Evaluate the pattern of intraocular pressure (IOP) variations through the pneumatic tonometer, between two specific surgical techniques, and the possible variables that may influence the behavior of this pressure.
Retrospective cross-sectional study carried out through the review of electronic medical records of a private ophthalmological reference hospital in the city of Goiânia, Goiás, Brazil, from 2012 to 2016, comprising of a sample of 550 eyes. The analyzed variables were, age, gender, IOP, axis, pachymetry, anterior chamber depth, and axial length.
In the end, the study consisted of 231 eyes, represented by 179 patients. Of these, 182 eyes were operated on by isolated cataract surgery, with a mean age of 72.0±9.5 years. The combined surgery represented a total of 49 eyes, 34 patients with a mean age of 71.9±8.14 years. There was statistical significance (<0.05) in correlating the pre- and postoperative IOP values in the 24-hour, 7-, 15-day, and 12-month postoperative periods.
A standard of variation of IOP was found through the pneumatic tonometer in both surgical techniques, but a more significant reduction was observed in combined surgery than in isolated cataract surgery, and further studies with a greater epidemiological impact are required for confirmation of this conclusion.
通过眼压计评估两种特定手术技术之间眼内压（IOP）的变化模式，以及可能影响该压力变化的变量。
通过回顾巴西戈亚斯州戈亚尼亚市一家私立眼科专科医院2012年至2016年的电子病历进行回顾性横断面研究，样本包括550只眼睛。分析的变量包括年龄、性别、眼压、眼轴、角膜厚度测量、前房深度和眼轴长度。
最终，该研究包括231只眼睛，由179名患者代表。其中，182只眼睛接受了单纯白内障手术，平均年龄为72.0±9.5岁。联合手术共49只眼睛，34名患者，平均年龄为71.9±8.14岁。在术后24小时、7天、15天和12个月期间，术前和术后眼压值的相关性具有统计学意义（<0.05）。
通过眼压计在两种手术技术中均发现了眼压变化的标准，但联合手术中观察到的眼压降低比单纯白内障手术更显著，需要进一步开展具有更大流行病学影响的研究来证实这一结论。
