Postoperative Corneal Injuries: Incidence and Risk Factors.

Background: Previous studies of postoperative corneal injury rates relied on provider-initiated incident reports, which may underestimate the true incidence. Postoperative administration of proparacaine eye drops is used almost exclusively to diagnose corneal injury; therefore, identifying instances of administration may provide a better estimate of corneal injuries. We compared proparacaine administration versus provider-initiated reports to determine rates of corneal injury.

String Technique for Anterior Orbital Fish Hook Removal.

Removing fish hooks is a common procedure performed by many emergency department providers. There are several techniques that are commonly employed to aid in successful removal. However, when a fish hook becomes embedded within the orbit, there are limited options as to avoid damaging vital surrounding structures.

Outcomes of Cataract Surgery in Patients With Exudative Age-related Macular Degeneration and Macular Fluid.

Surgical removal of dystrophic calcification on a silicone intraocular lens in association with asteroid hyalosis.

We present a case of successful removal of late calcium deposition on the posterior surface of a silicone intraocular lens (IOL) optic in association with asteroid hyalosis using a surgical technique that included pars plana vitrectomy, a lighted pick, and a modified silicone-tipped cannula. The lighted pick provided the most efficient and complete removal of calcium deposits. Postoperatively, the dystrophic calcification was removed and the IOL optic was clear at 6 months follow-up.

Variations in Trabeculectomy and Glaucoma Drainage Device Use for the Treatment of Glaucoma in the United States.
