My name is Alex, and my Eye surgery explained channel - all about vision, new vision recovery technologies, eye deceases, and more.
My goal is to help peoples, having vision problems, from low myopia to cataract, glaucoma, or age-related macular degeneration to get valuable information.
I will talk about deceases or eye conditions and treatment options available up to date, explained not by a doctor, means in simple words, and truthfully by an expert in the ophthalmic industry.
Ask your questions below, and I will try to help!
I have created that channel as my passion to help peoples to get the maximum of their sight.
Feel free to ask about IOL selection criteria, IOL specifications and professional suggestion from experienced clinical application specialist.
Please note, that I am not a doctor, and your health conditions and any actions related to that has to be discussed with your doctor only.

Not sure you will read thisâŠ. I had surgery in 02/2024. Dr said my best option was the LAL+. I asked him if it was mono vision, he said NO. Well, it is and I canât do mono vision. I am left eye dominant BUT my right eye is the strongest. I think there is something wrong with my left eye. First adjustment set left too far and right to close. Life went to hell. I could only see in a 10 by 10 foot room. Anything farther was hell! Double vision and dizziness. They keep telling me my eye tests are perfect (in a 10 by 10) that I can see far and close at 20/20. So they adjusted my right eye to be closer to the left eye. Dizziness went away but still unable to see anything after 10 feet. The 3rd adjustment I asked to set to both close because I couldnât take the mono vision anymore. I am NOT OLD! I am only 58. I am healthy! Now they keep giving me contacts and I am supposed to test them. The astigmatism was NOT FIXED! I donât know how long I can take this! Now they are ghosting me. I have more information but hard to add all to this tiny comment box.

