Size variability and fitting of 30 gauge thin-wall needles and 3-piece intraocular lens haptics for flanged intrascleral fixation technique.

Most of the analysed haptics would fit into most of the measured needles, with the exception of the Sensar AR40 in combination with the Meso-relle or Sterimedix needles. The combination of a larger needle lumen and a thinner haptic could result in more ease of insertion during surgery. If the dimensions of the needle and IOL haptics used are unknown, we recommend trying insertion before beginning surgery.
