Superior hinge laser in situ keratomileusis.

Area of Science:

• Ophthalmology
• Surgical Technology

Background:

• Laser in situ keratomileusis (LASIK) is a refractive surgery procedure.
• The Hansatome microkeratome is a device used in LASIK surgery to create corneal flaps.

Purpose of the Study:

• To report the learning curve and experience with the first 400 superior hinge LASIK procedures using the Hansatome microkeratome.
• To evaluate intraoperative complications, management, practical aspects, and effectiveness of the Hansatome microkeratome with the Nidek EC-5000 excimer laser.

Main Methods:

• A total of 400 superior hinge LASIK procedures were performed by the authors.
• Procedures followed the traditional technique described by Lucio Buratto.
• Intraoperative complications were systematically evaluated.

Main Results:

• The majority of LASIK procedures were completed without complications.
• The most frequent complication observed was bleeding from perilimbal corneal vessels.
• Other identified complications were not considered serious.

Conclusions:

• The superior hinge LASIK procedure using the Hansatome microkeratome demonstrated an easy learning curve.
• The technique avoided serious complications typically seen during the initial learning phase.
• The Hansatome microkeratome proved suitable for all treatments performed with the Nidek EC-5000 excimer laser.
