<p>This solution contains no preservative and should not be used for more than one patient. Use only if container and seal are undamaged and solution is clear. The addition of any medication to isotonic solution may result in damage to intraocular tissue. There have been rare reports of corneal clouding or edema following ocular surgery in which isotonic solution was used as an irrigating solution. As in all surgical procedures appropriate measures should be&nbsp;taken to minimize trauma to the cornea and other ocular tissues.</p>
