Since controversy remains in the accuracy of IOL power calculation formulas, both traditional and network meta-analysis on formula accuracy were conducted in patients with primary angle-closure conditions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec002\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A comprehensive literature search was conducted through Aug 2022, focusing on studies on intraocular lens power calculation in primary angle-closure (PAC) and primary angle-closure glaucoma (PACG). A systemic review and network meta-analysis was performed. Quality of studies were assessed. Primary outcomes were the mean absolute errors (MAE) and the percentages of eyes with a prediction error within \u00b10.50 diopiters (D) or \u00b11.00 D (% \u00b10.50\/1.00 D) by different formulas.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec003\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Six retrospective studies involving 419 eyes and 8 formulas (Barrett Universal II, Kane, SRK\/T, Hoffer Q, Haigis, Holladay I, RBF 3.0 and LSF) were included. SRK\/T was used as a reference as it had been investigated in all the studies included. Direct comparison showed that none of the involved formula outperformed or was defeated by SRK\/T significantly in terms of either MAE or % \u00b10.50\/1.00 D (all\n                      <jats:italic>P<\/jats:italic>\n                      &gt;0.05).
