Filtration blebs in corneoscleral wounds sutured with Dexon 7-0 and Dexon 8-0

In a retrospective investigation the incidence of post-operative subconjunctival filtration with bleb formation were studied in 112 eyes which had undergone cataract surgery with a corneoscleral incision sutured with braided polyglycolic acid sutures (Dexon). In 61 consecutive cataract operations sutured with Dexon 8-0 there were filtration blebs in 24 (39,3%) eyes, and in 51 consecutive cataract operations sutured with Dexon 7-0 there were filtration blebs in 11 (21,6%), eyes. Although there is a difference between the two materials, this is not statistically significant with the normal security level P less than 0.05.
