Studies suggest that intraocular irrigating solutions which are iso-osmotic with normal aqueous fluids should be used with caution in diabetic patients undergoing vitrectomy since intraoperative lens changes have been observed. There have been reports of corneal clouding or edema following ocular surgery in which BSS Sterile Irrigating Solution was used as an irrigating solution.

Irrigation or any other trauma to the corneal endothelium may result in corneal swelling or bullous keratopathy. Post-operative inflammatory reactions as well as incidents of corneal edema and corneal decompensation have been reported.
