This is the next generation in refractive diagnostics: an objective method of measuring the entire optical system. A Hartmann-Shack sensor containing thousands of tiny lenslets captures the displaced light rays as they exit the pupil. When calculated against the mathematical ideal, this produces the most exact measurement of refractive error and higher order aberration (HOA’s) obtainable today, assisting our doctors in achieving superior refractive accuracy.
VISX iris registration technology also helps produce more precise results by measuring the position and size of the iris while the patient is sitting and lying down, which allows for the most accurate delivery of each patient’s individual laser treatment.
The Orbscan IIz is a multidimensional corneal topography diagnostic system that provides a complete analysis of the eye’s corneal optical system by utilizing slit scanning technology. The optical acquisition head scans the eye using light slits that are projected, providing 9000 data points. The result is a very accurate picture of the cornea that is used to rule out underlying problems such as very thin corneas and keratoconus, which may contraindicate elective refractive LASIK surgery. The Orbscan IIz can also be used to measure corneal thickness and map the cornea for a more accurate contact lens fitting assessment.
Because every person’s eyes are unique, like fingerprints, it can be difficult to determine the appropriate specifications of the IOL to be implanted during cataract surgery. The Zeiss IOL Master® now provides physicians with information on key ocular measurements such as axial length, corneal curvature and anterior chamber depth, making it possible to choose the right IOL for each patient. Approved by the FDA in 2000, the non-contact IOL Master is the only product in the world that makes these “optical biometry” examinations possible and has proven to be five times more accurate than traditional IOL-fitting technologies.
Optical coherence tomography (OCT) is an advanced technology used to produce cross-sectional images of the retina, the light-sensitive lining on the back of the eye where light rays focus to produce vision. These images can help with the detection and treatment of serious eye conditions such as macular holes, macular puckers, and retinal swelling from diabetic retinopathy or macular degeneration. Imaging can be also be performed on the optic nerve to address progression of glaucoma as well as the front of the eye (cornea and anterior chamber) to evaluate various disease states.
OCT uses technology that is similar to CAT scans of internal organs, using a scattering of light to rapidly scan the eye to create an accurate cross-section. Unlike other imaging techniques, OCT uses light to produce high resolution images, rather than radiation, sound, or radiofrequency waves. As a result, there is no risk to the patient or harmful side effects.
Optos Panoramic Retinal Imaging System
The optomap retinal exam produces the most comprehensive image of the retina without pupil dilation. This allows us to perform a more thorough and comfortable exam than was previously possible. The result is that we can detect retinal problems including macular degeneration, glaucoma, retinal holes or detachments, and systemic diseases such as diabetes, stroke, and high blood pressure. Experience with this technology has already led to improved disease detection and has possibly prevented vision loss and blindness in several patients.
This state-of-the-art parameter provides fast, accurate results by combining the accuracy of Goldmann standard stimuli with sophisticated computer technology. Screening and threshold tests include glaucoma, retinal, neurological, macular retina and advanced glaucoma capabilities.
Dry, scratchy, irritated eyes? The problem may not be your eyes, but rather your eyelids. OCuSOFT® Lid Scrub® effectively removes excess oil and debris from the eyelids that may lead to eye irritation including blepharitis or dry eyes. Consult your eye care physician to see which OCuSOFT® product is right for you.
Selective Laser Trabeculoplasty (SLT) is an advanced laser system that improves the flow of fluid in the eye, lowering eye pressure for patients with glaucoma.
Using a focused, narrow wavelength, SLT targets specific cells of the eye — those containing melanin, a natural pigment — leaving surrounding cells intact. The procedure is painless and has no side effects, although patients are given anti-inflammatory eye drops before and after treatment. Eye pressure may drop as quickly as a day after the procedure.
According to the latest studies in ocular hypertension, doctors have determined that corneal thickness plays a significant role in its evaluation. It is now suggested that patients who are glaucoma suspects have pachymetry done to help in determining whether treatment should commence.
We provide the technology necessary to gain an unobstructed view of the retina, significant in determining the presence of detachments, hemorrhages, and tumors. Ultrasound evaluation has always been an integral step in the evaluation of a patient’s pre-surgical fitness at the center.
Fluorescein angiography is a diagnostic test which uses a special camera to photograph the structures in the back of the eye. Fluorescein angiography is used to visualize the circulation of the retina and is very useful for finding leakage or damage to the blood vessels which nourish the retina. During this test, a colored dye is injected into a vein in the arm of the patient. The dye travels through the circulatory system and reaches the vessels in the retina and those of a deeper tissue layer called the choroid. This is captured on camera. Fluorescein angiography is considered very safe and serious side effects from this test are extremely rare.
Lasers are most commonly used in Ophthalmology in the treatment of diabetic retinopathy, age-related macular degeneration, glaucoma and cataract. Depending on the procedure being performed, different types of lasers may be used. These include Excimer, Argon, Diode and Neodymium. These different laser types operate on different wavelengths and have different tissue effects.
The Specular Microscope EM-3000 provides corneal endothelium imaging by using the specular optical principle with a visible light source, lenses and a CCD camera. These project a slit of light to the cornea from an oblique direction and capture the reflected image of the corneal endothelium by CCD camera. The EM-3000 newly incorporates an LED light source in place of a halogen lamp and a high-speed CCD camera to capture 15 images in series. It automatically selects and instantly displays the finest image of these images. In addition, a built-in clinical application delineates the endothelial cells automatically and displays statistical data such as cell numbers, average area and cell density on the color LCD.
