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 (p &lt; 0.05), 2 (p &lt; 0.01), and 3 (p &lt; 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 \u00b1 8.29 mmHg), 1 to 3 h after cataract surgery (Group B: 17.84 \u00b1 5.33 mmHg), and 20 h to 8 weeks after surgery (Group C: 13.71 \u00b1 4.78 mmHg). The IOP values from 1 to 3 h after surgery (Group B) were significantly higher compared to both Group A (p &lt; 0.01) and Group C (p &lt; 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.<\/jats:p>","DOI":"10.3390\/ani15030301","type":"journal-article","created":{"date-parts":[[2025,1,22]],"date-time":"2025-01-22T03:40:17Z","timestamp":1737517217000},"page":"301","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Development of Postoperative Ocular Hypertension After Phacoemulsification for Removal of Cataracts in Dogs"],"prefix":"10.3390","volume":"15","author":[{"given":"Myeong-Gon","family":"Kang","sequence":"first","affiliation":[{"name":"Hangang Animal Medical Center, Namyangjusi 12126, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8976-2316","authenticated-orcid":false,"given":"Chung-Hui","family":"Kim","sequence":"additional","affiliation":[{"name":"Institute of Animal Medicine, College of Veterinary Medicine, Gyeongsang National University, Jinju 52828, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0450-0048","authenticated-orcid":false,"given":"Shin-Ho","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Companion Animal Health, Tongmyong University, Busan 48520, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae-Hyeon","family":"Cho","sequence":"additional","affiliation":[{"name":"Institute of Animal Medicine, College of Veterinary Medicine, Gyeongsang National University, Jinju 52828, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,1,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"101","DOI":"10.22271\/veterinary.2024.v9.i2b.1181","article-title":"Successful management of cataracts in dogs by phacoemulsification with IOL implantation: Review of two cases","volume":"9","author":"Tripathi","year":"2024","journal-title":"Int.
