Collom & Carney Eye Institute






Collom & Carney Eye Institute performs routine ophthalmic eye evaluations that screen and treat a wide range of opthalmic conditions including cataracts, dry eye syndrome, glaucoma, diabetic retinopathy, and macular degeneration.  Some vision problems are symptomless and pain-free, making it hard to know whether or not you have a problem.  The most effective method for detecting vision problems is through having a routine eye exam performed by an ophthalmic eye doctor.

Tens of millions of Americans are too busy to realize they have uncorrected vision problems, that can very likely lead to worsening eyesight.

Vision problems affect more than 86 million adults over the age of 40.  In children, amblyopia, if not detected early, can have long-term consequences.  Other eye diseases, such as glaucoma can cause irreversible vision loss.  The best way to ensure that your family's vision is healthy is to make sure every member of your family has a regular comprehensive eye exam.

Our doctors use a wide variety of test to examine the eyes.  These tests range from simple ones, like having to read an eye chart, to complex test, such as using a high-powered lens to visualize the tiny structures inside the eye.

Important Information
In order to provide the best evaluation possible it is often necessary to review old medical records.  Please bring along any records of previous eye surgeries, a list of any medications, along with any eye drops you may be currently taking.

Almost all patients will have their pupils dilated.  This is a necessity for the ophthalmic evaluation.  If you are concerned about driving with your eyes dilated, please bring someone to assist you.  Vision may be blurred for hours after the examination.

Please check in at the reception area.  If you are a new patient, please plan to arrive at least 15 minutes before your appointment time.

    A Comprehensive Eye Exam

Regardless of the type of test being performed, it is important that you follow directions closely and be honest in your answers.  This will ensure accurate results and the most thorough evaluation of your eyes.  Here are the basic tests that you will likely encounter during a routine eye exam: 

History - A complete history will be taken.  For example, any current eye problems, all prescription medicines, as well as any past eye surgeries will need to be noted.  This all very helpful information in order to best meet your needs.
Visual Acuity - The patient will be asked to cover one eye and look at a standard eye chart, then read the line of letters and/or numbers that are clearest.  If the doctor tells your that you have 20/20 vision, for instance,  this just means that you can clearly see a certain letter on the standard eye chart equivalent to what you would see at 20 feet.  Although very important, there is so much more to healthly vision than 20/20.      
Retinoscopy - In retinoscopy, the room lights will be dimmed and you will be given a large target (usually the big "E" on the chart) to fixate on.  As you stare at the "E", the eye doctor will shine a light at your eye and flip lenses in a machine in front of your eyes.  Based on the way the light reflects from your eye, the doctor is able to "ballpark" your prescription.  This test is especially useful for children and non-verbal patients who are unable to accurately answer the doctor's questions.

                                                                                             Refraction - This is the test that the eye doctor uses to determine your exact prescription.  The doctor will put an instrument called a phoropter in front of your eyes and show you a series of lens choices.  He or she will then ask you which of the two lenses in each choice looks clearer.  The doctor will continue to fine-tune your power until there is a final prescription that is then used in your eye glasses and contacts (if needed).
Glaucoma Testing - The purpose of glaucoma test is to measure the intraocular pressure (pressure inside of the eye).  The doctor will start by putting a numbing drop in the eye combined with a yellow dye.  Then the patient will be asked to put their chin in the machines chin rest.  The doctor will have the patient stare straight ahead while he or she comes close to the front of each eye.  Based on the eye's resistance to the applanation tonometer, the machine calculates the intraocular pressure inside of the eye, these are important tests for ensuring the long-term health of the eyes.
Dilation - Dilating drops are used inside of the eye in order to make the pupils bigger.  This is also a very essential part of the eye examination.  Think of the pupil as a window to the inside of the eye, dilation opens the window wider allowing the doctor to see the internal structure of the eye.  Dilating drops usually take about 20-30 minutes to start working.  Dilation will last serveral hours, making your vision blurry and your eyes sinsitive to light.  Sunglasses are recommended, and we will supply you with a disposable pair of tinted shades.
These are the most common test performed during a standard eye examination.  Other evaluations may require additional, more specialized tests.
