A cataract occurs when the normally clear lens of our eyes becomes hazy and yellow. The cataract affect our vision by causing blur, haloes, double vision, or inability to see without very bright light. Most cataracts occur as a natural aging process, and the lens starts to cloud as early as 40 years old. People with cataract see the world through a clouded window and daily activities become difficult. The glasses prescription often change as well with the development of cataracts.
Symptoms of Cataract
The following signs and symptoms typically include both eyes:
Naturally, cataracts occur gradually. You might not even be aware of their presence until they begin to obstruct light. Next, you could observe:
Most cataracts are brought on by age-related changes that are natural for your eyes.
Your eyes’ lenses are clear while you’re young. The proteins in your eye’s lens begin to deteriorate and clump together around age 40. This mass creates a cataract, a clouded region on your lens. As the cataract worsens over time, more of the lens becomes cloudy.
Cataracts have several underlying causes.
Among them is an excess of oxidants, which are oxygen molecules that have undergone chemical modification due to daily living.
Cataract eye surgery is very common and a medically necessary procedure. This surgery can be done in the traditional fashion to remove the cloudy lens and replace with a clear lens. Dr.Bala also uses advanced technology femtosecond laser to perform cataract surgery without a blade or knife. You may be a candidate for advanced lens options to help with your astigmatism, near sighted-ness or far sighted-ness.
Options for Cataract Surgery
There is no scientific evidence to support any methods for cataract prevention or progression. However, doctors believe that several ways, such as:
You will need glasses (possibly bifocals) for most or all activities. The intraocular lens can focus light at one distance, and does not correct any astigmatism.
You will likely be less dependent on glasses. The intraocular lens and surgical technique can help correct astigmatism, and offer range of vision.
A LASER (instead of a blade) does some of the steps of the surgery to increase precision and safety.
Cataract surgery procedure time: ~ 20-30 minutes
Recovery time: 2-20 days
Follow up visits required
Refractive lens exchange
This is a procedure for younger people, typically over the age of 40 years old who have pre-cataract changes and would like to improve their vision. Refractive lens exchange is a better option than LASIK for people who have age related lens changes as it provides a good solution to better quality vision.
