Comparison of Two Presbyopia-Correcting Trifocal Intraocular Lenses: A Prospective Study

Area of Science:

• Ophthalmology
• Biomedical Engineering
• Optics

Background:

• Cataract surgery is a common procedure to restore vision.
• Trifocal intraocular lenses (IOLs) offer improved visual function by providing clear vision at multiple distances.
• Evaluating new IOL designs is crucial for enhancing patient outcomes.

Purpose of the Study:

• To compare the clinical results of a novel sinusoidal trifocal IOL (Acriva Trinova) with a traditional trifocal IOL (Acrysof IQ PanOptix).
• To assess visual acuity, contrast sensitivity, patient satisfaction, and photic phenomena after bilateral IOL implantation.

Main Methods:

• Prospective study involving 79 patients undergoing cataract surgery with bilateral implantation of either Acriva Trinova or Acrysof IQ PanOptix IOLs.
• Evaluated visual and refractive outcomes, contrast sensitivity, and defocus curves at 3 months post-surgery.
• Assessed patient satisfaction and incidence of photic phenomena.

Main Results:

• No significant differences in distance, intermediate (60 cm), or near visual acuities between the two IOL groups.
• The Acriva Trinova group demonstrated significantly better intermediate visual acuity at 80 cm (p<0.05).
• Both IOLs provided good contrast sensitivity and a wide range of intermediate vision; patient recommendation rates were high for both.

Conclusions:

• Both the Acriva Trinova and Acrysof IQ PanOptix trifocal IOLs deliver satisfactory visual quality and high patient satisfaction.
• The Acriva Trinova IOL may offer an advantage in specific intermediate visual tasks.
