CompositionHydroxypropylmethylcellulose (0.3% w/v)
SALT INFORMATIONHydroxypropylmethylcellulose (0.3% w/v) TYPICAL USAGE Aid in opthalmic surgery. SIDE EFFECTS Local irritation, iritis, corneal edema. DRUG INTERACTION Aid in opthalmic surgery. MECHANISM OF ACTION Hydroxypropyl methylcellulose is a nonpyrogenic viscoelastic solution that occupies space and protects tissue. When used in anterior segment surgeries, it allows for more efficient manipulation with less trauma to the ocular tissues, such as the corneal endothelium, by maintaining a deep chamber. The viscoelastic properties of hydroxypropyl methylcellulose facilitates pushing back the vitreous face, which prevents the formation of a postoperative flat chamber.
