Orthokeratology (Ortho-K) Lens Fitting and Trial Programme

Orthokeratology (Ortho-K) Lens Fitting and Trial Programme

• Orthokeratology (Ortho-K) Lenses are specially designed rigid gas-permeable contact lenses. Children wear the Ortho-K lenses at night while sleeping, the cornea will be re-shaped temperately and hence refractive error (mainly myopia and astigmatism) will be corrected. It slows down myopia progression and most of the children could enjoy clear vision without glasses or contact lenses at day time after removing the OK lenses. It is ideal for sports and physical activities.
• Orthokeratology (Ortho-K) Lens Fitting and Trial Programme includes a detailed eye examination to assess ocular health, measure necessary structural and vision data. Trial of Ortho-K lenses is also provided to allow children to experience Ortho-K lens wear and optometrist can observe the corneal responses. This helps to evaluate the suitability of fitting Ortho-K lenses and design an effective solution for myopia management.

Important Reminder: Pupil dilation maybe needed during eye exam. We suggest you to put on sunglasses, avoid driving, using computer and reading after eye examination. In general, ocular function will resume normal after 4-6 hours.

Orthokeratology (Ortho-K) Lens Fitting and Trial Programme Included:

1. Case history
   Identify poor visual habit and vision problems, evaluate the potential risk and necessary measures of fitting Ortho-K lenses
   
   
2. Cyclopedic Refraction check*
   Children often with active accommodation. Cyclopedic refraction allows more precise assessment of myopia, hyperopia, astigmatism, etc. It helps to eliminate error caused by pseudo-myopia and give better assessment of refractive errors
   
   
3. Visual acuity (VA)
   Check the distance and near VA, assess risk of amblyopia and evaluate if vision fulfills the requirement for effective learning
   
   
4. Intra-ocular pressure (IOP) measurement
   Rise in IOP may result in glaucoma which may lead to blindness if left untreated
   
   
5. Binocular vision assessment
   Visual function assessment on squint, accommodation (ability in changing focus) and motility (alignment of eyes in tracking target). Binocular vision problems may lead to tired eyes, blurry vision and double vision, which may affect learning and development of the visual system
   
   
6. Colour vision test
   Test on ability to differentiate colors, colour vision problem may affect learning and future career selection
   
   
7. Stereopsis (depth perception)
   Good stereoacuity is important for precise judgment of distance and three-dimension perception, it is also important for sport performance
   
   
8. Slit lamp examination on outer and inner eye structures
   Assessment of sensitive eyes (itchiness), corneal health, congenital cataract, etc.
   Figure out any eye health related contraindication to Ortho-K lenses wear
   
   
9. Dilated fundus examination (retina image capture with digital fundus camera)
   Assessment of the central and peripheral retina, can reveal some severe eye diseases such as retinal tear, glaucoma, diabetic retinopathy and macular degeneration. Digital retinal image is captured for photo documentation
   
   
10. Corneal topography
    Obtains 3D map of the corneal curvature to obtain data such as base curvature and power of the Ortho-K lenses needed
    
    
11. Trial of Ortho-K lenses
    Same-day trial is provided to evaluate the corneal response (change in corneal curvature and refractive errors) to Orhto-K lens wear, obtain data for ordering the best fit Ortho-K lenses for myopia management programme
    
    
12. Consultation and recommendation
    Detailed explanation on the restrains, pros and cons of using Ortho-K lenses for myopia management
    
    
13. Introduction of other myopia management solutions, such as soft contact lenses for myopia management, spectacle lenses for myopia management and atropine eyedrops (if Ortho-K lens is not applicable)
