Visual Performance of the Presbyopic Patient with Multifocal Contact Lenses

Abstract

Relevance: This literature review highlights the importance of visual performance in presbyopic patients using multifocal Contact Lenses.
Summary: A literature review of publications from recent years was conducted, focusing on the visual performance of presbyopic patients using multifocal contact lenses, summarizing studies that meet predefined inclusion criteria. Bibliographic search was performed using descriptors and Boolean operators, and these results were screened based on inclusion and exclusion criteria to obtain final outcomes. Searches were conducted using descriptors, ensuring they appeared in the title or abstract of the article. To refine the search on the PubMed platform, additional filters, such as inclusion and exclusion criteria, were applied. A total of 78 results were obtained initially. After applying inclusion and exclusion criteria, the number of articles was reduced to 15 results.
Multifocal Contact Lenses (CLs) are a good optical correction alternative for presbyopia, as evidence confirms that Visual Acuity (VA) is good and there are no differences in VA compared to progressive glasses. Contrast Sensitivity (CS) is also not affected when using multifocal CLs, and from defocus curves, it can be inferred that the patient has a good focused space for everyday tasks. However, we must consider additions, as higher additions result in lower VA and CS values. Therefore, the higher the addition of our patient, the lower the VA and CS. Compared to monovision, multifocal CLs provided better visual performance without the reduction in stereopsis produced by monovision technique.
