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 the correction of myopia and myopic astigmatism.

Setting

Waring Vision Institute, Mt Pleasant, United States.

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. All (100%) eyes had a preoperative CDVA of 20/30 or better. At postoperative 1 month, mean UDVA was -0.07±0.07 logMAR, with all (100%) eyes achieving UDVA of 20/25 or better. The mean postoperative MRSE was -0.16±0.37 D and 89.4% of eyes achieved MRSE within 0.50 D and 97.9% of eyes achieved postoperative MRSE within 1.00 D. The mean postoperative cylinder was 0.18±0.23 D; 93.6% and 100% of eyes showed refractive astigmatism within 0.50 D and 1.00 D, respectively.

Conclusions

LASIK performed using an aspheric ablation profile of Teneo 317 Model 2 excimer laser for correcting myopia and myopic astigmatism yielded excellent visual and refractive outcomes. These real-world outcomes were achieved without any nomogram adjustments using only the patient’s manifest refraction.
