Orthokeratology lenses: custom manufacturing and quality control at Astana Vision.

Orthokeratology (night) lenses are a high-tech solution for vision correction without surgery and without wearing glasses during the day. Their key feature is that each lens is manufactured strictly individually, based on the patient’s ocular parameters.

An individual approach is the foundation of effectiveness
Unlike standard soft contact lenses, orthokeratology lenses are never «off‑the‑shelf.»
When fitting them, the following are taken into account:

• corneal shape

• degree of myopia or astigmatism

• tear film characteristics

• patient’s age and lifestyle

Based on these data, a unique lens design is created that ensures safe and effective corneal reshaping during sleep.

In‑house laboratory at Astana Vision
The Astana Vision clinic network has its own contact lens manufacturing laboratory. This provides important advantages:

• full quality control at every stage

• reduced production times

• ability to make precise adjustments to lenses if needed

• independence from third‑party manufacturers

Production is carried out at a specialised centre:

World‑class technology
The laboratory uses equipment from DAC International (USA) – a recognised global leader in high‑precision CNC lathes for contact lens manufacturing.

The use of these technologies enables:

• micron‑level machining accuracy

• perfect lens geometry

• consistent quality from product to product

• production of lenses of any complexity, including orthokeratology lenses

Quality and safety assurance
Thanks to the combination of:

• customised design

• in‑house production

• state‑of‑the‑art equipment

Astana Vision ensures a high level of safety and predictable vision correction outcomes.

The patient receives not just a lens, but a personalised medical solution tailored to their visual system.

In conclusion
Orthokeratology lenses are not a mass‑produced product, but the result of precision engineering and medical expertise.
The availability of an in‑house laboratory and the use of DAC International technology allow Astana Vision to control the entire process – from diagnostics to the finished product.

This means one thing:
the patient receives maximum accuracy, comfort, and confidence in the result.
