Abstract Details

Purpose:

To evaluate visual outcomes and patient satisfaction of bilateral implantation of EDoF IOL, AT LARA 829 MP, a 12 months follow-up.

Setting:

Single-center retrospective study

Methods:

The surgery was performed using a microincision phacoemulsification technique.The inclusion criteria were patients with visually significant bilateral cataract, expectation on glasses independence but accepting their use for near activities and at least 12 months of follow-up.Patients with any ocular disorders or previous surgery, corneal astigmatism over 1.00D or axial length within the extreme range (<21.5mm or >25.5mm) were excluded. The AT LARA 829 MP was implanted bilaterally in 20 patients (7 men and 13 women) with a mean age of 70.9 years old. Main outcomes were visual acuity at distance, intermediate (70cm) and near (40cm), defocus curve and patient’s satisfaction.

Results:

The mean spherical equivalent after surgery was −0.30 ± 0.27 diopters (D). Binocular visual acuities (VA) were: Uncorrected Distance VA 0.17 ± 0.36  logMAR (20/30); Corrected Distance VA 0.03 ± 0.05 logMAR (20/21); Uncorrected Intermediate VA 0.21 ± 0.12 logMAR (20/32); Uncorrected Near NVA 0.25 ± 0.16 logMAR (20/35). The defocus curve confirmed good VA also in the intermediate distance with 90% of the patients presenting VA higher than 20/40 for a defocus curve between +0.5 D and -1.5 D. Patient satisfaction was high, more than 85 % of the patients satisfied with their intermediate and distance vision.

Conclusions:

Activities requiring intermediate vision are of great importance in the daily life of our modern society. This enhanced depth of focus (EDoF) IOLs based on a diffractive optical pattern is indicated for patients whose main focus are distance and intermediate vision. After 12 months of follow-up, the level of satisfaction is still high with good visual outcomes and high spectacle independence. Only 5% of the patients presented visual complaints, representing a reduction when compared to the first evaluation at 3 months postoperatively.
