A comprehensive eye test with Optical Express will identify early signs of eye disease, such as glaucoma and cataracts, as well as checking for a number of other general health conditions. Early diagnosis can prevent or delay more serious damage. Your optometrist will advise you on how frequently you should have an eye test, but for most people, it's every two years.
Your eye test will analyse various aspects of your eye health, including your lifestyle, current prescription, eye pressure and muscle strength – all of which helps your optometrist to formulate a detailed iScan report.
You'll complete a health and lifestyle questionnaire, as many health conditions and lifestyle choices can have an impact on your vision. Armed with this information, your optometrist can then offer you the best care and advice.
An examination of your current glasses will determine their strength and prescription.
A tonometer blows a soft puff of air at your cornea and measures intraocular pressure (IOP). Your IOP levels are then used to assess if you are at risk of glaucoma or other eye conditions and such as retinal detachment.
This computer-controlled technology will calculate how light passes through your eyes to identify your approximate prescription strength.
During this part of your assessment, you'll read differently-sized letters and symbols on an eye chart to show your optometrist how well you can read from a variety of distances.
Your optometrist calculates your prescription strength, comparing the up to date prescription that they have determined with your current glasses (if worn).
Your optometrist will assess how well both eyes work together, both in normal viewing and in respect of the strength and flexibility of your eye muscles.
A high powered microscope is used to examine the front section of your eye, including the eyelids, cornea, conjunctiva and lens.
This detailed assessment places particular focus on the vitreous gel within the eye and the retina. The retina contains the light sensitive cells that help our brain process what we see. Key features assessed include the Optic Nerve and Macula.
Providing precise and thorough diagnostics and imaging, widely recognised as the “Gold Standard” in anterior eye diagnostic technology. The Oculus Pentacam will equip the optometrist with anterior eye imaging of the corneal shape, corneal thickness and natural lens.
The Pentacam® is a rotating Scheimpflug camera system for anterior segment analysis. It measures topography and elevation of the anterior and posterior corneal surface and the corneal thickness. It provides the eye care professional with a wide variety of reports that allow best in class management of corneal health.
There are a number of conditions for which the Oculus Pentacam supports diagnosis, including corneal conditions such as keratoconus and cataracts.
In addition to the detection of the above conditions and the ongoing management of patients who undergo corneal cross linking, the Pentacam can be a useful diagnostic aid in the undertaking of complex contact lens fittings
Optical Coherence Tomography is a high resolution imaging test which helps the eye care professional to understand the health of a patient’s retina. It is used in the diagnosis of many serious eye conditions.
The OCT scanner uses light waves to take cross section images of your retina, allowing your clinician to see distinctive layers of the macula. Further it allows a detailed analysis of the Optic Nerve, a critically important structure for eye health. The images allow early detection of many conditions, to include the following:
- Macula degeneration
- Macula holes
