Abstract Details

Purpose:

Neuro Track system eliminates cyclotorsion at its source by controlling optokinesis, a neural response of the visual system to use spatial cues to stabilize retinal images. The purpose of this study was to compare refractive outcomes between Wavefront-optimized laser in situ keratomileusis (LASIK) using Neuro Track system (Neuro Track LASIK) and Wavefront-guided LASIK using iris registration (WF LASIK).

Setting:

Inouye Eye Hospital Tokyo, Japan

Methods:

Neuro Track LASIK group comprised 16 eyes of 13 patients and WF LASIK group comprised 17 eyes of 14 patients. All eyes had astigmatism of 2 diopter (D) or more. Neurotrack LASIK was performed using EX500 excimer laser with Neuro Track system.WF LASIK was performed using VISX S4 IR excimer laser with iris registration. Pre- and 6 months postoperatively, uncorrected (UDVA) and corrected (CDVA) distance visual acuities, residual astigmatism, and refractive outcomes were examined.

Results:

In Neuro Track LASIK group, postoperative mean UDVA and CDVA in LogMAR were -0.155±0.04 and -0.162±0.04. Mean residual astigmatism was 0.05±0.14 D. Mean safety index and efficacy index were 1.09±0.15 and 1.08±0.16. In WF LASIK group, postoperative mean UDVA and CDVA were -0.055±0.13 and -0.141±0.05. Mean residual astigmatism was 0.68±0.53 D. Mean safety index and efficacy index were 1.08±0.19 and 0.92±0.28. UDVA and residual astigmatism were significantly better in the Neuro Track LASIK group than in the WF LASIK group (P=0.0136, P<0.0001).

Conclusions:

Refractive outcomes were excellent in both Neuro Track LASIK and WF LASIK. However, Neuro Track LASIK provided significantly better UDVA and residual astigmatism than WF LASIK.
