To report on the changes in the natural crystalline lens in primary congenital glaucoma (PCG) eyes that had undergone previous combined angle-filtering surgery with antimetabolites.The pediatric ophthalmology unit of the ophthalmology department of Alexandria Main University Hospital.A retrospective chart review.A retrospective chart review of patients presenting with and operated (by combined angle-filtering surgery with antimetabolites) for PCG in the period from 2005 to 2018. Any lens pathology was noted as well as the management and the outcome.The records of 422 children (613 eyes) were reviewed. Lens pathology was noted in 54 (8.8%) eyes. Abnormalities in lens clarity (cataract) were detected in 31 (56%) eyes, and abnormalities in lens position (subluxation) were detected in 24 (44%) eyes. Management options included observation (in 28 eyes), lensectomy for aphakia (in 14 eyes), lensectomy with in the bag intraocular lens (IOL) implantation (in 11 eyes), and lensectomy with iris-fixated IOL (in 1 eye). Elevation of intraocular pressure (IOP) occurred in only 4 eyes (of 26 operated eyes, 15.3%) after lens extraction.Changes in the natural crystalline lens clarity and/or position occurred in 8.8% (54 of 613) of PCG eyes operated by combined angle-filtering surgery with antimetabolites. Lens extraction was a relatively safe procedure with only 15% (4 of 26) of eyes suffering an elevation of IOP after lens extraction.
