Abstract Details


To evaluate clinical outcomes with rotationally asymmetric, reduced addition multifocal intraocular lens designs (Lentis® Comfort MF15/toric and MF20/toric) implanted bilaterally in a cohort of patients undergoing cataract or lens replacement surgery.


Optegra Yorkshire Eye Hospital, Bradford, UK


Observational case series. The series comprised 169 binocularly treated patients. The mean age of patients was 62±8 years (range 41 to 85 years). Range of pre-operative spherical equivalent was from +11.38D to -14.25D with 8.0% myopia over -6.00D and 7.4% hyperopia over +5.00D. Follow-up took place 61.6±53.2 days after surgery. Implantations were consecutive and performed by one surgeon at a single site. Exclusions were made for amblyopia. Post-operative binocular uncorrected distance (UDVA) was recorded for 169 patients and binocular uncorrected near (UNVA) vision was recorded for 153 patients, along with patient satisfaction.


Post-operatively, the mean monocular UDVA was 0.01±0.12 logMAR. Post-operatively 100% of patients achieved binocular UDVA 6/12 or better and 88% of patients achieved binocular UDVA 6/6 or better. 100% of patients achieved binocular N10 or better UNVA, 98% of patients achieved binocular N8 and 89% of patients achieved binocular N6 or better. 89% of patients achieved a combination of at least binocular unaided 6/7.5 and N6. Mean post-operative spherical equivalent refraction was -0.21±0.58D. Patient reported satisfaction was high.


The MF15/toric and MF20/toric lenses proved to be an effective way to enhance both distance and near vision following small incision phacoemulsification surgery in this cohort of patients.
