The length and width of the streak is dependent on the brightness and width of the light source -- in only the right eye. Looking at a bright light bulb will provide a streak crossing most of my visual field (always at the same roughly 45-degree angle from upper right to lower left) exactly the width of the light bulb. The streak is perfectly straight and seems to fade away at the far ends. Opthalmologist just shrugs. Optometrist suggested perhaps I'm seeing the edge of the implanted lens, but wouldn't that be curved? I don't know the brand of the IOL, but it was toric with heavy astigmatism correction.
Prescription before surgery:
R +1.50 -3.25 x100
L +4.50 -3.75 x077
After surgery:
R 0.25 -0.75 145
L 0 -0.5 85
Different doctors may account for the difference in angle.
What might be causing these streaks and is it possible to get rid of them?
Please disregard everything beyond "cataract" and before "surgery" in the title. I didn't realize it copied there too :-(
I don't know what the answer is but I do know how frustrating it is when something goes askew and no one will take responsibility for the results.
many drs seem to be in a cloud not always putting the patient first and fix issues after cataract surgery. After 2 Lenses and laser I was dismissed that's all they could do don't know why my vision is worse.
hope that you continue to search for a eye professional who will help give you some answers rather than dismiss the issue.
i have asrignatism and cater act surgery resulted in worse vision than before surgery.
so I'm resting the eye for now. Hoping technology will come up with a better solution.
The cataracts themselves weren't that bad, I just wanted to get rid of the farsightedness and astigmatism -- which glasses never completely corrected. The result isn't perfect, but I'm really happy anyway. This is a minor annoyance; I'm surprised that my ophtho doesn't know what it is, but the rest of my body is weird too -- so why should my eyes be any different?
Did you spring for the toric lenses? Well worth the $1K each, I think. A friend is contemplating Sympfony multifocals (or whatever exotic descriptor they're using) at $3K each, so I shouldn't complain. I've been told by different docs that multifocal IOLs wouldn't work for me as well as single-vision lenses, so I bowed to their judgment. Monovision contacts work pretty well...
Yes ti rice and symfony and laser. No one will fess up. As far as I'm concerned I'm not ready for the other eye yet.
i cannot see a sign 4" letters 5' away. Before cataract surgery I could see a street sigh several yard away.
im happy that your doing well and have explained the issue that has been at the bottom of your frustration yet can see well. That's a good thing.
my sigh is double and blurry. Hoping to see another dr soon.
I have eave shooting streaks in my eye and its occasional I think it's fron light reflection on a prism like structure in my eye. Also have the dreaded black spots floaters, but have gotten used to both and rarely do they bother me.
wish you well on your journey.
Flashes when you squint hard? Apparently those can be normal too. I read elsewhere that IOLs can be removed (the additional ones certainly can, so why not the replacements?) so perhaps you'll get lucky. Floaters are annoying -- trying to figure out the eye-gymnastics required to move them to a less-annoying place isn't easy. They eventually get reabsorbed, though.
"Leí en otro lugar que los IOL pueden ser retirados (los adicionales ciertamente pueden serlo, entonces ¿por qué no los de reemplazo?" Creo que por "los adicionales" te refieres a las lentes fáquicas (lentes que se usan en personas que aún tienen su lente natural), como la Staar Visian ICL. Esas se pueden retirar con bastante facilidad, es más o menos el mismo procedimiento que el de implantarlas. Se colocan en la cámara posterior (entre el iris y el lente natural). La cirugía de cataratas retira el lente natural y lo reemplaza con un IOL. Ese IOL se puede retirar, pero no es tan fácil como retirar una lente fáquica como la ICL. El IOL de reemplazo generalmente está dentro del saco capsular (que antes sostenía el lente natural) y el saco capsular generalmente se pliega alrededor del IOL de reemplazo, por lo que retirarlo conlleva riesgos adicionales de desgarro o daño al saco capsular, lo que puede significar que ya no se pueden tener IOL estándar (como el symfony) pero se necesitan especiales que no vayan dentro del saco capsular.
Thanks. I thought the phakic lens went in front of the natural lens and was clearly wrong. I'm kind of glad I chose single-vision toric lenses (ophtho thought I would have better vision with them than with any sort of multi-focals two years ago) and don't have to make any more decisions.
Las lentes fáquicas se colocan frente al cristalino natural. La superficie externa clara del ojo es la córnea. Entre la córnea y el iris (el músculo bellamente pigmentado que dilata o contrae la pupila) se encuentra la cámara anterior. Entre el iris y el cristalino natural se encuentra la cámara posterior. Por lo tanto, la cámara anterior está antes del iris y la cámara posterior está después del iris. Pero todo esto está frente al cristalino natural.
Hay algunas lentes fáquicas que se colocan en la cámara anterior, pero estas tenían problemas y eran visibles en el ojo (ya que estaban frente al iris). Las más comunes, como la Visian ICL, se colocan en la cámara posterior. Es un procedimiento relativamente menor implantar o extraer una lente de este tipo. Sin embargo, pueden aumentar el riesgo de cataratas prematuras, especialmente si no hay suficiente espacio entre la ICL y el cristalino natural.
Ouch. I didn't know there was an anterior chamber in front of the iris and thought that the posterior chamber was behind everything. Sometimes it's GOOD to look at a diagram, isn't it? :-(
Any ideas about what might be causing my light streaks/beams?
¿Cuánto tiempo hace que fue su cirugía?
April 2015. I just noticed this a couple of months ago, but it might have been there all along and I just didn't notice it.
Un año y medio después, no podemos decir que aún te estés recuperando de la cirugía 
. ¿Te has sometido a alguna cirugía previa en ese ojo, quizá una iridotomía periférica? ¿Hay algún otro problema con ese ojo? ¿Persisten las rayas si sigues mirando la fuente de luz? ¿Hay algún problema cuando estás en una habitación oscura (por ejemplo, mirando un reloj despertador en un dormitorio oscuro)?
No other surgery. No issues. High pressure, but not yet glaucoma, and I'm using drops twice a day. Slight dry MD, but no changes in that since I first noticed it maybe 5 years ago. The light has to be a certain brightness, and the streak persists as long as I'm looking at it. No light/dark problems. I've got a retinologist that I'm going to see in 3 months or so -- he's taken a lot of pictures over the ~5 years that the MD has existed -- and he hasn't seen anything interesting in all that time.
¿Hay alguna diferencia en el fenómeno del destello si estás en una habitación oscura frente a una habitación brillante (es decir, ¿tu tamaño de pupila hace alguna diferencia)?
No, just that the contrast between the streak and the dark background makes it easier to see the streak. I just looked very closely at one of the curly light bulbs which has a sort of darker band in the middle. The streak duplicated the bulb lightness and darkness exactly. AND it's always at the same 45-degree angle.
Me pregunto si podría ser algún tipo de reflejo en la lente. Podrías consultar a un oftalmólogo diferente, ya que tu cirujano no sabe. Si lo haces, por favor, publica de nuevo y dinos qué dice él o ella.
The Costco optometrist who fitted me for contacts thought it might be some sort of reflection from the lens edge, in which case there's nothing that can be done anyway. I'm going to the retinologist in a few months and will post again then.
I'm really tired of being WEIRD!
Un cirujano refractivo diferente podría tener una mejor idea de lo que es.
Oye, todos somos raros, solo de diferentes maneras.
I have a similar issue. Did this ever get resolved for you?
