When assessing a cataract patient, either in general optometric practice or in a hospital cataract clinic, it is important to diagnose FED early to help in surgical planning and providing perioperative counselling to the patient regarding the risk of corneal oedema and possible corneal transplant soon after cataract surgery if corneal decompensation occurs.
We present the case of a patient with a bee sting in cornea without retention of the stinger, who developed corneal decompensation and opacification of the lens as a side effect of the poison.
Patients with DM, hypertension, history of previous intraocular surgery or ocular trauma, corneal or conjunctival irritation, history of chemical trauma, uveitis, known corneal degeneration, dystrophies, opacity, high myopia, pregnant or lactating women, contact lens wearer, dry eye, and family history of corneal decompensation were excluded.

Corneal decompensation can also occur after RLE surgery, particularly if the patient has a pre-existing endothelial dystrophy with a large number of guttatae.
8) It is impossible to quantify the risk of corneal decompensation in these cases due to multiple variables such as endothelial cell health, density and nature of the cataract, surgeon skill, patient expectations and so on.
