Bilateral Simultaneous Cataract Surgery With New Rayone Emv Toric Intraocular Lens

This case report can be used to assess the new RayOne EMV Toric RAO210T intraocular lenses in correcting astigmatism. The lens was launched at ESCRS 2022. The expected improved unaided monocular and binocular visual acuity and spectacle independence are key advantages to these lenses. 

Our patient is a 73 year- old female patient who was first seen in January 2023 in Spire Hospital, Bristol and underwent simultaneous bilateral cataract exctraction under general anaesthesia on the 18th February 2023.

The patient presented with bilateral reduced vision which started approximately 2 years ago in the left eye and was of a new onset in the right eye. On slit-lamp examination, the patient was found to have bilateral nuclear sclerosis and posterior sub capsular cataract in the left eye. 
 
The refractive error of the patient before surgery was -4.00 D / -2.00 D @ 25° in the right eye with a Corrected Distance Visual Acuity (CDVA) of 0.1 decimal, and OS -4.25 D / -4.00 D @ 167° with a CDVA of 0.4 decimal. 
 
After discussion of all aspects, a decision was made for the cataract extraction and implantation of RayOne EMV Toric with target postoperative refraction of -0.20 in the right, dominant eye and -1.00 in the left, non-dominant eye. Joint decision for general anaethesia was made due to high patient anxiety. 
 
Four days postoperatively, the patient has an uncorrected distance visual acuity (UDVA) of 0.1-0.2 decimal in the right eye, 0.3 decimal in the left eye and a binocular UDVA of 0.0 decimal. Uncorrected Near Visual Acuity (UNVA) was N8 in the right eye, N6 in the left eye and binocularly N6. No photopsia was reported by the patient. Our patient was very satisfied and is no longer using spectacles for her activities of daily living. 

In summary, we believe that the RayOne EMV Toric intraocular lenses provides good near, and far vision with a high degree of patient satisfaction. Our case also shows that there is little to no risk of post-operative photopsia and glare at night driving.
