[Corneal perforation due to 'lost' contact lenses]. / Corneaperforatie door 'zoekgeraakte' contactlenzen.

ABSTRACT

An 87-year-old woman with Alzheimer's disease was referred to our eye clinic with a large corneal perforation of her right eye. On further examination a total of 15 contact lenses were found under the upper eyelid of her right eye; several lenses were also found in her left eye. During further evaluation we learned that our patient had experienced severe, recurrent and painful blepharoconjunctivitis for the past 3 years, for which she had consulted several ophthalmologists and other medical practitioners. The last time our patient had inserted a contact lens was more than 3 years previously. We therefore concluded that the retained contact lenses had caused an infectious ulcer which led to a corneal perforation. The patient underwent a perforating keratoplasty, which restored the eyesight in her right eye. Removal of the retained contact lenses gave our patient relief from her severe chronic eye pain.
