Everyone should include a thorough eye examination as part of your routine
health care. Many eye diseases can exist for several years with no
indications. Other diseases, such as diabetes and high blood pressure
can be detected during a routine eye exam prior to realizing any physical
- First the doctor will ask you about your medical history and any
vision problems you may be experiencing.
- Then the doctor will check the exterior part of the eyes to
determine the health of this area of the eye.
- And finally the doctor will determine your visual acuity. During this
step it will be determined if corrective glasses or contacts will
improve your vision, and if any signs of disease are present.
While assessing your visual acuity and checking for the presence of any
diseases, the following tests may be performed but will not be limited to
- Cover Test
- Slit lamp examination
- Glaucoma Test
This is one of the first checks the doctor will make; it will allow the doctor to
perform an objective measurement to obtain an approximate prescription.
This will lay the ground work for a thorough and accurate refraction.
A refraction assessment will help the doctor determine a corrective lens
prescription that will provide the best possible clarity of vision. This may be
for glasses or contacts. Normally the doctor will use a piece of diagnostic
equipment call a phoropter.
During a cover test you will focus on a small object and the doctor will cover
each of your eyes alternately while you fix your focus on the target point. As
you do this, the doctor will observe how much each eye moves when
uncovered before picking up the target point. This test is performed for both
distance and near.
Slit lamp examination
The slit lamp is an instrument that the doctor uses to examine the health of
your eyes. The slit lamp, also called a biomicroscope, allows the doctor to
get a magnified image of the structures of the eye in order to thoroughly
evaluate them for signs of infection or disease.
Tonometry measures your intraocular pressure — the pressure inside your
eyes. It helps your eye doctor detect glaucoma, a disease that causes
pressure to build up inside your eyes and can cause blindness. Glaucoma
can be treated if it’s caught early.
An associated effect is elevation of the intraocular pressure, which leads to
damage of the optic nerve and subsequent peripheral vision loss. Most
people will experience no initial symptoms of open-angle glaucoma, but
will eventually develop peripheral vision loss, headaches, blurred vision,
difficulty adapting to darkness and halos around lights. Closed-angle
glaucoma may have additional symptoms such as pain in the eye, a pupil
that is non-responsive to light, possible redness, nausea and a bulging
The pupil is considered the window of your eyes and by dilating your pupils
it allows the doctor to better view the eye's internal structure.
The examination of the interior eye is accomplished by illuminating the
inside while utilizing different instruments to inspect the internal structure.
Dilating drops take approximately 10 to 20 minutes to start working. While
your pupils are dilated they will allow more light to enter the eye, this in turn
will make your eyes light sensitive for several hours, and may also affect
your ability to focus on objects up close. This can last for up to several
hours depending on the strength of the drops used.

Comprehensive eye examination
Dr. Winnie Lei,O.D. and staff want to make sure that your contact lens
wearing experience is safe and comfortable. Our goal is to protect your
vision for a lifetime.
Prior to having a contact lens Fitting (sometimes call a contact lens
evaluation), you will need to have a current eye exam. This will include a
thorough eye examination for the health of your eyes and a refraction to
determine your eyeglass prescription. After these two stages are
complete, then the doctor can perform a contact lens evaluation.
The Contact Lens Evaluation includes:
- Measurement of the cornea.
- Assessment of how the contact lens affects the cornea,
conjunctiva, tears film and eyelids.
- Evaluation of the contact lens on your eyes for optimal fit and
- Information about contact lens care, safety and solutions.
- Contact Lens Prescription.
Contact lens fitting/evaluation
Before surgery a thorough baseline evaluation and eye exam will be
performed to determine if you are indeed a candidate for lasik surgery.
After the vision test, we will discuss the benefits and risks of lasik surgery
and answer any questions. We want you to know what you can expect
before and after lasik eye surgery.
We will still be your eye care provider. Even if you don’t need eyeglasses
or contact lens any longer, you still need annual eye health examinations.
Remember, our focus is taking care of all your vision needs for a lifetime.
Let us help you sift through all the lasik information available so you cam
make an informed decision about your precious eyesight.
Co-manage Pre and Post LASIK procedures
The doctor may want to check for the possible presence of blind spots
(scotomas) in your vision by performing a visual field test. Blind spots can
originate from glaucoma, strokes as well as other diseases. Sometimes
referred to as a “side vision” test, a visual field test will assess any loss of
peripheral vision. Analysis of blind spots also may help identify specific
areas of brain damage caused by a stroke or tumor. Some eye and brain
disorders can cause the loss of vision in different areas.

Digital Fundus Photography
Our primary role is to look after the health of your eyes. To aid us in that
endeavor we have acquired a state of the art high definition digital fundus
camera, also referred to as a retinal camera.
With the fundus camera we can examine the eye in much more detail
without having to shine a bright light in your eye for as long as we did
previously. When performed in conjunction with your routine eye
examination we can observe and monitor the smallest changes much
earlier than with a conventional method of examination.
It is designed to take a photograph of the interior and/or anterior surface
of the eye, including the retina, (light-sensitive tissue lining the inner
surface of the eye), optic disc (the point at which the blood vessels enter
the eye and optic nerve is attached), and macula (which is your central
vision, a concern here is the degeneration of the macula). The fundus
camera is used by eye doctors to screen, diagnose and monitor the
progression of eye diseases. It also helps as an early indicator for other
health problems including diabetes, melanoma and hypertension.
The photographs are quick and painless, involving a brief flash of bright
light. Within a few seconds the image is displayed on a screen in the
examination room and you will have a chance to see the back of your eye
and discuss the picture with the optometrist.
