Timothy Quinn, M.D. – Ophthalmology
Cataract Awareness Month is a great time to step up in helping to educate and drive people to seek treatment for one of the leading causes of vision loss and blindness in the United States. 1According to a Prevent Blindness® study, nearly 25.7 million Americans ages 40 and older have cataract and the number will increase by 50 percent to 38.5 million by 2032 and by 78 percent to 45.6 million by the year 2050. Cataract is a clouding of the eye lens that commonly leads to reduced contrast and color due to less light being able to reach the retina. “Patients may notice decreased night vision or needing more light to read,” says Timothy Quinn, MD, Board Certified Ophthalmologist at Physicians Regional Medical Group. “Cataracts eventually cause blurring, but this is fairly late in the course.”
Most cataracts are a normal part of aging and the risk increases as you get older. Dr. Quinn states that only 1% of his cataract surgeries are performed on patients below 60 years of age. This does not mean that those younger than 60 are exempt. 2The National Eye Institute lists four other types of cataract to include:
• Secondary cataract. Cataracts can form after surgery for other eye problems, such as glaucoma. Cataracts also can develop in people who have other health problems, such as diabetes. Cataracts are sometimes linked to steroid use.
• Traumatic cataract. Cataracts can develop after an eye injury, sometimes years later.
• Congenital cataract. Some babies are born with cataracts or develop them in childhood, often in both eyes. These cataracts may be so small that they do not affect vision. If they do, the lenses may need to be removed.
• Radiation cataract. Cataracts can develop after exposure to some types of radiation.
For most, cataracts develop slowly and don’t disrupt the vision early on. “In many cases, it is not noticed until after cataract surgery when there is a great increase in brightness and color,” explains Dr. Quinn. While there is no prevention for cataracts, Dr. Quinn mentions that certain personal behaviors have been shown to slow the progress of cataracts. These include wearing ultraviolet protection, avoiding tobacco products, and maintaining a healthy blood sugar.
Cataracts are commonly detected through a visual acuity test, a dilated eye exam, or through a measurement of pressure inside the eye. Dr. Quinn’s diagnostic tests also include a clinical exam that measures the opacity in the lens of the eye. He notes that grading its severity can be a challenge as it does not always correlate to symptoms. He points to the effectiveness of performing a wavefront analysis with machines like the iTracetm that are very instructive in measuring both the dimming and blurring effects of cataracts.
If prescription glasses aren’t enough to improve vision impairment caused by cataracts, the only effective treatment involves simple surgery where the clouded lens is removed and replaced with a clear artificial lens. “Fortunately, innovations in equipment and surgical technique have made the procedure safer and more effective for most patients,” says Dr. Quinn. “The vast majority of patients will do well with surgical techniques and lenses that are covered by their insurance. “
Cataracts can be easily diagnosed and visiting your eye doctor regularly is important in helping protect your eyes from further damage. The American Optometric Association recommends annual eye exams for everyone over the age of 60, and bi-annual exams for adults between 41-60 years to check for developing eye or vision problems.
