Cataract Lens Selection?

Cataract Lens Selection?
Many PPRuNers have had cataract ops and I would like to hear their experiences from a pilot's view.
My ophthalmologist has been muttering about cataracts for the last decade and lately oncoming headlights on two lane roads at night are showing starburst patterns. I'm off for preop ocular measurements in a couple days.
Multifocal intraocular lenses are frowned upon by aviation authorities because of halos and other effects. I'm perfectly happy to continue with eyeglasses and single focus IOLs.
For distance, my eyes are correctable to 20/20 & 20/30. Hopefully afterwards my vision could be correctable to 20/15 in both eyes.
For around the house and reading music an arm's length away, I'd be happy with IOLs that let me do that without glasses. Presently I use glasses with a reduced correction.
Likely I'll need readers for close up work. Today I do without glasses for this.

I had cataract surgery about 18 months ago. The lens used were Johnson and Johnson eyehance. Prior to surgery eyes were deteriorating rapidly and over the course of 6 months I had about 3 different glasses made up but none could deal with the problems of focusing on intermediate and far distance.
You are right about the multi focal IOL,s..... after investigation I found these lenses are classified as monofocal IOL (while classed as monofocal manufacturer has done some magic with them and they act more like a multifocal) and after some arguments with CASA they were accepted as such (they were new to Australia and I found a surgeon that had previously used them on a Qantas pilot so that obviously strengthened my case) and 1 month after the second eye had been done I had my class 1 medical back. On doing my eyetests with the CASA DAME - he was pretty amazed at my results and said he wanted these lenses for himself.
Eye test results by surgeon post surgery after 3 weeks -
Vision RE (unaided) 6/6
Vision LE (unaided) 6/6;
Vision Both eyes open 6/5 (unaided)
Near vison both eyes N5 (unaided)
So, I am very pleased with them.
Far distance - great. Intermediate great. And for the first time in 10 years I don't need to wear glasses for reading in bright light anyway.... i do chose to still wear reading glasses when on computer.
Obviously risks as always with surgery - i believe these lenses also had reduced risk of halo at night, certainly I have had no issue.It would probably be sensible to contact your authorities to make sure acceptable for pilot certification.

Just an elderly PPL on self-declared medical, who hasn't yet flown since operations.
I've had both eyes done. Left eye on 5 December was quickly very successful. Right eye 19 January took longer to settle, but very happy with both. Old glasses are useless but I can read print, computer, and distance without them. Wear sunglasses but no problems 10 hours out in sunshine now.
The big problem which I wasn't expecting is due to avoiding exercise - at 83 I'm still not back to my exercise fitness of 3 December.

As always choose your surgeon carefully..... I spent a long time on this before having IOLs myself and ended up very happy. I ruled out multifocal early on. We discussed correcting one eye for near vision and one for distant vision but just went for best correction on the worse eye and let it settle before having a comprehensive reassessment and discussion about the second eye. I havent worn glasses since. No halo, but I do notice I need light to read and also wear sunglasses more. Results far better than those necessary for a Class 1
Maoraigh1 I dont understand your comment about exercise fitness - I presume the operation was undertaken awake with a local anaesthetic block so it would be unusual to have any effect on general health. both my procedures were totally painless and hassle free - doctors are the worst patients but I see absolutely no need for any sedation.

I was told to avoid heavy exercise. As I live on a clifftop near a headland, strong winds restricted my walking, to avoid blowing dust/sand etc.. I got unfit, and when I restarted exercise I damaged bits.
Now getting back to exercise without pain. At 83 fitness is quickly lost.
PS Lenses Johnson & Johnson.
I just accepted surgeon without research, not cheap and a guy I know was happy with his work.

Again, Pprune at it's best.Comforting stuff. I was diagnosed with Diabetic Odeama. Pandemic issues delayed treatment for one year. Discovered that it is very common and private guys are making a fortune. I qualified for NHS. Terrifying injection treatment direct into eyes. Proof that "cheaper" medicine was working (E400 a pop) before "expensive" drug (E800 a pop) and initial mess up means I have now endured 11 jabs.
Fabbo local Surgeon now going for three Laser blasts before progressing to cataract ops. Just his way & seems concerned with the cataract ops leading to liquid build up.
Interesting to read other's, specially Radgirl's experiences.
Totally unable to watch my fave Alien Abduction movies though. Also ditched the awful varifoculs after I kept tripping over, bumping into things and then peeing all over the guy's shoes beside me at the Taverna loo !
