Describing Keratoconus
Keratoconus is a non-inflammatory degenerative eye disease. Keratoconus causes damage to the collagen fibers in the cornea causing them to grow weaker. When it reaches a weak enough point in the fiber it bulges up like that of a hernia. This disorder causes irregular astigmatism, steeping of the cornea, and vision loss in the cornea. This dramatically affects the sufferer’s daily life by making everyday activities like driving, reading and often just completing normal daily activities most take for granted.
The Vision loss caused by Keratoconus can be mild to severe in one or even both eyes. Keratoconus is diagnosed in 54.5 people out of every 100,000 in the general population.
With the above said, a percentage of diagnosed patients with keratoconus often seek Lasik out to correct their poor vision. Lasik surgery IS NOT an efficient treatment for those with Keratoconus because of its underlying risks for complications and high incidences of causing a rapid progression of the condition, which requires even more surgery, possibly leading to the need for a cornea transplant.
Diagnosing Keratoconus
Most vision correction surgeons use corneal topography to map out the eyes before treatment. This provided them with a better view of the corneas of each patient case. They use this mapping of both eyes to compare the changes and their differences. Patients must be mapped in both eyes since it is quite useful to detect and evaluate which stage of keratoconus a patient has. Over 90% of patients with keratoconus have it in both eyes and just over 6% are affected in one eye only. Keratoconus often begins in one eye first and then spreads to the other. However, in many cases, by the time the patient is often diagnosed with Keratoconus have been affected in both eyes.
If patients are not diagnosed properly before Lasik they can develop Lasik-induced Keratoconus or Keratoectasia. There are many symptoms of Keratoconus and proper regular exams of both eyes is best for catching Keratoconus or other vision problems early. Here is a list of Keratoconus symptoms:
Glare and/or light sensitivity
Frequent Prescription Changes
Progressive Nearsightedness
Irregular Astigmatism
High Amounts Of Astigmatism
Always check with your eye doctor if you feel you have more serious case. In addition, finding someone who is familiar with early signs of Keratoconus is also a wise move since some doctors might not be familiar with the condition off hand. Taking care of your eyes and vision is always a smart decision. Always consult with your eye doctor if there are changes in your eyesight.
