Refractive results with SMILE using lower energy settings in the United States.

Refractive results with SMILE using lower energy settings in the United States.

<h4>Purpose</h4>To report the visual and refractive results of small incision lenticule extraction (SMILE) with low energy settings in the United States (US) and to evaluate outcomes for low astigmatism treatment.<h4>Setting</h4>Private clinical practice.<h4>Design</...

Inclusion criteria included all patients between the ages of 19-39 with myopic astigmatism up to -11.25 diopters (D) spherical equivalent (sphere up to -10.00 D, astigmatism up to -3.00 D), and corrected distance visual acuity of at least 20/25.

At last visit, 431 eyes (93%) achieved UCVA of 20/20 or better, and 461 eyes (99.8%) were 20/25 or better. Ninety-seven (21%) eyes gained at least 1 Snellen line of corrected distance visual acuity and no eyes lost 2 or more lines.
