Clear lens extraction with multifocal apodized diffractive intraocular lens implantation

Area of Science:

• Ophthalmology
• Refractive Surgery

Background:

• Clear lens extraction (CLE) is an alternative to cataract surgery for refractive error correction.
• Multifocal intraocular lenses (IOLs) aim to restore both distance and near vision.

Purpose of the Study:

• To evaluate the efficacy, safety, predictability, and stability of CLE with AcrySof ReSTOR multifocal IOLs.
• To compare outcomes between myopic and hyperopic patients.

Main Methods:

• Prospective, nonrandomized, observational case series involving 112 patients (224 eyes).
• Patients underwent bilateral CLE with AcrySof ReSTOR Natural IOLs.
• Visual acuity and refractive outcomes were assessed preoperatively and 6 months postoperatively.

Main Results:

• 100% of eyes achieved uncorrected distance visual acuity of 20/25 or better.
• High efficacy and safety indexes were observed for both myopic and hyperopic groups at distance.
• Hyperopic patients demonstrated superior uncorrected near visual acuity and higher near efficacy indexes compared to myopic patients.

Conclusions:

• CLE with multifocal IOL implantation effectively corrects ametropia and presbyopia.
• The procedure demonstrates comparable safety and efficacy for distance vision in both myopic and hyperopic eyes.
• Hyperopic patients experienced enhanced near vision outcomes following multifocal IOL implantation.
