what is the origin of cockscomb gel used in eye surgery?

LOL, let's hope it's not what first comes to mind. :)

its just grease, used to be ash from corks, more recently people use strips probably like tape.  There's also temporary tatoo type eye-black which is an ink.

Try a slice of cucumber over each eye while soaking in a warm bath or while just relaxing in the evening.  You can also try a moisturizer or replenishing lotion such as Aveeno.

See clearly method. I think it's on emule too. It costs a lot and usually doesnt do anything, but always that chance.\n\n\nlasic surgery. it usually works beautifully but costs 2000$ for both eyes and in rare cases can leave them very sensitive.

The actual surgery doesn't hurt at all.  It may feel like you have a piece of sand in your eye for a couple of days afterwards.

This link is to the big company in that field that merged with the other early robotics for surgery company Computer Motion a few years ago. \nhttp://www.intuitivesurgical.com/index.aspx

Perhaps you should re-post this Q under 'Zoology' or 'Pets' in order to help you find appropriate answerer(s).\n\nIn all probabilities, it's most likely to be Sodium Hyaluronate. Try to find the sterilized package that contained the syringe, the details of the medication is usually printed on it.\n\n:o)

I never heard it called that before, but here's what I found:\n\nThe plica (PLY-ka) semilunaris (sem-ee-LOO-ner-is) is located around the eye. For many years, this organ was thought to have no function. But lo and behold, eventually it was discovered that this “useless” organ has an important function after all. \n\nIn fact, it is the “crusty” factory. It secretes a sticky mass that collects any foreign materials such as dust or pollen. All this trash is surrounded by the sticky gook so that it does not scratch the sensitive cornea in your eye. Once the garbage is collected, the plica semilunaris “escorts” it out of the eye just like a security guard would escort noisy troublemakers out of a theater.

I know this sounds wierd but my mom always made me do this when I had a stye. Rub a gold ring (real gold) on the eye it always helped me

Phacoemulsification ("phaco") was developed in the search for a way to extract cataracts through a smaller incision. It has become the preferred technique for cataract extraction. An ultrasound or laser probe is used to break the lens apart without harming the capsule. These fragments are then aspirated out of the eye. A foldable intraocular lens (IOL) is then introduced through the 3mm incision. Once inside the eye, the lens unfolds to take position inside the capsule. Patients are fully conscious during the procedure and can have surprisingly colourful visual experiences. No sutures are needed, as the incision is self-sealing. The risk of astigmatism and sudden pressure changes inside the eye are minimized. The procedure is safe enough to be done under topical anesthesia (anesthetic eyedrops). Visual rehabilitation is extremely fast and patients don't need to suspend their everyday activities.

It is a stye.  There are two types of styes.  They are internal and external styes also called hordeolum.  The external stye is the common type that people see along the follicle.  The internal type is less common that the external but still can be common, is found further back from the follicles.  The treatment is typically conservative.  DO NOT TAKE THE ADVICE OF SOME OF THESE PEOPLE ON HERE....DO NOT POP IT!!!  Simple warm wet compresses to the area for 20 min at a time 4-6 times a day will help to get rid of it.  Also some tylenol will help for the pain.  However, if it starts feeling like it is scratching the eye itself or if your vision starts to change then it would be a very good idea to go ahead and see your doctor.  Take care!

Yes.  Contact lenses (the soft ones), are made of a special hydrogel.  This allows the contact lens to sit on your eye daily without irritating it (I know they irritate a bit but trust me.. it could be much worse!).  This places them in the classification of biomaterials.  \n\nBiomaterials are materials that come into direct contact with the body but are not 'of the body' so to speak.  Whenever something that is alien to the body (and this includes non native organ donors), an immune system response will ocur.  This will lead to inflammation depending upon the extent of the immune response.\n\nThe extent of this inflammation depends upon how biocompatable we can make the material.  Hydrogels are what we call very hydrophilic.  That is that they bind very well with water (and are indeed mostly water which is very biocompatable).  Thats why they slip and slide and are a bugger to get in and out of your eye.  This enables them to sit on your eye with minimal immune response.\n\nHowever, over the course of the day bacteria and dirt binds with the lenses.  Soaking them over night in saline and treatment disinfects them.  If you don't disinfect them, bacteria and dirt in general triggers a bad immune response of inflamation.. hence the red eye syndrome everyone hates.  \n\nAlso, because they are hydrogel, over the course of the day they can dry out.  Blinking unfortunately is not sufficient to keep them hydrated.  As they dry out they shirnk a bit and become quite hard like a plastic almost.  You can see this if you leave an old lens to dry out on the side for a bit.  This further becomes an irritation as now, rather than having a very soft lens on your eye, you've got a lump of hard plastic.\n\nFinally, with them also being very hydrophilic, as they dry out they will try to absorb water into their matrix from your eye.  This creates (in short detail) a bond between your eye and the lens making them also difficult and uncomfortable to remove.\n\nSo to summarise, don't leave em in.  It can be uncomfortable and potentially hazzardous for infection.  Also keep em clean or use new ones daily!\n\nHope this helps.

It is used to - \nsupply zinc in animal feeds, fertilizers, and agricultural sprays. \n\nZnSO4·7H2O is used in making lithopone, \nin coagulation baths for rayon, \nin electrolytes for zinc plating, \nas a mordant in dyeing, \nas a preservative for skins and leather \nand in medicine as an astringent and emetic.\n\nZinc sulphate can be used in the eye as an astringent to relieve over production of tears. \n\nThey can be particularly useful in those suffering from eye infections, in which watery eyes can be a problem.

I work for an eye doctor.  We have been in contact almost every day with our Sales Rep from Bausch & Lomb (the company that makes ReNu).  They have advised us not to hand out the solution for the time being.  The Center for Disease Control is investigating the cases reported and trying to discover the cause.  They discovered that the infected patients have all been using the ReNu Solution, but no direct cause has been determined yet.  The CDC has NOT specifically accused B&L for the outbreak but have asked them to halt production and distribution for the time being.  This fungus is extremely rare and only about 50 actual cases of it have been reported.  I think it is important to note that ReNu has been using "Moisture Loc" in their solution for years.  The FDA never approved it until now so that's why they never advertised it and changed the labels on their bottles.  So the actuality of this particular solution causing the fungus is highly unlikely since the same solution has existed for several years now.  However, you should be cautious and proper contact lens care should be used when cleaning and handling your lenses.  Always wash your hands before putting them in and taking them out.  Always use a lens solution that has disinfecting properties.  Sterile saline cleans, but does not disinfect.  This particular fungus does cause permanant eye damage.  If you think you have symptoms, you should consult your eye doctor immediately.  Some symptoms include:\nSudden Vision Loss\nCloudiness\nRed and Irritated Eyes\nPain or Pressure\nAlso, if you are actually diagnosed, be sure that your doctor reports your case to the CDC and B&L.  Please pass this information along and encourage people to consult their eye doctors if they have questions.  Calling B&L directly is not effective and is not recommended.

Warm (NOT hot) compresses.  DO NOT try and pop it, it will go away on it's own.  If you are female, you MUST throw away all of your eye makeup.  I know that it's expensive, but it is now infected with the same bacteria that caused your sty, and it can reoccur if you don't replace it.  Basically, just wait for the sty to resolve itself...

Dr. Samuel Blum, invented the procedure used in LASIK eye surgery, which has restored vision to a lot of people..☺
