“…The lens is a structure formed by epithelial cells that constantly generates lens fibers throughout life and, differently than what occurs in the skin tissue, old lens fibers are not loss and so, as result of the aging process, the lens become more compact and thicker, leading to loss on its transparency and to the cataract formation 22 – 24 . As published before, the cataract surgical coverage in this population was 42.1% which explain the high frequency of participants presenting cataract in this analysis 15 .…”

“…The Brazilian Amazon Region Eye Survey (BARES) is a population-based study of visual impairment and blindness among adults 45 years and older residing in both urban and rural areas in the city of Parintins 11 . Several epidemiologic aspects from BARES had been previously reported: the prevalence and causes of blindness and visual impairment for distance 12 and near 13 ; the impact of refractive correction on visual acuity 14 ; the prevalence, visual outcomes and complications of cataract surgery 15 ; and the prevalence of pterygium 16 .…”

Recently, it has been recommended that population-based studies report not only frequencies of vision impairment and blindness but also any ocular abnormalities that might lead an individual to seek for eyecare services. The current study aimed to determine prevalence of ocular findings regardless of visual acuity (VA) status in older adults from the Brazilian Amazon Region. Disturbances were grouped into: Eyelids; Anterior Segment; Posterior Segment; Increased intraocular pressure; and Overall Globe. The presence of an ocular finding was considered positive when any abnormality was noted, regardless of VA. Refractive errors were not considered. A total 2384 eligible persons were enumerated and 2041 (85.6%) examined. The prevalence of ocular disturbances in either eye was 87.0% and was associated with male gender, older age, lower education, and rural residence. Overall, main findings were pterygium, cataract, and pinguecula, occurring in 58.8%, 45.4% and 17.4%, respectively. Among individuals with 20/20 VA in both eyes, the most frequent findings were pterygium, pinguecula, and glaucoma cupping, occurring in 47.4%, 31.2% and 6.5%, respectively. The high prevalence of ocular findings observed in this population reinforces that different conditions might not immediately decrease VA but can indicate risk and/or discomfort symptoms and should be considered when planning public health ophthalmic services.

“…A previous population-based study performed in Sao Paulo in 2004 showed a burden of cataract of 8.54% in adults 50 years and older while a population-based study performed in the Amazon Region in 2014 showed a burden of cataract of 17.23% in adults 45 years and older. Moreover, the surgical coverage was 61.40% in Sao Paulo and 42.12% in the Amazon Region [11,35]. The higher burden observed in the 2014 may reflect the increasing number of cataract cases along the years.…”

“…As important as seeing the increased number of procedures along the years, it is crucial to guarantee the quality of the provided service. There is a lack of studies analyzing the cataract surgery outcomes in developing countries and these are the main indicator on treatment quality [11,26,35]. The two population-based studies performed in Sao Paulo and in the Amazon Region showed frequencies of presenting visual impairment (presenting visual acuity �20/63) of, respectively, 30.7% and 34.8% of cataractoperated eyes, significantly above the WHO recommendation of 20% or less [11,35,36].…”

“…This is a reversible condition and therefore one of the main focuses of public health policies addressing visual impairment and blindness worldwide. It has been recognized the need to increase the cataract surgical rate (annual number of cataract operations performed per million population) mainly in developing countries with extensive territory and regional discrepancies [10,11].…”

Cataract is a highly prevalent, treatable, and sight threatening condition considered one of the main focuses of public health policies addressing visual impairment and blindness towards Universal Eye Health. We aimed to investigate the trends on number of cataract surgical procedures performed through the Brazilian national health system (SUS) from 2000 to 2019 while also evaluating costs associated with it. The Brazilian Public Health System Information Database (DATASUS) was used as the primary data source for procedures including extracapsular cataract extraction (ECCE) and phacoemulsification. Trends along the years were evaluated through generalized linear models. A total of 8,424,521 cataract procedures were performed from 2000 to 2019, with a significant increase along the years from 228,145 in 2000 to 663,186 in 2019 (p<0.001), a cataract surgical procedure rate change from 13.15 to 32.28 procedures per 10,000 people. It was observed a significant increase on the number of phacoemulsification (p<0.001) and a significant decrease on the number of ECCE (p<0.001). A shift on the predominant technique has occurred between 2007 and 2008 with phacoemulsification increasing its percentual representativity from 34.3% to 69.7% of all procedures, reaching 96.1% in 2019. Phacoemulsification costs per procedure increased 30.5% from from USD$119.00 to USD$155.33 (p = 0.007) and the ECCE costs per procedure increased 29.1% from USD$78.57 to USD$101.43 (p = 0.001). There is an increasing trend of procedures related to cataract treatment performed through SUS along the 20-years period and a switch on the technique predominance from ECCE to phacoemulsification was observed after 2007. The costs associated with both techniques have increased but have not followed the country’s overall inflation. Data derived from DATASUS is important to understand the overall panorama of ocular health offered by the national health system and to provide information to guide healthcare leaders on management and planning of public health policies within the system.
