Laser in situ keratomileusis: three unexpected complications.
OBJECTIVE
To report unexpected outcomes in three patients after uneventful laser in situ keratomileusis (LASIK) performed using the Nidek EC-5000 excimer laser and the Hansatome microkeratome (Bausch & Lomb Surgical).


METHODS
LASIK was performed with the Nidek EC-5000 excimer laser and the Hansatome microkeratome (Bausch & Lomb Surgical) in three patients.


RESULTS
In three patients, unexpected outcomes were observed. One patient treated for -3.00 D of myopia presented with a central island. One patient treated for +2.00 D (+1.00 x 90 degrees) of hyperopia in both eyes ended up emmetropic in one eye and overcorrected in the fellow eye. The third patient with -12.00 D (-2.00 x 180 degrees) of myopia was treated as -8.60 -1.00 x 180 degrees and at last examination was +4.00 D. During these sessions, all other patients treated were within +/-0.50 D of emmetropia.


CONCLUSIONS
After LASIK with the Nidek EC-5000 excimer laser and the Hansatome microkeratome (Bausch & Lomb Surgical), unexpected outcomes may still occur, despite controlling all the usual variables.
