Visual Outcomes And Satisfaction After Bilateral Edof, Bifocal, And Mix-And-Match Iol Implantation In A Chinese Population In The Digital Age

To evaluate and compare the visual outcomes of three intraocular lens (IOL) implantation strategies—bilateral extended depth of field (EDOF) IOL, bilateral bifocal IOL, and a mix-and-match approach—among patients in a Chinese population within the context of the modern digital age. 

Fuzhou University Affiliated Provincial Hospital, Fuzhou, China.

Patients with bilateral age-related cataracts selected their preferred IOL implantation type and were categorized into three groups accordingly. Three months after surgery, assessments of corrected and uncorrected binocular visual acuity at far, intermediate, and near distances were conducted, along with evaluations of refraction, defocus curve, stereoacuity, subjective visual quality, photic symptoms and difficulties in using digital device. 

Of the 76 patients (152 eyes) included, visual acuity at all distances was significantly improved across all groups. The bifocal IOL group demonstrated inferior best-corrected and uncorrected intermediate visual acuity (both P<0.001), while the EDOF IOL group exhibited lower best-corrected distance visual acuity (P=0.020) compared to the other two groups. All groups reported similar outcomes in stereoacuity, subjective visual quality, photic symptoms, and difficulties using digital devices.

Bilateral implantation of the three IOL strategies provided satisfactory visual results and effectively met the visual demands of a digital lifestyle.
