An experimental study was performed to evaluate quantitatively the effect of cautery on the tensile strength of sutures commonly used in strabismus surgery. This in vitro study was conducted in a controlled fashion using 6-0 polyglactin 910 suture, two different forms of cautery, and a precision digital force gauge. The results suggest that thermal electrocautery with a wire tip can substantially weaken or break 6-0 polyglactin threads only if direct contact is made, but bipolar cautery at typical ophthalmic surgical settings does not.
