Blepharoptosis in RGP and PMMA hard contact lens wearers

Abstract

The majority of contact lens wearers presenting with blepharoptosis gave a history of prolonged use of hard contact lenses. One explanation for this would be the mechanisms of removal of hard contact lenses. This involves pulling the lids laterally at the lateral canthus followed by a harsh blink, which over years can lead to levator aponeurosis dehiscence. Contact lens associated ptosis is an uncommon cause of acquired ptosis across all age groups.
