Outcomes of a Refractive Segmented Bifocal Intraocular Lens with a Lower Near Addition
PURPOSE: To evaluate clinical and subjective outcomes of a segmented bifocal IOL with a 2.0 D near addition. PATIENTS AND METHODS: Retrospective analyses of patients who had undergone refractive lens exchange with bilateral implantation of the SBL-2 IOL (Lenstec, Inc., Christ Church, Barbados) were...

description | PURPOSE: To evaluate clinical and subjective outcomes of a segmented bifocal IOL with a 2.0 D near addition. PATIENTS AND METHODS: Retrospective analyses of patients who had undergone refractive lens exchange with bilateral implantation of the SBL-2 IOL (Lenstec, Inc., Christ Church, Barbados) were performed. The number of patients included in the study was 389 (778 eyes). Refractive, visual and patient-reported outcomes were presented for the last available visit (mean follow-up 2.05 ± 1.33 months). RESULTS: The percentage of eyes within ±0.50D and ±1.00D of emmetropia was 82.5% (642/778) and 97.8% (761/778), respectively. The mean uncorrected intermediate visual acuity (66 cm) of the last available visit was 0.08 ± 0.15 logMAR monocularly and 0.04 ± 0.14 logMAR binocularly. The mean monocular and binocular uncorrected near visual acuity (40 cm) were 0.30 ± 0.15 logMAR and 0.24 ± 0.14 logMAR, respectively. Of all patients, 97.2% (378/389) claimed never to use any correction for distance vision, while 93.1% (362/389) of patients did not require any correction for near vision. The mean scores for visual phenomena (on the scale from 1 – no difficulty to 7 – severe difficulty) were 1.8 ± 1.3, 1.7 ± 1.2, 1.7 ± 1.2 and 1.6 ± 1.2 for glare, halo, starburst, and ghosting/double vision, respectively. CONCLUSION: Despite the lower near addition of SBL-2 segmented bifocal IOL, patients achieved reasonable rates of spectacle independence and a low incidence of visual phenomena. |
