Photopic and mesopic performance of 2 different trifocal diffractive intraocular lenses

Abstract

Purpose

To assess photopic and mesopic vision in patients implanted with 2 different trifocal intraocular lenses (IOLs).

Methods

Fifty patients with cataract in both eyes had surgery with bilateral implantation of a trifocal FineVision (FV, n = 25) or AT LISA tri 839MP (LisaTri, n = 25) IOL. Three months after surgery, high-contrast photopic uncorrected distance visual acuity and corrected distance visual acuity (CDVA) were determined using the Early Treatment Diabetic Retinopathy Study test. Intermediate (65 cm) and near (40 cm) visual acuity were also measured, both with best distance correction (DCIVA and DCNVA, respectively). The CSV1000 test chart was used for binocular and monocular contrast sensitivity. Defocus curves were constructed under photopic and mesopic conditions.

Results

Mean patient age was 68.4 ± 5.5 years (FV) and 67.3 ± 5.6 years (LisaTri) (p = 0.540). No differences were found in terms of visual acuity between the groups. The CDVA, DCIVA, and DCNVA were 0.05 ± 0.06, 0.25 ± 0.10, and 0.13 ± 0.10 logMAR for FV and -0.04 ± 0.11, 0.32 ± 0.09, and 0.12 ± 0.11 logMAR for LisaTri, respectively (p = 0.09, p = 0.08, and p = 0.12). Photopic and mesopic defocus curves were comparable between the 2 IOL groups (p>0.05). Mesopic values were significantly worse than photopic in both groups for all the measured values (p<0.001). No differences in contrast sensitivity were observed between the 2 IOL groups (p>0.05).

Conclusions

Both trifocal diffractive IOLs provided good visual quality with a statistically significant decrease in mesopic conditions.
