Forty eyes of 40 patients (13M\/27F; the median age of 74) were included in this prospective study, underwent 2.75 mm incision cataract surgery, and were followed for 30 days. Visits were scheduled at baseline before surgery (V0), the 1st (V1), the 7th (V2), and the 30th (V3) postoperative days. The main parameters estimated and analyzed with Statistica\u00ae 14.0.1 were CH, CRF, astigmatism diopter, and axis. Following the cataract surgery, the CH did not significantly change during the study visits (p = 0.109). However, there was a significant change in the CRF from baseline during the study visits (per protocol set) (p = 0.002). After a slight but insignificant increase from V0 to V1, post hoc analysis found a significant decrease in the mean CRF from V1 to V2 (p = 0.049) with no substantial change from V2 to V3. According to the post hoc analysis, the median astigmatism diopter increased significantly only from V0 to V1 (p = 0.001) and slightly but not significantly decreased to the end of the study with the achievement of a near-baseline value. The main predictors for the final astigmatism diopter (R2 = 0.898) obtained by stepwise regression analysis were its values at V0, V1, and V2 (p &lt; 0.001). The CRF at V1 was marginally significant, with a negative parameter estimate of \u22120.098303 (p = 0.0623). In conclusion, there was no correlation between preoperative CH and CRF and postoperative astigmatism using 2.75 mm incision cataract surgery. However, the final astigmatism diopter\u2019s main predictors were its baseline values before cataract surgery, the first, and the seventh postoperative days.<\/jats:p>","DOI":"10.3390\/life14060655","type":"journal-article","created":{"date-parts":[[2024,5,22]],"date-time":"2024-05-22T10:00:11Z","timestamp":1716372011000},"page":"655","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Corneal Biomechanics and Other Factors Associated with Postoperative Astigmatism after Cataract Surgery"],"prefix":"10.3390","volume":"14","author":[{"given":"Kata","family":"\u010culina","sequence":"first","affiliation":[{"name":"Eye Clinic \u201cMedi\u0107, Juki\u0107\u201d, 21000 Split, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7535-3631","authenticated-orcid":false,"given":"Martina","family":"Tomi\u0107","sequence":"additional","affiliation":[{"name":"Vuk Vrhovac University Clinic for Diabetes, Endocrinology and Metabolic Diseases, Merkur University Hospital, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4808-2968","authenticated-orcid":false,"given":"Tomislav","family":"Bulum","sequence":"additional","affiliation":[{"name":"Vuk Vrhovac University Clinic for Diabetes, Endocrinology and Metabolic Diseases, Merkur University Hospital, 10000 Zagreb, Croatia"},{"name":"School of Medicine, University of Zagreb, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-7565-2755","authenticated-orcid":false,"given":"Aleksej","family":"Medi\u0107","sequence":"additional","affiliation":[{"name":"Eye Clinic \u201cMedi\u0107, Juki\u0107\u201d, 21000 Split, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6869-3734","authenticated-orcid":false,"given":"Ivan","family":"\u0160o\u0161a","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Rijeka, 51000 Rijeka, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristina","family":"Ivani\u0161evi\u0107","sequence":"additional","affiliation":[{"name":"Ophthalmological Office \u201cAnte Vukovi\u0107\u201d, 21300 Makarska, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomislav","family":"Juki\u0107","sequence":"additional","affiliation":[{"name":"Eye Clinic \u201cMedi\u0107, Juki\u0107\u201d, 21000 Split, Croatia"},{"name":"School of Medicine, University of Zagreb, 10000 Zagreb, Croatia"},{"name":"Department of Ophthalmology, Zagreb University Hospital Center, 10000 Zagreb, Croatia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,21]]},"reference":[{"key":"ref_1","first-page":"495","article-title":"Clinical comparison analysis in surgically induced astigmatism of the total, anterior and posterior cornea after 2.2-mm versus 3.0-mm clear corneal incision cataract surgery","volume":"55","author":"Liang","year":"2019","journal-title":"Zhonghua Yan Ke Za Zhi"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"3785","DOI":"10.4103\/ijo.IJO_1627_22","article-title":"Postoperative astigmatic considerations in manual small-incision cataract surgery\u2014A review","volume":"70","author":"Pattanayak","year":"2022","journal-title":"Indian J.
