Purpose
To compare the near contrast sensitivity outcomes in patients implanted with two modalities of trifocal intraocular lenses (IOLs).
Setting
Department of Ophthalmology. Vithas Medimar International Hospital, Alicante, Spain
Methods
Randomised clinical trial enrolling 40 subjects (age, 47-75 years) undergoing cataract surgery with implantation of one of two trifocal diffractive IOLs: Finevision POD F (PhysIOL, Liège, Belgium) (Group FV, 30 eyes) and RayOne (Rayner Intraocular Lenses, Ltd.,Worthing, UK) (Group RO, 30 eyes). Near (40 cm) achromatic contrast sensitivity (CS) was evaluated at 3 months after surgery using the previously validated OptoPad CSF system (University of Alicante), the OpticTrain system (Proconsi, Leon, Spain) and the Pelli Robson test.
Results
No significant differences were found between groups in the logMAR visual acuities measured in the defocus curve (p≥0.159), except for the value corresponding to the defocus level of -1.5 D (FV 0.08±0.06 vs. RO 0.00±0.05, p=0.021). Regarding achromatic near CS measured with OptoPad (spatial frequencies from 1.5 to 24 cycles/º), no significant differences were found between IOL groups (p≥0.053). No significant differences were found either bettween IOL groups in CS values measured with OpticTrain (spatial frequencies from 0.5 to 6 cycles/º using Gabor patches) (p≥0.30). Likewise, no significant differences were found in near logMAR CS value measured with the Pelli-Robson test (FV 1.70±0.17 vs. RO 1.76±0.12, p=0.245).
Conclusions
The two trifocal IOLs evaluated in the current study provides good achromatic CS outcomes at near, with no significant differences between them. Differences between the two IOLs evaluated in intermediate visual quality should be investigated further.
