3D OCT (Ocular Computerized Tomography)

Humphtrey’s FDT


Slit Lamp Biomicroscope


Binocular Indirect Ophthalmoscope


Digital Retinal Camera

This is a laser based scanner which records high-resolution images of the back of your eye in order to monitor the health of your eye. 3D images of the retina, the optic nerve head and the macular are all recorded. This permanent image allows the Doctor to assess the eye for any changes in the layers of the retina which would show active eye disease. The 3D OCT makes the Optometrist better able to detect any subtle changes which may occur over time.

Humphtrey's FDT

The Humphtrey’s FDT is a Visual Field Analyser which is used to detect any areas of vision loss in your vision. This device gives you a quick simple test which highlights any areas of decreased vision which may be found in the Patient’s visual field. This test is important because it can detect early loss of visual field, or peripheral vision, which can be found with conditions such as glaucoma, diabetic retinopathy, optic neuritis or other such disorders.


This is a device used by the Optometrist to measure how your eye processes light. This device measures the your refractive error and determines whether the you need prescription glasses or contact lenses. As well as finding the focus of the your eyes the autorefractor will also measure the curvature of the cornea in order to look for astigmatism or other similar conditions which will affect the focus of your eyes.

Slit Lamp Biomicroscope:

This is a binocular microscope which is used by the Optometrist to exam the surface and internal structures of your eye. The biomicroscope magnifies the eye between 10 and 40 times thereby allowing the Doctor to see any abnormalities of the cornea, the lens, the iris or the minute structures at the back of your eye.


The tonometer is used to measure the Intraocular pressure (IOP) the your eyes. Measurement of eye pressure is important for diagnosing and managing glaucoma. High IOP is a symptom of glaucoma. Early detection of glaucoma can be vital in minimizing peripheral vision loss due to this disease. Yearly measurement of IOP by your Optometrist is an important part of every eye exam.

Binocular Indirect Ophthalmoscope:

The binocular indirect ophthalmoscope (BIO) is used by your Optometrist to view the back of the eye in order to detect any problems with the retina of vitreous humour. This device combines a light source and a microscope which is designed to be worn on the head and which allows both the Doctors eyes to be used thereby giving the Optometrist a 3D view of the eye. This device is very important for detecting retinal problems such as retinal tears or detachments, and it is also useful in and irregularities in surface of the retina. Yearly retinal exams using the BIO are crucial to maintaining good eye health.


The phoropter is an instrument which is used your Optometrist to measure the focus of your eyes. The photopter is a complex construction of gears and lenses which work together to allow the Doctor to dial in various lens combinations in front of your eyes. With the phoropter the Optometrist can determine the accurate subjective focus of your eyes and from this result you Doctor can prescribe the glasses or contact lenes needed to correct your eyesight.
