Methods: In this prospective, single-center study, 70 eyes of 70 patients undergoing cataract surgery via CCI were enrolled. Wound sealing was evaluated by measuring the GLT, defined as the duration the stromal groove remains visible after corneal hydration. GLT was categorized into five grades: \u2018water-tight\u2019 (&gt;10 s), \u2018excellent\u2019 (&gt;5 s), \u2018good\u2019 (3\u20135 s), \u2018bad\u2019 (1\u20132 s), and \u2018poor\u2019 (&lt;1 s). Intraocular pressure (IOP) was recorded at four time points: preoperatively, immediately post-surgery, 3\u20134 h postoperatively, and on postoperative day one. In select cases, anterior segment optical coherence tomography (AS-OCT) was used to confirm wound architecture. Results: All patients demonstrated a GLT longer than 5 s, corresponding to water-tight or excellent wound sealing. Mean IOP values were 16.08 \u00b1 3.61 mmHg preoperatively, 29.48 \u00b1 11.13 mmHg immediately post-surgery, 16.38 \u00b1 5.45 mmHg at 3\u20134 h, and 16.65 \u00b1 4.36 mmHg on the day after surgery. No cases of postoperative endophthalmitis, anterior chamber loss, or hypotony were observed. Conclusions: The GLT method provides a simple, objective, and effective tool for evaluating wound integrity in CCIs, ensuring optimal sealing and enhancing postoperative safety.<\/jats:p>","DOI":"10.3390\/jcm14124091","type":"journal-article","created":{"date-parts":[[2025,6,10]],"date-time":"2025-06-10T05:11:49Z","timestamp":1749532309000},"page":"4091","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Groove Loss Time: A Novel Wound Leakage Test for Sutureless Clear Corneal Cataract Wound Incision"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-5142-8334","authenticated-orcid":false,"given":"Sunjin","family":"Hwang","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Hanyang University Guri Hospital, Hanyang University College of Medicine, Guri 11923, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moonsu","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hanyang University Guri Hospital, Hanyang University College of Medicine, Guri 11923, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jooyoung","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hanyang University Guri Hospital, Hanyang University College of Medicine, Guri 11923, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8413-1929","authenticated-orcid":false,"given":"Eun Hee","family":"Hong","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hanyang University Guri Hospital, Hanyang University College of Medicine, Guri 11923, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1251-8985","authenticated-orcid":false,"given":"Yong Un","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hanyang University Guri Hospital, Hanyang University College of Medicine, Guri 11923, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min Ho","family":"Kang","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Hanyang University Guri Hospital, Hanyang University College of Medicine, Guri 11923, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1429","DOI":"10.1016\/j.jcrs.2007.04.011","article-title":"Clear corneal incision architecture in the immediate postoperative period evaluated using optical coherence tomography","volume":"33","author":"Calladine","year":"2007","journal-title":"J.
