To evaluate the visual outcomes after trifocal IOL implantation, comparison between toric (tt) and non-toric IOL (ntt).
Breyer Kaymak Augenchirurgie, Internationale Innovative Ophthalmochirurgie
This retrospective study comprises results after bilateral implantation of either a nt IOL (40 eyes, 20 patients) or a tt IOL (either bilateral or monolateral, 10 eyes). Each eye was documented postoperatively seven days, binocular exams followed after 1, 3 month after surgery. Subjective refraction (SR), defocus curve (DC), contrast sensitivity (CS), halos & glare assessment (HGA) and a patient questionnaire were documented.
After surgery spherical equivalent resulted in -0.05 ±0.04 (non-toric) and average uncorrected far distance VA was 1.0 (decimal visus). Intermediate VA and near visual acuity was comparable between both IOL types (IV > 0.8 decimalvisus, NV > 0.63 decimalvisus). The respective defocus curve showed 2 peaks for near- & far distance VA. IV was represented by a pleateu instead of a peak at around 70 cm with a decimal visus of 0.9 ±0.1 (ntt IOL) and 0.8 ±0.2 (tt IOL). CS was very similar with both IOL types and was comparable to CS of phakic younger patients at certain spatial frequencies. Photopic phenomena like halos and glares were remarkably low reported in both IOL types.
Considering life style aspects of our patients in case of a computer-based daily routine, as well as menage, handcraft or excellent night vision, the trifocal lens accomplishes patients needs better compared to the former generation IOL including tricky light conditions, especially in „younger“ patients. All patients did conduct nocturnal car trips, but only the trifocal IOL population stated the absence of disturbing halos & glares. FINANCIAL INTEREST: NONE
