Summary
Using the wrong forceps to fold intraocular lenses (IOLs) can damage acrylic IOLs. This study found that acrylic IOLs folded with silicone IOL forceps showed significant optic damage.
Area of Science:
- Ophthalmology
- Biomaterials Science
- Surgical Instrumentation
Background:
- Foldable intraocular lenses (IOLs) are commonly used in cataract surgery.
- Proper handling and folding techniques are crucial to prevent IOL damage.
- Specific forceps are designed for silicone and acrylic IOLs due to material differences.
Purpose of the Study:
- To investigate potential damage to foldable silicone and acrylic intraocular lenses (IOLs) when incorrect lens folding forceps are used.
- To assess the impact of using mismatched forceps on IOL optic integrity.
Main Methods:
- Ten silicone and ten acrylic IOLs were used, divided into two groups.
- Group 1: Lenses folded with correct, material-specific forceps.
- Group 2: Silicone IOLs folded with acrylic forceps, and acrylic IOLs folded with silicone forceps. Lens damage was assessed using transmission and scanning electron microscopy.
Main Results:
- Acrylic IOLs folded using forceps intended for silicone IOLs exhibited significant damage to the lens optic.
- Silicone IOLs folded with acrylic forceps did not show comparable damage (implied, as only acrylic damage was reported).
Conclusions:
- The use of incorrect folder forceps poses a risk of damaging acrylic intraocular lenses.
- Material-specific forceps are essential for safe and effective IOL folding during cataract surgery.
