Visual Outcomes With Intraocular Trifocal Lens Implant

Area of Science:

• Ophthalmology
• Surgical Innovation
• Vision Science

Background:

• Cataract surgery is a leading global procedure, with a projected 16% increase in the USA by 2024.
• Cataract extraction constitutes 25% of all surgical procedures worldwide.
• The study addresses the growing need for improved visual outcomes post-surgery.

Purpose of the Study:

• To analyze visual outcomes following intraocular lens implantation.
• To evaluate vision across distance, intermediate, and near visual ranges.
• To assess the efficacy of trifocal intraocular lenses.

Main Methods:

• Non-comparative interventional study conducted at Al Ehsan Eye Hospital (Jan-Dec 2021).
• Included patients undergoing uneventful phacoemulsification with intraocular lens implantation.
• Assessed uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), and uncorrected near visual acuity (UNVA).

Main Results:

• Significant improvement in distance vision (p<0.001) at 1 day, 1 week, and 1 month post-trifocal intraocular lens implantation.
• Mean visual acuity values: 0.3±0.1 (1 day), 0.17±0.09 (1 week), 0.14±0.08 (1 month).
• Mean improvement in near vision to N6 and intermediate vision to N8 after 1 month.

Conclusions:

• Trifocal intraocular lens implantation enhances vision across near, intermediate, and distant ranges.
• The procedure offers spectacle independence.
• Results indicate a significant improvement in uncorrected visual acuities.
