I heard that are very good, practically no glare or other dysphotopsias. Why are not used that much as AMO, Acryosf and other lenses?
If you do an internet search on "about-eyes Nanoflex" there is an article about the new Star Nanoflex accomodating IOL compared to Crystalens and multifocals.
There is a good FAQ section in that article, that includes:
FAQ #1: “Why haven’t I heard of this lens before?”
Staar is a relatively small company compared to Alcon, AMO, and B&L (the big three IOL makers in the USA). As such, Staar simply doesn’t have the marketing budget to compete. Hate to break it to you, but doctors are just as likely to be swayed by marketing as anyone else. Whether it’s laundry detergent, a car, or an intraocular lens placed at the time of cataract surgery, we are all influenced by familiarity with a brand. Indeed, marketing studies have supported that familiarity breeds trust so the most heavily marketed brand tends to be trusted for that reason alone.
FAQ #2: “Why aren’t more surgeons using this lens if it’s so great?”
I can’t say for certain why the Staar nanoFLEX® IOL is not embraced by more surgeons, but I have a few thoughts on the subject:
It’s a plate haptic IOL. When plate haptic IOLs first came on the scene they were made of silicon which is a slippery, springy material. They could not be easily folded with forceps so required injectors to get them through a small incision during cataract surgery. As these IOLs left the injector they did so with significant speed and force. I’ve even seen a video of one that jumped out of the injector through the capsular bag and into the back of the eye! The Staar nanoFLEX® IOL, however, is not made of silicon. It’s made of Collamer®, which is a less “springy” material. I’ve found injecting it to be controlled and stress-free. Many surgeons, however, may simply not be willing to try another plate haptic IOL after their initial experience with silicon plate haptic IOLs.
The force of inertia (or habit). Everyone, surgeons included, tends to prefer what they are familiar with. Surgeons who have been using acrylic lenses (the most common type) may just not want to be bothered by trying out a different lens material which requires becoming familiar with a new lens injector, surgical technique, etc.
Not all surgeons are even aware of the nanoFLEX® IOL due to the limited marketing done by Staar. See FAQ #1.
Infelizmente, todos (incluindo os cirurgiões) são influenciados pelos discursos de vendas das grandes empresas.
Na época em que recebi a lente Symfony para meu olho direito (tendo sido influenciado por todas as vantagens anunciadas sem qualquer menção aos possíveis problemas de visão noturna), se eu tivesse escolhido uma lente monofocal, poderia ter sido a Nanaflex IOL. Isso teria sido baseado no artigo de 2015, "Minha Experiência Pessoal com a nanoFLEX® Collamer® IOL", do Dr. Alan Carlson, que faz uma forte recomendação para esta lente. No entanto, será sábio fazer uma investigação mais aprofundada sobre a lente antes de decidir procurar um cirurgião que a utilize.
The Staar Nanoflex IOL looks like a good alternative if you have no significant astigmatism.
In my case I have nearly 3D cylinder astigmatism in my eyes, so I require toric IOLs and this lens does not offer that.
So I am limited to monofocal torics, the Symfony toric, and the Trulign (Crystalens toric) IOLs, if I don't want the added complexity of cornea surgery.
Srarr também fabrica a Lente Implantável Toric de Colámero Visian, que é dobrável e projetada para corrigir astigmatismo. A lente está disponível para correção de 1,00 a 4,00 D de astigmatismo. Ela utiliza o mesmo material Colámero que o Nanoflex.
Thank you! The problem is bloody DYSPHOTOPSIA with hydrophobic acrylic, truncated/squared edges and probably refractive index=1.47. So now, after several months, I still have edge-glare, edge-flickering and halos. I refused multifocal lens because of that problems but I have them with monofocal too. I suggested the surgeon to use the nanoflex but she refused because she's not used to them and said that hydrophobic acrylic lens are the best on the market ...

Do your pupils dilate to 5mm or greater?
I've heard that becomes an issue with IOLs with smaller diameter 6mm or less.
I have normal pupils, I have a tecnis zcb00 monofocal 6 mm optic.
Não sei, mas na minha opinião todas as lentes intraoculares monofocais asféricas são basicamente as mesmas (tenho uma monofocal de silicone da B&L e praticamente não tenho ofuscamento).
Se você tentar relaxar e não se concentrar nisso, é muito possível que você se adapte a isso e não perceba eventualmente.
Hydrophobic acrylic, smaller lens size, squared edges, high refractive index are all things that make glare and other disturbance worse. There are many studies on it.
yeah, heard of this already but you cannot "forget" you have a psychedelic film in your eyes every day, for months.
Tenho pupilas normais, tenho um tecnis zcb00 (monofocal) com óptica de 6 mm. E sinto como se fosse um fio, como uma sombra, do lado esquerdo do olho esquerdo. Não posso mudar isso agora, então aprendi a aceitar para facilitar. Sou grato às pessoas que inventaram e desenvolveram até agora para me dar a visão de ver o mundo e desfrutar da natureza.
Agora tenho que decidir qual IOL monofocal devo escolher para o olho direito. O tecnis zcb00 tem IOL de forma arredondada além da forma quadrada? Minha cirurgia é na segunda semana de dezembro e tenho que informar o gerente da cirurgia em breve. Se eu escolher visão clara à distância, como a que tenho no olho esquerdo dominante, mais tarde posso precisar de alguns óculos para ficar sem óculos. Ou posso ter micro monovision e não sei sobre os números. Não vou optar pela monovision, porque já estou experimentando nuvem mental desde a primeira cirurgia. Porque meu olho direito desenvolveu catarata e é como viver com monovision. Obrigado pelas informações sobre o IOL de borda quadrada.
Tecnis zcb00 jas both side squared edge, frosted ... but it doesn't help against positive dysphotopsia.
Not all aspheric monofocal iols are bascally the same: some are made of silicone, other of water-based acrylic, other made of collamer, some of PMMA, some are thicker, some are thinner, some have squared edges, some have rounded, some have half squared and half rounded, some have frosted, some are biconvex and some not, some are plate, some are 3 pieces. It's like saying "all red cars are the same".
