EPIC-5100 Vision Diagnostic System

How many times have you gone for an eye exam and been asked "Which is better, one or two?" Our EPIC-5100 Vision Diagnostic System allows us to minimize the number of times you have to be asked these questions during your eye examination.

The Epic-5100 is an automated refracting unit interfaced with our electronic medical record recording system. This instrument gives us the opportunity to measure your refractive error more accurately without the fatigue you may notice with traditional eye exams. Lens power changes can be assessed to 1/8 of a diopter, and power locations can be rotated in as little as 1 degree increments to achieve accurate results for your prescription for nearsightedness, farsightedness, or astigmatism. And while we may still have our optometrist refract you, the EPIC system gives him a better starting place which shortens your visit time.

Come in and compare your experience from past eye exams and notice the significant difference in ease and quality of the EPIC-5100 Vision Diagnostic System.

Ultrasound or A-Scan

Ultrasound technology has been around for many years. What sets our system apart from other similar equipment is how it functions and how we use the information it provides.Prior to having an IOL or an ICL implanted in your eye it is necessary to know the precise width of the lens we are going to use. The technology employed by our A-Scan unit provides a visualization of the lens and the surrounding area in high resolution. This in turn allows us to make the proper measurement so that the lens we use fits and thus gives us the result we are looking for.

What is OCT?

At Woodhams Eye Clinic, we are committed to always placing the patient's best interest first. That is why we invest in the latest diagnostic technology. Our newest investment is Optical Coherence Tomography (OCT). OCT is a relatively new diagnostic modality that provides high-resolution, cross-sectional imaging of the back of the eye. It is capable of detecting changes in the back of the eye that may affect the outcome of your surgery.

Thus, we can look for the early stages of diseases like glaucoma, diabetic retinopathy and macula edema, all of which have the potential to change your sight. The test is as simple as taking a picture.

OCT is just a part of our technology investment into your vision improvement.

Custom Vue

The STAR S4 IR™ laser incorporates advanced technologies into the Advanced CustomVue treatment, delivering the highest level of precision and accuracy ever achieved. Surgeons rate the Advanced CustomVue procedure as the most effective advanced laser treatment available today,* and it is FDA approved to treat the broadest range of indications; including hyperopia, all forms of astigmatism, and myopia up to 11 diopters of correction. Results of the clinical trials for all indications showed that one year later: More than 95 percent could pass a driving test without glasses or contact lenses. Plus, almost three quarters could see 20/20 or better without glasses or contact lenses.

The vast majority were satisfied or very satisfied with their night vision after treatment compared to night vision before treatment with glasses or contact lenses.


Understanding the shape and thickness of the cornea is important to any refractive procedure. The Pentacam is a diagnostic test that analyzes and measures the cornea, the clear front surface of the eye where light rays enter. When considering laser vision correction or cataract surgery, this advanced diagnostic instrument is a real advantage over all other ocular diagnostic equipment available today.

The Pentacam HR uses a specialized camera which provides sharp, crisp images of the ocular structures from the front (anterior) surface of the cornea to the back (posterior) crystalline lens capsule. In less than 2 seconds, 100 scans of the eye produce an accurate 3-dimensional mathematical model of the front of the eye.

These results provide our doctors precise measurements of the central cornea, illustrations of the individual corneal layers, and imaging of intraocular lens implants in lens replacement surgery. The Pentacam has enabled our doctors to analyze the eye with an accuracy that was previously not available. You can have the confidence that the most accurate clinical data is being collected for your refractive surgery procedure.

If you are nearsighted, but not an ideal LASIK candidate

Many phakic IOLs require precise implantation to provide superior vision with minimal risk to complications. To optimize placement of the ICL, a 3-dimensional anterior chamber volume map is generated to determine the amount of intraocular space available to position the lens implant. After your surgical procedure, the distance of your lens implant is objectively measured to the nearest 1/1000 of a millimeter to ensure proper lens positioning.

If you need cataract surgery…

When the crystalline lens increases in density, it causes an excessive scattering of light and blurred vision. This is known as a cataract. Using lens desitometry readings, the Pentacam HR can measure the density of the crystalline lens and objectively measure the amount of its cataractous change. With increasing age, it will be necessary to undergo cataract surgery to maintain functional vision.

If you have had previous refractive surgery, such as radial keratotomy (RK) or LASIK, the Pentacam HR utilizes a special software program to precisely calculate the power of an intraocular lens implant used for cataract surgery. "Equivalent K-readings" determined by the Pentacam HR are implanted into the IOL calculation formulas to accurately determine the correct IOL needed for all patients, even those with abnormal corneas. Instead of using assumptions or approximations, the Holladay Report enables patients who have undergone previous corneal surgery feel assured that their previous eye surgical procedures will not interfere with the outcome of additional necessary surgery.

OQAS (Optical Quality Analysis System)

Are you unhappy with your vision despite being told that you have "20/20" vision by your eye care practitioner? Do you notice more difficulty seeing during the night as compared to the day?

Naturally, the eye has inherent distortions that affect the quality of your vision. These distortions, also known as higher order aberrations, have a significant impact on the sharpness and detail of the image viewed. Additionally, as the eye ages, light that enters the visual system becomes more scattered due to evolution of cataracts. This contributes to the troublesome halos and starbursts many people notice in low lighting environments.

OQAS provides an objective measurement of the optical quality of the eye. A punctual light source is imaged on your retina, and the size and shape of this light spot is analyzed as it passes through the various ocular structures by the OQAS. Both 2- and 3-dimenstional maps of the retinal image are generated to qualitatively and quantitatively evaluate the performance of your visual system. Now, objective measurements of "true vision quality" are available to effectively monitor the results of your LASIK or cataract surgery.
