What is Phacoemulsification?\n\nPhacoemulsification(PHACO) has gained in popularity in recent years, and is now the preferred form of cataract removal. Although this procedure has been available to us for a long time, recent advances and refinements in machine and microsurgical instruments have made it safer and more effective than previously.\n\nThe technique of phacoemulsification utilizes a small incision. The tip of the instrument is introduced into the eye through this small incision. Localized high frequency waves are generated through this tip to break the cataract into very minute fragments and pieces, which are then sucked out through the same tip in a controlled manner. A thin 'capsule' or shell is left behind after cleaning up of the entire opaque cataract.\n\nThe incision size for phacoemulsification is approximately 3.0 millimeters in width. If a lens implant that can be folded is used following removal of the cataract, this incision may not have to be enlarged. If a lens is used which cannot be folded, the incision must be enlarged to 5.0 or 5.5 mm.\n\nAre the stitches required after Phacoemulsification?\n\nThe incision (wound) required for phacoemulsification is small (3 mm) and the wound construction is such that it is self-sealing. Therefore a surgery in which a foldable lens has been implanted through the small 3 mm wound, generally does not require any stitch, as it is watertight. The surgeries in which the wound has been enlarged (5 or 5.5 mm) to put a lens that can not be folded, is likely to require one stitch, because the wound is larger.\n\nIn addition, some surgeons simply prefer the safety of having the incision sutured, even if the incision is already watertight. The best procedure for a patient is usually the one with which his or her ophthalmologist feels the most comfortable, since these variations of cataract surgery are all quite effective.\n\nWhat are the advantages of Phacoemulsification over routine extracapsular surgery?\n\nIn a conventional surgery the incision required is larger (10-12 mm) and requires stitches for closing. This larger incision takes 6-8 weeks to heal. Moreover, the stitches can cause distortion of the normal curvature of the cornea (the clear part of eye) and thus lead to astigmatism and blurred vision because of this.\n\nEssentially all the advantages of phacoemulsification are because of small incision, which is self-sealing. The wound is more stable and the chances of wound complications are minimized. The patients can resume their normal activity faster as compared to conventional extracapsular surgery. The wound healing is faster and more predictable, and therefore glasses can be prescribed much earlier as compared to the conventional surgery. The patient requires less follow up visits for checkups. As the incision is small and in many cases stitches are not required, the cornea does not get distorted and therefore the chances of significant astigmatism is mi

Your prescription is the power in diopters of your glasses.  No conversion necessary.  If you don't have your prescription, your eye doctor can use a special instrument to read the power of your glasses.

I suggest eye laser surgery. I had mine 5 years ago after wearing contacts for 20 years and it was the best money i ever spent. I understand that current technology even makes the procedure with instant results and no recovery time for a week like i had. And it is painless. Now if you dont like that option, remember that the eye is the most resilient organ in your body and heals the fastest when injured so there is no reason to be afraid to touch it. Once you get past that hurdle it should not take you long to learn to wear the lens...good luck

Laparoscopy is direct visualization of the peritoneal cavity, ovaries, outside of the tubes and uterus by using a laparoscopy. The laparoscopy is an instrument somewhat like a miniature telescope with a fiber optic system which brings light into the abdomen. It is about as big around as a fountain pen and twice as long. \n\nAn instrument to move the uterus during surgery will be placed in the vagina. Carbon dioxide (CO2) is put into the abdomen through a special needle that is inserted just below the navel. This gas helps to separate the organs inside the abdominal cavity, making it easier for the physician to see the reproductive organs during laparoscopy. The gas is removed at the end of the procedure.

Laser surgery is usually recommended for people with high myopia IE. -4 and above ie.,-8 or -12 etc.\nHowever if a person feels his beauty is getting impaired by glasses and discomfiture using a contact lens he may opt for a laser surgery. A fine laser vaporises a thin layer of cornea so that the light is made to bend at appropriate angle and is made to focus on the retina.\nThe procedure is painless and in done in stages\n\nLaser urgery if done under sterile conditions and by a experienced optholmologist should cause less problem

Quoting from Divers Alert Network Europe, under the "Research/Medicine" heading:\n\nLASER EYE SURGERY\n\nQuestion:\nI have a question about eye surgery. \nIs there any difference in waiting time before returning to diving when the laser eye surgery is done by PRK-METHOD?\n\nAnswer:\nIn general laser corneal surgery is considered to require a return-to-dive interval ranging from 2 until 4 weeks, depending on the type of surgery, Lasik techniques being the ones requiring less time.\nSurgical radial keratotomy interventions require a longer interval, generally not less than 3 months.\nThere is no known permanent contraindication to resuming diving when clinical complete healing is achieved after non complicated eye surgery performed with such methods, unless other conditions, ocular or general, may be present.

I believe that it is possible.  However, you can't have any laser eye surgery.  If you have Lasik which is popular now they will not let you.  You must get PKG, sometimes called bladeless lasik.  The military actually pays for this surgery and performs it at Bethesda on the East Coast, somewhere else on the west.  The difference is that in lasik the cornea is cut and then reattached after the lasering.  Because of the pressures on the eye during flying this can actually open back up.  In PKG they rub the cornea off before lasering.  They then allow the cornea to heal itself underneath a contact lens.  This method is actually safer and has less side effects.  The reason that Lasik is so much more popular is that the healing time is only a matter of hours, whereas it is about a week for PKG.  I suggest doing a lot of research and do not talk to a recruiter, they won't know what they are talking about.  Talk to an admissions officer for the Air Force Aceademy, they will have a better idea.

I also had the surgery about 6 years ago now, so I imagine that technology has greatly improved since then. I really didn't experience any pain with the procedure, but it was a little weird. It worked great and is still working. Usually they tell you you can't do certain things for like a month afterwards while your eye heals up completely, but I suppose it depends on what type of surgery you are getting (they have different kinds now.) I'd say go for it. It's great not to have to wear glasses or contacts.

My father had lasik surgery on both of his eyes (Cleveland clinic) and since then he has had perfect vision, would i recommend it?  Due to the fact that it is no longer that new of a technique it isn't as expensive as it used to be when lasik first came out.  If you have the money...my advice is to go for it!  ...It does not ruin the kidneys...if you want some factual advice talk to your Doctor or look it up on the Internet.

I wore contact lenses for 31 1/2 years and tri-focal glasses for 10 years.  My vision was 20/1000!!!!! I had lasik surgery last September and found it to be a miracle!!!! My vision is 20/25 and I can read things I was not able to read since I was a small child!  There are NO aftereffects whatsoever.  This procedure does not last a lifetime, and will necessitate further procedures (depending on the original-blade or bladeless surgery) and maybe that is where the silliness of causing blindness in old age comes from.  I would SERIOUSLY consider a consultation.  They are usually free and will answer all of the questions YOU have.  In the long run, it is a small price to pay for sight!

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

I would strongly recommend you and your friend to read this website carefully before making a decision. You have only one pair of eyes, and therefore should not risk your most precious things. I have had lasik surgery myself, and if I were given a choice , I would never have it again. Please do not believe in those who can benefit from your surgery. What they aim at is money, and not your health. I think there is a new technique that helps shape your eyes and thus reduces your myopia without involving any operations at all.\n\nUseful website:\n\nhttp://www.lasikdisaster.com/
