A comprehensive eye exam includes the assessment of vision and ocular health. A refraction determines if one is myopic (nearsighted), hyperopic (farsighted), astigmatic (irregular shape of cornea/lens) and/or presbyopic (decreased focusing ability). If there’s a need for any vision correction, either spectacle glasses, contact lenses or laser vision correction would be recommended according to the patient’s lifestyle. An eye health assessment is important to detect sight threatening eye conditions such as cataracts, glaucoma, macular degeneration, retinal problems and general health problems such as diabetes and hypertension.
A typical optometric examination includes:
- Case History: We will review your general health, medications currently prescribed, working environment, hobbies, etc.. You will also be asked about any vision problems you are currently experiencing.
- External Eye Examination: We will examine the external area of the eye for any problems such as chalazions, styes, etc…
- Internal Eye Examination: This part of the examination requires the slit lamp microscope where we will examine the front and back of the eye. Conditions that can be detected inside the eye during this part consists of cataracts, glaucoma, macular degeneration and even systemic conditions such as diabetes and hypertension.
- Tonometry: This is an important test because it measures the pressure inside the eye which is related to glaucoma.
- Vision Test: Using the familiar wall chart we will test your ability to see small fine detail at both distance and near. During this part we will use an instrument called a phoropter to measure the prescription by using a combination of lenses.
- Eye Movement / Functions: Tests will be done to evaluate how well the eyes work together and individually. As well, we will test your ability to change focus, see colour or perceive depth correctly.
All of the above exams are used in conjunction with one another to determine the best type of care needed for your eyes. A sight-test alone cannot adequately provide this information, as it only relies on the refraction portion of your eye health. A refraction cannot tell you whether or not you have an underlying eye health issue that, if left untreated, can seriously effect your overall health. We will chooses the above tests to evaluate your ENTIRE visual system and eye health.
