Just to play devil's advocate:burnt69 wrote: ↑ Dry eye is greater with LASIK than with PRK. PRK, especially at those higher prescriptions, allows for larger treatment error. PRK is less susceptible to technical error. If there's slight overtreatment or undertreatment, steroid drops can be individually adjusted to shift the result, while LASIK, once the treatment is locked in, its done, and further surgical intervention would be required. And less risk of the dreaded side effect of ectasia wih PRK.
PLEC, which used to do most of its procedures as LASIK, actually found statistically better visual results with PRK:
However, the higher the refractive error, the greater the risk of post operative corneal haze with PRK.
How common is ectasia now that laser centers screen everyone with corneal topography? I would imagine very low. Any sign of abnormal corneal thinning is flagged and disqualifies you as a candidate.
