The Zeiss OCT provides Dr. Kelly a non-invasive way to scan the retinal nerve fiber layer (located in the back of the eye) to screen and monitor macular and optic nerve issues. The OCT uses light waves to produce a cross-sectional image of the retina and optic nerve. Pre-operative OCTs of the macula are frequently performed to determine if underlying structural issues (not easily identifiable due to a denser cataract) are present. Dr. Kelly counsels patients and seeks referrals to specialists for patients in which a macular or optic nerve issue may significantly affect vision after cataract surgery.
