Abstract
Purpose :
To evaluate the visual and refractive outcome of 460 eyes treated with small-incision lenticule extraction (SMILE) in patients with myopic astigmatism
Methods :
A SMILE procedure was performed. Outcome measures were corrected distance (CDVA) and uncorrected distance (UDVA) visual acuity; induced torsion and achieved corrections of sphere and cylinder were determined.
Results :
460 eyes of 234 patients received ≥ 2.0 D astigmatic correction. Preoperative mean spherical equivalent was −6.25 D, 3.27 SD, and 6-year postop spherical equivalent was +0.24 D, 0.45 SD. Refractive stability was achieved within 6 weeks. 72 months after surgery, 97% of all cases had a UDVA of 20/25 or better.
Conclusions :
SMILE appears to be a predictable and effective procedure to treat myopic astigmatism; a small, significant undercorrection of the astigmatic error is present, specially in astigmatism over 3.0 D.
