Purpose

To evaluate post-operative visual outcomes of enhanced monofocal IOL (XY1-EM with central 2mm nano-thin optical elements with smooth surface profiling) - in terms of distant, intermediate, and near visual acuities, refractive outcomes, contrast sensitivity, objective ocular optical quality, in addition to patient experiences.

Setting

 A Single-center, nonrandomized, ambidirectional cohort.

Methods

A Single-center, nonrandomized, ambidirectional cohort, from the records of adult patients who underwent uneventful sequential bilateral implantation of enhanced monofocal IOL (XY1-EM with central 2-mm nano-thin optical elements with smooth surface profiling), was postoperatively evaluated prospectively for visual performances, including defocus functions, aberrometry, contrast sensitivity (FACT sine wave tests), and objective evaluation of the ocular optical quality in addition to patient-reported outcomes for intermediate vision and NEI-VFQ25. The study included 136 eyes from 68 subjects.

Results

The Mean UCVA-distance was 0.03+/-0.01 Log MAR, UCVA-Intermediate (Defocus at 1.5D) was 0.13+/- 0.02, and UCVA for near was 0.35+/- 0.16. HOAs at mesopic conditions (5 mm pupil) were 0.22+/- 0.09 mic. The Mean of contrast sensitivity functions at 3,6,12,18 CPD were 1.76,1.98,1.63,1.23 Log CS under photopic conditions, & 1.71,1.94,1.61,1.21 Log CS under mesopic conditions, respectively. Over 86% of study subjects reported good driving comforts, and 92% subjects reported good uncorrected intermediate vision. The vision targeted composite score
 was 94% amongst subjects in the cohort.

Conclusion

XY1-EM Enhanced monofocal IOL showed excellent distance, intermediate visual outcomes, aberrometry, and photic phenomena perception. They represent an interesting option in the standard treatment of cataracts because they provide good spectacle independence for intermediate distances, while preserving excellent performance for distance vision.
