Visual Results After Extended Depth-of-Focus Lens Implantation in Patients Undergoing Clear Lens Surgery

Area of Science:

• Ophthalmology
• Refractive Surgery
• Intraocular Lenses

Background:

• Presbyopia correction is a growing area in refractive surgery.
• Extended depth-of-focus intraocular lenses (IOLs) aim to provide a broad range of vision.
• Refractive lens exchange (RLE) is an option for presbyopia correction in non-cataract patients.

Purpose of the Study:

• To evaluate the efficacy and visual quality of the AcrySof IQ Vivity extended depth-of-focus IOL.
• To assess patient satisfaction and visual disturbances after RLE for presbyopia.

Main Methods:

• Prospective, single-arm clinical study.
• 30 patients (60 eyes) aged 49-69 years underwent RLE with the Vivity IOL.
• Postoperative visual acuity (distance, intermediate, near) and patient-reported outcomes were assessed at 3 months.

Main Results:

• Excellent uncorrected visual acuity achieved: distance (0.00 logMAR), intermediate (0.08 logMAR), and near (0.18 logMAR).
• High patient satisfaction (93.2%) with 63.3% achieving spectacle independence.
• Mild photic phenomena reported: 23% halos, 30% glare.

Conclusions:

• The Vivity IOL provides excellent far and intermediate vision with functional near vision in photopic conditions.
• High patient satisfaction and minimal visual disturbances were observed.
• This IOL is a promising option for RLE in presbyopic patients without cataracts.
