Although the rate of sight-threatening complications was about 6% for both groups, scleral-fixated posterior chamber IOLs were associated with more intraoperative and postoperative complications than angle-fixated anterior chamber IOLs, and surgery took longer. Thus, anterior chamber IOL implantation should be considered for older patients with relatively good endothelial cell counts.

The results confirm the potent mydriatic effect of 2% ibopamine, which is greater than that of either 10% phenylephrine or 1% tropicamide, as well as its ability to induce an increase in intraocular pressure when used in patients with glaucoma alone. These data support the hypothesis that the widening of the ACA induced by 2% ibopamine is due to posterior rotation of the iris plane and ciliary processes. These changes are quantitatively greater than those induced by 10% phenylephrine and 1% tropicamide and are related to the greater mydriatic effect of the drug.

Ultrasound biomicroscopy showed that filtering bleb formation was frequent in eyes having DS with RHAI but that it was not the only surgically induced IOP-lowering mechanism. Increased uveoscleral and transscleral filtration may be equally important.
