[Bilateral simultaneous LASIK. Pro and contra].

Until recently simultaneous bilateral laser in situ keratomileusis (LASIK) was regarded as contraindicated in Germany. However, the procedure was sporadically performed, because it offers patient comfort and is more cost effective than sequential LASIK. Even though the complication rate is below the calculated rate of 0.01%, bilateral complications may have catastrophic effects on the patient. In addition, there is the theoretical disadvantage that the results from the first eye cannot be used for the second eye. However, this effect has yet to be clinically proven.
