Very common finding especially in the first week postoperatively
May also occur following other intraocular surgeries such as corneal transplant, glaucoma and posterior chamber procedures
The folds can be visualized as dark, deep-appearing, criss-cross lines in the posterior stroma and Descemet's membrane associated with a hazy or mild loss of stromal transparency due to corneal edema
Normally, the edema will resolve over several weeks. However, the condition may be irreversible in eyes with preexisting endothelial dystrophies or low endothelial cell density
Possible causes: endothelial cell loss during surgery, anterior chamber irrigation, intraocular manipulation or mechanical trauma from surgical instruments or intraocular lenses.
Management
Postoperative evaluation is essential to rule out possible corneal endothelial trauma, Descemet's membrane tear by the surgical instruments or postoperative inflammation.
Topical corticosteroids to reduce inflammation reaction that might contribute to further endothelial damage.
