Eyes are our windows to the world and vision is more important than any of our other senses.
A comprehensive eye examination is crucial for identifying your visual needs as well as common diseases such as glaucoma, cataract and retinal problems. Without proper diagnosis and treatment, these diseases can permanently damage our vision. Early detection and pre-emptive action is especially important when it comes to children’s vision and ocular health. We can perform a regular children eye check in Hong Kong on your child to identify issues before they get worse, which could prevent the need for an intense lens
1. Case history
2. Refraction check(Power measurement of Myopia, Hyperopia, astigmatism and Presbyopia)
3. Intra-ocular pressure measurement(Abnormal intra-ocular pressure may result in Glaucoma; early detection is the key to diagnosis and treatment)
4. Binocular vision function test(lazy eye, squint, focusing disorder and abnormal eye movements may be detected via the test)
5. Colour vision test
6. Ocular health and fundus examination
7. Consultation and recommendation
Diabetic Mellitus Retinopathy (DMR) is Hong Kong’s second leading cause of blindness. There are about 200 cases of blindness caused by DMR each year.
DMR is often associated with the cause of other ocular diseases such as cataract, retinal detachment, macular edema, vitreous hemorrhage and secondary glaucoma, so we should pay special attention to it.
DMR in the early stage has no obvious symptoms, hence diabetic patients are recommended to have eye examination at least once a year, in order to avoid any diabetes-induced eye diseases.
Refraction (e.g. myopia, hyperopia or astigmatism, presbyopia)
Intra-ocular Pressure (preliminary assessment of glaucoma)
Binocular Vision (e.g. strabismus, stereopsis)
Color Vision (e.g. color defect)
Ocular and Retinal Condition (Use of atropine eye drops to check fundus hemorrhage, macular edema, new vessels on iris, retina vessel abnormality)
Retina Photography (For comparison of retina conditions on each exam)
Diagnosis and Recommendation
The fluid (aqueous humour) that serves to keep our eyes in good health and shape maintains an intra-ocular pressure of 10-21mmHg. Abnormal intra-ocular pressure may damage the optic nerve head, resulting in glaucoma.
Those with high myopia or hyperopia, diabetes, a family history of the disease, prolonged use of steroid, and high intra-ocular pressure are at greater risk of developing the disease. Like any health issue, early detection is key. A glaucoma examination in our Hong Kong centre is recommended on a regular basis for diagnosis and treatment at an early age.

If you would like more information on how a glaucoma examination is performed, or would like to make a booking with a member of our team, please get in touch with us today. We have two locations for your convenience. Appointments can be made over the phone or via our online form.
We can also check for other conditions, such as lazy eyes in children, and can offer solutions such as orthokeratology, which aims to assist those with myopia.
Dry eyes is a condition in which the eye fails to produce sufficient or good quality tears, resulting in the drying up of the ocular surface. Symptoms of dry eyes including eye dryness, foreign body sensation, photophobia (sensitivity to light), tearing, burning sensation or fatigue, and even impaired vision. Severe dry eye can lead to a corneal ulceration or inflammation of eyes.
Dry eyes are caused by a number of factors, including age-related lacrimal gland dysfunction, over exposure to indoor air-conditioned environment, excessive reading on electronic visual displays, insufficient rest, usage of some drugs, prolonged contact lens use, and LASIK eye surgery.
Measurement of Tear Output Level (Attaching a strip of filter paper to the lower eyelid to test the fluid level)
Eyelid and Cornea Checking
Diagnosis and Recommendation
Optometrists will recommend different treatments to ease the dry eye problem based on their respective conditions, including prescription of artificial tears, eye supplement or dry eye treatment device.
Visual field test is used to measure the field (scope) and sensitivity of vision, playing a vital role in diagnosing glaucoma, retinitis pigmentosa and other diseases that influence visual field (e.g. brain tumours). A good visual field is particularly vital to drivers as it helps to ensure driving safety.
Eye diseases (e.g. glaucoma, cataract, retinal detachment and macular degeneration) that influence the visual field may not have obvious symptoms at their early stage. This might lead to a delay in detection and treatment of the diseases and result in permanent visual damage.
Our centre is equipped with a world-class Computerised Visual Field Analyzer, which can effectively measure visual sensitivity as well as visual field.
During the test, you are required to cover one of your eyes, with the uncovered one focusing on detecting flashes of light. The computer programme will project different brightness and sizes of light spots in varies locations inside the equipment, while you need to press buttons based on the flashes you see. After testing both eyes, the system will analyse the collected data, comparing it with the norm data and analyse your eye condition.
光學相干斷層掃描(OCT)是一種非接觸式、 非侵入性光學診斷技術，儀器利用光學反射對角膜、虹膜、晶狀體、視網膜、視神經頭、視神經組織、黃斑點等進行高清晰度 (High Definition) 的橫切面分析，透過檢查能取得精確的數據，幫助視光師有效評估客人的視覺神經及黃斑區眼睛。

1.Our optometrists will determine the necessary eye tests and procedures for you based on your eye conditions, and will provide you with the relevant test results.
2.Our optometrists may apply mydriatic eyedrops to dilate your pupils during the eye examination. After dilation, your eyes will become more sensitive to light and your near vision may be blurred temporarily. We advise you to bring a pair of sunglasses or an umbrella to protect your eyes from light. In addition, you should avoid driving, operating any machinery and doing paperwork after pupil dilation. In general, the drugs effect will only last for 4-6 hours.
3.It is not advisable to wear contact lens immediately after eye examinations as diagnostic drops may be applied.
