Cataract blindness in Hungary

摘要

AIM:To estimate the prevalence of blindness and visual impairment resulting from cataract in the population aged≥50 y in Hungary,and to assess the cataract surgical services.METHODS:A rapid assessment of avoidable blindness(RAAB)was conducted.A total of 3523 eligible people were randomly selected and examined.Each participant underwent surgery for cataract was interviewed with regard to the year,place,and costs of the surgery.Participants with obvious cataract were asked why they had not yet undergone surgery(barriers to surgery).RESULTS:An estimated 12514 people were bilaterally blind;the visual acuity(VA)in 19293 people was<6/60,and the VA in 73962 people was<6/18 in the better eye due to cataract.An estimated 77933 eyes are blind;98067 eyes had a VA of<6/60,and an estimated 277493 eyes had a VA of<6/18 due to cataract.Almost all cataract surgeries were conducted in government hospitals.The age-and sexadjusted cataract surgical coverage with VA<3/60 in eyes was 90.0%.The rate of good visual outcome after surgery was 79.5%.Ocular comorbidity was the main cause of poor outcome(78.1%),followed by late complications(such as posterior capsule opacification)(17.2%),inadequate optical correction(3.1%),and surgical complications(1.6%).The main barrier to surgery in people with bilateral cataract and VA of<6/60 was‘need not felt’.CONCLUSION:The prevalence of visual impairment resulting from cataract is slightly higher than expected.The quality of the cataract surgical service seems adequate in Hungary.However,the number of cataract operations per year should continue to increase due to the increasing patient demands and the aging population.
