Abstract Purpose To analyse risk factors and visual performances of glaucomatous eyes with glistening in the intra‐ocular lens ( IOL ). Methods Prospective study performed between N ovember 2010 and A pril 2011 and involving 67 consecutive glaucomatous eyes (47 patients), who previously had a phacoemulsification with a hydrophobic acrylic IOL implanted in the capsular bag. Glistening was classified in three groups of severity grade: G 0 (<50 microvacuoles per mm 2 ), G 1 (50–150 microvacuoles per mm 2 ), and G 2 (>150 microvacuoles per mm 2 ). All eyes underwent a best‐corrected visual acuity evaluation ( BCVA , Log MAR scale), a complete clinical examination, a visual field test, a contrast sensitivity evaluation and a wavefront analysis of high‐order aberrations ( HOA s) using a S hack– H artmann aberrometer. Eyes with a posterior capsular opacification and a BCVA >0.30 Log MAR were excluded. Results Twenty six eyes (38.8%) had a grade 0, 12 eyes (17.9%) a grade 1 and 29 eyes (43.3%) a grade 2 of glistening severity grade. The mean follow‐up after cataract surgery was 35.2 ± 24.2 months and was significantly higher for G 1 and G 2 groups (p < 0.001). A higher number of topical glaucoma medication were associated with a higher glistening severity grade (p < 0.05). G 1 and G 2 groups had significantly lower mean contrast sensitivity values at high spatial frequencies and significantly higher loss variance ( LV ) values of the visual field test (p < 0.05). There was no significant difference in mean BCVA between groups (p = 0.455). Conclusions In glaucomatous eyes, glistening increased with time was associated with the number of topical glaucoma medications daily instilled and altered visual performances. It should be a consideration for glaucoma patients who are more likely to develop glistening within the IOL optic.
