Economic Evaluation of Cataract: A Systematic Mapping Review

Description

Introduction: The purpose of this article was to ascertain the existing literature and find the gaps in economic evaluations of cataracts. Methods: Systematic methods were used to search and collect the published literature on economic evaluations of cataracts. A mapping review of studies published in the following bibliographical databases was performed: the National Library of Medicine (PubMed), EMBASE, Web of Science (WOS), and the Central of Reviews and Dissemination (CRD) database. A descriptive analysis was conducted and relevant studies were classified into different groups. Results: Among 984 studies screened, 56 studies were included in the mapping review. Four research questions were answered. There has been a progressive increase of publications during the last decade. The majority of the included studies werepublished byauthors frominstitutionsinthe USA and UK. The most commonly investigated area was cataract surgery followed by intraocular lenses (IOLs). The studies were classified into dif ferent categories according to the main outcome evaluated, such as comparisons between different surgical techniques, costs of the cataract surgery, second eye cataract surgery costs, quality of life gainaftercataractsurgery, waitingtimeofcataract surgery and costs, and cataract evaluation, follow-up, and costs. In the IOL classification, the most frequently studied area was the comparison between monofocal and multifocal IOLs, fol lowed by the comparison between toric and monofocal IOLs. Conclusions: Cataract surgery is a cost-effective procedure compared with other non-oph thalmic and ophthalmic interventions and sur gery waiting time is an important factor to consider because vision loss has a huge and broad-ranging impact on society. Numerous gaps and inconsistencies are found among the studies included. For this reason, there is a need for further studies according to the classification described in the mapping review.
