Abstract Details

Purpose:

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

Setting:

Optegra Yorkshire Eye Hospital, Yorkshire, UK

Methods:

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.

Results:

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.

Conclusions:

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
