The right eye of each subject had instillation of cyclopentolate hydrochloride 1% (Group 1) and the left eye of each subject had instillation of tropicamide 1% (Group 2). SE, intraocular pressure, and corneal topography measurements were performed before and 40\u2009min after instillation were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>In Group 1, SE, aqueous depth, anterior chamber depth, iridocorneal angle (ICA), anterior chamber volume (ACV), and pupil size (PS) values were significantly increased ( p\u2009&lt;\u20090.001, p\u2009=\u20090.01, p\u2009&lt;\u20090.001, p\u2009=\u20090.03, p\u2009&lt;\u20090.001, and p\u2009&lt;\u20090.001, respectively).

Keratometric values (K1 and K2) and central corneal thickness changed insignificantly in both groups ( p\u2009&gt;\u20090.05).

These parameters are important in intraocular lens (IOL) power calculations. PS is also important in refractive surgery and cataract surgery with multifocal IOL implantation. Although there was an insignificant difference between the agents, the effects of tropicamide on the parameters were smaller than those of cyclopentolate.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/25158414231180984","type":"journal-article","created":{"date-parts":[[2023,7,8]],"date-time":"2023-07-08T08:18:10Z","timestamp":1688804290000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Effect of cycloplegic agents (1% cyclopentolate hydrochloride and 1% tropicamide) on anterior segment parameters"],"prefix":"10.1177","volume":"15","author":[{"given":"Mustafa","family":"Duran","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Specialist of Ophthalmology, Minister of Health Hitit University Erol Ol\u00e7ok Education and Research Hospital, \u00c7orum, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7968-4876","authenticated-orcid":false,"given":"Selim","family":"Cevher","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Faculty of Medicine, Hitit University, Corum 019040, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,7,8]]},"reference":[{"key":"bibr1-25158414231180984","doi-asserted-by":"publisher","DOI":"10.1111\/cxo.12888"},{"key":"bibr2-25158414231180984","doi-asserted-by":"publisher","DOI":"10.5935\/0004-2749.20140059"},{"key":"bibr3-25158414231180984","doi-asserted-by":"publisher","DOI":"10.1016\/j.optom.2017.09.001"},{"key":"bibr4-25158414231180984","doi-asserted-by":"publisher","DOI":"10.1159\/000310758"},{"key":"bibr5-25158414231180984","doi-asserted-by":"publisher","DOI":"10.1007\/s10384-018-0612-7"},{"key":"bibr6-25158414231180984","doi-asserted-by":"publisher","DOI":"10.1097\/00006324-197804000-00003"},{"key":"bibr7-25158414231180984","doi-asserted-by":"publisher","DOI":"10.4103\/0300-1652.184065"},{"key":"bibr8-25158414231180984","first-page":"113","volume":"51","author":"Yolton DP","year":"1980","journal-title":"J Am Optometr Assoc"},{"key":"bibr9-25158414231180984","doi-asserted-by":"publisher","DOI":"10.2147\/OPTH.S291991"},{"key":"bibr10-25158414231180984","unstructured":"Ruskell GL, Bergmanson JP.
