What Is Keratoconus?
Keratoconus is an eye disorder that causes thinning or weakening of the cornea which in turn causes the cornea to bulge out in a cone shape.
What Causes Keratoconus?
- In around 7% of cases it is attributed to genetics, which is why an eye doctor will often see more than one patient with keratoconus from the same family.
- Reduced activity of enzymes which cause a build up of free radicals that weaken the cornea through oxidation.
- Increased activity of the protease enzymes which break down the collagen.
- Studies have linked it to; frequent eye rubbing, exposure to UV rays, atopic diseases such as asthma or allergies, people with Down Syndrome, and improper contact lens fitting.
What Are the Symptoms Of Keratoconus?
Keratoconic patients may experience some of the following symptoms, symptoms usually start in the late teens.
- Ghosting of light, experiencing trails of light or streaking/flaring of light especially when seen at night
- Blurred vision
- Increased light sensitivity and issues with night time driving
- Irritated eyes that causes the need to rub
- Eye strain or eye pain
- Frequent changes of prescriptions or vision that cannot be corrected with glasses
What Are the Treatment Options For Keratoconus?
There are a variety of different contact lens designs that are effective for patients with Keratoconus. Your eye doctor will evaluate your eyes using a specialized OCT machine which produces a 3d map of your cornea. When evaluating a keratoconic patient, the OCT allows for earlier detection and a more accurate evaluation. In addition the detailed topography of the cornea allows your optometrist to assess what contacts will provide the best solution for your eye by virtually overlaying the contact on the 3d map of your cornea.
- Rigid Gas Permeable Contact Lenses: Considered the ideal solution for patients with Keratoconus, because of its rigidity it provides a new smooth surface for optimal refraction.
- Customized Soft Toric Contacts: Many of the large contact lens companies have been developing new and innovative soft contacts that are customized to your eye. The benefit of a soft contact is the improvement in comfort when compared to RGP contacts. The main drawback is that they are less effective in low contrast situations then RGP contacts.
- Hybrid/Piggyback Contacts: Hybrid is a cross between RGP and Soft contacts where the inner part of the contact is RGP and the outer is soft. Designed to increase comfort while not forfeiting visual acuity. Piggyback is the process of fitting a RGP contact over a soft contact to increase comfort.
- Scleral Lenses: Scleral lenses are widely becoming a popular solution for keratoconus due to their comfort and effectiveness. They are much larger than traditional RGP contacts which has three main benefits: they apply less pressure on the cornea, they are less likely to move due to blinking, and they don’t let dust to get underneath them.
What Is Irregular Astigmatism?
Irregular Astigmatism is a condition whereby the cornea has irregular shapes such as ridges, peaks and valleys which cause the light coming into the eye to not be focused correctly.
What Causes Irregular Astigmatism?
- Naturally occurring corneal degeneration’s such as Keratoconus, Pellucid Marginal Degeneration, and Keratoglobus.
- Genetic inheritance
- As a result of eye surgery such as Lasik, PRK, and RK.
- Due to an eye injury such as a cut to your cornea or due to an infection such that causes scarring.
What Are The Symptoms of Irregular Astigmatism?
- Trouble focusing on close and far images
- Blurred or distorted vision
- Seeing multiple images
- Often closing one eye will enable the patient to see clearer
What Is The Best Treatment Option For Irregular Astigmatism?
Our eye doctor will preform a thorough evaluation including a highly specialized screening using our Optical Coherence Tomogrophy (OCT) with a special Anterior Camera. In most cases a custom made rigid gas permeable contact will be prescribed. This contact will cover the cornea and due to its uniform curvature will correct the ridges and bumps in your cornea.
