What are hard contact lenses?

Hard contact lenses are a rigid lens that is made of a gas-permeable material to allow oxygen to pass through and reach the eyes. The two main types of hard lenses are conventional hard lenses (PMMA) and rigid gas-permeable lenses (RGP).

Are hard lenses better than soft?

What are the disadvantages of ortho-k?

Disadvantages of ortho-k lens wearing:

  • Wearers should strictly follow the instructions given by the optometrist, non-compliance could result in corneal infection and possible vision loss.
  • Parents and wearers have to spend more time initially for ortho-k lens fitting and follow-ups.
  • Ortho-k cannot cure myopia.

Is ortho-k better than LASIK?
