“…A higher prevalence was also associated with female gender in first generation and with presence of hypertension in second generation immigrants. This is consistent with evidence from a previous study in rural India which reported associations of female gender and arterial hypertension along with age and diabetes with higher cataract surgery rate [18]. In contrast, except higher levels of education (polytechnic and university) in first generation immigrants, none of the socioeconomic variables had any influence on the prevalence of cataract surgery among both the generations.…”

“…The magnitude of under-corrected refractive error in our study was higher than that reported in CIEMS (41.8%) [18] but lower than that reported in SiMES (60%) [22]. In our study, 10.9% of all the pseudophakic eyes had post-operative VI.…”

“…The age-standardized rate of cataract surgery in Indians living in Singapore (9.7%) was twice as higher as those in rural Central India (4.7%) [18], similar to those reported in urban India (10.5%) [19] but lower than those reported in a study done in Navsari in Gujarat in 2009 [20] and recent Andhra Pradesh Study in 2012 [21] which showed a prevalence of 17.6% and 15.4% respectively ( Table 5 ). …”

ObjectiveTo determine the prevalence of cataract surgery and factors associated with post-surgical visual outcomes in migrant Indians living in Singapore.Research Design and MethodsWe conducted a population-based study in 3,400 Indian immigrants residing in Singapore−the Singapore Indian Eye Study (SINDI). All participants underwent comprehensive medical eye examination and a standardized interview. Post-operative visual impairment (VI) was defined as best-corrected or presenting visual acuity (BCVA or PVA) of 20/60 or worse.ResultsThe age- and gender-standardized prevalence of cataract surgery was 9.7% (95% confidence interval [CI]: 8.9%, 10.7%) in Singapore resident Indians. Post-operative VI defined by BCVA occurred in 10.9% eyes (87/795). The main causes of post-operative VI were diabetic retinopathy (20.7%), posterior capsular opacification (18.4%), and age-related macular degeneration (12.6%). Undercorrected refractive error doubled the prevalence of post-operative VI when PVA was used.ConclusionsThe rate of cataract surgery is about 10% in Indian residents in Singapore. Socioeconomic variables and migration had no significant impact on the prevalence of cataract surgery. Diabetic retinopathy was a major cause of post-operative VI in migrant Indians living in Singapore. Uncorrected postoperative refractive error remains an efficient way to improve vision.

“…The prevalence of pseudophakia in our cohort is similar to that reported in other regions of the world: e.g., the Singapore Malay Eye Study (4.7%) [4], the Beaver Dam Eye Study in Wisconsin (3.1%) [16], the Australian Blue Mountains Eye Study (6.0%) [17], the Barbados Eye Study (3.0%) [18] and the Central India Eye and Medical Study (5.0%) [7]; however, other Indian studies of urban regions have reported figures as high as 9.4% [9,19]. In China, the prevalence of pseudophakia is lower, as reported in the Beijing Eye Study 2006 [20] and 2009 [5] and the China Nine-Province Survey [10].…”

Cataract surgery is the most frequently performed surgical procedure worldwide. We aim to determine the prevalence of having implanted an artificial lens (pseudophakia) and of no lens (aphakia) and to compare visual function.As part of the Gutenberg Health study, a population-based cross-sectional study was conducted in Germany. An ophthalmological examination including slit-lamp examination was conducted. Prevalence including 95% confidential intervals were calculated and analyses were conducted for systemic and ocular associated factors with pseudophakia using multivariable logistic regression models. Vision-related quality of life was assessed using a standardized questionnaire and Rasch transformation.14,696 people were included. Of these, 1.55% [1.36%–1.77%] had unilateral pseudophakia and 3.08% [2.81%-3.37%] had bilateral pseudophakia. Unilateral aphakia was present in 21 people and bilateral aphakia in 2 people. Pseudophakia was independently associated with age, higher body weight and lower body height, diabetes and smoking. Vision-related quality of life values were similar for those with bilateral phakia and pseudophakia but were lower for those with unilateral pseudophakia.The pseudophakia status is related to several cardiovascular risk factors, indicating a relationship to an aging effect that causes premature lens opacification. Bilateral pseudophakia can almost imitate the physiological condition of phakia except for the need to use glasses.
