Implementation of a structured surgical curriculum resulted in a statistically significant reduction in sentinel event complications, even after adjusting for surgical experience.

The surgical simulator capsulorhexis module showed significant construct validity (P<.05).

A high microbiological cure rate can be achieved in eyes with fungal keratitis; however, TKP is often needed to achieve this objective. A good final visual outcome can be achieved in most cases, but multiple keratoplasty procedures may be required.

The comparable outcomes in both groups suggests that optic capture of a single-piece acrylic IOL through an anterior capsulorhexis merits consideration for IOL placement in selected cases of insufficient posterior capsule support.

Cataract surgery can become more complex when the patient cannot be positioned with their head flat on the operating table. With creative alterations to normal positioning, successful phacoemulsification can be executed.

Electrophilic trisubstituted ethylenes (TSE), halogen ring-substituted ethyl 2-cyano-1-oxo-3-phenyl-2-propenylcarbamates, RC 6 H 4 CH5 5C(CN)CONHCO 2 C 2 H 5 (where R is 3-Br, 4-Br, 3-Cl, 4-Cl, 2-F, 3-F, and 4-F) were prepared and copolymerized with styrene (ST). The monomers were synthesized by the piperidine catalyzed Knoevenagel condensation of ring-substituted benzaldehydes and N-cyanoacetylurethane, and characterized by CHN analysis, IR, 1 H, and 13 C NMR. All the ethylenes were copolymerized with ST (M 1 ) in solution with radical initiation (AIBN) at 708C. The compositions of the copolymers were calculated from nitrogen analysis and the structures were analyzed by IR, 1 H, and 13 C NMR. The order of relative reactivity (1/r 1 ) for the monomers is 2-F (3.81) . 3-Cl (1.36) . 4-Br (1.31) . 3-Br (1.13) . 4-F (0.90) . 3-F (0.63) . 4-Cl (0.37). Higher T g of the copolymers in comparison with that of polystyrene indicates decrease in chain mobility of the copolymer due to the high dipolar character of the 629 ORDER REPRINTS TSE structural unit. Gravimetric analysis indicated that the copolymers decompose in the range 303-3198C.

A healthy 11-year-old girl presented with right upper eyelid retraction since birth. An evaluation including thyroid function studies and neuroimaging was negative, and the patient was scheduled for a right levator recession to address the eyelid malposition. Intraoperatively, after the induction of inhalational general anesthesia, the patient displayed cyclic right upper eyelid retraction. Occurring in intervals of exactly 48 seconds, these cycles involved a rapid elevation of the right eyelid from a position of half-closure to a retracted position just above the superior limbus. There was no change in pupil size or eye position during these cyclic spasms, and the contralateral eyelid was unaffected. The patient underwent an uncomplicated levator recession, which improved the upper eyelid retraction. Postoperative testing, including external motility video and infrared pupillometry, demonstrated no cyclic variation in eyelid position, eye position, or pupil size in the waking state. This is a unique case of unilateral eyelid retraction with periodic spasms under conditions of anesthesia without a preexisting oculomotor paresis; it represents an unusual variation on congenital eyelid retraction and classically described cyclic oculomotor palsy.
