Orthokeratology, or Ortho-K, is a non-surgical vision correction method using specially designed rigid contact lenses that gently reshape the cornea overnight. You wear them while you sleep and wake up with clear vision — no glasses or daytime lenses needed.
How does Ortho-K work?
The lenses apply gentle hydraulic pressure to the epithelial cells of the cornea, temporarily flattening the central zone. This changes how light focuses on the retina, correcting myopia. The effect lasts through the day and reverses if you stop wearing the lenses.
Is it safe for children?
Yes. Ortho-K has been used for over 20 years and multiple studies confirm its safety for children aged 6 and above. It is one of the most effective methods to slow axial eye growth.
Who is suitable?
- Myopia up to -6.00D (sometimes higher)
- Children whose prescription is increasing each year
- Anyone who wants freedom from daytime correction
Ortho-K at Second Sight, first in Rajasthan
Dr. Ashima Bhargava introduced Orthokeratology to Rajasthan. We have been fitting Ortho-K lenses since the clinic's founding and have experience with a wide range of prescriptions and corneal types. Every fitting starts with detailed topography, and we use only internationally validated Ortho-K lens designs. We follow up regularly to monitor both the correction and the myopia progression over time.
