Chapter 3: Incisional Corneal Surgery
Incisional Correction of Astigmatism
The instruments used in AKs and LRIs are similar. Adjustable diamond blades are more often used in AKs. Preset diamond blades are more often used in LRI surgical procedures (Fig 3-5), although adjustable blades may be used. The femtosecond laser has been adapted to create peripheral arcuate incisions. These incisions may be titratable, as only part of the incision may be opened initially, followed by a larger area later if there is a need for greater astigmatic correction.
