Mini-monovision versus multifocal intraocular lens implantation

Area of Science:

• Ophthalmology
• Refractive Surgery
• Cataract Surgery

Background:

• Senile cataract treatment involves visual correction options.
• Monovision and multifocal intraocular lenses (IOLs) are common surgical choices.
• Patient satisfaction and visual function are key outcomes.

Purpose of the Study:

• Compare monovision correction versus multifocal IOL implantation.
• Evaluate patient satisfaction, spectacle dependence, visual acuity, and dysphotopsia.
• Assess outcomes in cataract patients post-surgery.

Main Methods:

• Prospective randomized trial involving 75 cataract patients.
• Patients assigned to monovision or multifocal IOL groups.
• Assessed uncorrected/corrected distance visual acuity (UDVA/CDVA), VF-14, and spectacle dependence pre- and post-surgery.

Main Results:

• Both techniques yielded excellent refractive outcomes (UDVA, VF-14).
• No significant difference in VF-14 scores between groups.
• Monovision group had increased near spectacle dependence but less glare.

Conclusions:

• Monovision and multifocal IOLs provide excellent distance vision.
• Multifocal IOLs reduce overall spectacle dependence.
• Multifocal IOLs are associated with significantly more dysphotopsia.
