To evaluate the intraocular pressure variation before and after phacoemulsification through pneumatic tonometry in addition to correlating it with the age, gender, and preoperative intraocular pressure of the patients evaluated.
This is a cross-sectional observational study. Inclusion criteria were older than 18 years, deep anterior chamber visualized by the slit lamp and estimation of open angle using the Van Herick technique, intraocular pressure less than 21 mmHg, without surgical complications, and without any ocular disease. The intraocular pressure was measured by the pneumatic tonometer. The intraocular pressure assessment was performed at the last consultation before phacoemulsification surgery and 30 days after.
A sample of 182 eyes was used. The mean age was 68.41 ± 10.84 years. Of the patient, 65% were females and 35% were males. The mean intraocular pressure in the preoperative period was 16.0 mmHg (±3.3 mmHg) and the mean intraocular pressure in the postoperative period was 13.44 mmHg (±3.31 mmHg). There was no correlation between intraocular pressure variations in both eyes (age-matched open angle) and age. There was a statistically significant correlation between the preoperative intraocular pressure value and the intraocular pressure changes in the postoperative period. In the comparison of the intraocular pressure variation between the genders, the female gender presented a statistically significant negative variation.
We conclude that the cataract surgery is related to the reduction of intraocular pressure in the postoperative period and this reduction is more influenced by its preoperative value. Other studies of high epidemiological impact are needed, which may corroborate that the cataract surgery could directly influence intraocular pressure variation.
通过气眼压计评估白内障超声乳化术前、后的眼压变化，并将其与所评估患者的年龄、性别及术前眼压进行关联分析。
这是一项横断面观察性研究。纳入标准为年龄大于18岁，裂隙灯检查可见前房深，采用范·赫里克技术估计房角开放，眼压低于21 mmHg，无手术并发症且无任何眼部疾病。使用气眼压计测量眼压。在白内障超声乳化手术前的最后一次会诊时及术后30天进行眼压评估。
共使用了182只眼的样本。平均年龄为68.41±10.84岁。患者中65%为女性，35%为男性。术前平均眼压为16.0 mmHg（±3.3 mmHg），术后平均眼压为13.44 mmHg（±3.31 mmHg）。双眼（年龄匹配的开角）眼压变化与年龄之间无相关性。术前眼压值与术后眼压变化之间存在统计学显著相关性。在比较不同性别间的眼压变化时，女性呈现出统计学显著的负向变化。
我们得出结论，白内障手术与术后眼压降低有关，且这种降低受术前眼压值的影响更大。需要开展其他具有高流行病学影响力的研究，以证实白内障手术可能直接影响眼压变化。
