Cataract decreases blue light transmission. Because of the selective blue light sensitivity of the retinal ganglion cells governing circadian photoentrainment, cataract may interfere with normal sleep–wake regulation and cause sleep disturbances. The purpose was to investigate the effect of cataract surgery on circadian photoentrainment and to determine any difference between blue-blocking and neutral intraocular lenses (IOLs).

Although there are a number of benefits of electronic health records (EHR), ophthalmologists are concerned about the costs and potential loss of productivity associated with their use.1,2 The purpose of this study is to report a detailed postimplementation financial analysis of 1 practice's experience with EHR implementation.

To determine the prevalence and incidence of exudative age-related macular degeneration (AMD) in South Korea.

To compare efficacy and safety of 2 dosing regimens of intravitreal aflibercept injection (IAI) with macular laser photocoagulation for diabetic macular edema (DME).

To estimate the diagnostic accuracy and lead time gained by retinal nerve fiber layer (RNFL) thickness measurements from optical coherence tomography (OCT) for detecting glaucoma before the development of visual field defects.

To identify risk factors for multidrug-resistant Pseudomonas aeruginosa (MDR-PA) keratitis and to report clinical characteristics and outcomes of this infection.
