Are there more risks associated with higher prescriptions?
Yes. The two areas where higher risks are associated with higher prescriptions are night vision disturbances (halos and starbursts) and corneal haze. One of Professor Reinstein’s main research focuses over the last 8 years has been the correction (and prevention) of night vision disturbances. Professor Reinstein has developed protocols for correcting and preventing halo and starburst effects even when treating very high prescriptions and patients with large pupils. Zeiss incorporates many of his findings in the commercially available Carl Zeiss Meditec MEL 80 excimer laser system, in use at the clinic today. It is therefore extremely rare for patients in our practice to end up with night vision disturbances. We confidently believe that we have the most sophisticated systems in place for preventing or treating night vision disturbances. The risk of haze in PRK / LASEK increases the higher the prescription to be treated, but is also dependent on the smoothness of the surface created by t
