Clinical study of SMILE on the correction of large astigmatism for 2a

AIM: To observe the surgical results of large astigmatism with small incision lenticule extraction(SMILE)for 2a. <p>METHODS: Totally 33 eyes of 17 consecutive patients were enrolled in this retrospective study, aged from 18 to 36 years old, which included 24 eyes of 12 patients with astigmatis...

description AIM: To observe the surgical results of large astigmatism with small incision lenticule extraction(SMILE)for 2a. <p>METHODS: Totally 33 eyes of 17 consecutive patients were enrolled in this retrospective study, aged from 18 to 36 years old, which included 24 eyes of 12 patients with astigmatism within -3.50D to -4.00D and 9 eyes of 5 patients within -4.25D to -5.00D, 7 eyes of 4 patients with sphere within 0 to +1.00D and 26 eyes of 13 patients within -1.00D to 0. Intended cap diameters was 7.3-7.5mm, lenticule diameter was 6.6-6.8mm, the thickness of cap was 120μm, the surgical incision was 2mm. We observed the results after 1d, 1wk, 1, 3, 6mo, 1 and 2a. Preoperative best corrected visual acuity, spherical equivalent refraction, postoperative uncorrected visual acuity, SimK equivalent value and SimK value was observed. <p>RESULTS: Compared with preoperation, uncorrected visual acuity showed significant difference statistically at 1d postoperatively(<i>P</i><0.05). Compared with 1wk postoperatively, uncorrected visual acuity showed no significant difference statistically at postoperative 1, 3, 6mo, 1 and 2a(<i>P</i>>0.05). Uncorrected visual acuity did not increase or decrease more than two lines. The target diopter was +0.25D. Compared with 1d postoperatively, the spherical equivalent refraction and residual astigmatism showed no significant difference statistically at each postoperative period(<i>P</i>>0.05). postoperative SimK equivalent value and SimK value difference showed no significant difference statistically compared with each postoperative period(<i>P</i>>0.05). <p>CONCLUSION: It is both safe, effective, predictable and stable to correct large astigmatism with SMILE by long-term observation, postoperative 2a. The corneal morphology is good and worthy of clinical application.
