A Review of Pharmacological Presbyopia Treatment.

Presbyopia reduces an individual's ability to perform visual tasks at near distances. It is a global problem, affecting over a billion people worldwide. Contact lenses, glasses, refractive surgery, and intraocular lens surgery are the main modalities in presbyopia treatment, although they all have some disadvantages. Thus, there is an increasing need for effective, easy-to-use, and noninvasive approaches for treating presbyopia while not limiting patients' daily activities. Pharmacological presbyopia treatment as an alternative method has been under investigation in recent years. We reviewed all relevant articles using the keywords "presbyopia," "presbyopia treatment," "pharmacological presbyopia treatment," and "presbyopic corrections" from 2010 to February 9, 2020, and summarized the main results of clinical trials, investigating the drops used for presbyopia treatment.
