Clinical Outcomes After Bilateral Implantation Of An Enhanced Monofocal Intraocular Lens In Highly Myopic Patients With Myopic Targets In Both Eyes

The aim of this study is to present the refractive and visual acuity outcomes of myopic patients after bilateral RayOne EMV (RAO200E, Rayner) intraocular lens (IOL) implantation targeting a myopic refractive outcome of -1.5 D in both eyes. Exclusion criteria: astigmatism >1.0 D, lens subluxation, diseases of the retina and nerve II, previous ophthalmological surgery, corneal diseases, active inflammatory process around the eye.

In this prospective single center study design, the target refraction was set to -1.5 D for both eyes. Pre- and postoperative examinations included monocular and binocular uncorrected distance visual acuity (UDVA), binocular uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA), monocular corrected distance visual acuity (CDVA), corrected intermediate visual acuity (CIVA) and corrected near visual acuity (CNVA). Follow-up visits took place at 1-2 days, 2 weeks and 2 months after surgery. Mean refractive spherical equivalent was examined. During postop visits patients’ distance-corrected near visual acuity (DCNVA) and distance-corrected intermediate visual acuity (DCIVA) were also assessed.

Interim analysis were conducted for 15 myopic patients (total of 30 patients), 8 women and 7 men with a mean age of 69.9±9.1 years. Mean postoperative MRSE was -1.58±0.11D. Two months postoperatively, mean monocular UDVA increased statistically significantly from 1.01±0.31 D to 0.54±0.3 logMAR (p<0.001). CDVA of the operated eyes averaged 0.15±0.1 logMAR after surgery. Mean UIVA and UNVA were 0.21±0.14 and 0.28±0.17 logMAR, respectively, while monocular CIVA and CNVA averaged 0.17±0.12 and 0.15±0.16 logMAR, respectively. The corresponding outcomes on DCIVA and DCNVA are 0.20±0.12 and 0.30±0.16 logMAR, respectively. In 73.3% of cases there was no need to remove far distance spectacles for closer distances.

Interim results from 15 myopic patients (30 eyes) with bilateral implantation of RayOne EMV display very good results over a broad range of distances utilizing a target refraction of -1.5 D in both eyes. Patients also see quite well in intermediate and near vision ranges without taking their glasses off, which can have a very positive impact on their quality of life. Myopic target refraction was chosen to enable patients seeing clearly for closer distances without having to take their far distance correction glasses off to which they had been used to wearing all their life. Thanks to the selected myopic target, high refractive accuracy and RayOne EMV’s increased range of vision optic design, they don’t have to take the glasses off to read.
