Comparison of flange creation in three-piece intraocular lenses between high- and low-temperature cautery.

ABSTRACT:

Background

To compare flange creation using high- vs. low-temperature cautery for three piece intraocular lenses (IOLs) with PMMA and PVDF haptics.

Methods

The ends of the haptics from ten three-piece IOLs with PMMA haptics (AR40, Johnson & Johnson, USA) and ten three-piece IOLs with PVDF haptics (PU6AS, KOWA, Japan) were each heated for 1 mm to form a flange-using low-temperature cautery (593 °C) on the ipsilateral haptic and high-temperature cautery (1205 °C) on the contralateral haptic. Flange size, shape, and formation time were analysed.

Results

There were no differences in flange shape and flange size between high- and low-temperature cautery for each haptic type (p > 0.05). Average flange size of the AR40 IOL and the PU6AS IOL were 422 ± 22 μm and 363 ± 14 μm,
