bladeless lasik eye surgery performed by Dr. Swati Singh at Laservue eye center in San Francisco compare the video of this new intralase tecnology for flap creation to the other videos on this site. this way is much safer and (only) about $400 more per eye. -Flap is made with new intralase technology. microscopic bubbles created at a certain depth into the cornea which is then easily pealed back. -Then the flap is flipped back and cleaned. -Next comes the laser correction followed by another cleaning and the flap is flipped back on. -Healing process begins imediately. patient: Evan Roth age: 20 Laser: VISX STAR S4 (Dr. Swati Singh has performed over 10000 surgeries since her board certification in 1999. give them a call and tell them Sean sent you… haha) www.laservue.com 707-522-6200 800-527-3745 (low quality video because it was filmed with my digital camera)
A person that is considering a Lasik procedure to improve their vision has two major responsibilities: selecting the best surgeon possible for their budget, and understanding and keeping up with eye care after the Lasik operation is done. Most Lasik procedures go very smoothly, and more than 90% of the patients are happy with their improved vision and have no permanent side effects. Part of this success is due to good care at home once the Lasik procedure is complete.
The first step in having the best care after a Lasik procedure is to understand exactly what is directed by the Lasik physician. The prospective Lasik patient should be given a good understanding of the entire process when they first visit a Lasik center to interview the physician and the staff. On the day of the procedure, a member of the staff should very carefully go over exactly what steps should be done to encourage optimal eye health and healing after the Lasik operation.
One thing that the patient should ask is what side effects are to be expected directly after the Lasik procedure, how long they should last, and which symptoms should be promptly told to the Lasik physician or member of the staff. A number of symptoms, such as fluctuating vision or halos around lights, are to be expected and are not a cause of worry. Ask the staff about any postoperative symptoms that are unclear, to make sure that they are thoroughly understood.
Each Lasik physician has their own recommended procedures for their patients, but here is a list of typical suggestions that most Lasik centers recommend. First, get some sleep as soon as possible after the Lasik procedure is done. This gives a great boost to the healing process. Second, avoid any contact, bumping, or rubbing of the eyes for at least five days after the Lasik procedure. Most Lasik centers have some kind of eye guards to wear at night to prevent patients from rubbing their eyes in their sleep.
Third, try to avoid eyestrain for some days after the Lasik procedure. It is tempting to try to read all of the signs and words that were previously blurry, but avoid this temptation at least for the large part. If any light sensitivity or glare is noticed, wear dark sunglasses for several days until this problem resolves itself. Some common Lasik side effects are temporary halos around lights, especially when viewed at night, but this is not a problem to be concerned with.
It is very important to keep the eyes well lubricated in the days following a Lasik operation. Every Lasik physician will give eye drops to help this, and patient should be especially aware of this before going to sleep. A Lasik procedure may increase eye dryness temporarily, and during sleep this may make the eyelid stick slightly to the eye. When the patient wakes up, opening the eyelid is equivalent to rubbing the eye. The physician should be notified if this happens, for there are other varieties of eye drops that will solve this problem.
Taking these simple steps will give nearly all Lasik patients an easy postoperative experience without any problems.

A Conversation with Ivan Seidenberg
(Glass bangs.) ALAN MURRAY: Thank you, whoever helpfully banged their glass. Welcome to today’s Council on Foreign Relations meeting, part of the CEO Speakers series. Everybody please turn off — well, two requests.
I’ve been wondering about Lasik, but I’m really squeemish with my eyes; I can’t even put contacts in because it freaks me out so much. So here’s my question: Can you be anesthetized during Lasik?
I haven’t even decided if I want to have it done, and if I do, it won’t be done anytime soon.
I just want to know if I should keep considering it.
The number of individuals who need vision correction is still on the increase across the globe. Eyeglasses with vision correction function have been an indispensable part of daily lives for many people. Some individuals may have difficulty in reading newspapers or deciphering symbols on a traffic sign without the help of corrective lenses. Even if they have an inherent need for eyeglasses, these people may not know how these glasses are made.
