Presbyopia Correction With The Use Of A New Enhanced Mono Focal Intraocular Lens

To determine the feasibility of the use of a new enhanced monofocal lens to correct presbyopia in cataract surgery 

All surgeries were performed by the same surgeon (MJ Botta, presenting author) implanting in all cases  a monofocal lens with modulated positive spherical aberration, from February to June 2021.  All patients had a follow up of at least six months.   Financial disclousure: the presenting author recieves lecture fees from Rayner UK.

Series-case report of forty eyes of twenty patients who underwent cataract surgery were implanted with a new enhanced monofocal intraocular lens (Rayone EMV) from February to June 2021.  Preoperatively UVA, BCVA, contrast sensibility and eye dominance were establised.  Non dominant eyes were targeted for lens implantation with an miopic offset of minus 0.50 diopters.  Dominant eyes were targeted for lens implantation for emmetropia.  Postoperatively UCVA, BCVA, contrast sensibility, defocus curve, near UVA and effective lens position were assesed.  The follow up was of at least six months in all cases.  

Thirty-five eyes achieved 20/20 far UVA postoperatively, five eyes achieved 20/25 far UVA.  Twenty non dominat eyes achieved Jaeger 3 or better.  No patient complained of visual difficultties with binocular evaluation of far uncorrected visual acuity or dysphotopsias.

Enhanced monofocal lens with an offset of minus 0.50 diopters in the non-dominant eye is effective for achieving functional near acuity without compromising far and intermediate visual acuity.
