Is the enVista hydrophobic IOL by Bausch + Lomb good for a myopic eye?
Posted , 9 users are following.
I am a 66 year male, and need cataract surgery. My eye surgeon recommended the enVista hydrophobic IOL by Bausch + Lomb for me. I have been wearing glasses since early 20s after being found I had an uneven vision, with the right eye at 20/25, and the left at 20/200.
According to my surgeon, I would still need to wear my myopia glasses for distance viewing and driving after surgery, but should be able to see things up close without reading glasses. In his words, my life would be as usual post surgery as far as my vision is concerned.
I understand the DIOPTER RANGE of this enVista hydrophobic IOL is from 0.00 D to +34.00 D, which might be perfect for my right eye. However, is it ideal for the left eye without any myopia refractive correction?
I have no problem wearing glasses for driving as I am accustomed to this not so convenient reality. My primary aim is to minimize any possible issues down the road, such as “secondary cataract” that requires further treatment or procedures. From my limited reading on the internet, it appears that the hydrophobic IOL may decrease PCO formation and the need for YAK laser treatment.

Cataract surgeons often say if you have myopic all your life, then you should stay myopic. Intermediate vision is a good compromise between near and distance. It certainly worked fine for me. Minimonovision works great for many but not all people, especially those who pay a lot of attention to detail or are sensitive to bodily sensations. It's usually better to try it out first with contacts. But in any case, eyeglasses can always correct your vision regardless of what you do.

With monofocals, I'll agree with Lynda on targeting intermediate for myopes, especially if you can tolerate some mini-monovision.
One big advantage is that it eliminates the risk of hyperopic surprise. There's a 10-20% chance of missing targets on the hyperopic side by at least 0.5D and those risks are higher if you've previously had eye surgery or have difficult to cure vision conditions.
Targeting plano on the first eye, then getting a +0.5D or +0.75D result leaves you with very few good options for unaided near/intermediate vision, even if you are willing to tolerate some mini-monovision.
As an alternative, consider targeting -1.25D or so on the non-dominant eye first. If that target is achieved, you should see reasonably well beyond 45cm (17 inches) and then you can decide whether you want better near or distance and target the dominant eye accordingly.
A hyperopic miss on the first non-dominant eye leaves you at -0.5D or -0.75D, probably decent driving/distance vision, probably good intermediate down to about 60-70cm. You'd need to decide to target the dominant eye for near (-2D ) or try to closely match the non-dominant eye for binocular vision and use readers for near. Not that bad of an outcome.
A myopic miss on the first non-dominant eye leaves you at -2D or -1.75D. In that case you could target your dominate eye for distance and shoot for -0.5D in the 2nd eye. All of these outcomes are far superior to the ones available after hyperopic surprise in the first eye. For myopes who don't mind taking some risk of needing glasses for distance, targeting intermediate on the first eye gives you better options when targets are missed and avoids the risks of hyperopia.

Thank you, Lynda and Greg!

how would a high myopic patient feel if the distance target is missed and become hyperoptic? i heard the patient can be very uncomfortable but what does uncomfortable mean?

this does make sense.
