Surgery of age-related cataract: epidemiological nuances

AIM: To perform the analysis of the age composition of patients with a planned in-patient surgical procedure cataract phacoemulsification. MATERIALS AND METHODS: Three cohorts of patients diagnosed with age-related senile cataract were analyzed for the periods 20002003 (n = 6737), 20072009 (n = 13,015), and 20152017 (n = 1363) on the basis of age at the time of planned surgery in the ophthalmology hospital S.V. Belyaev Kuzbass Clinical Hospital. Persons with a diagnosis of congenital, complicated, traumatic cataract and persons operated as out-patients were excluded from all samples. RESULTS: At the first stage, the average age of patients at the time of surgical treatment of patients diagnosed with senile cataract was calculated. At the second stage, the age of operated patients was analyzed by decades of human life. At the third stage, the assessment of the judgment about the rejuvenation of the age of operated patients with incipient cataract according to professional indications was carried out. CONCLUSIONS: The average age of patients operated on with senile cataract during a fifteen-year period is a stable value in the range of 6668 years. In the dynamics from 2000 to 2017, there was a redistribution of patients with senile cataract within the cohort by age. Rejuvenation of the age composition of persons with cataracts occurred due to an increase in patients aged 5160 years by 2 times and a decrease in patients aged 7180 years by 1.6 times. The proportion of patients undergoing surgical treatment for senile cataract in a hospital setting with visual acuity of 0.1 or less is stable and amounts to 78.487.5 %.
