Orthokeratology involves a three-step process:
1) the initial examination, where your optometrist or ophthalmologist will use a Topograph to determine the refraction error of the cornea
2) the fitting, which may happen on the same day, where your eye care professional will select a series of up to three strengths of custom Ortho-K prescription contacts.
3) the one-to-two-week treatment phase where candidates use their prescription contacts while sleeping for at least six to eight consecutive hours each night.
Candidates will wear disposable soft lenses or glasses throughout the day during the correction phase. On completion of the treatment, only the prescribed overnight contacts need to be worn. Occasionally, candidates experience mild glaring and haloes around bright light. Remember, there is always the risk of infection without proper eye and lens care, so practice good hygiene and schedule routine follow-up eye appointments!
