Pseudochalazion of the upper lid due to hard contact lens embedding -- case reports and literature review.

Two cases of pseudochalazion formation secondary to hard contact lens embedding are reported. In all previously reported cases a lump, swelling, mucopurulence, and ptosis were the most common presenting symptoms. Embedding usually occurred concave to the globe in the supratarsal region. The cases reported herein are unique in that the location of one lens was beneath the tarsal conjunctiva, and in the second case there was spontaneous release of the lens after four months of embedding.
