[LASIK treatment for graft astigmatism].
OBJECTIVE
To analyze the advantages of LASIK as a treatment for postkeratoplasty residual astigmatism.


METHODS
and


METHODS
Retrospective, noncomparative, monocentric study on 14 patients with penetrative keratoplasty. Visual acuity, objective refraction, intraocular pressure, slit lamp biomicroscopy, videotopography, pachymetry, and patient satisfaction were studied before and after surgery.


RESULTS
Refraction was stable 6 months after treatment in 93% (13/14) of the patients. The mean uncorrected visual acuity increased from 0.16 to 0.4. Two out of four patients (14.3%) were retreated because visual acuity did not improve after the first treatment; 35% did not need any optical correction after the intervention. The measured astigmatism showed a significant decrease, from 65% greater than 5 D before treatment to 82% under 2 D after treatment. Only two out of 14 patients (14.3%) were not satisfied. No intraocular or postoperative complications were reported in this study.


CONCLUSIONS
LASIK seems to be an interesting option in the treatment of postkeratoplasty residual astigmatism. This study has shown its efficacy and safety in this indication. Its originality lies in the one-step procedure, with the flap and photoablation done in a single step. However, it is still dependent on the operator and most particularly the equipment (laser, microkeratome, aberrometry).
