PURPOSE: To evaluate initial clinical outcomes of laser-assisted in-situ keratomileusis (LASIK) performed with the latest excimer laser (Technolas Teneo 317, Model 2) using an aspheric ablation profile for correcting myopia and myopic astigmatism.

METHODS: This retrospective study included patients who underwent LASIK performed using the new Technolas Teneo 317 Model 2 excimer laser (version 1.28 US SW) by Bausch and Lomb, using the latest aspheric ablation profile. No nomogram adjustments were made, and the patient's manifest refraction was used for the laser treatment. Study parameters included uncorrected and corrected distance visual acuity (UDVA and CDVA), manifest refraction spherical equivalent (MRSE), and astigmatism.

RESULTS: Data from 47 eyes were analyzed. The mean age of 25 patients was 33.4±7.9 years. There were 44% males and 56% females. The mean preoperative CDVA was -0.05±0.09 logMAR and all (100%) eyes had CDVA of 20/30 or better preoperatively. At postoperative 1 month, the uncorrected visual acuity was -0.07±0.07 logMAR, with 100% of eyes achieving UDVA of 20/25 or better. The mean postoperative MRSE was -0.16±0.37 D, with 89.4% and 97.9% of eyes achieving postoperative MRSE within 0.50 D and 1.00 D, respectively. The mean postoperative cylinder was 0.18±0.23 D and 93.6% of eyes showed refractive astigmatism within 0.50 D.

CONCLUSION: LASIK performed with the Teneo 317 Model 2 excimer laser using an aspheric ablation profile for correcting myopia and myopic astigmatism yielded excellent visual and refractive outcomes. These outcomes were achieved using the patient's manifest refraction with no nomogram adjustments.
