The main outcome measure was predictive refraction error (PE), defined as observed refraction error \u2013 target refraction error, calculated by the SRK\/T, Haigis, and SRK II formulae. PE was measured at postoperative 1, 3, and 6 months. Simple and multiple linear regression analysis were used to evaluate factors associated with PE.Results: A total of 53 eyes of 53 patients were included. The mean PEs at postoperative 1, 3, and 6 months were all negative, implying myopic shift in all patients regardless of the intraocular lens formula used. Haigis formula showed the least myopic shift among the three formulae (p = 0.001, Friedman test). There was no significant difference in PE depending on preoperative central macular thickness (CMT) in subgroup analysis. On stepwise multiple linear regression analysis, ERM etiology (\u03b2 = 0.759, p = 0.004, SRK\/T formula; \u03b2 = 0.733, p = 0.008, Haigis formula; \u03b2 = 0.933, p &lt; 0.001, SRK II formula), preoperative anterior chamber depth (\u03b2 = \u20130.662, p = 0.013, Haigis formula; \u03b2 = \u20130.747, p = 0.003, SRK II formula), and decrease of CMT (\u03b2 = \u20130.003, p = 0.025, SRK\/T formula) were significantly associated with PE at postoperative 6 months.Conclusions: Myopic shift in PE was observed after combined phacovitrectomy for epiretinal membrane. ERM etiology, preoperative anterior chamber depth, and decrease of CMT were significantly associated with PE at postoperative 6 months. There was no difference in PE after surgery between the two groups defined by CMT (\u2265500 and &lt;500 \u03bcm).<\/jats:p>","DOI":"10.3341\/kjo.2022.0108","type":"journal-article","created":{"date-parts":[[2022,12,22]],"date-time":"2022-12-22T18:25:15Z","timestamp":1671733515000},"page":"23-30","update-policy":"https:\/\/doi.org\/10.3341\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Assessment of Risk Factors Affecting Refractive Outcomes after Phacovitrectomy for Epiretinal Membrane"],"prefix":"10.3341","volume":"37","author":[{"given":"Yu Jin","family":"Roh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joo Young","family":"Shin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tae Wan","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeeyun","family":"Ahn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1893","reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1111\/ceo.13914"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/s0161-6420(97)30190-0"},{"key":"ref3","first-page":"403","volume-title":"The epidemiology of epiretinal membranes","author":"Klein","year":"1994"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/s0002-9394(02)01972-4"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1076\/soph.18.3.132.29806"},{"key":"ref6","first-page":"1106","volume-title":"Combined phacoemulsification and pars plana vitrectomy: clear corneal versus scleral incisions: prospective randomized multicenter study","author":"Heiligenhaus","year":"2003"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1136\/bjo.87.11.1333"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1007\/s00417-005-0146-9"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1111\/aos.13572"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcrs.2013.04.012"},{"key":"ref11","first-page":"108","volume-title":"Factors influencing refractive outcomes after combined phacoemulsification and pars plana vitrectomy: results of a prospective study","author":"Jeoung","year":"2007"},{"key":"ref12","first-page":"1754","volume-title":"Accuracy of preoperative biometry in vitrectomy combined with cataract surgery for patients with epiretinal membranes and macular holes: results of a prospective controlled clinical trial","author":"Falkner-Radler","year":"2008"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.3349\/ymj.2015.56.3.805"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.3390\/jcm9113493"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.52725\/aocl.2021.20.2.55"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.3341\/jkos.2015.56.2.219"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1097\/iae.0000000000000061"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1097\/iae.0000000000002153"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1007\/s00417-015-2948-8"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1016\/s0886-3350(13)80917-0"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1007\/s00347-009-1941-1"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2010.01.018"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.3129\/i08-135"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1111\/j.1755-3768.2007.00879.x"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1016\/j.ophtha.2013.07.042"},{"key":"ref26","doi-asserted-by":"publisher","DOI":"10.1007\/s10792-014-0010-1"},{"key":"ref27","first-page":"779","volume-title":"Idiopathic and secondary epiretinal membranes: do they differ in terms of morphology?
