Entropion of the lower eyelid was corrected in 26 eyelids of 21 patients. All patients were found to have a disinsertion of the capsulopalpebral fascia, but not Muller's muscle layer, of the lower eyelid retractors. All cases were repaired by reattaching the anterior edge of the capsulopalpebral fascia to the inferior edge of the lower tarsus combined with A horizontal eyelid tightening procedure performed at the lateral canthus. With follow-up of six to 32 months, no cases of entropion have recurred. We have found a combined procedure of horizontal eyelid tightening and repair of the capsulopalpebral fascia gives best long-term results.
