A cataract is a disease in which the lens of the eye becomes clouded, causing a partial or complete loss of vision. Phacoemulsification (PHACO) is a modern surgical technique used in cataract surgery. Study findings: This study observed changes in intraocular pressure (IOP) after surgery in 31 dogs (48 eyes) with cataracts that visited a veterinary hospital. The procedure involved a lens extraction by PHACO and the implantation of an intraocular lens (IOL). Postoperative ocular hypertension (POH) was defined as a postoperative IOP of 25 mmHg or higher. To assess changes in IOP, IOP measurements were performed at 1, 2, 3, and 20 h, and at 1, 2, 3, 4, and 8 weeks after surgery. The IOP was found to be significantly higher at 1 ( < 0.05), 2 ( < 0.01), and 3 ( < 0.01) hours postoperatively compared with preoperatively. The IOP measurements were compared by dividing them into three groups according to the observation period. The IOP values were measured for three groups: before cataract surgery (Group A: 13.10 ± 8.29 mmHg), 1 to 3 h after cataract surgery (Group B: 17.84 ± 5.33 mmHg), and 20 h to 8 weeks after surgery (Group C: 13.71 ± 4.78 mmHg). The IOP values from 1 to 3 h after surgery (Group B) were significantly higher compared to both Group A ( < 0.01) and Group C ( < 0.001). Conclusions: It is suggested that POH occurring within 0 to 3 h after cataract surgery should be diagnosed as secondary glaucoma, and treatment should be performed accordingly.
白内障是一种眼睛晶状体变混浊，导致部分或完全视力丧失的疾病。超声乳化白内障吸除术（PHACO）是白内障手术中使用的一种现代外科技术。研究结果：本研究观察了31只患有白内障的犬（48只眼）在一家兽医医院接受手术后的眼压（IOP）变化。该手术包括通过PHACO摘除晶状体并植入人工晶状体（IOL）。术后高眼压（POH）定义为术后眼压为25 mmHg或更高。为了评估眼压变化，在术后1、2、3和20小时以及术后1、2、3、4和8周进行眼压测量。发现术后1小时（<0.05）、2小时（<0.01）和3小时（<0.01）时的眼压与术前相比显著更高。根据观察期将眼压测量值分为三组进行比较。对三组进行眼压测量：白内障手术前（A组：13.10±8.29 mmHg）、白内障手术后1至3小时（B组：17.84±5.33 mmHg）以及手术后20小时至8周（C组：13.71±4.78 mmHg）。手术后1至3小时（B组）的眼压值与A组（<0.01）和C组（<0.001）相比均显著更高。结论：建议将白内障手术后0至3小时内发生的POH诊断为继发性青光眼，并应相应地进行治疗。
