To assess resident surgical experience in vitreoretinal surgery (VRS) in the United States. ⋯ This self-reported electronic survey of third-year residents suggested that VRS experience at ACGME-accredited programs as primary surgeon was suboptimal for surgeries. A modest majority of residents reported comfort and satisfaction with VRS training for surgery, but a majority was satisfied and had adequate experience with office procedures such as intravitreal injection and laser treatment. Unfortunately, the majority of residents were unaware of the actual numeric ACGME VRS requirements for ophthalmology residency programs.

To report the immediate postoperative complications and the 6- and 12-month clinical results in a large series of cases undergoing the new triple-procedure Descemet's stripping automated endothelial keratoplasty (DSAEK) and concurrent cataract surgery. ⋯ The new triple-procedure DSAEK combined with cataract surgery provides rapid visual recovery and allows selection of an appropriate intraocular lens. Dislocations are rare (1.8%) and primary graft failure did not occur.

Comparative Study
Outcomes of therapeutic deep lamellar keratoplasty and penetrating keratoplasty for advanced infectious keratitis: a comparative study.
To compare the therapeutic success, visual outcomes, complications, and graft survival rates of therapeutic deep anterior lamellar keratoplasty (TDALK) and therapeutic penetrating keratoplasty (TPK) for advanced infectious keratitis. ⋯ For medically unresponsive infectious keratitis, TDALK may be considered instead of TPK yielding similar graft survival, without an increased risk of disease recurrence.

To determine the risk factors for intraoperative complications in resident-performed phacoemulsification surgery and the effect of complications on postoperative visual acuity. ⋯ Residents performing phacoemulsification surgery achieved a low overall rate of major complications. However, specific features of cataracts, such as mature nuclei and zonular pathology, carried increased intraoperative risk. Anticipating risk may help to decrease surgical complications further and to counsel patients appropriately.

Multicenter Study
Prevalence of diabetic retinopathy in rural China: the Handan Eye Study.
To describe the age- and gender-specific prevalence, characteristics, and severity of diabetic retinopathy (DR) in a rural population in northern China. ⋯ Our study reports a high prevalence of DR among adults 30 years and older with diabetes in rural China. On the basis of estimates obtained from our study, we projected that in rural China, 21.1 million persons aged 30+ years have diabetes and 9.2 million have DR, including 1.3 million with vision-threatening DR. There is a pressing need for appropriate screening and management of diabetes and its complications in rural China.
