Lipiflow is a heat treatment for Meibomian Gland Dysfunction. You may have heard that clogged oil glands are part of the problem for dry eyes. Lipiflow helps to remove these blockages in a warm, soothing way.

Our tears contain three layers — oil (lipid) layer, water (aqueous) layer and a mucin layer. These three layers are responsible for keeping the eye surface lubricated.

With meibomian gland dysfunction, the glands become clogged, causing insufficient oil production for the tear film. The amount of oil or its quality decrease when there is a dysfunction in the glands. MGD causes tears to evaporate too quickly, resulting in dry eyes.


A Diopsys® ERG vision test is a painless, safe, non-invasive way to objectively measure the function of your retina.

When light enters your eye, it is turned into electrical energy by cells in the retina. Pattern ERG, or electroretinography, uses visual stimuli from a computer screen in different patterns and contrasts to elicit that electrical response. The electrical energy created is measured by the Diopsys® ERG vision test, and used to create a report for your doctor. It is similar to an EKG, but for your eyes.

What To Expect During A Comprehensive Eye Exam

Salem Eye Professionals uses the most up-to-date methods and equipment to healthfully evaluate your vision and eyes.

Visual Acuity Test

Among the first tests performed in a comprehensive eye exam are visual acuity tests to measure the sharpness of your vision.

Color Blindness Test

In addition to testing for hereditary color vision deficiencies, color blind tests can also detect possible eye health problems that may affect your color vision.

Cover Test

The cover test checks how well your eyes work together to focus on an object. It is used to detect strabismus or a more subtle binocular vision problem that could cause eye strain or amblyopia (lazy eye).

Ocular Motility Test

Ocular motility testing determines how well your eyes follow a moving object and quickly move between and accurately fixate on two separate targets. Problems with eye movements can cause eye strain and affect reading ability, sports vision, and other skills.

Stereopsis (Depth Perception) Test

Stereopsis is the term used to describe eye teaming that enables normal depth perception and appreciation of the 3-dimensional nature of objects.


Your eye doctor may perform this test early in the eye exam to obtain an approximation of your eyeglass prescription.

The lights are dimmed in the room while you are asked to focus on a target as the doctor shines a light into your eye. The doctor flips lenses on a machine in front of your eyes. This test estimates which lens powers will best correct your distance vision.

Based on the way the light reflects from your eye, the doctor can estimate your prescription and serve as a good starting point for the refraction test.

This test is especially useful for children and patients who cannot answer the doctor's questions accurately.

Visual Field Test

This test is used to check for blind spots, called scotomas, in your peripheral or "side" vision. These types of blind spots can originate from eye diseases such as glaucoma.


This test uses a phoropter to determine your exact eyeglass prescription for eyeglasses and contact lenses.

The refraction determines your level of hyperopia (farsightedness), myopia (nearsightedness), astigmatism and presbyopia.


Autorefractors are especially helpful for determining an eyeglass prescription for young children and other patients who may have trouble sitting still, paying attention, and providing the feedback needed to perform accurate manual refraction.

Slit Lamp Exam

A slit lamp is a binocular microscope used to examine the structures of your eye under high magnification to examine the structures of the front of your eyes, including your eyelids, cornea, conjunctiva, iris, lens, retina, and optic nerve.

A wide range of eye conditions and diseases can be detected with the slit lamp exam, including cataracts, macular degeneration, corneal ulcers, and diabetic retinopathy.

Glaucoma Test

tonometer measures the pressure in your eyes to help determine if you have glaucoma.

The common "puff-of-air" test is technically known as non-contact tonometry, or NCT. It is completely painless, and the tonometer does not touch your eye.

There are no warning signs of glaucoma until you already have significant vision loss. For this reason, routine eye exams that include tonometry are essential to rule out early signs of glaucoma and protect your eyesight.

Pupil Dilation

Pupils are dilated to better view the eye's internal structures. Pupil dilation is very important for people with risk factors for eye disease because it allows for the most thorough evaluation of the health of the inside of your eyes.

Additional Examination

A more thorough ocular medical examination may be recommended based on what the doctor finds. These procedures are typically billed to your medical insurance.
