Refractive and Visual Outcomes of New Segmented Bifocal IOL
Narrative Responses:
Purpose
To evaluate effectiveness, safety and patient satisfaction with the Lenstec SBL-3 segmented bifocal lens
Methods
This study comprised 50 presbyopic patients who had implantation of a Lenstec SBL-3 multifocal IOL after phacoemulsification. The mean age of the study group was 55.6 ± 6.1 years and the mean preoperative spherical equivalent refraction was +2.87 ± 1.9 D. The main outcome measures were refraction, uncorrected (UDVA) and corrected (CDVA) distance visual acuities, uncorrected intermediate visual acuity at 70 cm (UIVA), uncorrected (UNVA) and corrected (CNVA) near visual acuities at 40 cm and patient satisfaction.
Results
At three months, the mean postoperative sphere was +0.09 ± 0.22 D and the mean cylinder -0.29 ± 0.12 D. The mean postoperative UDVA and CDVA were -0.01 ± 0.09 logMAR and -0.09 ± 0.11 logMAR, respectively. Patients achieved the mean binocular UIVA of 0.15 ± 0.18 logMAR and the mean binocular UNVA of 0.11 ± 0.08 logMAR. Moderate glare and halos were reported by 6.0% of patients.
Conclusion
Initial results indicated that this new segmented bifocal lens provides good uncorrected distance, intermediate and near vision.
