Optical Coherence Tomography/OCT test for cataract surgery

The OCT is an imaging technique which forms an essential part of the ophthalmic assessment in the 21st century. It uses light waves to capture micro-resolution images of biological tissue such as the cornea, retina and optic nerve. This allows the ophthalmologist to map and measure individual layers of cells and visualize any pathology. 

It is a quick and non-invasive test which does not cause any pain or discomfort. You will be asked to rest your chin on a support and focus your eyes on a point of light inside the machine. The OCT then scans the eye without touching it, and the results are available in less than 5 minutes. 

It is especially useful for the diagnosis of conditions such as Diabetic Eye Disease, Macular Degeneration and Glaucoma. It is also routinely used in the assessment of a patient with cataracts in order to screen for any conditions which may adversely affect the outcomes of surgery.
