Purpose
To compare the clinical outcomes between PRECIZON GO enhanced monofocal and PRECIZON Monofocal intraocular lenses (IOLs) in patients undergoing cataract surgery, with the primary objective being the difference in binocular corrected and uncorrected intermediate visual acuity at 66 cm (UIVA), Contrast sensitivity and defocus curves were evaluated.
Setting
Prospective Randomised study. Part of a multi centric study
Methods
This study included 24 patients (48 eyes) who underwent bilateral cataract surgery. Patients were randomly assigned to receive either PRECIZON GO (n=12) or PRECIZON Monofocal (n=12) IOLs. At 3-month postoperative assessments included refraction, monocular and binocular Uncorrected and Corrected Distance Visual Acuity (UDVA, CDVA), Uncorrected and Distance-Corrected Intermediate Visual Acuity (UIVA, DCIVA), binocular contrast sensitivity, and monocular defocus curves.
Results
At 3 months postoperatively, Uncorrected binocular Intermediate Visual Acuity (UIVA) was statistically better in the PRECIZON GO group (0.16 ± 0.15 logMAR vs. 0.33 ± 0.15 logMAR, p=0.002). No significant difference was observed for distance visual acuity (UDVA) and (CDVA). Defocus curves revealed better intermediate vision in the PRECIZON GO group, particularly between -2.00 D and -4.00 D (p = 0.0359), as well as for the +0.50 D value (p= 0.0496).Additionally, contrast sensitivity was significantly higher in the PRECIZON GO, indicating enhanced contrast perception at various visual resolutions.
Conclusions
Both IOLs provided excellent distance vision, but PRECIZON GO significantly improved intermediate visual acuity and contrast sensitivity, offering functional advantages for patients. Further studies are needed to evaluate long-term outcomes, particularly in terms of contrast sensitivity and defocus performance.
