Methods: Refractive prediction error was defined as the difference in spherical equivalent between the predicted value using the Barrett Universal II formula and the actual value obtained at postoperative one month. Forty-eight eyes that had undergone phacotrabeculectomy (19 eyes, open-angle glaucoma; 29 eyes, angle-closure glaucoma) were matched with 48 eyes that had undergone phacoemulsification by age, average keratometry value and axial length (AL), and their prediction errors were compared. The factors associated with prediction errors were analyzed by multivariable regression analyses. Results: The phacotrabeculectomy group showed a larger absolute prediction error than the phacoemulsification group (0.51 \u00b1 0.37 Diopters vs. 0.38 \u00b1 0.22 Diopters, p = 0.033). Larger absolute prediction error was associated with longer AL (p = 0.010) and higher intraocular pressure (IOP) difference (p = 0.012). Hyperopic shift (prediction error &gt; 0) was associated with shallower preoperative anterior chamber depth (ACD) (p = 0.024) and larger IOP difference (p = 0.031). In the phacotrabeculectomy group, the prediction error was inversely correlated with AL: long eyes showed myopic shift and short eyes hyperopic shift (p = 0.002). Conclusions: Surgeons should be aware of the possibility of worse refractive outcomes when planning phacotrabeculectomy, especially in eyes with high preoperative IOP, shallow ACD, and\/or extreme AL.<\/jats:p>","DOI":"10.3390\/jcm12175706","type":"journal-article","created":{"date-parts":[[2023,9,1]],"date-time":"2023-09-01T09:12:22Z","timestamp":1693559542000},"page":"5706","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Factors Associated with Refractive Prediction Error after Phacotrabeculectomy"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3156-7638","authenticated-orcid":false,"given":"Jung Hye","family":"Shin","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Seoul National University College of Medicine, Seoul 07061, Republic of Korea"},{"name":"Department of Ophthalmology, Seoul National University Hospital, Seoul 07061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seok Hwan","family":"Kim","sequence":"additional","affiliation":[{"name":"The One Seoul Eye Clinic, Seoul 06027, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sohee","family":"Oh","sequence":"additional","affiliation":[{"name":"Department of Biostatistics, Seoul National University Boramae Medical Center, Seoul 07061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4692-3164","authenticated-orcid":false,"given":"Kyoung Min","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Seoul National University College of Medicine, Seoul 07061, Republic of Korea"},{"name":"Department of Ophthalmology, Seoul National University Boramae Medical Center, Seoul 07061, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e144","DOI":"10.1016\/S2214-109X(20)30489-7","article-title":"Causes of blindness and vision impairment in 2020 and trends over 30 years, and prevalence of avoidable blindness in relation to vision 2020: The right to sight: An analysis for the global burden of disease study","volume":"9","author":"Steinmetz","year":"2021","journal-title":"Lancet Glob.
