If a surgeon is having difficulty closing sclerotomies at the end of a posterior capsulectomy, which medication should be requested?

In the context of a posterior capsulectomy, if a surgeon encounters challenges with closing sclerotomies, the medication that would be most beneficial is mannitol. Mannitol is an osmotic diuretic that can induce temporary transient expansion of the anterior chamber. It can help facilitate the stabilization and positioning of the eye structures during surgery. When excess fluid or swelling is present, mannitol can reduce intraocular pressure and improve visualization, making it easier for the surgeon to perform delicate procedures such as suturing sclerotomies.

Viscoat, although often used as a viscoelastic agent to maintain space during ophthalmic surgeries, would not directly address the issue of closing sclerotomies. Hyaluronidase is an enzyme that breaks down hyaluronic acid, which is not relevant in the context of the closure of these specific surgical incisions. Prednisolone, a corticosteroid, is typically used to reduce inflammation rather than to assist in closing incisions. Overall, mannitol's properties make it the appropriate choice in this surgical scenario.
