Initial femtosecond LASIK results similar between fellowship-trained surgeon, expert surgeon

The results of an expert surgeon’s first 200 myopic LASIK cases performed with a femtosecond laser were statistically comparable to those of a fellowship-trained surgeon, according to a study.
“The transition to Visumax (Carl Zeiss Meditec) femtosecond flap creation produced no visually significant complications in two series of 200 eyes each,” the study authors said. “In addition, previous surgeon experience did not appear to be a benefit over formal fellowship training in LASIK.”
The retrospective comparative case series analyzed the first 200 myopic LASIK femtosecond laser procedures performed by an expert surgeon who had performed 11,637 previous microkeratome LASIK procedures and the first 200 myopic LASIK femtosecond laser procedures performed by a fellowship-trained surgeon who had observed 1,057 surgeries and performed 155 supervised procedures. There was 1 year of follow-up.
There were no statistically significant differences in the results of the procedures.
For the expert surgeon, preop mean spherical equivalent was –4 ± 1.83 D and mean cylinder was 0.81 ± 0.67 D. Postoperatively, 79% of eyes had spherical equivalent of ±0.5 D, 96% of eyes had uncorrected distance visual acuity of 20/20 or better, and 3.5% of eyes lost one line of corrected distance visual acuity.
For the fellowship-trained surgeon, preop mean spherical equivalent was –3.97 ± 1.98 D and mean cylinder was 0.79 ± 0.66 D. Postoperatively, 74% of eyes had spherical equivalent of ±0.5 D, 96% of eyes had uncorrected distance visual acuity of 20/20 or better, and 1.5% of eyes lost one line of corrected distance visual acuity.
