Superior hinge laser in situ keratomileusis.
OBJECTIVE
The learning curve and experience with the first 400 superior hinge laser in situ keratomileusis (LASIK) procedures performed with the Hansatome microkeratome are reported. We present information on intraoperative complications, management, practical aspects, and the effectiveness of this microkeratome used with the Nidek EC-5000 excimer laser.


METHODS
All LASIK procedures were performed by the authors, according to the traditional technique described by Lucio Buratto. Intraoperative complications in the first 400 superior hinge LASIK procedures were evaluated.


RESULTS
Most procedures had no complications. Bleeding of the perilimbal corneal vessels was the most frequent complication; other complications observed were not considered serious.


CONCLUSIONS
The superior hinge LASIK procedure with the Hansatome showed an easy learning curve, without the serious complications that frequently occur in this phase. It was suitable for all the treatments with the Nidek EC-5000 excimer laser.
