Randomized Controlled Trial Comparative StudySeparate and additive mydriatic effects of lidocaine hydrochloride, phenylephrine, and cyclopentolate after intracameral injection.
To assess the separate mydriatic effect of lidocaine hydrochloride (Xylocaine), cyclopentolate, and phenylephrine after intracameral injection and evaluate whether intracameral Xylocaine and phenylephrine without cyclopentolate provide sufficient pupil dilation for cataract surgery. ⋯ Xylocaine plus phenylephrine injected intracamerally gave adequate intraoperative pupil dilation in routine phacoemulsification surgery. Cyclopentolate administrated intracamerally had no immediate additive mydriatic effect to intracameral Xylocaine combined with phenylephrine.

Comparative StudyAccuracy of surrogate decision making in elective surgery.
To assess the accuracy of surrogate decision making for elective cataract surgery. ⋯ The findings suggest that current methods of decision making in elective surgery for patients unable to make autonomous decisions may be seriously flawed. This extends previous findings of inaccuracy with the substituted judgment approach to end-of-life issues to reflect elective surgical scenarios.

Case ReportsSub-Tenon's block complicated by subconjunctival cilia.
We describe an unusual case of symptomatic eyelash entrapment in the subconjunctival space following a sub-Tenon's block. This case emphasizes the need for vigilance in patients reporting a persistent foreign-body sensation following surgery with this common modality of anesthesia.

Simple test to confirm cleavage with air between Descemet's membrane and stroma during big-bubble deep anterior lamellar keratoplasty.
We describe a simple test to confirm big-bubble formation in deep anterior lamellar keratoplasty by observing the position and movements of small air bubbles injected into the anterior chamber through a limbal paracentesis. The test also allows evaluation of the extension of Descemet's membrane cleavage from the posterior stroma relative to the margins of the corneal trephination.
