ABSTRACT
PURPOSE:
To report the results of complex wavefront-guided LASIK retreatments.METHODS:
Twenty eyes (15 patients) with histories of conventional LASIK surgery and significant visual complaints of glare and halos due to higher order aberrations were treated. Wavefront-guided retreatments were performed with the LADARVision CustomCornea system (Alcon, Ft Worth, Tex). Pre- and postoperative topographies, wavefront measurements, and subjective reports were analyzed.RESULTS:
Postoperatively, patients had an expanded optical zone, many with improved centration. Lower and higher order aberrations decreased following wavefront-guided ablation. Mean higher order root-mean-square decreased from 1.01 +/- 0.25 microm preoperatively to 0.84 +/- 0.23 microm postoperatively. Mean coma decreased from 0.59 +/- 0.26 microm to 0.43 +/- 0.21 microm. Mean spherical aberration decreased from 0.66 +/- 0.25 microm to 0.54 +/- 0.27 microm. Subjective reports of glare and halo symptoms improved in all patients.CONCLUSIONS:
CustomCornea wavefront-guided treatments are effective in reducing lower and higher order aberrations, expanding optical zones, and improving subjective reports of adverse aberration sequelae such as glare and halos.
