Mini-monovision with Eyahnce and RayOne EMV
Posted , 9 users are following.
I got my right (dominant) eye surgery done a week back and I got J&J Eyhance (Plano distance) in my right eye. So far, my experience with this lens is good - especially if I look with right only. If I use both eyes (which I have to 😃), the experience is OK (it maybe due to brain switching/selecting b/w the eyes). Also, the cataract in my left is pretty bad, which is creating too much difference b/w the two eyes. Now, I feel I should get my left eye surgery soon.
Currently with my right(operated) eye, intermediate vision is fine, distant vision is excellent and the near vision (fine prints and smartphone use) is blurry.
I used this forum and learned lot about different lens options. In fact, I came up with the Eyhance idea from this forum and discussed it with doctor.
For left eye, my doctor was suggesting to go with a mini-monovision with an offset of 0.5D to give better near vision. I recently came across RayOne EMV option in this forum and I am wondering I should go with RayOne EMV with same offset or different to get better overall experience (better near vision and no/less sacrifice in intermediate & distant vision). I haven't discussed the EMV option with my doctor yet, I have a follow up appointment next week.
Any expert suggestions for my situation? Should I simply go with Ehyance lens in my left eye as well or the EMV lens for better overall experience?

There's another issue regarding the RayOne EMV, namely, that it's made from a hydrophilic material. Obviously, the FDA, in approving the IOL, didn't think it disqualifying. But there are studies concluding that hydrophilic IOLs are associated with a higher risk of calcification and PCO than hydrophobic materials, used, for example, by both Alcon and J&J.
Search, for example, on Should We Abandon Hydrophilic Intraocular Lenses? by Gryzbowski, et al., in Am J Opthalmol for May 2022, a November 2017 article by Zhao, et al., Comparison of hydrophobic and hydrophilic intraocular lens in preventing posterior capsule opacification after cataract surgery: An updated meta-analysis.

Based on this following article (see Google search term below) the studies on the hydrophobic vs hydrophilic debate are not really conclusive, not to mention there are at least several other factors that evidently impact PCO development (patient age, iol design, the patient themselves, the procedure itself, and others). The mechanisms are still not even fully understood. Is there a higher chance of PCO developing on a hydrophilic iol vs hydrophobic, ALL ELSE EQUAL? Perhaps. Does that mean a patient or surgeon should make their iol choice based on that factor? More than likely not.
Google:"Factors Affecting Posterior Capsule Opacification in the Development of Intraocular Lens Materials".

I didn't mean to suggest that the studies I referenced are conclusive. That's one of the reasons I noted the FDA approval for the RayOne. It comes down, I suppose, to the risks one's willing to take and the gains one expects or hopes for. For present purposes, the gist of the study appears to be: "There is sufficient evidence to suggest that IOL material can influence the propensity towards PCO development. However, the influence of material wettability on patient's susceptibility to PCO cannot be fully established until additional targeted clinical studies with larger population studies are performed." (Pages 13-14).
