Blurry Vision But No Eye Pain: Understanding Cataract Diagnosis from Calgary Optometrists Near You
Cataracts refer to the clouding of the eye's natural lens, resulting in blurry vision or impaired vision. Unlike infectious or degenerative diseases, the reason that cataracts develop is age-related changes in the lens's structure and composition. Over time, proteins within the lens may clump together, causing opacity and interfering with the passage of light onto the retina. However, not all cataracts are the same. They vary in terms of their causes, symptoms, and impact on vision. Recognizing the symptoms of cataracts is crucial for early detection and timely intervention.Common Signs and
Symptoms of Cataracts:
Blurry Vision: Blurred or hazy vision is one of the hallmark symptoms of cataracts. Individuals with cataracts may notice a gradual deterioration in their ability to see clearly, especially at night or in low-light conditions. This is often diagnosed in an eye clinic by using the eye exam chart.
Difficulty Seeing in Bright Light: Cataracts can increase sensitivity to bright lights, causing glare or halos around light sources. This can make activities such as driving at night or reading under bright lights challenging.
Faded or Yellowed Colours: As cataracts progress, they can cause colours to appear dull, faded, or yellowed. This can affect the perception of colours in the environment and may be particularly noticeable when looking at vibrant or contrasting hues.
Double Vision: Cataracts can sometimes cause double vision or diplopia, where objects appear to have a ghost-like image. This occurs when light entering the eye is scattered or distorted by the cloudy lens, resulting in overlapping images.
Frequent Changes in Eyeglass Prescription: Individuals with cataracts may experience frequent changes in their eyeglass prescription as the cloudiness in the lens alters their refractive error. Despite updating their prescription, they may still struggle with vision clarity. This is a good sign that prescription glasses are not the solution in this case.
Difficulty with Night Vision: Cataracts can impact night vision, making it difficult to see clearly in low-light conditions. This can affect activities such as driving, particularly when encountering oncoming headlights or streetlights.
Progressive Vision Loss: As cataracts advance, vision loss becomes more pronounced and can significantly impact daily activities such as reading, watching television, or recognizing faces. Vision loss and vision problems have repeatedly shown to be a prioritized concern on many people’s minds when all 5 senses are considered.
Any of the above symptoms is a good reason to do a quick search for the best Calgary Optometrist and get an eye exam near you at their eye clinic in Calgary.
Types of Cataracts Causing Blurry Vision
Understanding the different types of cataracts can help individuals recognize symptoms early, seek appropriate treatment, and maintain good eye health. The good news is that an experienced Eye Doctor can help identify which type of cataract you have. Because this is basic training for Eye Doctors, fortunately, you don’t need to see the top Calgary Optometrist for an accurate diagnosis. Here, we explore the various types of cataracts and their distinguishing features:
Age Related Cataracts
Nuclear Cataracts: These cataracts affect the central (nuclear) region of the lens and are often associated with aging. They typically develop gradually, starting with changes in the lens proteins that cause it to become yellow or brown in colour. Nuclear cataracts can lead to nearsightedness and difficulty seeing objects clearly, especially at close range. As they progress, they may cause a significant decline in visual acuity and require surgical removal.
Cortical cataracts: These are a specific type of cataract characterized by the presence of opacities or cloudiness that develop in the outer layer of the eye's lens, known as the cortex. These opacities typically form in a wedge or spoke-like pattern and extend inward from the outer edge of the lens toward the center. As cortical cataracts progress, they can interfere with the passage of light through the lens, leading to blurred or distorted vision.
Posterior Subcapsular Cataracts: Subcapsular cataracts form on the back surface of the lens capsule, which is the thin, elastic membrane that surrounds the lens. These cataracts can develop with age, however these cataracts tend to develop more rapidly than other types and can significantly impair vision, especially in individuals with diabetes or those who take high doses of corticosteroid medications. Subcapsular cataracts may cause symptoms such as glare sensitivity, halos around lights, and difficulty reading or seeing in bright light.
Congenital Cataracts
Congenital cataracts occur in newborns or infants and may be present at birth or develop shortly afterward. They can be caused by genetic factors, maternal infections during pregnancy, or other developmental abnormalities. Congenital cataracts can vary in severity, from small areas of cloudiness to large opacities that obstruct vision. Early detection and intervention are crucial to prevent long-term vision problems in affected infants.
Traumatic Cataracts
Traumatic cataracts result from eye injuries, such as blunt trauma or penetrating wounds. The trauma disrupts the normal structure of the lens, leading to clouding and vision loss. Symptoms may develop immediately following the injury or gradually over time. Depending on the severity of the trauma, traumatic cataracts may require prompt surgical treatment to restore vision and prevent further complications. This is considered an eye emergency and needs to be seen as a walk-in eye exam emergency. The eye exam cost in Calgary and eye exam cost in Alberta for this type of visit is covered under Alberta Health Care, thus making it a free eye exam. So please don’t hesitate to reach out to a Calgary Eye Clinic near you and book a walk in eye exam.
