OBJECTIVE: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
