Abstract Details

Purpose:

To assess distance, intermediate, and near visual outcomes in a large sample of patients who had bilateral implantation of the AT LISA tri 839 MP intraocular lens (IOL).

Setting:

Fernández-Vega Ophthalmological Institute, Oviedo, Spain.

Methods:

Two hundred and four eyes of 102 patients who underwent bilateral implantation of the AT LISA tri 839MP IOL following cataract surgery were assessed in the study. This IOL combines a central trifocal zone (+3.33 D and +1.66 D addition) with a bifocal diffractive pattern on the periphery. Monocular and binocular uncorrected (UDVA) and corrected distance visual acuity (CDVA), monocular and binocular uncorrected (UNVA) and distance-corrected near visual acuity (DCNVA), binocular uncorrected and distance-corrected intermediate visual acuity (DCIVA), the defocus curve, and binocular photopic and mesopic contrast sensitivity with and without glare were evaluated over 6 months.

Results:

There were no statistically significant differences in visual acuity outcomes between follow-up visits at any distance evaluated. Six months postoperatively, the mean monocular UDVA and UNVA were comparable to preoperative CDVA and DCNVA, respectively. All patients achieved a binocular CDVA of 20/25 or better. The mean binocular DCIVA ranged from 0.11±0.11 (70 cm) to 0.07±0.11 logMAR (50 cm). These visual outcomes were in accordance with the defocus curve, showing a wide range of useful vision. Mesopic contrast sensitivity was lower than under photopic conditions, particularly at medium and high spatial frequencies.

Conclusions:

Bilateral implantation of the AT LISA tri 839MP IOL provides good visual outcomes at far, intermediate, and near distances, being an effective solution to reduce spectacle dependence after cataract surgery.
