Rayone Emv - Monofocal Plus Lens That Should Be Considered More Often Than Not

This posters aims to present surgeons’ own experience (real world evaluation) with RayOne EMV (Rayner, UK) monofocal plus IOL in bilateral cataract surgery, calculated for minimonovision to achieve greater depth of focus. 

Spektrum Clinical Ophthalmology Centre, Wroclaw, Poland

30 patients (60 eyes) with bilateral cataract, agreeing to and understanding idea of minimonovision (dominant eye set for emmetropia and target refraction of non-dominant eye set for -0.75 to -1.25 D). Surgery was performed under topical anaesthesia by the same experienced surgeon (DK). Postoperative examinations 1 day, 2 weeks and 2 months post-op included but were not limited to monocular and binocular uncorrected near visual acuity  (UNVA) and uncorrected distance visual acuity (UDVA). Patients were also asked to complete a modified VF-14 questionnaire with questions regarding performing common daily activities without optical correction and presence of dysphotopsias

Binocular UDVA: 74% of patients reached 6/6 on Snellen chart or better, and for 96% of patients mean UDVA both eyes was 6/6.5 or better. Mean binocular UNVA was 6/5.5.UNVA: 43% of patients did not require spectacle correction for reading and 91% were able to read an average book font. Halo or glare effect were noted in 5 cases but only in two of them resulted in lower score in patients’ satisfaction questionnaire. In three remaining cases patients gave 95% of maximum score and stated that halo and / or glare did not comprise their visual quality. Score in patients’ satisfaction questionnaire was 90% (drivers) and 92% (non-drivers) - it shows very high percentage of satisfied patients in both groups. 

Monofocal plus lens is a very good compromise between a good deal of spectacle independence, its price and coexisting ocular conditions allowing for its implantation. RayOne EMV IOL is an affordable and valuable option for patients who accept the need for glasses when reading (especially small print) but would like to increase their spectacle independence for everyday activities postoperatively and should be considered along with premium multifocal IOLs. Reducing spectacle dependence with the pseudophakic minimonovision technique may allow for even greater depth of field and can improve the functionality, autonomy and quality of life for many patients
