With interest I read the article by Harooni et al1 on the efficacy of hyaluronidase in reducing increases in intraocular pressure (IOP) related to the use of viscoelastic substances, because I have been using this method since 1991.
After cataract operations, it is generally not difficult to remove a viscoelastic substance consisting of HA by infusion or aspiration. On the other hand, if an intraocular lens was implanted into a phakic eye to correct a refractive error, removing the HA by irrigation is more difficult because the space behind the cornea is constricted.
