According to the Canadian Ophthalmology Society (COS), 1.5 million people have cataract surgery in North America each year, and a routine eye exam is the best way to know for sure whether changes in your vision are being caused by cataracts.
As we get older, the clear lenses in our eyes not only become more rigid, but they also become cloudy. Although cataracts normally occur with age, there are instances when younger patients and even children can develop a cataract. Diabetes, trauma to the eye, and certain medications like steroids can also be associated with cataracts.
The clear lens in our eyes allows light to pass through to the retina, and our brains then decipher the images. As the lens becomes cloudy, no light can enter or pass through, and your vision is obstructed. It would be similar to attempting to look through a very dirty window.
The Slow Vision Thief
Most cataracts develop slowly. Vision gradually becomes impaired and sometimes patients don’t even realize it is happening. They just think that they are getting old and there is nothing that can be done. That is why having routine eye exams is a good habit to develop. The physicians at OCC LASIK can diagnose the early stages of a cataract and recommend when might be the best time to remove it.
Common Symptoms of Cataracts
Ironically, the earliest signs of cataracts are sometimes a change in vision for the better. If you are farsighted or have presbyopia, you will suddenly become nearsighted and not need your reading glasses for a time. If you are nearsighted, you may become more nearsighted and your distance vision will decrease. Other signs include:
- Glare
- Difficulty driving especially at night
- Blurred vision or double vision
- Frequent changes in prescription
Advanced Outpatient Surgery
Once it has been determined that a cataract needs to be removed, the surgery is performed as an outpatient procedure and is usually completed in less than an hour. The physicians at OCC LASIK use the Catalys Femtosecond Laser, which breaks up the cataract lens using less energy than the older technologies. It is the most sophisticated cataract laser system available making it more accurate and safer than ever before. Once the cloudy lens is removed, the new permanent artificial intraocular lens (IOL) is precisely implanted. Simple monofocal IOLs and multifocal lenses are available. Based on your visual needs and lifestyle, your doctor will recommend the best option for you.
If you suspect that you or your parent may have a cataract, contact the physicians at OCC LASIK.
