Purpose
To compare the patient reported visual outcomes of the first hydrophobic acrylic refractive trifocal intraocular lens (IOL) (LuxLife IOL, study group - (Bausch + Lomb)), with that of its monofocal parent IOL (LuxGood IOL, control group - (Bausch + Lomb)) in patients undergoing bilateral cataract surgery.
Setting
Seven clinical centers in Spain and Czech Republic.
Methods
A multicenter, prospective, open-label study that included cataract patients, aged 50 years or older with no ocular comorbidity, and maximum preoperative corneal astigmatism of 1.0 D, assigned (2:1), with bilateral implantation with LuxLife or LuxGood IOLs. Patients were followed up through 4-6 months. Outcome measures included binocular CDVA (in logMAR), visual symptoms evaluated with CatQuest-9SF, Patient-Reported Spectacle Independence Questionnaire (PRSIQ), and binocular defocus curve.
Results
170 patients were included: 115 in the study group (mean age: 68±6.9) and 55 in the control group (mean age: 73±6). After 4-6 months, binocular CDVA was -0.01±0.07 and -0.08±0.06, respectively. According to PRSIQ, 81% vs 13%, respectively were spectacle-free at all distances. Patients reported no difficulties in reading newspapers (83% vs 47%; p<0.001), reading price tags while shopping (84% vs 53%; p=0.001), and for handicraft and woodwork activities, etc (79% vs 61%; p=0.168) in the study and control groups respectively. Binocular defocus curve showed an extended range of vision at a level of 0.2 CDVA of 3.25 D and 1.5 D respectively. No statistical difference between both groups regarding halo but the study group perceived larger glare.
Conclusions
Following bilateral implantation, more patients implanted with the LuxLife IOL were spectacle-free and less challenged in intermediate and near vision, in comparison to those implanted with the LuxGood IOL. The optical design of LuxLife IOL was found to provide good visual quality within an acceptable range of distances due to a large amplitude of pseudoaccomodation within an acceptable range of distances without being restricted by photic phenomena.
