What is the most important advancement in laser vision correction to eliminate over, under, and residual astigmatic corrections?
• The most common complication with laser vision correction is unwanted residual prescription, which occurs less than 1% of the time. Elimination of residual prescriptions and accuracy of lasers improved with eye tracking and beam quality. With the advent of Allegretto “flying spot” technology, we were able to reduce our retreatments from about 15% down to less than 1%. The advent of flying spot technology allowed us to maintain the corneal curvature with less breaks and interruptions so that when the pupil widened at night, glare halos and visual distortions were decreased. Data linking has allowed us to develop performance nomograms to determine the specific treatment for each patient prescription. When we switch from broad beam lasers like Nidek and Summit, we were able to determine the range of prescriptions that could be performed with these lasers, which were equal to the more advanced flying spot lasers.
