Abstract Details

Purpose:

To assess retinal measurements after trifocal intraocular lens (IOL) implantation using spectral-domain optical coherence tomography (OCT).

Setting:

Clínica Rementería, Madrid, Spain

Methods:

The study included patients having bilateral implantation of a monofocal IOL: AcrySof® IQ and a trifocal IOL: AcrySof® IQ PanOptixTM IOL. The monofocal group was considered as the control group of the study. The IOL power calculation was made in order to obtain emmetropia in all patients. Patients underwent basic OCT retinal measurements with the Cirrus HD-OCT®: mean average macular thickness, macular volume and retinal fiber nerve layer (RFNL) thickness. In all cases, OCT measurements were performed before and three months after the surgery.

Results:

The study analyzed 100 eyes of 100 patients (50 with monofocal and 50 with trifocal IOL). For the monofocal IOL, preoperative and postoperative values of the mean average macular thickness, macular volume and RNFL thickness were: 255.7 and 260.3 µm, respectively (p<0.001); 9.9 and 10.0 mm3 (p<0.001), respectively; 86.7 and 87.5 µm (p=0.14), respectively. For the trifocal IOL preoperative and postoperative values of the mean average macular thickness, macular volume and RNFL thickness were: 257.1 and 263.5 µm (p<0.001), respectively; 10.0 and 10.2 mm3 (p<0.001), respectively; 89.9 and 90.8 µm (p=0.07), respectively.

Conclusions:

Despite some statistical differences, the results of the present study suggest that the trifocal IOL under study does not induce an impact on spectral-domain OCT retinal measurements.
