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.

Thanks ! Tomorrow, March 25, I will have a pre-op exam and measurements by my surgeon. Then on April 4th, I will have cataract surgery on my left eye, followed by cataract surgery on my right eye two weeks later. I have been diagnosed with Bulious Retinoschisis, and Cogans corneal dystrophy. Thanks for sharing your knowledge with us. I live in the San Francisco bay area, All the Best, Bob
thank you for your comment and support!
do you have any concerns or fears related to your surgery? any questions unanswered or not discussed in your mind?
Alexi thanks for reply. I will be visiting my surgeon in a few hours from now. I will reply back after my pre-op visit with my surgeon. Bob
@@iol-adviser I had my cataract surgery on my left eye a few days ago, April 4th. The doctor implanted a mono focal toric lens adjusted for far vision. I tested 20/25. On the far left peripheral, I see a dark , crescent shaped band. When I move my eye left to right, the dark band kind shimmers or vibrates. The doctor said that "should" go away over time. Your thoughts ? Thanks, Bob
@@bobclarie the dark arc after IOL implantation is something that happens and will disappear with time, that's correct. If you see vibrations, it might be something that will not disappear as it might be related to ciliary body ligaments weakness and it is eye condition which some people may have.
Hello Alexi. I had IOL exchange procedure already and have commented before in other videos.
In hindsight, if I knew about surgical complications I would want to also know about IOL lens extraction if there is a significant problem with visual outcomes and/or problem with the IOL implant, that cannot be solved without extraction.
I am facing this possibility. People should also be know about lens extraction and replacement before YAG as well as the extra risks if done after YAG. So trying to establish with ophthalmologist if all causes of visual issues are exhausted before YAG option.
Also, the issues with replacing lenses after lens extraction - premium lenses much harder to implant into posterior capsule post YAG (many ophthalmologists won't do it) because of burnt open hole in the posterior capsule.
After lens extraction, monfocal lenses may be the only option (implanted into the anterior capsule instead). So possibly back to wearing glasses if monofocals the only possibility - after paying premium lens costs and long time plus additional costs to resolve this issue.
Thank you for your comment and sharing your story with us.
It is part of complications and future strategy to be discussed indeed, and not every surgeon is able to discuss that.
I'd like to note that premium IOL is also possible to exchange, and it is not desirable procedure at all, but if needed it could be done - the only questions are surgeon skills and every eye specific conditions which may apply. any way - the best case scenario is to select the proper IOL for an individual needs and carefully measure and calculate to avoid needs for explantation and exchange.
I hope that your case will end up successfully..
Alex, what are the odds of retinal detachment after a cataract surgery? I am high myopic (-7-8). The surgeon said that myopic eyes before surgery are stretched in attempts to see, but after surgery, there is sort of no need for them to. So, what is the possibility for the myopic eyes to contract, which would lead to retinal detachment. Any info will be much appreciated. All your videos and comments are very helpful and informative. Thank you
Cataract surgery for individuals with high myopia (-7 to -8), it is acknowledged in the ophthalmologic literature that high myopia (> 6.00D) indeed poses a significant risk factor for retinal detachment, particularly when this condition exists alongside lattice degeneration.
Typically, the structural changes to the eye associated with high myopia (like elongation) are permanent, and while cataract surgery can correct the lens' opacity and improve vision, it does not alter the fundamental shape or size of the eye. Therefore, the risk factors related to the structural elongation of the eye contributing to retinal detachment remain pertinent even after the lens's clarity is restored through surgery
Hello Alex. What are the odds of the capsule rupturing during a routine cataract surgery? Are the rupture odds higher for a posterior subcapsular cataract vs the other types? If the capsule ruptures, how it is corrected? I also heard that a patient selects Vivity and the capsule ruptures, the selected IOL cannot be implanted and the patient would have to settle for something else. Thank you
The odds of the capsule rupturing during routine cataract surgery are generally low, typically around 1-4%. However, certain factors can increase this risk, including the type and severity of the cataract, the patient's overall eye health, and the surgeon's experience.
Regarding different types of cataracts, posterior subcapsular cataracts (PSCs) can present a higher risk for capsular rupture. This is because PSCs often lead to a thicker and more fibrous posterior capsule, which can make the surgical procedure more challenging. Other factors that might increase the risk include advanced age, high myopia, or conditions like pseudoexfoliation or diabetes.
If the capsule ruptures during surgery, the surgeon must adjust the procedure to manage the rupture and ensure the safety and potential visual outcome for the patient. Typically, the surgeon will attempt to stabilize the remaining capsule and modify the choice or positioning of the intraocular lens (IOL). If a small portion of the capsule is involved, the surgeon might still place an IOL into the remaining capsule bag or in the sulcus (the area between the iris and the remaining capsule). If the rupture is more significant, the surgeon may need to opt for an anterior chamber IOL or a sutured IOL, depending on the situation.
In the case of specialized IOLs like the Vivity lens, which are designed for specific placement in the lens capsule, a rupture may indeed prevent its use. If the capsule is not intact enough to securely hold the Vivity IOL, an alternative IOL, typically a more standard option, may need to be used. These alternative IOLs may not offer the same range of vision benefits as Vivity but will still provide significant improvement in vision post-surgery.
Alex, thank you very much for your very informative reply. You are most helpful. I really appreciate it!
Alex, what is the likelihood for IOL haptics to loosen with time and lead to the IOL shift that would make vision worse? Since the haptics are non-organic matter placed in organic matter (eye), could aging cause eyes to become softer like the rest of aging body :) and release the haptics that were formerly firmly put in place? If this happened, what could a person do to help vision assuming YAG laser was done years prior?
nothing special shall be expected. The haptics is normally stable, the capsule shrinks around the IOL and holds the lens well. The source of issues might be zonular fibres, but it is not related to the IOL haptics and there is no way to do something as far as I know.
Doctors say IOL will last 'a lifetime.' If most people have cataract surgery at age 75-80, then 'lifetime' is not really that long considering average life spans. Are the statistics on IOL performance 20,30,40, and may be 50 years after surgery? Will a person be able to see just as well or close to it decades after surgery? Thank you
Most studies and clinical data focus on the performance of IOLs for around 10 to 30 years after implantation because long-term data beyond this range is less common. There isn't a lot of data for 40 or 50 years after implantation simply because the materials used in older IOLs are different from those used today, and also because many patients do not live significantly beyond this time frame post-surgery.
There are 3 main IOL materials used today
PMMA - since 1950th
Silicone - since 1980th
Hydrophilic - since late 1980th-1990th
Hydrophobic - since 1990th
So, generally I believe there is no concerns shall be taken into concideration.
@@iol-adviser I appreciate all your expertise. Thank you for being so thorough and very informative.
