A full service care is essential to a successful contact lens fitting. Before starting contact lens trials, you will go through eye examination and evaluation of the suitability for contact lens wear. Once suitability is confirmed, Dr. Hsiao will decide the right kind of lens design, material and prescription for you. You will then receive the lens care kits, instruction on lens care regiments, and schedule for follow up visits.
- 矯正的成效完全取決於:醫師對於硬式隱形眼鏡的臨床經驗及專業知識, 精密的測量儀器, 事前的全面評估和定期的複診.
- 可能會引起一般隱形眼鏡相關的問題;例如眼睛過敏,角膜表皮磨損等. 所以定期的複診是確保長期配戴成功的必要條件
Ok lens is made of high rigid gas permeable lens material with a double reverse geometry lens design. It is designed to compress and reshape the corneal curvature in order to temporally correct the refractive error and to retard the myopia progression. The patient only needs to wear the lens during sleep hours and will have clear vision throughout all day after lens removal in the morning without any optical aids.
In General, an Ok lens can easily correct myopia prescription up to -3.00D, and maybe up to -5.00D~-5.50D depends on individual’s corneal condition. According to many international journals and Dr. Hsiao’s research, wearing Ok lenses can effectively slow down the myopia progression by at least 50 %.
Thorough eye examination, accurate refraction, and pre-fitting case history are all part of Ok fitting screening tests. The Ok fitting procedures include fluorescence staining, corneal evaluation, and lens centration, lens movement, lens congruency on the cornea. All these are done to make sure no damage could happen to cornea due to lens wear.
Ok lens is not just a special type of contact lenses, instead, it is a customized corrective lens based on fitter’s experience and technique towards Ok lens fitting.
Preschool (age 3~5): look out for the conditions such as crossed eyes (strabismus) and lazy eye (amblyopia). These vision problems can’t be fully corrected by eyeglasses alone, special treatments are required.
School Children (age 6~18): The most common vision problems are nearsightedness (myopia) and astigmatism. Other conditions such as eye coordination or accommodation may also present.
- 越小年齡罹患近視, 近視增加越快, 而且越容易在將來變成高度近視群.
- 青少年在未滿18-19歲前, 近視都很有可能繼續加深
- 配戴眼鏡或軟式隱形眼鏡, 並不會增快或減緩近視加深的速度
- 綜合以上各點, 最好的方法就是在近視加深前抑制它

Good habits to slow down myopia progression:
Daily outdoor activity –preferable > 2 hours under the sun
At least 30-45 cm reading distance
Proper reading posture
Avoid long period time of near distance work
Adequate reading lighting source
Take a short break after 30 minutes of reading
Proper viewing distance when watching TV (4~5x of the TV screen length)
Vitamin D intake
Less use of red color and more use of blue color lighting source
Regular eye examination
Normally, the brain receives signals from both eyes at the same time which means both eyes working together by pointing at the same place. Proper eye alignment is essential for adequate depth perception and avoiding seeing double images. Binocular vision problems are among the most common visual disorders. Patients often experience symptoms such as blur vision, eye strain, discomfort, and diplopia. It is very likely the turned eye will develop a lazy eye in the long run. There are many treatment options for binocular vision anomalies, and they are spectacle lens, contact lens, eye surgery, prism and vision therapy.
comprehensive eye examination
The most important part of preventive healthy vision care is anannular comprehensive eye examination. Optometrists detect and manage problems and conditions of the eye and making sure you get the most from your vision.
Many eye and vision problems have no obvious signs or symptoms. Early diagnosis and treatment of eye and vision problems can help prevent vision loss.
The tests to be conducted during an eye examination depend on patient’s signs and symptoms, along with the optometrist’s professional judgment. A comprehensive eye examination may include, but is not limited to, the following tests:
Patient History, Visual Acuity, Preliminary tests, Keratometry, Refraction, Eye Focusing, Eye Teaming, and Eye Movement Testing, Eye Health Evaluation and Supplemental tests
The Canadian Association of Optometrists recommends a thorough eye examination. This involves a comprehensive array of investigations to determine current condition of your vision and eye health. Then the optometrists can make recommendations based on results of the followings:
1. A complete ocular and general health history, including medication taken recently
2. Inspection of the exterior of the eyes and surrounding areas
3. Inspections of the interior of the eyes for signs of certain eye or systemic diseases
4. Tests of visual acuity, the refractive status, and any optic-related visual anomalies
5. Check of eye coordination of eye muscle control
6. Test of the ability of eyes to focus, when changing the working distance
7. Special tests such as color perception, depth perception, field of vision visual/perceptual skill
After completing the examination, corrective lenses (spectacle or contact lenses), vision therapy or other types of treatment may be prescribed
Pre and Post Lasik evaluation
Lasik is a surgical procedure which uses a blade or laser to cut a flap in the cornea and then uses a laser to reshape the corneal tissue underneath. Lasik can be used to correct vision in people with myopia, hyperopia, and astigmatism. Pre Lasik assessment is important to rule out any risk factors and to confirm whether the patient is a good candidate for the surgery. Post Lasik evaluation is to make sure the cornea is recovering from the surgery properly and the refractive status is fully corrected.
