Purpose

Purpose of the study was to show differences between postoperative results after bilateral cataract surgery with implantation of RayOne EMV IOL (RAO200E, Rayner), either targeted for emmetropia (Group A) in both eyes or for modest monovision with max. 1.0 D difference between dominant and non-dominant eye (Group B).

Setting

Zaglebiowski Clinical Hospital, Ophthalmology Ward in Bedzin, WSB University Dabrowa Gornicza

Methods

In Group A - 50 patients targeted for emmetropia in both eyes and Group B - 50 patients targeted for emmetropia in the dominant eye and for -1.0D in the non-dominant eye. The IOL power was calculated with the IOLMaster 500 biometer. Examinations included CDVA, UDVA, UIVA, UNVA, distance, contrast. The follow-up examinations were performed at 1 day, 2 weeks, 2 and 6 months after surgery. Exclusion criteria were corneal astigmatism >1D, corneal, retinal or optic nerve pathologies, lens subluxation and previous eye surgery.

Results

After the operation, there was an improvement in visual acuity for distance and near vision in patients, while functional spatial perception was maintained. Most patients in group B reported satisfaction with their visual quality and limited need for additional near vision correction. Tolerance of monovision was good, In 16% of cases, additional near vision correction was required or monovision was abandoned in favour of symmetrical near correction due to adaptive disorders.

Conclusions

The use of monovision in patients following cataract surgery with Rayone EMV implantation is an effective strategy to increase independence from near vision correction. Tolerability of this method is high, although some patients may experience mild adaptation difficulties requiring modification of the refractive strategy. Appropriate qualification and a monovision trial prior to surgery can optimise results and increase patient satisfaction.
