The potential risks and benefits of cataract surgery, in context of congenital aniridia (CA), are not widely understood, yet. Our purpose was to investigate the effect of lens properties on visual acuity (VA), aniridia-associated keratopathy (AAK) stage and presence of glaucoma at the Homburg Aniridia Center. CA subjects, examined at the Department of Ophthalmology of Saarland University between June 2003 and January 2022, were included. VA, slit-lamp examination, AAK grade, and glaucoma evaluation data were extracted from the medical records, from the first visit to the center. Eyes were categorized as clear lens, cataract, pseudophakic, aphakic, or subluxated lens. Patients were grouped by age (0-10, 10-20, 20-40, 40+ years). In 553 eyes of 286 CA subjects (age 19.9 ± 19.9 (0-83) years, 46.1% males), analysis revealed significant differences in VA and mean IOP (ANOVA  < 0.0001;  = 0.001, respectively) with lens status. Lens status was strongly associated with AAK Grade and glaucoma presence (  < 0.0001 for both). In age subgroups, AAK Stage was strongly associated with lens status in the 0-10 years (  < 0.001), 10-20 years (  < 0.001), and 40+ years (  = 0.02) groups and lens status was strongly associated with glaucoma presence in the 0-10 years (  = 0.003) and 20-40 years (  = 0.002) groups. AAK Stage was the most advanced in pseudophakic and aphakic eyes and presence of glaucoma was more pronounced in pseudophakic, aphakic and subluxated lens eyes. In a large population of CA, previous cataract surgery was associated with higher AAK Grade and presence of secondary glaucoma both in postoperatively pseudophakic and aphakic eyes. Our data indicate that caution is warranted with cataract surgery in congenital aniridia.
