Aetiology was congenital (49%), uveitic (26%) and traumatic (25%). IOL position was ciliary sulcus (68%), capsular bag (18%) and scleral-fixated (14%). Glaucoma progression occurred in 16 eyes (28%), predominantly in eyes with pre-existing glaucoma (15\/21, 71%), vs 1\/36 eyes (3%) without pre-existing glaucoma (relative risk 25.7; 95%\u2009CI 3.7 to 181.0; p&lt;0.0001). Progression was most frequent in uveitic eyes (67%) and was not observed in traumatic cataract (p=0.00012). No significant association was observed between age group or IOL position and glaucoma progression.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Secondary IOL implantation is associated with a significant risk of glaucoma progression in eyes with pre-existing glaucoma but appears unlikely to induce new-onset glaucoma in eyes without prior disease.
