Clinical Outcomes Of Mini-Monovision Using A New Monofocal Intraocular Lens (Tecnis® Eyhance) : Visual Acuity, Defocus Curve, Contrast Sensitivity, Spectacle Independence, And Patient Satisfaction

Modified monovision—or “mini-monovision”—is an alternative method to multifocal intraocular lenses (IOLs) for treating presbyopia. The achievement of blended vision using monofocal IOLs minimizes the photic phenomena associated with multifocal IOLs and broadens patient eligibility. This study aimed to evaluate the clinical outcomes of patients bilaterally implanted with the new enhanced monofocal Tecnis® Eyhance (ICB00) IOLs with the mini-monovision technique to improve near vision.

Severance Eye Hospital, Yonsei University College of Medicine, Seoul, South Korea.

In this retrospective case series, the medical records of 50 patients (100 eyes) who underwent immediately sequential bilateral femtosecond laser-assisted cataract surgery (FLACS) using the Eyhance IOL were reviewed. Patients were divided into the Emmetropia and Mini-monovision groups based on the postoperative spherical equivalent and residual myopia. The binocular visual acuity for far (4 m), intermediate (66 cm), and near (40 cm) distances, binocular defocus curves, contrast sensitivity, visual symptoms, spectacle independence, and patient satisfaction rates were evaluated at 3 months postoperatively.

The binocular uncorrected distance and intermediate visual acuities, contrast sensitivity, incidence of photic phenomena, and patient satisfaction were not significantly different between the two groups (p>0.05). However, the binocular uncorrected near visual acuities and spectacle independence rates were significantly better in the Mini-monovision group (p<0.05).

Conclusively, the pseudophakic mini-monovision technique using enhanced monofocal IOLs may be a promising option for presbyopia correction in patients unsuitable for multifocal IOLs. FINANCIAL DISCLOSURE: None.
