Abstract Details

Purpose:

To test the refractive and visual outcomes and the quality of vision (frequency and severity of dysphotopic phenomena, spectacle use and overall satisfaction) after the bilateral implantation of three different multifocal intraocular lenses (MIOLs) in patients with age-related cataract.

Setting:

Dnipropetrovsk Regional Clinical Ophthalmological Hospital, Ukraine.

Methods:

In this prospective, comparative study including 90 eyes of 45 cataract patients, bilateral implantation of either the hydrophilic trifocal Liberty® 677MY capsular bag IOL by Medicontur Ltd, the hydrophilic AT LISA® tri 839M lens (Carl Zeiss Meditec AG), or the hydrophobic AcrySof® IQ PanOptix® IOL (Alcon Inc.) was performed during routine cataract surgery. Refractive outcomes, visual acuities (VA) for far (5.0 m), intermediate (0.8, 0.6 m) and near (0.4 and 0.3 m) distances, and visual acuity curves were assessed three months postoperatively. Visual quality, dysphotopic events and spectacle use were evaluated using McAlinden’s questionnaire during the 3-month postoperative visit.

Results:

VA curves were similar for the three MIOLs, however the Liberty lens seems to be superior for far and near, while AT LISA tri provides somewhat better VA in the intermediate range (60 cm). Refractive correction was the most effective with the Liberty IOL (p=0.0131). Dysphotopic phenomena (glare, halo) were usually perceived at night or in low light conditions. Their frequency was lower with AT LISA tri and Liberty lenses, however the severity of dysphotopic events were the lowest with the Liberty IOL. Two-third of AT LISA tri and Liberty patients, while only 57% of PanOptix patients achieved spectacle independence.

Conclusions:

Our investigation revealed that all three examined MIOLs are safe and efficient in presbyopia-correction of cataract patients, however different models have different capacities in restoring far, intermediate or near vision. The correction of refractive errors was the most effective with the Liberty IOL, and dysphotopic symptoms were significantly less disturbing for patients implanted with the Liberty lens. We conclude that the vision preferences of each patient should be always taken into consideration when choosing a MIOL, and the possible occurrence of dysphotopic events should be also clearly communicated in each case.
