Materials and Methods: Transverse compression load to achieve lens flexion and static Young\u2019s modulus were measured in H-ICLs and IPCLs using designated equipment. Load was measured both with and without restraining the optic section of the lenses. Adhesion of iHLEC-NY2 cells to the lens surfaces was examined using phase-contrast microscopy, and cell proliferation activity was evaluated using WST-8 assay. Results: The H-ICL showed a greater tendency for transverse compression load compared to IPCL, while the IPCL showed a higher Young\u2019s modulus with respect to the force exerted on the center of the anterior surface of the optic section. The joint between the optic section and haptic support in the IPCL was found to mitigate the effects of transverse compression load. Both lens types showed minimal cell adhesion. Conclusions: Our findings indicate that H-ICLs and IPCLs exhibit distinct physical properties and adhesive characteristics. The IPCL demonstrated higher Young\u2019s modulus and unique structural features, while the H-ICL required greater transverse compression load to achieve the flexion required to tuck the haptic supports into place behind the iris to fix the lens. The observed cell non-adhesive properties for both lens types are promising in terms of reducing complications related to cell adhesion. However, further investigation and long-term observation of IPCL are warranted to assess its stability and potential impact on the iris. These findings contribute to a better understanding of the performance and potential applications of H-ICLs and IPCLs in ophthalmology.<\/jats:p>","DOI":"10.3390\/medicina59071282","type":"journal-article","created":{"date-parts":[[2023,7,11]],"date-time":"2023-07-11T01:40:02Z","timestamp":1689039602000},"page":"1282","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Flexural and Cell Adhesion Characteristic of Phakic Implantable Lenses"],"prefix":"10.3390","volume":"59","author":[{"given":"Kazuo","family":"Ichikawa","sequence":"first","affiliation":[{"name":"Chukyo Eye Clinic, Nagoya 456-0032, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kei","family":"Ichikawa","sequence":"additional","affiliation":[{"name":"Chukyo Eye Clinic, Nagoya 456-0032, Aichi, Japan"},{"name":"General Aoyama Hospital, Toyokawa 441-0103, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9659-3204","authenticated-orcid":false,"given":"Naoki","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Support Office for Bioresource Research, Translational Research Headquarters, Fujita Health University, Toyoake 470-1192, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rie","family":"Horai","sequence":"additional","affiliation":[{"name":"Chukyo Eye Clinic, Nagoya 456-0032, Aichi, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1051","DOI":"10.1097\/ICO.0000000000000171","article-title":"Screening of Refractive Surgery Candidates for LASIK and PRK","volume":"33","author":"Torricelli","year":"2014","journal-title":"Cornea"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1111\/aos.12385","article-title":"Past and present of corneal refractive surgery: A retrospective study of long-term results after photorefractive keratectomy and a prospective study of refractive lenticule extraction","volume":"92","author":"Vestergaard","year":"2014","journal-title":"Acta Ophthalmol."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"1579","DOI":"10.1016\/j.jcrs.2016.08.025","article-title":"Myopia correction with transepithelial photorefractive keratectomy versus femtosecond\u2212assisted laser in situ keratomileusis: One-year case-matched analysis","volume":"42","author":"Luger","year":"2016","journal-title":"J.
