Auto-Refractor – Keratometer
We use a very accurate Canon Auto-Refractor – Keratometer in the assessment of vision, contact lens fitting and various diseases of the cornea and inner eye structures.
Dicon Dynamic Auto-Perimeter
We use a Dynamic Auto-Perimeter, rather than the more common, older, static perimeters. Dynamic perimeters allow for a more interesting and accurate visual field assessment in screening. This is essential for following common eye disorders, such as glaucoma, and detecting a variety of injury and disease related problems with vision. Every year we detect unexpected eye and visual system related problems, such as optic neuritis, brain tumors and cerebral spinal fluid hypertension.
Binocular Indirect Ophthalmoscope
Whether it is evaluating flashes and floaters or looking at retinal holes and diabetes, a good wide field view of the back of the eye is essential. The binocular indirect ophthalmoscope is the idea instrument for getting these views. We use it both to view acute problems, such as retinal detachments and bleeds, and for long-term changes, such as evaluating congenital retinal disorders and monitoring laser treatment of diabetic retinopathy or macular degeneration.
We use a Canon corneal topographer to map the cornea when needed. Corneal topography can be useful for helping with difficult contact lens fits and for detecting and monitoring corneal diseased, such as keratoconus or corneal peripheral degenerations.
Goldman Applanation Tonometry
Tonometry is a measurement of the pressure inside the eye. Eye pressure is related to a number of diseases particularly various forms of glaucoma. Goldman applanation tonometry is the method that we use and it is considered the most accurate and reliable technique for measuring eye pressure. This is the method used by almost all glaucoma researchers and by glaucoma specialists. Many of our patients also say that they find it much easier and more comfortable than air puff tonometry, which is a common alternative method.
Binocular & Stereo Vision Testing
Much of our vision is determined by how the eyes work together and not just how each eye sees by itself. Many developmental and adult vision problems relate to problems with binocular vision and stereo (also known as 3-D) vision.
Accurate measurement of your new prescriptions or previous glasses is made with an auto-lensometer. It can also measure additional lens characteristics such as prism.
