Background: To evaluate re-treatments following laser in situ keratomileusis.

Patients and Methods: Forty-eight eyes of twenty-nine patients, who were under- or overcorrected more than 1 diopter (D) of spherical equivalent after LASIK using the Hansatome/C-LASIK 217 excimer laser system were examined. All eyes were re-treated by lifting the LASIK flap three to four months after primary LASIK.

Results: Apart from three cases, both over- and undercorrected patients who had undergone LASIK for myopic astigmatism, achieved spherical equivalents ± 1 D around emmetropia. Additionally, in three patients who were retreated because of undercorrection after LASIK for hyperopic astigmatism, refraction could be enhanced.

Conclusion: In case of undercorrection, re-treatment within the first four months is a sufficient procedure to improve the refractive results after LASIK. Without the use of a microkeratome, the technique is more simple than primary LASIK. Severe complications did not occur in our case series treated.