contact wearer 30+ years. very miopic. -16 left eye, -11 right eye. started reading glasses late 30s. multi-focal contacts did not work for me. Had slight cataracts late 50s. Had rle at 58. wanted best distance vision possible. Had monovision Alcon IQ both eyes. Now 10 years later still have 20/15 left eye,20/20 right eye. no glare no halos. wear reading glasses.+2. no big deal. Best decision I ever made. Shoul have done it years earlier. just amazing to wake up and see clearly
A great story! Glad about you, and thank you for sharing your lens exchange experience.
All the best!
Do you need glasses for medium distance when using a PC? How does your reading in dim light compare to your old healthy eye?
@@atalayonline computer.......just my readers , at home screen is my 50 inch tv on wall, no glasses. reading in dim light no problem with readers. i fix watches for a hobby, sometimes use 2 pairs, need to buy a jewellers magnifier. Actually vision is better than before surgery when using contacts and readers
Thanks!
Glad that you like đ
And thank you for your support!
Hi Oleksii. I have been delaying having cataract surgery since a very comprehensive eye exam by an opthalmologist about 4 months ago. I found out that I have no health or eye conditions that would prohibit the surgery. Also he seemed to take many measurements. His recommendation was monofocal Eyehance lens set for distance vision. On one eye since I have slight astigmatism, he'd do a limbal relaxing incision.
My question for you is do the measurements that determine the power (and size?) of the lens need to be redone since it's been a few months. Or is it unnecessary because the surgeon determines the final refraction details at time of surgery? Thanks for the info that you impart in these videos.
Hi! Thank you for your question.
Generally there should not be any issues if nothing special was detected like corneal abnormalities or tear film issues. Eyhance is a good lens with no issues as well. So I guess your data shall be fine.
The doctor determines optical power of the lens, size is the same for all patients as lens adapts to size of the capsular bag.
If you are concerned, and Iâm trying to put myself to your shoes, Iâd ask doctor just in case to have a short look to corneal topography to be on a safe side with astigmatism and dry eye.
Hope this helps :)
I am choosing mono lense in my right eye, when the other eye is done
Can it be adjusted or selected to improve the closer vision if need be.
Hello Oleksii, my left eye sees 100% and my right eye sees 60%. I have cataracts in both eyes. It is a slowly progressing type of cataract, developed due to allergy eye drops. I think my right eye will have surgery before my left eye. What would you recommend to someone like me who is healthy? I'm 38 years old. Your general opinion is incredibly important to me.
So basically, cataract surgery removes the foggy vision but doesnât restore the full range of vision as before without the use of optical aids such as glasses or contact lenses.
Yes, if monofocal lens is used and No is presbyopia corrected lens is used. But the glasses free range depends on lens type and model.
@@iol-adviser , thank you for clarifying and all the details you provide in your videos.
Sir, i used monofocal lens for my right eye and now i can't get focus, things were blur near and unable to read, is this normal because my aunt can read without any glass after using monofocal for her cataract surgery
It depends on eye refraction , so general rule is with monofocal IOL you see sharply at far and blurry at heart or opposite.
How multi focus IOL works? Multi-focus glasses and over the eyes lenses AFAIK require to look in several directions (e.g. straight - far, down - read) to use different parts of the glass. Is it same with IOL?
A great question.
Generally no- you will always have same multifocal picture whenever you look.
Try to watch my videos about multifocal lenses and glasses use on a channel and for example Alcon Panoptix review. It shall help.
@@iol-adviser I've wanted "Alcon Panoptix trifocal ". You said it has triple focus something, not how it is achieved. To understand, let me start with a question: with natural eyes one cannot focus both on a finger/pencil in front of the eyes and at infinity at the same time. Can one do have in-focus view of both near and infinity at the same time with trifocal IOL?
@@BobAlison Trifocal intraocular lenses (IOLs) like the Alcon PanOptix are designed to provide clear vision at three distinct distances: near, intermediate, and far. However, it's important to understand how they achieve this and what it means for your vision post-surgery.
With natural eyes, as you correctly pointed out, one cannot focus on both near and distant objects at the same time due to the eye's limitation in changing its shape (accommodation). The eye can focus on objects at different distances by changing the shape of its natural lens, a process that becomes less efficient as we age, leading to conditions like presbyopia.
Trifocal IOLs work differently than the natural eye. These lenses have rings or zones set for different distances, which divide the light entering the eye so that part of the light focuses on near objects, another part focuses on intermediate objects, and another part focuses on distant objects. This design does not replicate the natural accommodating ability of the eye but instead provides focus points at preset distances.
So, while with a trifocal IOL like the Alcon PanOptix, you can have clear vision at near, intermediate, and far distances, it doesn't mean you can focus on both near and far objects "at the same time" in the way a single object is in focus. Instead, the lens allows for clear vision across a range of distances, but your brain will need to adapt to selecting the appropriate focus for any given view. This process is known as neuroadaptation, where the brain learns to select the focus that gives the clearest image based on what you are viewing.
It's also worth noting that the split of light between the different distances can sometimes lead to phenomena such as glare and halos around lights, especially at night. However, many patients adapt well to their new vision and enjoy the benefit of reduced reliance on glasses or contact lenses.
@@iol-adviser Very good question by Bob and answer by you. I'd wondered exactly how the images at different distances provided by a trifocal lens gets sorted to one image, the brain's a wonderful thing to be able to do neuroadaptation.
Just play at .75 of normal speed. Problem solved.
Thank you for suggestion , Iâll improve :)
Think he is putting alot of info and it is hard. Good speed in my opinion.
Thank you for your support )
Well, honestly iv tried to listen myself again and speed seems to be ok. For me))
Interesting.
Alex, IMO English here is understandable except surgeon/surgery (u sound in place of er).
Oh, cool! đ thank you for suggestions.
Iâll put more attention saying
Cataract surgery and
Talk to your surgeon
You help me to improve , as I believe the knowledge and data about cataract surgery and IOL choice has to be shared openly with the patients.
thank you for this information, but i have to interject here, that your videos are edited with hundreds of cuts, plus the fact that you speak extremely fast with a LOT of information, plus there is a bit of a language disconnect (into english), makinig your videos very confusing and almost unwatchable, as i feel like i'm on a rocking ship. if you could slow down, with no edits, or fewer edits, and not give so much meandering information, it would be much more clear what you're referring to. at some points in this video, i'm not sure if you're referring to the monofocal, or the multifocal, or natural lens, etc, and i'm replaying the video multiple times. (i'm familiar with all the eye/surgery terminology, all the lenses and their technologies, etc). you're videos are almost unwatchable, i'm sorry to say, as it seems you are highly educated and informed about the subject.
Yep, agreed that this one is one of the worst.
No time to prepare better.
Sorry. Maybe Iâll do less frequently but better.
Just like the iol/ brain adjustment Alexi describes you need to adjust your perception of the video content, which is often cramming lots of info in as to not make the duration overly long. Viewers have short attention spans, unfortunately.đ
I'll do next video about 1 short topic for low myopia cataract cases and IOL selection specific, and will try to make it short, with less details and thus hopefully will need to think less on how to explain and keep it less than 10 mins.. we will see how it will work

oh, sorry to hear your experience.
what brings you to the surgery? cataract, or it was RLE?
what refraction and visual acuity you had before, and what you have discussed with your doctor as the expected result?
