Embedded hard contact lens: reports of a case.

Contact lens migration into the upper eye lid with resultant lid mass is a rare complication of hard contact lens wear. We present a case in which a cosmetically unacceptable upper lid mass was the chief problem. The patient had switched to soft contact lenses and tolerated them well for about 13 months. From computed tomographic scan pictures and the keratoscopic change, surgical exploration through the opening of a discharging sinus in the upper forniceal area delivered a 8 x 8 mm hard contact lens and a flux of tenacious mucoid discharge. Double eversion of the upper tarsus, which was advised by Green in 1963, was the most important technique in reaching the correct diagnosis, and it should be stressed again on examining patients with a history of displaced hard contact lens.
