The World Health Organization recommends monitoring the trends and assessing the progress of ophthalmic care focused on the actual needs of people. To solve these problems, the authors of this paper have proposed and tested an analytical model, named «Cataract», which on the one hand can help evaluate the needs of the population in terms of cataract treatment, and on the other — assist with analysis of the available resources to meet these needs. The model can help identify the bottlenecks and predict the required resources, as well as assess the degree of satisfaction of the population’s needs with the current and projected amount of medical care. This model allows analyzing, planning or predicting the resources of healthcare facilities needed for the treatment of cataracts while simultaneously assessing its impact in order to meet the medical needs of patients with cataracts.
