Abstract Details

Purpose:

To compare the outcomes at 3 months in terms of refraction, visual acuity, defocus curves and complications of the implantation of a novel trifocal IOL, a sinusoidal IOL, compared to 2 diffractive trifocal IOLs.

Setting:

Private refractive surgery clinic

Methods:

Retrospective case cohort comparison of all cases of bilateral implantation of a trifocal IOL for cataract surgery or refractive lens exchange, during 2018. In 58 eyes a hydrophilic plate haptics sinusoidal trifocal IOL (Trinova, VSY) were implanted (group A). In 26 eyes a hydrophobic diffractive non-apodized trifocal IOL (Panoptix, Alcon) (group B), and in 48 eyes a diffractive non-apodized hydrophilic trifocal IOL (AT LISA 839MP, Zeiss) (group C) were implanted. Outcome measures were refractive and visual outcomes, defocus curves and comparison, complication rate, and comparison of subjective refraction with autorefraction.

Results:

The mean postoperative UCDA was in group A, B and C was -0.05 + 0.05 logMAR, -0.02 + 0.05, and -0.03 + 0.11 respectively. The mean postoperative UCNA at patient preferred distance was logMAR 0.06 + 0.11, 0 + 0, and 0.01 + 0.02, respectively in groups A,B, and C. Complications occurred in 16/48 eyes with Trinova IOL, 1/26 eyes in the Panoptix group, and 1/48 eyes in the ATLISA 839MP group. Complications included inadequate near vision, capsular contraction syndrome, IOL exchange, and residual refractive errors. Automated refractions showed systematic more myopic results in eyes implanted with Trinova IOLs.

Conclusions:

Implantation with trifocal IOLs results in good uncorrected visual acuity. Differences between the IOLs are in the near visual function, halo perception, and complication rate (highest in the Trinova group). Predictability of IOL calculation was lowest with the Trinova IOL.
