Abstract Details

Purpose:

To evaluate visual acuity, defocus curve, contrast sensitivity and patient satisfaction after implantation of an extended depth of focus (EDOF) IOL (Amo Tecnis Symfony) compared to a monofocal IOL.

Setting:

Ophthalmology Unit, department of Neurosciences, University of Verona, Verona Italy and Carones Ophthalmology Center, Milan, Italy

Methods:

90 eyes of 45 patients (group 1) affected by senile cataract undergoing bilateral phacoemulsification and implanted with EDOF IOL were enrolled. All patients were evaluated 3 months postoperatively for uncorrected (UDVA) and corrected distance visual acuity (BCDVA); uncorrected (UNVA) and corrected near visual acuity (BCNVA) at 40 cm, uncorrected (UIVA) and corrected intermediate visual acuity (CIVA) at 60 and 70 cm. Contrast sensitivity, defocus curve and patient satisfaction (NEI RQL-42) were also assessed. Aberrometry and OQAS were performed. Ggroup 1 was compared with a control group of 30 eyes (group 2) implanted with a monofocal IOL (Tecnis ZCBOO).

Results:

Both groups achieved an excellent UDVA and BCDVA. The EDOF IOL performed better in terms of UIVA and UNVA compared with monofocal IOL (p<0,05). An addition of 1,1D in group 1 and 2,75D in group 2 seems to be necessary to achieve an optimal near vision acuity (P<0,01). The EDOF IOL group achieved a good visual quality in terms of CS, RMS, MTF and Strehl Ratio without statistically significant difference compared to the monofocal IOL group but higher patient satisfaction with a low amount of subjective symptoms. Defocus curve in group 1 showed good spectacle independence with VA better than 0,4 up to -3D.

Conclusions:

according to our results, the EDOF IOL could be considered a good option in routine cataract surgery for patients willing a good visual acuity at all distances and high spectacle independence, without compromising quality of vision.
