However, the use of non-absorbable sutures in these procedures poses significant challenges. Indeed, unequal tension between the various stitches can lead to deformations of the cornea or lens and consequently to problems such as post-operative astigmatism or anisometropia. To overcome these problems, sutures with improved closure via a highly stretchable behaviour together with an excellent elastic return are a credible solution. Accordingly, to widen the plethora of superelastic polymeric materials, in the present study a novel solution deriving from two furan-based polyesters, poly(pentamethylene furanoate), PPeF, and poly(hexamethylene furanoate), PHF, was successfully obtained. Of note, these homopolymers are also entirely derived from sustainable sources. The two homopolymers were physically and chemically mixed to obtain copolymers with different block lengths, which were characterised from molecular, thermal, mechanical, and surface wettability points of view, showing interesting properties which were easily modulated as a function of block length. Lastly, all the materials showed good stability over time and cell viability and, for some of them, a great mechanical recovery upon deformation was also observed.<\/jats:p>","DOI":"10.3390\/polym17233220","type":"journal-article","created":{"date-parts":[[2025,12,3]],"date-time":"2025-12-03T10:34:01Z","timestamp":1764758041000},"page":"3220","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Novel Superelastic Polyesters Based on 2,5-Furandicarboxylic Acid for Potential Use in Ophthalmic Surgery"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-5186-3064","authenticated-orcid":false,"given":"Arianna","family":"Palumbo","sequence":"first","affiliation":[{"name":"Department of Civil, Chemical, Environmental and Materials Engineering (DICAM), University of Bologna, Via Terracini 28, 40131 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2079-5261","authenticated-orcid":false,"given":"Gloria","family":"Astolfi","sequence":"additional","affiliation":[{"name":"Ophthalmology Unit, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), Alma Mater Studiorum Universit\u00e0 di Bologna, 40126 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6879-2989","authenticated-orcid":false,"given":"Giulia","family":"Guidotti","sequence":"additional","affiliation":[{"name":"Department of Civil, Chemical, Environmental and Materials Engineering (DICAM), University of Bologna, Via Terracini 28, 40131 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3646-9612","authenticated-orcid":false,"given":"Michelina","family":"Soccio","sequence":"additional","affiliation":[{"name":"Department of Civil, Chemical, Environmental and Materials Engineering (DICAM), University of Bologna, Via Terracini 28, 40131 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3754-0273","authenticated-orcid":false,"given":"Elisa","family":"Boanini","sequence":"additional","affiliation":[{"name":"Department of Chemistry \u201cGiacomo Ciamician\u201d, University of Bologna, Via Gobetti 85, 40129 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2951-5337","authenticated-orcid":false,"given":"Piera","family":"Versura","sequence":"additional","affiliation":[{"name":"Ophthalmology Unit, Dipartimento di Scienze Mediche e Chirurgiche (DIMEC), Alma Mater Studiorum Universit\u00e0 di Bologna, 40126 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7976-2934","authenticated-orcid":false,"given":"Nadia","family":"Lotti","sequence":"additional","affiliation":[{"name":"Department of Civil, Chemical, Environmental and Materials Engineering (DICAM), University of Bologna, Via Terracini 28, 40131 Bologna, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"511","DOI":"10.1016\/S0966-9795(98)00070-3","article-title":"Recent Developments in the Research of Shape Memory Alloys","volume":"7","author":"Otsuka","year":"1999","journal-title":"Intermetallics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"54","DOI":"10.1016\/S1369-7021(10)70128-0","article-title":"Shape Memory Materials","volume":"13","author":"Huang","year":"2010","journal-title":"Mater.
