Ocular surface homeostasis and cataract surgery
Abstract
Cataract surgery is the most common ophthalmological procedure worldwide. It is particularly frequent in the elderly, due to the changes undergone by the tear film in advanced ages. On many occasions and due to ocular surface homeostatic alterations, patients continue to experience great discomfort after the operation, such as lacrimation or a foreign body sensation, which makes them doubt the satisfactory outcome of the surgery. A review was conducted about the topic to understand the reasons for these symptoms, their causes and the preoperative tests required to achieve a better postoperative evolution. Use was made of the platform Infomed, specifically the Virtual Health Library.
Key words: Cataract surgery; lacrimation; dry eye syndrome; ocular surface; homeostasis.
