No results posted yet for this study

Summary

The aim of our study is to analysis and compare the relationship between ORA and postoperative astigmatism in low astigmatism (less than 1D) and moderate to high (1D to 3D) astigmatism patients after SMILE (Small Incision Lenticule Extraction) refractive surgery.

Conditions

  • Refractive Errors
  • Astigmatism

Interventions

PROCEDURE

Small Incision Lenticule Extraction

A 500 kHzVisumax (Carl Zeiss Meditec AG) femtosecond laser was used with cap thickness ranging from 100 to 130μm, cap diameter from 7.3 to 7.9 mm. The lenticule was dissected with a blunt spatula through a 30 to 60-degree incision at the 10 o'clock position and removed using forceps afterward. Treatment targets of both eyes were set to emmetropia, the refraction corrections were based on manifest refractions
