Purpose
To compare the clinical and patient-reported outcomes in patients implanted with two modalities of trifocal intraocular lenses (IOLs) regarding distance and near contrast sensitivity and the patient-reported qualioty of vision.
Setting
Randomized Clincal Trial
Methods
Randomised clinical trial enrolling 60 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)
- RayOne (Rayner Intraocular Lenses, Ltd.,Worthing, UK) (Group RO, 30 eyes
All patients were recluted from the Department of Ophthalmology, Vithas Medimar International Hospital, Alicante, Spain
Visual acuity, distance (CSV-1000) and near contrast sensitivity (CS) (OpticTrain), and perception of visual disturbances (QoV questionnaire) were evaluated at 1 month after surgery.
Results
No significant differences were found between groups in postoperative binocular uncorrected distance (p=0.645), intermediate (p=0.803) and near visual acuity (p=0.645)
Regarding binocular distance contrast sensitivity (CS), significantly better values were found for the spatial frequency of 6 cycles/º in RO group (1.7±0.2 vs. 1.9±0.3, p=0.010)
In contrast, no significant differences were found between groups in near CS (p≥0.341)
A non-statistically significant trend was found in RO group to obtain lower Rasch-calibrated scores of the QoV questionnaire compared to FV group in terms of frequency (p=0.325), severity (p=0.117) and bothersomeness (p=0.303) of photic phenomena.
Conclusions
The two trifocal IOLs evaluated in the current study are effective for a distance, intermediate and near visual function.
The RayOne IOL provides better distance visual quality, with a trend to minor impact of photic phenomena