I have noticed that more people I work with are talking about, or undergoing, the Lasik vision correction procedure. I don’t know really know why Lasik has suddenly become more popular in my company, but I do know that there are a number of rumors about Lasik that I am not sure are true. Let me just talk about my long term experience with Lasik.
It has been more than eight years since I had the Lasik procedure, so I was one of the early and brave pioneers! Perhaps I wasn’t that brave when considering Lasik, for my vision in each eye was worse than -9. Even now, Lasik physicians consider that a very strong case and do caution prospective clients that the Lasik process will likely improve their vision, but may not eliminate the total need for glasses.
The Lasik operation itself had mild pressure and some unusual feelings, but no real discomfort or pain. This is still true in modern Lasik procedures, and hopefully they are even better at keeping the client comfortable. I do notice that now Lasik physicians also give a mild sedative mainly for psychological reasons, which I think I would have appreciated back then.
Two or three days after the Lasik operation I was astounded to find I had VERY clear vision in each eye, at least 20/20. Considering my previous prescription, you can imagine how fervently I thanked my Lasik physician. However, I did also have temporary symptoms of considerable dryness in each eye (which was helped by eye drops), and also halos around lights at night.
A few months after the Lasik procedure I noticed my vision changing a bit, though very slightly. The best way I can describe it is that the crisp edges no longer looked exceedingly crisp, but each object still seemed to be in focus. At my one year Lasik correction anniversary my physician said that one eye was still at 20/20, but the other had changed slightly to 20/40. However, I was still a great statistic for the Lasik correction procedure, and we were both still happy with the results.
In the years between the original Lasik procedure and now, my vision is still 20/20 in one eye and 20/40 in the other. I do have a pair of glasses and one contact lens for that eye, but rarely bother with them unless I am doing something like watching a movie. My long track record after the Lasik procedure has given hope to a number of other people in my office. I do want to say though that I was over 35 when I had the operation, and my Lasik physician said that the stability of my eyes and my age were good indicators that the Lasik results would be long term.
I hope this encourages people with bad vision to talk to a local Lasik physician about scheduling a Lasik procedure. Find a physician that has a good track record, and one that you trust, and I hope that your long term Lasik results will be as good as mine!

Let’s walk through what a client experiences when attending a Lasik center for a Wavefront Lasik procedure. The procedure itself generally only takes between five and ten minutes for each eye in total, and both eyes are done during the same procedure. The actual time to reshape the eye with the Lasik excimer laser is usually less than 15 seconds per eye.
Any person’s vision problems are generated by small “aberrations” within the eye that prevents the light from focusing objects as they should. The Lasik equipment locates and classifies these aberrations and then processes them so that the Lasik physician will correct these and allow the light to focus properly once the eye has healed.
In a Wavefront Lasik procedure, the patient stares at one point while a light is sent into the eye, which is reflected back and read by a Lasik Wavefront sensor. The distortions in this reflected light are mapped using a small computer within the Lasik system, and then this information is used to guide the laser that treats the eye.
Once the light creates the map for the eye, the Lasik surgeon has to create a small flap to access the cornea. This is done using a laser (this type of Lasik procedure is known as IntraLasik, or bladeless Lasik) or a small blade known as a microkeratome.
This flap is then opened to allow the cornea to be reshaped by the Lasik system.The excimer laser actually reshapes the cornea, which is the crucial part of the Lasik procedure. In order to determine exactly how to reshape it, the map created earlier by the Wavefront sensor is used to direct the beam of light accurately. The Lasik physician uses these precise tools to get the clearest vision results possible.
This custom Lasik procedure can not only correct such standard problems as nearsightedness, but can also address aberrations that create light halos, glare, haze, or starburst patterns. Once the Lasik physician determines that all relevant aberrations have been eliminated, he replaces the flap in its proper position, where it adheres normally and will heal naturally.
As mentioned earlier, this entire Lasik process takes between ten and fifteen minutes per eye. A patient gets a mild sedative and eye numbing drops to make the procedure both relaxing and painless. Most people notice an improvement in vision due to Lasik almost immediately.
