Corneal Collagen Cross Linking In Oakville, Ontario
Collagen Cross Linking In Oakville, Ontario
There’s a new treatment in town, and it could very well help with your Keratoconus symptoms. But first, let’s talk about what Keratoconus is and how it can affect your daily activities.
What Is Keratoconus?
Keratoconus (keh-rah-toe-cone-us) is an eye disorder in which the round dome-shaped cornea progressively thins causing a cone-like bulge to develop. This cone-shaped cornea causes light to be refracted incorrectly, resulting in blurred vision, rendering everyday activities, such as reading and driving, a struggle.
Keratoconus Treatment Methods in Oakville
Keratoconus can be treated in a number of ways
Collagen Isn’t Only For Lip Enhancement
Most people know about collagen's use in cosmetic surgery, such as making the lips appear fuller. What many don’t know is that it’s a protein developed inside the human body and can be found in the skin, muscles, and various ligaments.
The cornea of the eye also contains collagen. It is made up of tiny collagen fibers that lie in an intertwined fashion, ensuring that the cornea remains clear. As mentioned above, Collagen Cross-Linking can be used to treat Keratoconus to improve vision. The procedure is called ‘cross linking’ due to the placement of bonds in between the collagen fibers. These bonds provide support to stabilize the cornea.
How Does Collagen Cross-Linking Help My Keratoconus?
Collagen Cross-Linking, or CXL, is considered an ideal treatment for Keratoconus because the procedure flattens and strengthens the cornea, helping to reverse its misshapen form back to its correct one. Once the cornea returns to its original dome-like shape, light can once again hit the pupil correctly, providing improved vision.
CXL is most effective in patients who have been recently diagnosed with Keratoconus; the more the condition advances, the more difficult it is to manage. While CLX does not reverse the corneal shape completely, it can slow down the Keratoconus progression. In most cases, the patient will still need some type of vision correction assistance, such as eyeglasses or contact lenses.
The Collagen Cross-Linking Procedure
When a patient is determined to be a good candidate for Collagen Cross-Linking, an ophthalmologist will perform the minimally invasive procedure, which typically lasts between 30-60 minutes. The CXL procedure is done in office, so there is no need for a hospital visit.
There are actually two types of CXL procedures. One is called Epithelium-off, and the other is called Epithelium-on. The difference between them has to do with the epithelium, also called “epi”, which is a tissue located on the outside layer of the cornea.
Discuss with Dr. Fallon Patel, Dr. Angela Fu, Dr. Shobitha Ratnakumar, Dr. Sandy Zhu and Siva Sivalingam to determine which version of the CXL treatment is right for your condition. Each one has its benefits and risks in terms of procedure and recovery time.
What Are The Advantages Of Scleral Lenses? It’s All In The Shape!
Although radiation caused by UV light can be harmful to one’s health, the amount of UV applied during the CXL procedure does not reach dangerous levels. According to The National Center for Biotechnology Information, a wavelength of 360–370 nm with an accumulated irradiance of 5.4 J/cm2 ensures that the exposure of all structures is below harmful levels.
Additionally, the riboflavin eye drops that the patient receives prior to the UV light application serves as a solid wall of protection against any potential radiation effects.
In April 2016, after conducting rigorous testing and reviewing case studies, the FDA approved the CXL procedure as an effective treatment for slowing down the progression of Keratoconus.
Just as with any medical procedure, there are some things you should know beforehand and some preparation you will need to do. On the day of the procedure, avoid wearing any eye makeup, creams, lotions, perfume, or cologne. The ophthalmologist will perform CXL on one eye at a time. It will affect your vision in the first few hours, so make sure someone can drive you home after the procedure.
Recovery time can be different for each patient, and depends on the type of CXL chosen. For the Epi-off procedure, there may be some pain felt over a few days’ time. As the epi heals, the pain will lessen and eventually fade completely. It may take up to a week and a half to resume normal activities. If the Epi-on version was done, then recovery time tends to be quicker and virtually painless.
Most eye doctors recommend not wearing contact lenses in the first few days following Collagen Cross-Linking. Others suggest waiting several weeks, but this is contingent upon the type of CXL performed on the patient.
Collagen Cross Linking Side Effects
Every type of medicine or medical procedure carries the risk of potential side effects. Pregnancy, breastfeeding, over the counter drugs, other medical conditions, and even a patient’s personal lifestyle can conflict with CXL. Because The Scleral Lens and Keratoconus Center at Dr. Fallon Patel and Associates believes that an informed patient is a smart patient, we encourage you to become aware of the possible side effects of Collagen Cross-Linking. These can include:
If you think you may be experiencing any of these side effects, talk to your eye doctor right away.
Remember, Keratoconus is a condition that requires ongoing treatment by a qualified eye doctor. Even after Collagen Cross-Linking has been performed, it’s important that you or a loved one who suffers from this disease find an eye doctor with you are comfortable with and trust to monitor the condition for the long-term.
