When that happens, your vagina might slip down out of place, causing a prolapse. 8600 Rockville Pike Because there is already a high-pressure state behind the iris due to the infusion pressure, we need to balance this pressure by increasing the pressure in front. When balanced salt solution gets directed behind the iris and pushes it forward, the act of the iris prolapsing forward usually self-corrects the pressure gradient. Reverse Trendelenberg positioning and general endotracheal anesthesia with paralytics can also mitigate posterior pressure caused by patient anatomy.

Because a prolapse can cause other problems, its important to get it checked out by your healthcare provider. Online ahead of print. Other causes include poorly dilated pupils (more exposed iris to flip up and out of the wound), hydrated vitreous (from a ruptured capsule or balanced salt solution getting pushed through the zonules; usually seen with a dispersive OVD), leaking or poor wound construction, patient Valsalva maneuver (from pain or a lid speculum that is too tight), traumatized or abnormal iris, suprachoroidal hemorrhage (entailing more to worry about than the iris), excessive retrobulbar anesthetic, and shallow anterior chambers. To solve this problem, one needs to identify the cause and then equalize or reverse this pressure gradient. If the iris has frayed in the subincisional area, the placement of one or more flexible iris retractors, one of which is located under or near the incision, helps to prevent repeated prolapse or aspiration of frayed iris tissue during surgery. Before They will do a physical exam and talk to you about any symptoms of fullness in your pelvic area or urinary incontinence (leaking pee).

Some of the most common causes are overly aggressive hydrodissection (balanced salt solution trapped behind the lens), ophthalmic viscosurgical device (OVD) behind the IOL (during IOL insertion), balanced salt solution misdirection, and intraoperative floppy iris syndrome (IFIS). This tract prevents the situation where the BSS cannot leave the eye without taking viscoelastic with it, which could result in a rapid decrease in anterior chamber pressure - a main risk factor for prolapse. Thirty-four per cent of iris prolapses were identified on the first post-operative day and 86% within 2 weeks. 2002 Jan-Feb;33(1):66-70.

Simply depressing the iris and IOL and flattening the anterior chamber will immediately neutralize the pressure gradient and the iris will return to its normal position.
