    What is an angioplasty, stent or coronary intervention?

    After a diagnostic angiogram is performed, there are several possibilities. If there are no or mild blockages, medical therapy is advised and the procedure is complete. If there are numerous blockages, a blockage in unfavorable locations, or abnormal heart valves, a heart operation (bypass surgery or valve surgery) is advised. If there are blockages which are amenable to angioplasty then that procedure is usually performed immediately after the diagnostic angiogram. Angioplasty is a procedure where a catheter with a small balloon at the tip is inserted at the site of a blockage. The balloon is properly sized and then inflated to open the blocked artery. The balloon catheter is then removed from the body. This procedure is rarely performed by itself in 2005 due to an increased chance of a recurrence (restenosis) 3-6 months after the procedure. New metal devices called stents are utilized in over 90% of intervention procedures. The newest generation of stents which are permanently implanted metal coils coated with medications which inhibit restenosis are used in a majority of cases. The chance of a regrowth of the blockage after a medication coated stent is placed is under 5%. An intervention procedure usually requires at least a one night stay in the hospital.

    What is Astigmatism? How is Astigmatism corrected?

    Astigmatism is a refractive error usually associated with an irregularly shaped cornea. A spherical cornea creates a single focal point while an astigmatic, irregularly shaped cornea creates more than one point of focus. As a result the image that is formed on the retina of the eye is blurred. Glasses, contact lenses and refractive surgery may all be used to correct Astigmatism.

    What is involved in a hearing evaluation?

    The first step in a hearing evaluation will be a detailed case history regarding your hearing health. Your answers, as well as any additional information, will provide valuable background information. Next, a diagnostic hearing evaluation will take place using listening and measurement devices. After testing is complete, your audiologist will review the results. If a medical condition is discovered or suspected, you will be referred to a medical doctor for treatment and consultation. If the test results indicate you would benefit from the use of hearing instruments, various options most appropriate for your hearing needs will be discussed.

    Are statins safe?

    Statins, also known as HMG-CoA reductase inhibitors, are highly effective cholesterol-lowering medications. Statins have been studied extensively and overall have been proven to decrease the risk of heart attack, stroke, and other coronary artery diseases that are related to high cholesterol levels Statins have been around for 20 years, and their safety record is convincing. It’s true that nobody knows about the very long-term side effects, which could take decades to show up. But from what we know now, the rare adverse effects are far outweighed by the lifesaving benefits. And, if anything, the studies pointing to potential additional benefits (prolonging life) seem stronger than those suggesting additional adverse effects.

    What is the difference between an Optometrist, Ophthalmologist and Optician?

    An Optician is involved in the fitting and making of eyeglasses. Optometrists and Ophthalmologists are both eye doctors who diagnose and treat various vision conditions and eye diseases. The main difference between an Optometrist and Ophthalmologist is that an Ophthalmologist is also trained to do eye surgery.
