There are many pilots, fire fighters and police officers who have benefitted from orthokeratology over the last 35 years.
With new materials recently introduced, advanced fitting techniques and lens designs, high degrees of myopia (nearsightedness) and astigmatism may be significantly reduced or eliminated in a relatively short amount of time. Periodic monitoring will be necessary and lens changes may be needed over a period of several months as the cornea adjusts to its new shape.
Orthokeratology is a preferable alternative to PRK (laser refractive surgery) and RK incisimal refractive surgery. Both of these invasive procedures carry inherent risks which may have life effects frequently reported in patients who have had PRK and RK areiphotophobia, glare especially at night, corneal clouding and scarring, fluctuating visual acuity within a 24 hour period, interval ocular inflammation and infection cataracts and even loss of the eye have all been reported.
In addition, in studies done on patients who have had refractive eye surgery, 3% end up with permanent loss of best corrected visual acuity and 30% still need glasses. Post-operatively, 43% of the operated eyes also became far sighted at an earlier age than anticipated and show no evidence of stopping 10 years after the surgery.
In conclusion, if you want to improve your vision and get rid of your eyeglasses, think orthokeratology or contact lenses, not RK or PRK.
