30.1, 38.3 +/- 25.4, and 18.5 +/- 9.4 on days 2, 7, 14, and 30, respectively. These observations show that the longer the cataract surgery, the greater the inflammation. Although inflammation was evaluated quantitatively by both infrared radiation thermometer and laser flare-cell meter, the latter appears to be more sensitive. Thermometry will only detect the results of very traumatic surgery, with a corresponding breakdown of the blood-aqueous barrier.
我们使用红外辐射温度计和激光闪光细胞仪，通过测量中央角膜温度、前房细胞数量和闪光量，对40例接受白内障手术的患者的眼内炎症进行了评估。根据手术时间将患者分为两组：A组，手术时间超过40分钟；B组，手术时间少于40分钟。在A组（n = 32）中，术后第1天、第2天、第14天和第30天角膜温度（摄氏度）分别升高1.10±0.57、0.75±0.69、0.41±0.56和0.24±0.45。B组（n = 8）角膜温度无显著升高，但细胞计数（平均值±1标准差）在术后第1天、第2天、第7天和第14天分别增至39.3±13.6、36.4±18.1、15.5±16.5和4.4±3.1。闪光量在术后第2天、第7天、第14天和第30天分别增至88.9±88.9、45.8±30.1、38.3±25.4和18.5±9.4。这些观察结果表明，白内障手术时间越长，炎症越严重。虽然红外辐射温度计和激光闪光细胞仪都对炎症进行了定量评估，但后者似乎更敏感。测温仅能检测到创伤性极大的手术结果，伴有相应的血-房水屏障破坏。
