All participants were emmetropic (spherical equivalent refractive error within 0.50 D of emmetropia with astigmatism less than 0.75 D) and best spectacle-corrected visual acuity was 20\/20. Only the right eyes of all subjects were included for analysis. In all subjects a complete ophthalmologic examination was performed and the amplitude of accommodation (AA) was measured by two methods: method of spheres and push-up test. Optical biometry was performed using Lenstar\u00ae (Haag-Streit AG, Koeniz, Switzerland) and keratometry (KR), anterior chamber depth (corneal epithelium to lens) (ACD), lens thickness (LT), vitreous length (VL), and axial length (AL) were measured before and after cycloplegia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Mean age of the study participants was 44 \u00b1 2 years and 36 subjects (58%) were men. Mean AA was 3.29 \u00b1 1.36 D. There were statistically significant differences between ACD, LT, and AL values measured before and after cycloplegia. There was no significant correlation between AA and any biometric parameter measured by Lenstar using univariate and multivariate analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>According to this study, there seems to be no correlation between KR, ACD, LT, VL, and AL with AA in early presbyopic eyes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.5301\/ejo.5000554","type":"journal-article","created":{"date-parts":[[2015,1,30]],"date-time":"2015-01-30T05:02:33Z","timestamp":1422594153000},"page":"298-301","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Correlation between Ocular Biometry and Amplitude of Accommodation in Early Presbyopia"],"prefix":"10.1177","volume":"25","author":[{"suffix":"MD","given":"Amir","family":"Faramarzi","sequence":"first","affiliation":[{"name":"Ophthalmic Research Center and Department of Ophthalmology, Labbafinejad Medical Center, Shahid Beheshti Medical University, Tehran - Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abbas","family":"Bagheri","sequence":"additional","affiliation":[{"name":"Ophthalmic Research Center and Department of Ophthalmology, Labbafinejad Medical Center, Shahid Beheshti Medical University, Tehran - Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Farid","family":"Karimian","sequence":"additional","affiliation":[{"name":"Ophthalmic Research Center and Department of Ophthalmology, Labbafinejad Medical Center, Shahid Beheshti Medical University, Tehran - Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Halimeh","family":"Shaianfar","sequence":"additional","affiliation":[{"name":"Ophthalmic Research Center and Department of Ophthalmology, Labbafinejad Medical Center, Shahid Beheshti Medical University, Tehran - Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad Reza","family":"Razzaghi","sequence":"additional","affiliation":[{"name":"Ophthalmic Research Center and Department of Ophthalmology, Labbafinejad Medical Center, Shahid Beheshti Medical University, Tehran - Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shahin","family":"Yazdani","sequence":"additional","affiliation":[{"name":"Ophthalmic Research Center and Department of Ophthalmology, Labbafinejad Medical Center, Shahid Beheshti Medical University, Tehran - Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2015,1,27]]},"reference":[{"key":"bibr1-ejo.5000554","doi-asserted-by":"crossref","unstructured":"von HelmholtzH Treatise on Physiological Optics, Vol. I, translated from the 3\n                      rd\n                      German edition by J.P.C.
