Contact Lens Fitting

All first time contact lens wearers should have a trial period with the new lenses followed by an in-the-eye assessment to ensure the fit is safe. A fit that is too loose or too tight may cause problems over the long term. Too loose can result in comfort, vision, and stability issues (lenses popping out unexpectedly). Too tight is more of a concern. Most wearers will have no symptoms. In fact, too tight with its lack of movement often feels great…like there is no lens in there at all. And while the newest high oxygen transmission lenses go a long way in reducing possible corneal damage from tight fitting lenses, you still need a little movement to allow debris to flush from under the lens. Failure to do so will create a situation of low grade long term (depending on wearing schedule) corneal stress. At best this just means at some point in the future you will need to cease (or greatly reduce) lens wear. At worse the stress reduces the corneal health so significantly that it becomes vulnerable to corneal ulcers and subsequent permanent and often significant loss of vision.

It is also good to occasional recheck the long term safety of the lens wear. This is most easily done by wearing your lenses when doing your regular eye exam

Pachymetry

Pachymetry is the measurement of the thickness of the front surface of the eye (the cornea). We have both an optical and an ultrasound pachymeter. The optical reading is quick and non-invasive and is now part of the ‘pre-test’ procedure. The ultrasound measurement is more reliable and will be used to recheck the screening test when necessary. This measurement is important in the diagnoses of glaucoma and corneal diseases such as keratoconus. This procedure is also important for patients being considered for refractive surgery such as LASIK

Ocular Coherence

A laser imaging system that provides a three dimensional view of all ten layers of the retinal structure and beyond to the choroid (the main blood supply to the retina). The OCT has greatly improved our understanding, diagnosis and treatment of most retinal disease. It is invaluable in the early diagnosis and in monitoring the effectiveness of the treatment of macular degeneration, the glaucomas, diabetic retinal vascular disease and most other retinal disease processes.

Digital Anterior

By adding a camera to the bio-microscope we can make a permanent record of any structures observed during the examination of the external anatomy of the eye.

Digital Retina

This specialized camera provides a very high resolution permeant record of the structures of the inside back of the eye. Establishing a baseline photographic record is very valuable at future eye examinations to be able to compare for any subtle changes. This is particular useful in diabetic retinal disease, glaucoma and macular changes. Plus the photograph may be able to detect subtle problems that a visual examination may not see.

Visual Field

The standard vision test examines the structures, health and function of the eyeball. The rest of your visual system (the posterior half of the optic nerve, the chasm where your optic nerves divide and organize into right and left sides, the neural path of vision through the brain and finally the optic cortex – the part of your brain that processes vision) – are not assessed as part of the regular eye examination. Visual field testing checks the function of all these ‘upper’ vision structures. It is able to detect vision losses that can occur due to brain structure problems such as trauma, stroke, aneurisms and tumors. It is also invaluable in assisting in early glaucoma detection since that is really an optic nerve disease. It is advisable that everyone do a full visual field assessment to screen for hidden problems and establish their own ‘normal’ baseline.

Opthalmoscopy

Ophthalmoscopy is an internal view of the eye which looks for cataract development, vitreous changes, glaucomatous damage to the optic nerve, retinal vascular disease (i.e. diabetes and high blood pressure), risk of retinal detachment, macular degeneration and other retinal disorders.

Bio Microscopy

Bio-microscopy is a magnified stereo view of the external anatomy of the eye. It also provides an ‘estimate’ of the angle in the anterior chamber to determine your relative risk of an acute glaucoma attack – a sudden extreme rise of the pressure in the eye. It assesses eyelid structures, the surface of the eye, it can also provide a view into the front of the eye to see the iris (the coloured part of the eye) and just behind the iris to see a part of the internal lens. With the addition of dilating eye drops and an accessory lens, the bio-microscope can be an excellent tool to get magnified stereo views of structures of the inside back of the eye.

Eye Exams

Normal Eye Exam Includes:

  • -Refraction i.e. gets the numbers required for a final glasses prescription and starting point for fitting contact lenses
  • -Assess binocularity – or how well your two eyes work together
  • -Ocular health screening which includes the fallowing procedures
    • Tonometry:-a measure of the fluid pressure inside the eye. (IOP -intra ocular pressure).
    • Bio-microscopy: This is a magnified stereo view of the external anatomy of the eye.
    • Ophthalmoscopy: A view of the structures inside the eye.
