The investigators study aims to capture the objective effects of pterygium surgery on tear layer lipid thickness and the tear layer.
Previous objective studies of the tear film has been limited to corneal staining grading, tear break up time and Schirmer's test which have been shown to poor to moderate repeatability. The effect of pterygiums on tear layer lipid thickness (LLT) has not previously been explored. With the LipiView Ocular Surface Interferometer, the investigators have the ability to assess the optical coherence interference pattern produced by light reflected off the tear film in a safe and non-invasive manner. Software analysis of the image then measures the tear LLT which can be used to objectively quantify the diagnosis of lipid-deficient dry eye.
