Reassurance that contact lenses safe for patients with diabetes

Patients with diabetes may experience altered tear chemistry and tear secretion as well as structural and functional changes to the corneal epithelium, endothelium and nerves. 

But reports of problems with contact lenses often concerned patients with advanced diabetic eye disease using them for extended periods, the authors said.

So long as patients did not have obvious contraindications such as signs of ocular surface disease, a history of recurrent erosions or corneal insensitivity, contact lens use should not be ruled out, they said. 

But adequate patient instruction and the use of “superior products” was advised. Contact lenses may in fact be a viable mode of refractive correction, they found.
