[Anterior chamber intraocular lenses for aphakia correction]

Area of Science:

• Ophthalmology
• Biomedical Engineering

Context:

• Aphakia correction is crucial for visual rehabilitation.
• Anterior chamber intraocular lenses (IOLs) are commonly used.
• Existing IOLs present long-term complication risks.

Purpose:

• To review current anterior chamber intraocular lens (IOL) options for aphakia correction.
• To discuss the limitations and complications associated with these IOLs.
• To introduce alternative IOL fixation methods.

Summary:

• The primary methods for anterior chamber aphakia correction involve angle supported (e.g., Kelman Multiflex) and iris fixated (e.g., Artisan/Verisyse) intraocular lenses (IOLs).
• While offering acceptable outcomes, both IOL types have documented long-term complications in some patients.
• Alternative strategies include retropupillary Artisan and sclera fixated IOLs.

Impact:

• Highlights the need for safer and more durable aphakia correction methods.
• Informs ophthalmologists about the risks and benefits of different IOLs.
• Guides the development of next-generation intraocular lenses.
