For many people, vision changes can be subtle and slow to develop. But for those affected by keratoconus, the onset and progression are often times more dramatic. This progressive eye disorder can transform the shape of the cornea and impact day-to-day life in ways that are both frustrating and unexpected. Understanding keratoconus, it’s causes, its symptoms, and the evolving landscape of treatments can make all the difference when it comes to preserving lifelong vision.
Keratoconus is a condition in which the normally round cornea thins and bulges outward into a cone-like shape. Because the cornea is responsible for focusing most of the light entering the eye, any change in its shape can cause distorted or blurry vision. This can affect reading, driving, and even recognizing faces, and can sometimes come with increased light sensitivity or glare.
Although keratoconus often begins in adolescence or early adulthood, it can progress for several years before stabilizing. Both eyes are usually affected, though one eye may be more severely impacted than the other.
Researchers are still unraveling the exact causes of keratoconus. The evidence points to a combination of genetic, environmental, and possibly hormonal influences.
However, keratoconus can develop in people with no apparent cause. Early identification is crucial to prevent severe vision impairment.
Symptoms of keratoconus often appear gradually and can easily be confused with other vision problems at first. As the condition progresses, people may notice:
Today’s eye care professionals use advanced imaging techniques, such as corneal topography, to detect keratoconus in its earliest stages – sometimes before symptoms are even noticeable.
While there is no cure for keratoconus, advances in eye care have made the condition more manageable than ever before. Modern treatments can slow or stop its progression and improve vision in most cases. With early diagnosis and a personalized treatment plan, many people with keratoconus can maintain good vision throughout their lives.
Thanks to ongoing research and clinical innovation, individuals with keratoconus now have access to a wide range of treatment options. The best approach depends on the stage and severity of the disease.
In the earliest stages, glasses for keratoconus or soft contact lenses may correct vision by compensating for the changes in the cornea’s shape. As the condition advances, however, glasses may become less effective and specialty contact lenses are often required.
Rigid gas permeable (RGP) lenses, hybrid lenses, and scleral lenses are designed for irregular corneas. These lenses create a new, smooth surface over the eye, helping light focus more effectively and improving vision for those with moderate to advanced keratoconus.
Corneal cross-linking is a significant advancement in the treatment of keratoconus. This minimally invasive procedure involves applying riboflavin drops to the cornea and then exposing it to ultraviolet light. The corneal cross-linking procedure strengthens the corneal tissue by creating new collagen bonds, helping to stop the progression of the disease. For many patients, this outpatient procedure means they can avoid more invasive treatments later.
Corneal ring implants (ICRS) are small, curved inserts placed in the cornea to flatten its shape and reduce distortion. This minimally invasive procedure can improve vision and contact lens comfort in mild to moderate keratoconus. The implants are reversible and often delay the need for more invasive treatment.
For advanced keratoconus with severe thinning or scarring, corneal transplantation may be required. Full or partial transplants replace the damaged cornea with healthy donor tissue. Most patients regain functional vision, though recovery takes time and careful follow-up is essential.
RevitalVision is an innovative, clinically proven, non-invasive technology that uses computer-based visual training to enhance the way the brain processes information from the eyes. Rather than changing the cornea itself, RevitalVision strengthens neural visual processing. Recent studies have shown that RevitalVision can significantly improve visual acuity and contrast sensitivity in individuals with stable keratoconus who wish to enhance their vision beyond what is achievable with surgery, glasses, or contacts. The technology is FDA-cleared for use in individuals over nine years old and is CE-marked, with clinical evidence of effectiveness in a variety of eye diseases and vision conditions.
Many people with keratoconus can avoid surgery at an early stage of the disease through effective non-surgical options. These include:
Living with keratoconus means taking an active role in protecting your vision. These self-care strategies can make a real difference:
As technology and clinical research continue to evolve, the outlook for those living with keratoconus is more positive than ever before. Advanced treatments like RevitalVision offer new hope for patients diagnosed with this condition. Most people with keratoconus can now expect to live full, active lives with the right care, early intervention, and ongoing support from their eye care provider.
If you notice frequent changes in your glasses’ prescription, experience blurred or distorted vision, or struggle with light sensitivity, do not ignore these potential warning signs. Schedule an eye exam and discuss any concerns with your ophthalmologist or optometrist. Early action is the best way to protect your sight and stay ahead of keratoconus.
