AcrySof intraocular lenses (IOLs) can develop scratches during implantation. While these marks did not impact vision in this study, proper folding techniques are crucial to prevent damage.

Area of Science:

  • Ophthalmology
  • Biomaterials Science

Background:

  • Cataract surgery frequently involves the implantation of intraocular lenses (IOLs).
  • AcrySof IOLs are a common type of foldable IOL used in modern cataract surgery.

Purpose of the Study:

  • To investigate the incidence and origins of scratches and marks on AcrySof IOLs.
  • To assess the clinical significance of these IOL alterations.

Main Methods:

  • A clinical study involved implanting AcrySof IOLs in four eyes using McDonald-Livernois forceps.
  • An experimental study examined 50 sterile AcrySof IOLs folded with modified Steinert or Buratto forceps under surgical microscopy.

Main Results:

  • Three of the four clinically implanted IOLs exhibited scratches or marks, which did not necessitate explantation or affect visual recovery.

  • Microscopic examination revealed defects in 32 of 50 folded IOLs, with alterations ranging from minimal to multiple per lens.

    • Conclusions:

    • AcrySof IOLs demonstrate greater fragility compared to silicone IOLs.
    • Specific folding techniques, including folding along the 6 to 12 o'clock axis and sequential haptic insertion, are recommended to minimize IOL damage.
