Purpose
This study aims to assess the treatment outcomes of patients with thin corneas who underwent combined refractive surgery using the SMILE Xtra technique for Myopia and Myopic Astigmatism .
Setting
Batı Göz Hospital
Methods
This study was a retrospective study that included 33 eyes of 17 patients with Myopia and Myopic Astigmatism. The eyes were corrected using SMILE Xtra. The outcomes were evaluated postoperatively.
Results
Central corneal thickness was 492.2±15.9 ( 465-518) μm preoperatively. The median and IQR (interquartile range) spherical equivalent (SEQ) values reduced from -3.50 (-5.62-2.37) D preoperatively to -0.50 (0-0.75)in the last follow-up (p < 0.05). At the last follow-up, 28 eyes (84.8 %) were within ±1.0 D of attempted correction.Best corrected visual acuity loss was not detected in any patient. Keratectasia was not observed throughout the follow-up period.
Conclusions
Combining corneal cross-linking with SMILE procedure (SMILE Xtra) can be an optional therapy to prevent ectasia in high-risk patients with thin cornea in myopia and myopic astigmatism correction.
