Abstract Details


To evaluate the clinical outcomes with the AT LISA tri (Carl Zeiss Meditec, Jena, Germany) trifocal intraocular lens (IOL).


Optegra Yorkshire Eye Hospital, Yorkshire, UK


Observational case series. Twenty-five patients (50 eyes) underwent cataract or lens replacement surgery with implantation of the AT LISA trifocal IOL (either the tri 839MP spherical IOL (N=43, 86%), or the tri 939MP toric IOL (N=7, 14%)). All procedures were carried out by a single surgeon. Pre- and post-operative monocular uncorrected distance (UDVA), intermediate (UIVA) and near (UNVA) visual acuity, corrected distance visual acuity (CDVA), manifest refraction and operative and post-operative complications were recorded.


The mean age of the patients was 58 ± 8 years (ranging from 44 to 74 years). Follow-up visits took place, on average, 37 ± 41 days after surgery (range 7 to 196 days). Mean monocular UDVA was 0.53 ± 0.37 logMAR pre-operatively and 0.00 ± 0.11 logMAR, post-operatively (P<0.01). Post-operative spherical equivalent refractive error was within ±1.0 D in 100% of eyes and within ±0.5 D in 84% of eyes. 93% of eyes read N6 or better unaided. Binocular data for UNVA revealed that 96% of patients read N6 or better. For unaided intermediate vision, 74% of eyes achieved N12 or better monocularly and 95% of patients achieved N12 binocularly. Monocularly 63% of eyes achieved UDVA 20/20 and UNVA N6 in combination. Binocularly 96% of patients achieved UDVA 20/20 and UNVA N6 in combination. No operative complications and no post-operative complications were recorded.


The AT LISA trifocal IOL proved to be a safe and effective way to enhance distance, intermediate and near vision in this cohort of patients. FINANCIAL INTEREST: NONE
