A detailed case history of a patient's vision problem is most
helpful in determining the cause of the problem.
That is why we
ask you so many questions on the initial history questionnaire when
you come to our office. In addition, modern technology has
provided us with many excellent tools to solve problems. We
strive to stay current and have state of the art diagnostic equipment.
This instrument requires the pupil to be dilated but affords a
wider stereoscopic view of the interior of the eye. The doctor
uses a combination of a head mounted light source and a hand held
condensing lens to view the interior of the eye.
At Burrows Vision Clinic we have a new instrument, OPTOS
Retinal Imager, that can eliminate the need for most dilations.
The Biomicroscope is commonly referred to as a slit lamp.
This enables the front portion of your eye to be seen in different
amounts of magnification. This is invaluable in doing corneal
health evaluations, removing foreign bodies, observing contact lenses
on the eye and follow up on eye infections. It can also be used
to view internal structures of the eye with a dilated pupil.
Dicon 4000
|
This is a computerized method to plot a person's visual field.
The patient responds to various tiny flashes of light of varying
intensity and the area of the visual field is plotted. This
tests the integrity of the optic nerve and possible changes due to
glaucoma, tumors, and retinal problems. |
Direct Ophthalmoscope
|
| |
This is a hand held device used to view the internal structure of
the eye. |
Keratron Topographer
|
This measures the topography (corneal shape) of the cornea.
It is very useful in contact lens fitting and in evaluating eyes for
LASIK, both pre and post-op. |
Optos Retinal Imager
|
 This is our newest diagnostic instrument. As of November,
2003 our office was the 3rd in the state of Nebraska to have an OPTOS
Retinal Imager.
This fantastic instrument enables us to obtain a retinal image of
the entire retina in 1/4 of a second. The advantage of the
Optomap image is that we can see the entire retina without dilating
the pupil. This is much more patient friendly in that the blurry
vision after dilation is eliminated. We also have a permanent
record of the retinal image to compare to future images. This is
invaluable in monitoring eye health.
The Optomap images are taken by technicians and analyzed by the
doctor who will take the time to go over the results with you.
More information on this instrument can be found on the
OPTOS website.

Phoropter
|
This is the instrument that you look through that the doctors use
to determine refractive error. It contains banks of lenses that
the doctor changes according to your responses during the vision test.
In this way, the doctor can determine the corrective lenses needed for
your distance and near vision.
|
Tonometer
|
| |
The Tonometer is used to measure IOP (Intra Ocular Pressure).
All eyes have pressure - this gives the eyeball rigidity and it should
remain in the normal range. If pressure is elevated it may
indicate glaucoma.
Burrows Vision Clinic utilizes an applanation type instrument which
has proven to be the most accurate method of measurement. This
instrument will not blow air into your eyes. |
Topcon Autokeratometer/Refractor
|
This instrument determines curvature readings of the cornea and
refractive errors. This is one of the initial tests done by
our optometric technician. |
Trial frame and lenses
|
| |
Trial frame and lenses are used to actually simulate your vision
through your new prescription. This enables the doctor to
determine the lens power that gives you the optimum vision possible.
