Consistency in the performance of four inspection instruments used in femtosecond laser-assisted cataract surgery for corneal astigmatism correction.

Abstract To observe the consistency of four examination devices in femtosecond laser-assisted cataract surgery for femtosecond correction of corneal astigmatism. We selected 31 patients (40 eyes) who chose femtosecond laser-assisted cataract surgery combined with corneal astigmatism for 1.0-3.5 days as the study object. Femtosecond laser combined with cataract phacoemulsification surgery was performed on patients with corneal lysis incision for astigmatism correction at no additional cost. Computer optometry, IOL-Master700, OPD ScanIII and Pentacam HR were used before surgery, 1 day, 1 week, 1 month and 3 months after surgery. The result was a high degree of agreement among the four instruments, showing a high positive correlation (r > 0.7).
