Opacification of Array SA40N silicone multifocal intraocular lens

Area of Science:

• Ophthalmology
• Biomaterials Science

Background:

• Intraocular lenses (IOLs) are crucial for vision restoration after cataract surgery.
• Multifocal IOLs offer improved near and distance vision but can have unique complications.

Observation:

• Two cases of multifocal intraocular lens (IOL) opacification were identified.
• Opacification can affect the optical clarity and performance of the IOL.

Findings:

• Multifocal IOLs demonstrated opacification, a clouding of the lens material.
• This opacification may necessitate explantation, the removal of the IOL.

Implications:

• The findings suggest a potential increased risk of explantation for multifocal IOLs compared to monofocal IOLs.
• Further research is needed to understand the mechanisms and prevalence of IOL opacification.
