To evaluate confocal microscopy finding after SMILE surgery by in vivo confocal microscopy and stromal lenticule and stromal interface accuracy planed vs measured. Thirty eyes of 15 patients were evaluated before and 1 month after SMILE surgery by using confocal microscopy. Cellular morphology was studied. Planed stromal lenticule thickness was compared vs measured stromal lenticule thickness after surgery by comparing the total stromal corneal thickness before vs after surgery. Stromal corneal

Activated keratocytes were found before and after stromal corneal interface depth. There was not statistical significant difference between mean planed stromal lenticule vs. post-surgery measured (102.3 ± 25.7 vs. 104.2 ± 29.9 mm; p = 0.73). There was not statistical significant difference between mean planed stromal interface depth vs. post-surgical measured (113.7 ± 8.2 vs. 120.5 ± 17.3 mm; p = 0.058). Confocal microscopy is useful to evaluate changes after SMILE surgery; lenticule thickness and stromal interface depth are exact.
