Abstract Details

Purpose:

To evaluate the efficacy, predictability and safety of Wavefront Optimized (WFO) retreatment of residual refractive errors after previous custom myopic LASIK.

Setting:

Department of Ophthalmology at University of Texas Southwestern Medical Center, Dallas, Texas

Methods:

19 eyes of 14 patients with residual refractive errors after prior custom LASIK (Visx CustomVue™) were assessed at 1, 3, and 6 months after retreatment with the Wavelight ALLEGRETO™ Eye-Q 400 excimer laser platform. UCVA, BSCVA, MRSE, low order aberrations, and complications were assessed. Retreatment was accomplished after lifting the previously established LASIK flap.

Results:

UCVA was improved from pre-treatment 0.6±0.2 to 0.9±0.24 (P <0.001) at 6 months. Pre-retreatment spherical equivalent changed from -0.21± 1.4 (range 1.63 to -3.0D) to -0.37±0.3 (range 0 to -1.0D) at 6 months. At 6 months, 84% of eyes were within ± 0.5D and 100% were within ± 1.00D of target. 37% of eyes gained one and 5% lost one line of BSCVA. Efficacy index (UCVA postoperative/ BCVA preoperative) of retreatments was 0.94 and safety index (BSCVA postoperative/ BSCVA preoperative) was 1.07 at 6 months.

Conclusions:

Results of these analyses indicate that Wavefront Optimized LASIK retreatment provides good refractive and visual outcomes that were not originally achieved with primary Wavefront Guided myopic LASIK. Retreatment with WFO LASIK is safe and the results predictable.
