This study measured the refractive power profiles of multifocal soft contact lenses (MFCLs) currently used or that have the potential for use in myopia control using high spatial resolution aberrometry. The instrument's repeatability for determining MFCLs power profiles was also assessed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>\n                      The power profiles of 10 MFCLs of various designs (centre\u2010distance, centre\u2010near and extended depth of focus) were measured using the Lambda\u2010X NIMO\n                      <jats:sup>EVO<\/jats:sup>\n                      , a phase shifting Schlieren\u2010based device.

There were variations in the chord position of the distance and near correction zones, rate of power transitions and calculated maximum add between the MFCLs which did not depend on lens design. For half of the MFCLs, the power profile shape was inconsistent between different nominal back vertex powers of the same design.

This is likely due to the small number of parameters used to define lens power characteristics. Eye health care practitioners should be aware of potential differences in power profiles between different MFCLs, which will impact the retinal defocus introduced during lens wear and the wearer's visual experience.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/opo.13345","type":"journal-article","created":{"date-parts":[[2024,5,31]],"date-time":"2024-05-31T06:42:07Z","timestamp":1717137727000},"page":"1202-1214","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Refractive power profiles of commercially available soft multifocal contact lenses for myopia control"],"prefix":"10.1007","volume":"44","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5647-9346","authenticated-orcid":false,"given":"Rebecca M.","family":"Dang","sequence":"first","affiliation":[{"name":"School of Optometry and Vision Science UNSW Sydney  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8342-9915","authenticated-orcid":false,"given":"Klaus","family":"Ehrmann","sequence":"additional","affiliation":[{"name":"School of Optometry and Vision Science UNSW Sydney  Sydney New South Wales Australia"},{"name":"Nthalmic Pty Ltd  Botany New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1351-0072","authenticated-orcid":false,"given":"Isabelle","family":"Jalbert","sequence":"additional","affiliation":[{"name":"School of Optometry and Vision Science UNSW Sydney  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4151-0384","authenticated-orcid":false,"given":"Alex","family":"Hui","sequence":"additional","affiliation":[{"name":"School of Optometry and Vision Science UNSW Sydney  Sydney New South Wales Australia"},{"name":"Centre for Ocular Research and Education University of Waterloo  Waterloo Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3969-2871","authenticated-orcid":false,"given":"Pauline","family":"Kang","sequence":"additional","affiliation":[{"name":"School of Optometry and Vision Science UNSW Sydney  Sydney New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,5,31]]},"reference":[{"key":"e_1_2_12_2_1","doi-asserted-by":"crossref","DOI":"10.1167\/iovs.18-25977","article-title":"IMI\u2014clinical management guidelines report","volume":"60","author":"Gifford KL","year":"2019","journal-title":"Invest Opthalmol Vis Sci"},{"key":"e_1_2_12_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/1120672121998960"},{"key":"e_1_2_12_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD014758.pub2"},{"key":"e_1_2_12_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/0042-6989(94)00233-C"},{"key":"e_1_2_12_6_1","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.12-9822"},{"key":"e_1_2_12_7_1","doi-asserted-by":"publisher","DOI":"10.1167\/iovs.10-5716"},{"key":"e_1_2_12_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.exer.2012.11.019"},{"key":"e_1_2_12_9_1","doi-asserted-by":"publisher","DOI":"10.1097\/OPX.0000000000000998"},{"key":"e_1_2_12_10_1","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2020.10834"},{"key":"e_1_2_12_11_1","doi-asserted-by":"publisher","DOI":"10.1097\/OPX.0000000000001410"},{"key":"e_1_2_12_12_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00417-018-3906-z"},{"key":"e_1_2_12_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/opo.12621"},{"key":"e_1_2_12_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/OPX.0000000000001753"},{"key":"e_1_2_12_15_1","article-title":"Comparing distance\u2010center and near\u2010center multifocal soft contact lenses for myopia control","volume":"63","author":"Singh S","year":"2022","journal-title":"Invest Ophthalmol Vis Sci"},{"key":"e_1_2_12_16_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.optom.2018.11.002"},{"key":"e_1_2_12_17_1","doi-asserted-by":"publisher","DOI":"10.1097\/OPX.0b013e3182990878"},{"key":"e_1_2_12_18_1","doi-asserted-by":"publisher","DOI":"10.1111\/opo.12332"},{"key":"e_1_2_12_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1888-4296(11)70035-8"},{"key":"e_1_2_12_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtos.2023.04.010"},{"key":"e_1_2_12_21_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.clae.2020.11.015"},{"key":"e_1_2_12_22_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjophthalmol-2013-303914"},{"key":"e_1_2_12_23_1","unstructured":"International Organisation for Standardisation.Ophthalmic optics\u2014contact lenses\u2014part 3: measurement methods (ISO 18369\u20103:2017). 2017.\u00a0[cited 2023 Apr 8].
