Late complications of 7-0 polyglycolic (Dexon) sutures in cataract surgery.

The late complications of corneo-scleral wound healing after the 15th postoperative day were recorded in 108 routine adult cataract operations using 7-0 polyglycolic acid (Dexon) sutures and compared with 80 routine adult cataract operations using 9-0 monofilament nylon (9-10 Ethilon Nylon) sutures. In 37 eyes of the 7-0 Dexon group filtrating blebs, gaping of the corneoscleral wound, anterior chamber collapse, or decrease in the intraocular pressure were observed compared with one filtrating bleb in the 9-0 nylon group. The majority of late complications occurred 22 to 42 days after surgery. Ten filtrating blebs remained after a 5 months' follow-up period. The most probable cause of the late complications in corneo-scleral wound healing was discussed.
