Clear Vision Through Sleep
A thin orthokeratology lens
has become an effective partner
for many adolescents
in controlling myopia progression.
With numerous OK lens brands available,
should brand reputation be a priority?
To answer this, let’s first understand how OK lenses work.
Before Orthokeratology
Light passes through the cornea and lens, but in myopic eyes, the focal point falls in front of the retina, causing blurred vision.
During Orthokeratology
Wearing OK lenses for 8–12 hours overnight gently reshapes the corneal epithelium via fluid dynamics, flattening the central cornea and adjusting curvature to focus light precisely on the retina.
After Orthokeratology
Removing lenses in the morning maintains the flattened corneal shape temporarily, sustaining clear vision and slowing axial elongation to control myopia progression.
OK lenses rely on corneal remodeling, but individual corneal shapes vary—some are perfectly curved, others resemble a "straw hat." These differences impact effectiveness, even with the same brand or product.
No "Best" Brand—Only the "Best Fit"
How to choose the most suitable OK lens? Practical tips below!
TIP 01: Let Your Eye Data Guide the Decision
OK lens fitting is a highly specialized medical process. Beyond clinical evaluation, comprehensive tests are required:
Tear quality assessment
Intraocular pressure measurement
Corneal topography mapping
Corneal endothelial cell count
Axial length measurement
Retinal examination
These data help doctors evaluate ocular health and match lens parameters (oxygen permeability, refractive index, wettability) for personalized fitting.
TIP 02: Avoid Overvaluing Others’ Reviews
Parents often ask for specific brands based on friends’ recommendations or online reviews. However, OK lens efficacy varies by individual corneal anatomy and myopia severity. Others’ experiences are references, not decisive factors—avoid blind imitation.
TIP 03: Trial Fitting Is Essential
A trial fitting ensures precise lens parameters, comfort, and effectiveness. It also tests tolerance and refines lens selection based on the child’s unique corneal features and brand-specific designs.
TIP 04: Optimize Efficiency with Professional Services
