[Synthetic absorbable PDS explant for the treatment of retinal detachment]. / Explant synthétique absorbable de PDS pour le traitement du décollement de la rétine.

ABSTRACT

The following article discusses the experimental and clinical reasons for using absorbable synthetic explants in retinal surgery. We have carried out experimental studies with absorbable synthetic explants bandmade from absorbable sewing threads PG910, PGA and PDS; proving that these explants are well tolerated by the organism. Their reabsorption time is from 45 days using PG910, to 8 months using PDS; these periods are sufficient for proper anatomical healing of the retina to take place. We present 13 cases of extraction of Teflon explants after retinal detachment surgery; in none of these cases did re-detachment of the retina occur. Consequently, this induced us to introduce absorbable synthetic explants into retinal detachment surgery, using absorbable threads, having previously carried out an experimental study on rabbits. We present 10 cases of retinal detachment operated on with PDS from 95 cases operated on using absorbable synthetic explants; 100% anatomical healing of the retina was achieved. We consider this type of explant to be the ideal material for retinal detachment healing, due to the fact that its period reabsorption, being longer than those of the other explants, allows a longer indentation period.
