Blended Vision With A Monofocal Iol Inducing Positive Spherical Abberations In A High Myopic Patient.

Application of monovision with two RayOne enhanced monofocal intraocular lenses EMV (toric and non-toric) from Rayner (West Sussex, UK) to increase the depth of focus in a high myopic patient. 

Department of Ophthalmology, University of Heidelberg, Heidelberg, Germany.

A 56-year-old patient with high bilateral myopia (AL OD 28.14 mm; AL OS 27.26 mm;  subjective refraction  OD -13.5 -2.0 x 95°, OS -9.00 -2.00 x 160°) and moderate corneal astigmatism on dominant eye(DE) after cataract surgery had implantation in his DE enhanced monofocal lens RayOne EMV toric RA021T from Rayner  with emmetropization and in his non-dominant eye enhaced monofocal lens RayOne EMV model number RA0200E with target refraction  - 1,50 D. This combination aims to correct one eye for distance vision and the other eye for near, resulting in a full monovision approach with increased range of focus, thus allowing a broader spectrum of visual fields. 

Post-operative subjektive refraction 1Week after surgery shown manifested target refraction allowing in binocular vision logMar +0,1 (Decimal 0,8) and providing good vision at intermediate and near distances. Intraocular axial position of the toric lens in DE 1 week postoperatively was stable anticipated its supposed rotational stability. Subjective refraction, uncorrected and corrected visual acuity (VA), binocular [logMar] for distance, binocular for intermediate and near vision, as well as defocus curve 1, 3 and 6 months after surgery are still in evaluation.

Even in a high myopic patients application of full (1.5 D) monovision with two RayOne enhanced monofocal lenses EMV from Rayner proves to be a good choice, aimed to deliver a non-diffractive, figh quality vision with an increased depth of focus.
