Orthokeratology : Bangkok, Thailand(AT181)

Orthokeratology (ortho-k) is the fitting of specially designed gas permeable contact lenses that you wear overnight. While you are asleep, the lenses gently reshape the front surface of your eye (cornea) so you can see clearly the following day after you remove the lenses when you wake up.
Only highly “breathable” GP lenses that have been FDA approved for overnight wear should be used for orthokeratology.

Ortho-k lenses are prescribed for two purposes:
• To correct refractive errors (primarily nearsightedness, but also astigmatism and hyperopia). In some cases, ortho-k also is used to correct presbyopia.
• To slow the progression of childhood myopia.
