Presbyopia Correction in Lens Replacement Surgery: A Review

Area of Science:

• Ophthalmology
• Biomedical Engineering
• Vision Science

Background:

• Presbyopia affects 1.8 billion globally, increasing with life expectancy and near-vision tasks.
• Cataract surgery presents an opportunity to address presbyopia, reducing reliance on corrective lenses.
• Growing near-vision demands, especially from mobile device usage, exacerbate presbyopia challenges.

Purpose of the Study:

• To review current intraocular lens (IOL) technologies for presbyopia correction.
• To outline surgical strategies for managing presbyopia during lens replacement.
• To emphasize personalized patient selection for optimal visual outcomes.

Main Methods:

• Review of current literature on presbyopia-correcting IOLs.
• Analysis of surgical techniques for IOL implantation.
• Discussion of patient-specific factors influencing IOL choice.

Main Results:

• Partial correction (monovision, extended depth-of-focus IOLs) improves intermediate vision with trade-offs.
• Multifocal IOLs are most effective for complete presbyopia correction.
• Mix-and-match and supplementary IOLs offer flexible solutions, including reversibility.

Conclusions:

• Personalized IOL selection is crucial, considering visual needs and ocular anatomy.
• Advanced IOL technologies provide options for presbyopia correction during cataract surgery.
• Careful consideration is needed for patients with complex ocular conditions.
