Other health uses include medical imaging and vision correction surgery. Eye surgeons use lasers in LASIK operations to reshape the cornea, which covers the lens of the eye. The reshaped cornea corrects the patient’s bad eyesight so he or she does not have to wear glasses or other corrective lenses.

The operation moves the ileum closer to the pancreas, the organ that makes the insulin we need to process sugar into energy. A digestive hormone in the transposed intestine stimulates the pancreas to secrete more insulin, so diabetics don't need to take it artificially. Ileum transposition also corrects insulin resistance in Type 2 diabetics, according to Erik Wilson, who performs bariatric surgery at the University of Texas Houston.
