Ortho-K LK Lens

Orthokeratology is,

The temporary reduction of myopia achieved by the programmed application of contact lenses to reshape the cornea.

Modern orthokeratology (ortho-k) achieves this using specially designed reverse geometry gas permeable [GP] ortho-k shaping lenses worn during sleep.

History of orthokeratology

Orthokeratology, or ortho-k fitting, has been employed since the early 1960s
In one form or another in the United States by George Jessen.
In 1996, Dr.Tom Reim has developed 4 Curve Design ortho-k lens for more effective and safe. Now Lucid Korea has developed 5 Curve Design ortho-k lens for advanced orthokeratology.

Benefits for Ortho-K LK Lens

• The alternative way of myopia management, not throughout surgery
• Higher safety than surgery (PRK), Low critical side effect
• Can be reversible after 3~4 weeks, discontinuing lens wear
• Effective to reduce myopia at every age, especially juvenile
• Can be controlled myopia progression as well as myopia reduction
• Easy to reduce myopia by overnight wear of lenses
• Not necessary to wear lenses at day time
