Visual function and patient satisfaction: Comparison between bilateral diffractive multifocal intraocular lenses and...

Area of Science:

• Ophthalmology
• Vision Science
• Biomedical Engineering

Background:

• Cataract surgery often involves intraocular lens (IOL) implantation to restore vision.
• Multifocal IOLs and monovision strategies using monofocal IOLs are common approaches to achieve spectacle independence.
• Patient satisfaction and visual function are key outcomes in evaluating IOL efficacy.

Purpose of the Study:

• To compare visual function and patient satisfaction between bilateral diffractive multifocal IOLs and monofocal IOL monovision.
• To assess outcomes such as visual acuities, stereo vision, spectacle independence, and subjective visual symptoms.

Main Methods:

• A cohort study involving 21 patients with bilateral multifocal IOLs and 22 patients with monofocal IOL monovision.
• Postoperative analysis at 3 months included binocular visual acuities (distance, intermediate, near), stereo vision, spectacle independence, and patient satisfaction.
• The Visual Function Questionnaire-25 was administered pre- and postoperatively.

Main Results:

• No statistically significant difference in distance or near visual acuity between the groups.
• Monovision group demonstrated significantly better intermediate vision and less computer use difficulty.
• Monovision patients reported higher overall satisfaction, fewer complaints, and lower out-of-pocket costs.

Conclusions:

• Pseudophakic monovision provides distance and near vision comparable to multifocal IOLs.
• Monovision avoids the visual disturbances associated with multifocal IOLs.
• Monovision offers superior intermediate vision and computer usability, with greater patient satisfaction.
