Purpose:
To demonstrate the novel use of a 31-gauge needle for flanged intrascleral intraocular lens (IOL) fixation using the double-needle technique.
Methods:
Flanged intrascleral IOL fixation was performed using the ZELOSTAT 31G (ASTI, Shizuoka, Japan) needle in a 73-year-old male with right IOL subluxation.
Results:
The IOL was successfully fixated with smooth intraoperative handling, excellent postoperative outcomes, no complications, and minimal refractive error.
Conclusion:
The 31-gauge needle has a larger inner diameter compared to the conventional 30-gauge thin-wall needle, which may facilitate intrascleral IOL fixation procedures.