Secondary Cataracts
Secondary cataracts can develop as a complication of other eye conditions or medical treatments. For example, they may occur from prolonged use of corticosteroid medications, radiation therapy for cancer treatment, or as a complication of other eye surgeries, such as vitrectomy. Secondary cataracts may develop months or even years after the initial treatment or procedure and can cause vision problems like age-related cataracts.Understanding the different types of cataracts is essential for early detection, timely intervention, and appropriate management. Regular eye exams, especially for individuals at higher risk, such as older adults or those with underlying medical conditions, can help identify cataracts in their early stages when treatment options may be more effective. If you experience any changes in your vision or notice symptoms suggestive of cataracts, consult an eye care professional for a comprehensive evaluation and personalized treatment recommendations.
Detecting Cataracts
Cataracts often develop gradually and may not cause noticeable symptoms in the early stages. Routine eye exams enable Optometrists to detect cataracts at their earliest onset, facilitating prompt intervention and management. In addition to detecting cataracts, routine eye exams play a crucial role in preserving overall eye health and detecting other ocular conditions such as glaucoma, diabetic retinopathy, and age-related macular degeneration. These eye exams provide valuable insights into the health of the eye's internal structures, facilitating early intervention and preventing vision loss. If your Optometrist near you suspects that you have cataracts, they will perform a dilated eye exam.
A dilated eye exam involves the administration of special eye drops to widen the pupil, allowing for a comprehensive examination of the eye's internal structures. Dilated eye exams provide a thorough assessment of the lens, allowing Optometrists to identify characteristic signs of cataracts such as cloudiness, opacity, or changes in lens coloration. This comprehensive evaluation aids in accurately diagnosing cataracts and determining their severity.
For individuals with known risk factors for cataracts or those who have previously been diagnosed with cataracts, regular dilated eye exams are essential for monitoring the progression of cataracts over time. By tracking changes in the lens and assessing visual function, Optometrists can tailor treatment plans and interventions accordingly. Timely detection of cataracts through dilated eye exams enables Optometrists to initiate appropriate interventions to manage the condition effectively. Call our Southcentre Mall Calgary Eye Clinic if you are looking to get a dilated eye exam with a qualified Calgary Optometrist. We have walk-in eye exams for dilations available every day.
Treatment and Management
Lifestyle Modifications:
Quit Smoking: Smoking is a significant risk factor for cataract development and progression. Quitting smoking can help reduce the risk and slow the progression of cataracts. Smoking cessation programs and support groups are available to assist individuals in quitting tobacco use.
Protect Against UV Radiation: Ultraviolet (UV) radiation from sunlight can accelerate cataract formation. Wearing sunglasses with UV protection and wide-brimmed hats when outdoors can help shield the eyes from harmful UV rays. Prescription glasses with transitions or prescription sunglasses are a great way to keep your eyes protected. Our Eye Clinic in Southcentre Mall Calgary has a selection with options for everyone. The cost of glasses is very affordable to make sure you don’t break the bank just to take care of your eyes.
Maintain a Healthy Diet: A diet rich in antioxidants, vitamins, and nutrients may support overall eye health and reduce the risk of cataracts. Incorporating fruits, vegetables, whole grains, and lean proteins into the diet can provide essential nutrients for maintaining optimal eye function. There are eye supplements and eye vitamins that can help your eyes too. It’s best to ask your Calgary Optometrist at your next eye exam about these.
Prescription Eyewear:
As cataracts progress, prescription eyeglasses may need to be adjusted to accommodate changes in visual acuity. Regular appointments with your Calgary Optometrist will ensure that prescription lenses remain accurate and effective. It's important to note that while glasses can improve vision, they cannot fully correct visual acuity when cataracts are limiting clarity. As cataracts progress, vision may continue to deteriorate despite wearing glasses, emphasizing the need for timely intervention. Our Southcentre Mall Calgary Eye Clinic doesn’t charge for glasses repairs and for glasses adjustments.
Cataract Surgery:
During cataract surgery, the cloudy lens is removed and replaced with an artificial intraocular lens (IOL) to restore clear vision. Advanced surgical techniques, such as phacoemulsification, minimize incision size and promote faster recovery times. Cataract surgery is recommended when cataracts significantly impair vision and interfere with daily activities. Top Optometrists assess factors such as visual acuity, cataract severity, and the patient's overall health to determine the appropriate timing for a referral for surgery.
Cataract lens upgrades, also known as premium intraocular lenses (IOLs), offer individuals undergoing cataract surgery additional benefits beyond simply restoring clear vision. These advanced lenses provide opportunities for improved visual outcomes and reduced dependence on glasses or contact lenses
Your Calgary Optometrist can play a crucial role in guiding you through the process of cataract surgery, including exploring premium lens options. They can assess your eye health, discuss your visual goals and preferences, and provide recommendations based on their expertise and knowledge of your individual needs. Additionally, your optometrist can help coordinate referrals to reputable cataract surgeons who specialize in the specific type of lens upgrade you're considering. By working closely with your Optometrist near you, you can receive personalized guidance and support throughout your cataract surgery journey, ensuring that you make informed decisions and achieve the best possible visual outcomes.
