My vision is better indoors in artificial light with Tecnis Synergy IOL, but very bad in sunlight conditions. I showed the optician who examined my eyes by checking my vision with outdoor lighting. Street signs across the road are blurry, but in the examination room I can read the first few lines, which are much clearer. I don't know why optometrists and ophthalmologists don't test vision in different lighting conditions. It's only when patients report back to them to complain of visual disturbances after IOL exchange or after prescription glasses.
sad to hear.. it might be related to pupil decentration or lens position vs pupil. and yes, industry are not rutinely checking vision at different conditions. some doctors are more accurate and passionate, some doing standard things. I wish you find a solution with your doctor
The following tests were performed for my eye measurement prior to my cataract surgery: IOL Master 700 Biometry Nidek AI Scan Biometry Corneal Labelling and Mapping Vector Analysis Ziess Atlas Toppgraphy Ziess Atlas Aberrometry Nidek Keratometry Laser surgery office Corneal Tomography Corneal Topography Epithelial Optical Coherence Tomography Residual Astigmatism Analysis Procedure performed: Refractive Cataract Surgery Advanced Technology Refractive Monofocal Toric Intraocular lens to Correct Optical Errors Post surgery my eye pressure went to 31mmHg from 17mmHg. The surgeon told me I have Glaucoma when prior to surgery my eye pressures were fine. I have been wearing glasses since my teens and had regular eye exams and had never been told I had glaucoma. Now I have to use drops for life to control the eye pressure or the other option my ophthalmologist suggested was laser surgery, with no guarantee of correction. Also my vision is a bit blurred after almost 6 weeks. Not sure if I should seek a second opinion…
Sorry to hear that you have blurred vision. What would you like to know? Honestly there might be number of reasons for that. ps: glaucoma is not a pressure. it’s a ganglion cells degradation and the pressure is one of the possible markers; and one of the influence points, but not the single reason.
@@iol-adviser, thank you for your response. I’ve never been diagnosed with Glaucoma or high ocular pressures prior to my cataract surgery. I was able to see clearly up close without glasses until my vision became cloudy because of the cataract in one eye. Thankfully I didn’t need cataract surgery in my other eye, I can still manage too see properly but hate the idea of having to put drops in my eyes for life and the side effects of doing that. I will not feel confident going for my other eye cataract surgery, when the time comes. Also were all those tests performed prior to my surgery absolutely necessary?
@@iol-adviser , thank you again for your advice. The surgeon I went too is highly recommend. One of the top surgeons in the city but he is too busy and rushed.
What about flickering light around the lens edge every time I move my eye. I see that along with an arcing shadow off to the side constantly unless I’m in a very dark environment. I’m 12 weeks out from IOL surgery and it isn’t getting any better.
I had surgery 6 days ago and couldn’t read anywhere. Today they looked in my eye and discovered I could see perfectly well with -1.25 cyl of astigmatism: all of his table even the line just below 20/20 I could make out. The lens was Toric and -2.25 and supposed to get rid of all of my astigmatism but here I am now 6 days post op with astigmatism -1.25. And guess what optometrist told me that at this stage they don’t even check the eyes with lenses just ask to read how many lines you see but because I had concern about focus he decided to “check” with lenses and that he doesn’t have statistics about those numbers with other people but assuring me that this is a common complaint and that it is early days and it will subside reduce!!! How??? There is no inflammation in retina and cornea, all other parameters he said are normal after the scan, the position of the Toric lens is correct as I asked him to check so he dilated me (they usually don’t do it for some reason), and still I have that astigmatism. Can that actually be true and it will reduce? One good news: during cataract not a single lens they put before my eyes produced any focus. It is a shame it’s such a lot of astigmatism still left as I paid a lot of money for this operation and the surgeon is very respected but how could he miscalculate so much? Something tells me it won’t go away. I still see a lot of floaters, vision fluctuates all the time. I’m actually getting sick with all of this experience. My second eye operation is coming with the same surgeon. Soon I won’t be able to write here anymore as I will lose the close sight forever. Also apparently I ended up even slightly hyperopic like +0.5 the machine gave the result, but the nurse said it will all change to 0.00 Going from -8.5 before cataract to +0.5 is a mocking really when I specifically told the surgeon that the biggest fear for me would end up hyperopic. I want to stay a bit myopic. I will do my best he said. What??? But in fact it doesn’t feel I’m seeing so well inside the home, it’s blurry. The optometrist also said it will reduce and that at this stage they don’t do tests with lenses. I’m gutted and can’t breathe. At the moment it feels like a biggest nightmare of my life. I wish I went with Rayner where doctor offered -0.75 and -0.5. I don’t need their zero vision. 😢
Well i am 75 years old, and i am not expecting miracles and getting back to my younger years vision. As long as getting the Mono Focal lenses in Nov 2024 make me see a little better in the distances and wear glasses for seeing things close I will be happy. Not expecting 2020 vision or how they work in different light conditions. All i can do expect a little better vision than what I see now.
Alex, it is my understanding that accurate measurements of the eye needing surgery need to be taken to come up with best IOL calculations. If cataracts prevent clear views of posterior segments, could that lead to incorrect calculations and not so good vision after the surgery? If doctors cannot see posterior pole/segment, how do they arrive at what IOL parameters should be used? Thank you
It depends on measuring method. If cataract is too dense, ultrasound method is used. Immersion is more precise than contact, however even contact method if performed carefully gives good results.
I had Eyhance Toric II 3 weeks ago. I wish I never had it done. Lost my distance near perfect vision. Now I have blurry,double vison. Don't get the surgery unless your in bad shape.
Sorry to hear that. So you have great near but bad far, correct? What was your refraction before and what you have discussed with the doctor as a result?
@@iol-adviser Don't know the refraction but he installed Eyhance diu 150 in one and the other diu 225. Before I had great distance vision and needed readers for inside dimmer light . Now my distance is blurred distance from about 30 ft to horizon. Images or signs etc have a shadow double look. Reading inside is a bit better. It's been 3 weeks since first eye 2 weeks since second eye. No change in vision since. If I look thru adjusted binoculars my distance is clear. My doctor said to wait to see if it gets better. I regret doing this because now I fear having to have glasses for driving or distance which I didn't need at all before. And the cost of fixing them so no glasses is out of my means. Plust the $3000 us I paid for Eyhance. Now were did I read ther is a good chance of Refractive surprise in all the videos or reading I did before.
I had very high sensitivity to light and the doctor said I have cataract.. my eye had started paining terribly in the past few months... That's why I got it done...😢😢😢😢
Not exactly. Regular astigmatism is ok, irregular not possible as with any traditional toric IOL (probably yet), but contrast is a function of optics and physics. And LAL, and LAL+ has no way to eliminate contrast loss, as other lenses like Vivity for example. Any EDOF will decrease contrast and CSF due to nature of the optics. The question is the amount of contrast decrease, but it's question of material and way of focus elongation via aberration or refraction induction.

@@truthteller6932 I believe that the best way not is to look for second opinion.
ps: taste seems reasonable

that's the most common problem - lack of time and inability or lack of willingness to communicate with the patient. That's why I'v started my project.

Light adjustable lenses might be the answer to some of the issues like contrast and astigmatism.
Not exactly. Regular astigmatism is ok, irregular not possible as with any traditional toric IOL (probably yet), but contrast is a function of optics and physics.
