To assess the change in ocular surface temperature between healthy phakic and pseudophakic patients.
We included patients with no history of ocular disease other than cataract. Patients were divided into three groups: clear lens, cataract, and pseudophakic. All patients had two ocular surface digital thermal scans. An average of five surface points was used as the mean ocular surface temperature. Results were analyzed with a one-way analysis of variance and a Tukey's least significance difference test. The patients were further divided into phakic and pseudophakic groups. Correlation coefficients between several variables were done in order to assess dependencies.
Fifty-six eyes (28 cataracts, 12 clear lenses, 16 pseudophakic) were enrolled. The mean ocular surface temperature in the cataract group was 34.14°C±1.51°C; clear lens: 34.43°C±2.27°C; and pseudophakic: 34.97°C±1.57°C. There were no statistical differences among the study groups (P=0.3). There was a nonsignificant negative correlation trend between age and surface temperature in the phakic group. The trend inverted in the pseudophakic group but without statistical significance.
Although cataract extraction and intraocular lens implantation seem to induce a mild increase in ocular surface temperature, the effect is not clear and not significant.
评估健康有晶状体眼和人工晶状体眼患者眼表温度的变化。
纳入除白内障外无眼部疾病史的患者。患者分为三组：透明晶状体组、白内障组和人工晶状体眼组。所有患者均进行两次眼表数字热扫描。平均五个表面点用作眼表平均温度。结果采用单因素方差分析和Tukey最小显著差异检验进行分析。患者进一步分为有晶状体眼组和人工晶状体眼组。计算几个变量之间的相关系数以评估相关性。
共纳入56只眼（28只白内障眼、12只透明晶状体眼、16只人工晶状体眼）。白内障组眼表平均温度为34.14°C±1.51°C；透明晶状体组：34.43°C±2.27°C；人工晶状体眼组：34.97°C±1.57°C。研究组之间无统计学差异（P = 0.3）。有晶状体眼组年龄与表面温度之间存在不显著的负相关趋势。人工晶状体眼组趋势相反，但无统计学意义。
虽然白内障摘除和人工晶状体植入似乎会使眼表温度轻度升高，但效果不明确且不显著。
