Keratoconus - How We Provide The Best Fit and Save Time With Less Refits

Enhancing Vision and Comfort: The Role of Scleral Profiler and Anterior Segment OCT in Keratoconus Care in Atlanta


Keratoconus is a progressive eye disorder that affects the shape and structure of the cornea, the transparent front surface of the eye. This condition leads to visual distortions, blurriness, and even discomfort, significantly impacting a person's quality of life. Fortunately, advancements in technology have paved the way for more precise and personalized treatment options. In the realm of keratoconus management, the utilization of tools such as the Scleral Profiler and Anterior Segment OCT (Optical Coherence Tomography) has revolutionized the way optometrists and ophthalmologists approach patient care.


Understanding Keratoconus

Keratoconus is characterized by the thinning and bulging of the cornea into a cone-like shape, causing irregular astigmatism and visual impairment. The traditional approach to managing this condition involved the use of rigid gas permeable (RGP) contact lenses or, in severe cases, corneal transplantation. However, these methods didn't always provide the desired visual clarity and comfort for patients, especially in advanced stages of the disease.


The Role of Scleral Profiler

Scleral lenses have gained prominence as a viable solution for keratoconus patients due to their unique design and exceptional comfort. Unlike conventional lenses, scleral lenses vault over the cornea and rest on the white part of the eye, known as the sclera. This design offers several advantages:

  1. Stability: Scleral lenses provide stability and centration on the eye, reducing lens movement and improving visual acuity. This is particularly crucial for keratoconus patients whose irregular corneal shape can make lens fitting challenging.

  2. Comfort: Scleral lenses have a larger diameter compared to traditional contact lenses, allowing them to avoid direct contact with the cornea. This leads to enhanced comfort, as the lenses don't cause friction or irritation on the sensitive corneal surface.

  3. Protection: The gap between the cornea and the lens is filled with a tear layer, providing a protective cushion and maintaining a stable tear film. This is beneficial for patients with dry eye symptoms often associated with keratoconus.

The Advantages of Anterior Segment OCT

Anterior Segment OCT is a non-invasive imaging technology that provides high-resolution cross-sectional images of the anterior part of the eye, including the cornea. This tool offers valuable insights for precise diagnosis and personalized treatment plans:

  1. Corneal Mapping: Anterior Segment OCT produces detailed maps of the corneal surface, highlighting irregularities caused by keratoconus. This information guides the fitting process of scleral lenses, ensuring a tailored and comfortable fit.

  2. Customization: Each keratoconus case is unique, and a one-size-fits-all approach rarely yields optimal results. Anterior Segment OCT allows eye care professionals to customize lens designs based on individual corneal topography, maximizing visual acuity and patient satisfaction.

  3. Monitoring Progress: With regular OCT scans, practitioners can track the progression of the disease and make necessary adjustments to the lens fit or treatment plan. This proactive approach enhances long-term patient outcomes.

Conclusion

The advancements in technology have transformed the way keratoconus is managed. The Scleral Profiler and Anterior Segment OCT have enabled eye care professionals to create a personalized approach that caters to each patient's unique needs. This approach combines the comfort of stable scleral lenses with the precision of imaging tools, resulting in improved visual acuity and overall quality of life for patients with keratoconus. With the continuous improvement of technology, we can expect more effective solutions for managing this condition. At Atlanta Eye Associates, we strive to provide our patients with the best possible care by staying updated on the latest advancements in technology.
