Intraocular lens ‘iris clip’
Mark Bartley, Cambridge University Hospitals NHS Foundation Trust
This image shows how an ‘iris clip’, also known as an artificial intraocular lens (IOL), is fitted onto the eye. An iris clip is a small, thin lens made from silicone or acrylic material, and has plastic side supports, called haptics, to hold it in place. An iris clip is fixed to the iris through a 3 mm surgical incision, and is used to treat conditions such as myopia (nearsightedness) and cataracts (cloudiness of the lens). This particular patient, a 70-year-old man, regained almost full vision following his surgery.
Photographing the human eye is extremely challenging: photographers have to use techniques to steady the eye’s constant movement. These often include using a chin rest, asking the patient to fixate on a light, or darkening the room to prevent any further distraction. The photography seen here is the result of one method within an area known as anterior segment imaging, which concentrates on the structures within the front third of the eye.
