Purpose

PURPOSE

To describe the incidence of LASIK complications related with microkeratomes


Methods

METHODS

  • Retrospective, comparative, interventional case series.

  • We reviewed the records of patients who underwent LASIK at Excimer Laser Santa Cruz, São Paulo, Brazil (65503 eyes).

  • Type of complication,microkeratome and keratometric readingswere studied.


Results t ype of c omplication

RESULTSType of Complication

  • 380 eyes (0.0058%) with an intraoperative complication were identified.

  • Complications included incomplete flaps (0.21%), buttonholes (0.09%), thin flaps (0.06%), and free flaps (0.07%).

RESULTSMicrokeratome

  • The Hansatome was the most common microkeratome used (44.884 eyes; 68,52%), followed bythe Automated CornealShaper-ACS (14.652 eyes, 22,36%) and the Nidek MK-2000 (5967 eyes, 9,1%).

RESULTSMicrokeratome

  • Intraoperative complications were more common with the ACS (1.31%) than with the Hansatome (0.62%) and Nidek MK-2000 (0.64%) (P<.001)

RESULTSMicrokeratome

  • Buttonholes were more frequent with the ACS (0.32%) than with the Hansatome (0.07%) (P<.001) and free flaps were more common with the ACS (0.27%) and MK-2000 (0.3%) than with the Hansatome (0.05%) (P<.001).

RESULTSKeratometric Readings


Conclusions

CONCLUSIONS

  • Complications with mechanical microkeratomes to perform LASIK surgery are extremely rare

  • Most of the complications involve construction of corneal flap

  • There is no significant disadvantage compared with the femtonsecond laser

  • Intraoperative complications were more common with the ACS than with the Hansatome or MK-2000. Buttonholes were most frequent with the ACS, and the Hansatome had the lowest incidence of free flaps
