ABSTRACT
AIM:
To contrast analysis of postoperative variation of corneal posterior surface heights after Femtosecond LASlK ( FS - LASlK ) and small incision lenticule extraction ( SMlLE) for high myopia. ●METHODS:
Sixty-seven cases of high myopic patients (132 eyes) operated with laser corneal refractive in our hospital from May to Dec. in 2015 (-6. 00D≤spherical equivalent degree≤-10. 00D) were selected and divided into FS-LASlK group and SMlLE group. The thickness of corneal flaps at FS-LASlK and the thickness of map at SMlLE were designed to be 110μm. Corneal posterior surface heights were examined by Pentacam at preoperation, postoperative 3 and 6mo after FS-LASlK and SMlLE operation. Surface height changes after preoperative, postoperative 3 and 6mo were compared by measuring Pentacam corneal analysis system. ●RESULTS:
Six months after operation, the FS-LASlK posterior corneal surface height was 6. 47 ± 1. 65mm, significantly higher than 5. 20 ± 1. 32mm before operation. SMlLE posterior corneal surface height was 6. 40 ± 1. 33mm, significantly higher than 5. 18 ± 1. 25mm before operation, the differences were statistically significant( P0. 05). ●CONCLUSION:
After FS-LASlK and SMlLE, the corneal posterior surface is protrusive. FS - LASlK is slightly obvious than SMlLE in early period. The stability of the posterior surface is better after SMlLE.