Once the Lasik procedure is finished, you will get some eye drop medication to lubricate and protect your eyes. This medication (and the liquid in the drops themselves) may cause some blurring, and so for this reason (and to avoid any eyestrain) you should arrange for someone else to drive you home. It is also a good idea to go to sleep as soon as possible after the Lasik operation in order to promote even faster healing.
To promote optimal healing the Lasik physician often gives a plastic shield to wear over your eyes for the first night or two. Follow closely any recommendations by the Lasik physician. Do further investigation into this great new Lasik procedure, and get a clearer focus on your future!

Most people take their vision for granted, especially if they have never suffered from poor vision. For many, there is no other option except for eye surgery. Other people choose corrective surgery because they are tired of always having to use eyeglasses. As you start looking into your eye surgery options, you will find that there are many new techniques that are used in corrective vision surgery. How do you choose the right procedure? What are the differences between LASIK surgery and the new Epi-LASIK surgery?
The Difference between LASIK and Epi-LASIK Surgery
Epi-LASIK and LASIK surgery are different procedures for corrective eye surgery. These procedures reduce or eliminate a person’s need for glasses or contact lenses. Up until recently, the usual procedure for eye corrective surgery was LASIK surgery. LASIK surgery stands for Laser Assisted In Situ Keratomileusis, and this procedure basically changes the shape of the eye’s cornea using a laser. During the procedure, a flap is cut in the cornea, and then this flap is folded back to reveal the middle section of the cornea. The laser then changes the shape of the cornea and the flap is then replaced.
Epi-LASIK surgery is also an eye corrective procedure that has evolved from LASIK surgery. It has combined the best elements of LASIK, LASEK and PRK procedures into one. It involves the separation of the epithelial from the top of the cornea, and this eliminates the need to cut into the cornea and create a hinged flap. As opposed to LASIK surgery, Epi-LASIK combines surface based procedures that do not need the flap procedure and the advantages of LASIK surgery, which produce less pain and faster recovery.
Epi-LASIK surgery is still similar to the LASIK technique because it still involves the use of a laser beam to reshape the cornea. It appears to be more effective with people who suffer from mild forms of farsightedness, astigmatism or nearsightedness. If a patient suffers from moderate to severe myopia, then LASIK surgery is still the best option.
Why is Epi-LASIK Surgery Better Than PRK and LASIK Surgery in Some Cases?
Epi-LASIK came about because of certain complications with PRK and LASIK techniques.
• PRK created a large abrasion when removing the epithelial cells and this would cause the patient discomfort. Plus, the procedure caused some haze in the cornea which created haloes around lights. These effects lessened after six months, but were still uncomfortable during that time period.
• LASIK creates a hinged flap, which is not really painful. However, it created other problems caused by the flap, problems such as dry eyes or scratchiness.
Epi-LASIK then tries to avoid the problems associated by both procedures by combining the advantages of surface based procedures that require no flap and the advantages of LASIK that provides less pain and a faster recovery. In essence, Epi-LASIK surgery gives you a shorter visual recovery time and reduces the risk of any complications.
Who does Epi-LASIK surgery benefit?
Studies have shown that people with thin corneas benefit more from this type of surgery, because LASIK surgery requires more corneal tissue in order to create the flap, and these patients don’t have enough corneal tissue.
It is also shown to benefit people who risk having the flap dislodged. These people risk being hit in the face or the eye for any number of reasons, people like athletes or people who work in violent fields, like the military or police fields.
Who Benefits More from LASIK Surgery Rather than Epi-LASIK Surgery?
Patients who have moderate to severe myopia tend to benefit more from LASIK surgery rather than Epi-LASIK. Epi-LASIK suits people who do not have such steep corneas.
Each type of LASIK surgery has pros and cons and should be analyzed with your doctor. That way, you can find the best type of corrective LASIK for your specific needs. It is important that you talk about these issues and LASIK cost with your doctor before you undergo surgery.
