The history of the excimer laser

The excimer laser was developed at IBM in 1976, and used to etch computer microchips. Its extreme precision with negligible damage to adjacent tissue made it a very attractive tool for other applications and in 1983 Stephen L. Trokel, M.D. in cooperation with R. Srinivasa, a physicist, applied it to corneal tissue in a New York Laboratory. The first sighted eye was treated with the excimer laser at LSU in January of 1987. Between 1987 and 1995 numerous laser manufacturers including VISX and Summit Technolog...

How long does the LASIK procedure take?

LASIK takes about 4 minutes for each eye. You will be in the laser suite for only 10 to 15 minutes if both eyes are being treated. Plan to arrive at the Laser Center for about an hour before the procedure to complete paperwork and any testing that may be needed. You will need a driver to take you home.

The best LASIK surgeon

Your regular ophthalmologist may be able to refer a good LASIK surgeon. You may also be able to find a list of surgeons in your local or online Yellow Pages. The U.S. Food and Drug Administration also offer a variety of links on their resource page ( that could be useful in locating a credible surgeon in your region. Any respectable eye surgeon will be happy to provide you with references.

To get a tattoo during pregnancy

Tattoos are not recommended during pregnancy. First of all, if the equipment isn't properly sterilized, there's a risk of transmitting blood-borne infections such as hepatitis B, hepatitis C, and HIV. In addition, your skin changes during pregnancy, and that may change the way the tattoo looks after you deliver the baby.

To get a seaweed wrap when I’m pregnant

If you get a wrap, don't get dehydrated or overheated in the process. Dehydration can lead to increased uterine activity and contractions; these won't change the cervix or trigger labor, but they can make you very nervous. So make sure to drink plenty of water prior to, during, and after the procedure. More important, being overheated can make you pass out. And getting overheated early in your pregnancy can slightly increase the risk of neural tube defects. Unfortunately, the damage occurs within 23 days of...

To get a perm while I’m pregnant

To get a perm while I'm pregnantWe've all seen pregnant hairdressers working in the salon and they seem to do okay. It's not so much that getting the perm is a problem for health reasons. It's that your hair isn't going to respond in a predictable manner when you're pregnant. The hormones of pregnancy change the composition and texture of your hair. So the perm may or may not hold. What little evidence there is indicates that getting a perm or chemically straightening your hair is no cause for concern. The fumes might be annoying, but the...

To get a mud bath during pregnancy

We don't allow pregnant women to get into the mud because the temperature of the mud is usually about 103 degrees and you're in for roughly ten minutes. That will raise your basal body temperature and speed up your metabolism, which can potentially be harmful to the fetus. There have been times when people have come in not knowing they were pregnant and had a mud bath and to our knowledge suffered no harmful effect. But we'd rather not subject a fetus to any potential risk.

Getting facial when I’m pregnant

As far as I know, as long as you tell the person performing your facial that you are pregnant, everything is fine. With everything that is going on in your body right now, you should tell EVERYONE who does anything to/with your body you are pregnant. Working is spas for 11 years, I am still amazed at how many people do NOT tell the technician. Luckily, most good techs will ask. At home, I have been using Origins Organic product line. I have found that with the increased oil production in my face, the mint w...

Diet during pregnancy

I don't recommend it — pregnancy is not the time to diet. Normally, you should gain about 25 to 30 pounds during pregnancy. If you're overweight, you may want to shoot for the lower end of that range. The recommendation for women who are morbidly obese is to gain only 15 pounds. Some gain is inevitable given the weight of the baby, the enlarged uterus, the placenta, and the amniotic fluid. But that's weight that should disappear quickly once the baby is born. On average you should be getting about 2,500 cal...

Getting Botox treatments during pregnancy

Getting Botox treatments during pregnancyBotox use by pregnant women has not been studied. If you've used Botox and just found out you are pregnant, it's unlikely there's any risk to your baby. Studies have shown that when Botox is injected into facial muscles, the small amount used is not expected to circulate throughout your body. Therefore it wouldn't get to your baby. If you're pregnant and are considering Botox injections, though, due to the lack of data, I recommend waiting until after you deliver your baby to receive the treatment.

Bleaching my teeth during pregnancy

Bleaching my teeth during pregnancyWe don't have any evidence that bleaching your teeth will pose a significant risk to you or your baby. But we don't have enough data to say it's safe, either. The peroxide used in bleaching causes an oxidative process, and we know that oxidation can be harmful to tissues and cells. But we don't know whether that can affect either you or your baby. There's another whitening process called microabrasion that uses acidic components to remove stains, but we have even less data on the safety of that in pregnancy...

The simplest and most reliable application or method for editing digital photo EXIF data

I got following question from somebody. I have a photo that was taken in 2006 and for some reason the EXIF 'date taken' value has been modified to a date in 2011. Being a Virgo I need order, and this goes to the extent of having ALL of my photos correctly sorted by date in Picasa!I've heard that some freeware EXIF editors can cause conflicts with other applications. Does anyone know of a reliable editor that will allow me to change the 'date taken' value without compromising the other data and without me ha...

Vibrating chair during pregnancy

The baby is completely wrapped in blood, bone, and fluid, which keep it well protected. To your baby, if you sit in a vibrating chair, it's no different than if you were to run up and down the street. So the massage is usually okay during pregnancy, but not on your hands or feet. If you get too deep of a massage on either it can cause you to have contractions. I read this in a pregnancy book. Make sure to always ask your obgyn before any questionable activity.

Heating pad for sore muscles during pregnancy

Using a heating pad while you're pregnant is safe. When applied to a specific area of the body, a heating pad can provide relief without raising your core body temperature. If your core temperature gets elevated early on in pregnancy, it can increase the risk of neural tube defects such as spina bifida. This is why women are advised to avoid hot tubs and saunas while pregnant. Pain can be a sign of potentially serious complications, such as a detached placenta or a uterine rupture, so alert your doctor if y...

Vision-correction surgery during pregnancy

LASIK eye surgery during pregnancy is not advised. Perhaps the most important issue is that your prescription sometimes changes during pregnancy. This is thought to be due to hormonal alterations that make the body retain more fluid, causing a swelling of the lens inside the eye. So you may get a little more nearsighted or develop more astigmatism as long as your hormones are elevated. Don't forget that your hormones remain elevated even after the birth of your child if you breastfeed. Another problem is th...
