Blindness Can Be Caused by Smoking

August 18th, 2010 by andrewcaster

LasikDr. Andrew Caster would like to inform people about age-related macular degeneration. (AMD) Age related macular degeneration is one of the most common causes of blindness in adults in the United States, affecting more than 1.75 million Americans. While some risk factors for AMD, such as cardiovascular disease and hypertension, are well known, recent studies indicate that smoking appears to have a significant impact on an individual’s chances of developing the condition.
In an editorial, the BMJ (British Medical Journal) cited studies finding that greater than 25% of all cases of AMD with visual impairment or blindness can be attributed to current or past smoking exposure, making it the leading modifiable risk factor for the condition.The editorial considered multiple studies conducted worldwide that evaluated the correlation between smoking habits and the eventual development of AMD, which involves degradation and eventual loss of central vision.
Treatment of AMD remains limited. Identifying and eliminating or reducing risk factors is currently the primary mode of prevention.
The analysis focused on data collected from 12,468 patients in 3 cross-sectional studies that indicated current smokers were 3-4x more likely to develop AMD as were men and women who had never smoked. By comparison, smokers are 1.6x as likely to develop ischemic heart disease as nonsmokers — about half the risk or less of developing AMD – although the association between ischemic heart disease and smoking is much more recognized.
In three additional and separate studies of AMD in smokers and non-smokers in North America, Australia and Europe, smoking emerged as the strongest environmental risk factor for developing the condition. Studies also revealed that smokers developed AMD about a decade earlier than nonsmokers.
The good news: Smoking cessation appears to have a positive effect, decreasing the risk of developing AMD over time. Despite the clear evidence supporting the correlation between smoking and the risk of AMD, the researchers also noted that public awareness of the link is lacking and added that physicians and other health-care professionals are in a prime positions to educate patients about the very real vision-related risks of smoking and visual impairment.
Andrew Caster MD agrees that one should be aware of how other behaviors may harm the vision. Staying cautious and keeping healthy habits may benefits ones eyesight or better their chances of being a candidate for Lasik or other laser vision correction Beverly Hills Procedures.

The Benefits of Lasik Eye Surgery

July 29th, 2010 by andrewcaster

Lasik has an incredibly high success rate, and many more people opt to have Lasik every year. Even in this bad economy the price of Lasik goes up more every year. Some people may fear having a surgeon poke and proud in ones eyes but the fact is that surgery is known to last twenty minutes at most. Besides the procedure being very short most patients and surgeons agree that the only thing felt during the surgery is a bit of pressure on the eye as if someone was pushing down on their eye. During the surgery the surgeon will add numbing drops to the eye and have it held open with two prong like devices and it should be more or less painless, however doctor Andrew caster MD says patients complain of feeling a bit of an uncomfortable feeling but generally no pain and the procedure is always done faster than the patient expected. Apart from Lasik being a very simple surgery with minimal risk because of new technology it also has great benefits including:

  • Freedom- Studies have shown that most Laser vision correction Beverly Hills patients have 20/20 to 20/40 vision, this is enough to eliminate the worry of losing or breaking glasses and having to fill expensive contact prescriptions. Although Lasik is a costly option after some time of filling contact prescriptions the amount of money spent is the same. One does not have to worry about things like swimming or golfing with the worry of glasses or contact there eyes will be free and clear.
  • Immediate results- Most patients can see a vast amount of difference in their eyesight immediately following surgery. The patients eyesight will continue to improve every day as they heal.
  • Quick procedure-As I mentioned above the procedure is safe and quick. Most surgeons say it last the duration of fifteen minutes.
  • Improved confidence- Many Beverly Hills Lasik patients say after their Lasik surgery they experience everything feeling a completely new away about it. Surveys and research have shown that seeing clearly can make a person more outgoing and comfortable in social situations boosting their confidence levels.

Lasik is not the only laser vision correction procedure that can have great results. Some may not qualify for Lasik due to weak and fragile corneas or extreme dry eyes and for those there are other procedures that can be done for the same great results. If one is not candidate to have a laser correction procedure he or she should look into implantable contacts, which also has a great success rates and several benefits.
