Diagnostic Tests

Digital Pupilometry

Accurate pupil size measurement is essential for patients considering laser refractive surgery, and yet, most measuring techniques are subjective in nature. A notable exception is the Procyon Digital Pupillometer, which digitally scans and records the pupil in dim, medium, and bright light, taking the guesswork out of pupil measurement. Commonwealth Eye Surgery is the first practice in Kentucky to utilize this technology, which clarifies your surgical options and maximizes your safety and results.

External Photography

External photography allows us to document and observe changes in the superficial structures of the eye and eyelids. The camera is mounted to a slit lamp and has a monitor that allows us to show the patient and family the objects of interest, thus improving patient comprehension and alleviating anxiety.

Fluorescein Angiography

Fluorescein dye can be injected in a forearm vein, and used to map the blood vessels in your retina through use of a sensitive, high speed camera. This test identifies areas at risk for bleeding and vision loss in patients with diabetes or macular degeneration.

Gonioscopy

Gonioscopy is an examination used to evaluate the drainage system of the eye, or the trabecular meshwork, and its anatomical relation to the adjacent iris. A special contact lens mirror is used to visualize these structures, which are hidden from direct observation. Gonioscopy is a painless examination used to determine whether the area where fluid drains out of your eye, or drainage angle, is either open or closed. Depending on your age and whether you are at high risk for developing glaucoma, gonioscopy may be a routine part of your evaluation.

IOL Master

This apparatus measures both the length of the eye and the corneal curvature and calculates the required implant power of each eye. Accuracy in IOL power selection optimizes your vision after cataract surgery and helps reduce dependence upon glasses. The IOL Master uses an infrared laser to measure axial length to the hundredth of a millimeter, the most accurate technology available today.

OCT

OCT uses infrared light to obtain a detailed and precise image of the retina and optic nerve. Analogous to a CT scan, the OCT allows detection of microscopic changes before they become visible to an examiner’s eye. This technology aids in the diagnosis of retinal diseases, as well as determining whether glaucoma is adequately controlled.

Orbscan (Pachymetry)

An Orbscan is a diagnostic test that measures the curvature and thickness of your cornea (the clear window of your eye). This “no touch” procedure quickly completes 10,000 measurements and determines subtle irregularities in the shape of your cornea that cannot be determined by standard examination techniques. The Orbscan is critical in determining your suitability for laser refractive surgery

Retinal Photography

A special camera mounted on a microscope digitally records images of the retina, the retinal blood vessels, and the optic nerve. This allows your doctors to follow and treat glaucoma, diabetic retinopathy, and macular degeneration with great accuracy.

Specular Microscopy

Specular Microscopy measures the number, shape, and size of the cells on the inside surface of your cornea. These cells maintain corneal clarity and good vision. Trauma and some inherited conditions may cause a loss of these cells and an accurate assessment of their health is crucial in planning your cataract surgery.

Visual Fields

The Haag-Streit Octopus Field Analyzer measures hundreds of spots in your side (peripheral) vision within 4 minutes, detecting and monitoring glaucoma, strokes and tumors. This “smart test” also determines your ability to provide consistent responses, filtering out misleading data.
