Purpose of review To review the previous year's literature related to prevalence of blindness in general, blindness due to cataract, cataract surgical coverage (CSC) and cataract surgical rates (CSRs). Recent findings Cataracts are the major cause of blindness and visual impairment in developing countries and contributes to more than 90% of the total disability adjusted life years. This review shows that coverage continues to be a problem in many countries, especially for the female population… 
The global state of cataract blindness
Cost, an insufficient number of ophthalmologists, and low government funding remain significant barriers but investment in further eye care infrastructure and training of additional ophthalnologists would improve the current situation.
Commentary on ten-year incidence of cataract surgery in urban southern China: the Liwan Eye Study
Commentary on Ten-Year Incidence of Cataract Surgery in Urban Southern China: The Liwan Eye Study is a timely one, as it serves to investigate the incidence of cataract surgery of Liwan district—and old town of Guangzhou City—as well as the accessibility of the very crucial healthcare intervention of catARact surgery.

Prevalence of Age-Related Cataract and Cataract Surgery in a Chinese Adult Population: The Taizhou Eye Study.
The high prevalence of cataract and high rate of VI from ARC in the adult Chinese population remains a severe public health problem and poor visual outcomes were frequent.
Association of Sex With the Global Burden of Cataract
The findings may enhance public awareness of sexual differences in global cataract burden and emphasize the importance of making sex-sensitive health policy to manage global vision loss caused by cataracts.


Cataract surgery for the developing world
Manual small incision extracapsular cataract surgery is significantly faster, less expensive and requires less technology than phacoemulsification, and may be the preferred technique for cataracts surgery in the developing world.
Cataract surgical coverage remains lower in women
It is estimated that blindness and severe visual impairment from cataract could be reduced by around 11% in the low- and middle-income countries if women were to receiveCataract surgery at the same rate as men.

Inequity in access to cataract surgery between men and women in Botswana has contributed to the higher prevalence of cataracts-related blindness in women.
Rapid assessment of avoidable blindness.
The Rapid Assessment of Avoidable Blindness (RAAB) has been developed as a simple and rapid survey methodology that can provide data on the prevalence and causes of blindness to design and monitor eye care programmes in the surveyed area.

Gender and use of cataract surgical services in developing countries.
Closing the gender gap could thus significantly decrease the prevalence of cataract blindness, and gender-sensitive intervention programmes are needed to improveCataract surgical coverage among females.
