Abstract
In 115 consecutive cataract extractions with implantation of artifacial lens, a clinical evaluation of absorbable sutures, polyglactin (910) (Vicryl 7-0) and polyglycolic acid (Dexon 8-0) in corneolimbal incision, was performed. The corneolimbal wounds were closed by continuous suture technique with 1 double loop knot at 12 o''clock and 5-6 loops on each side of the 12 o''clock knot. The suture had disappeared after 8 wk in 95% of the eyes. Two mo. after operation, the visual acuity, the power of corneal astigmatism and astigmatic orientation remained unchanged in the Vicryl and the Dexon sutured group. This provided effectuation of early full prescription of glasses. Most complications in this material were suture independent and appeared during the early postoperative period. In only 1 eye, wound-closure was inadequate. Shallow anterior chamber and hypotonia of short duration occurred in 5 eyes. Of these patients, 4 developed corneal dystrophy. In the Vicryl sutured group, suture reactions took place in 87% of the eyes; with dexon suture, no such reaction appeared. The use of absorbable sutures in corneolimbal incision technique implies several surgical advantages and is apparently safe.
