Abstract Details


To assess visual performance and subjective experience of patients implanted with the SBL 3 bi-aspheric, multifocal intraocular lens (MIOL) 12 months post-implantation


Private clinic, Solihull, United Kingdom.


Patients (average age 63.4 ± 12.3 years) were binocularly implanted with the SBL-3 MIOL (30 eyes). Twelve months post-implantation, assessment was made of: manifest refraction; uncorrected (UCDVA) and best corrected (BCDVA) distance visual acuity; uncorrected (UCNVA) and best corrected (BCNVA) near visual acuity; defocus curves - range +1.5 to -5.0 D in 0.5 Dioptres (D) in randomised increments and letters; Pelli-Robson contrast sensitivity (CS); halometry, using randomised letters and 45 degree increments; and patient’s satisfaction with unaided near vision, using the Near Acuity Visual Questionnaire (NAVQ).


Mean residual manifest refraction was +0.08 ± 0.42D. Mean UCDVA was +0.08 ± 0.17 logMAR. Mean UCNVA was J3, and BCNVA was J2. Mean CS was 1.65 ±0.14 log units. Halometry showed a glare profile of less than 1 degree of debilitating light scatter. Patients were very satisfied with their near vision according to NAVQ findings.


The SBL-3 MIOL provides a good visual outcome at distance and near with minimal dysphotopsia at 12 months. Patients were very satisfied with their uncorrected near vision.
