Purpose
To investigate the postoperative functional outcomes and visual acuity of patients after bilateral implantation of the Zeiss AT ELANA 841P lens, a new hydrophobic trifocal intraocular lens (IOL).
Setting
Dept. of Ophthalmology, University of Heidelberg, Heidelberg, Germany
Methods
At our center, a total of 17 patients (64 ± 8 years) have undergone bilateral implantation of the AT ELANA 841P (Carl Zeiss Meditec AG, Jena, Germany) as cataract surgery or refractive lens exchange. Follow-ups are scheduled for 1 month, 3 months and 12 months and include: monocular and binocular uncorrected as well as distance corrected visual acuity for distance (UDVA, CDVA at 4m), intermediate (UIVA, DCIVA at 66cm and 80cm) and near (UNVA, DCNVA at 40cm), subjective refraction, monocular and binocular defocus curves, photopic and mesopic contrast sensitivity, patient satisfaction with regard to visual disturbances and spectacle independence as well as the evaluation of posterior capsule opacity.
Results
1-month post-surgery (n=16 patients), binocular visual acuity in logMAR was: UDVA/CDVA (-0.05/-0.13), UIVA/DCIVA at 80 cm (0.01/0.00), UIVA/DCIVA at 66 cm (-0.02/-0.01) and UNVA/CNVA at 40 cm (0.00/-0.03). At 3-month follow-up (n=10 patients), binocular visual acuity was UDVA/CDVA (-0.12/-0.16), UIVA/DCIVA at 80 cm (-0.02/-0.02), UIVA/DCIVA at 66 cm (-0.10/-0.07) and UNVA/CNVA at 40 cm (0.01/-0.03). Defocus curves showed a continuous visual acuity of 0.10 logMAR or better from +1.0 to -2.5D (1 month, binocular), +0.50 to -2.5D (3 months, monocular), and +1.0 to -3D (3 months, binocular). So far, the IOL shows good contrast sensitivity and high patient satisfaction. Further detailed evaluations are in progress.
Conclusions
Our initial results show that the AT ELANA 841P IOL provides a full spectrum of uncorrected vision over long distances and is a safe, predictable and effective treatment option for cataract or refractive lens exchange. Ongoing evaluation will provide further insights into photopic phenomena and contrast sensitivity and spectacle independence.
