Keratoconus is a non-inflammatory disorder that affects the anatomy and physiology of the cornea and is diagnosed by an eye doctor. The cornea becomes thinned and steepened, resulting in distorted vision, sensitivity to light, and decreased vision. Symptoms typically manifest in a person’s younger years, usually the late teens or 20’s and can begin to rapidly worsen, causing vision to become very blurry and distorted. If you have been diagnosed with or think you might have keratoconus, call our Lake Worth eye doctors and optometrists who specializes in keratoconus.
Custom individual keratoconus treatment plans may depend on a number of factors, including:
Severity of your keratoconus
Whether your keratoconus is stable or progressives
Thickness of your cornea and other corneal biometrics
You may have already been told by your eye doctor that hard contact lenses, such as scleral lenses, surgery or procedures, such as corneal cross-linking (CXL) or corneal implants, is necessary. However, many keratoconus patients need a combination of treatments to experience the ultimate goal of fully restored vision.
Intacs (Corneal Implants)
Custom Soft Contact Lenses
This procedure (sometimes referred to as corneal collagen cross-linking or CXL) performed by an eye doctor uses riboflavin drops combined with UVA light to strengthen the cornea. The procedure is designed to stop further progression of corneal ectasia (or thinning), which is typically seen in patients with keratoconus, pellucid marginal degeneration (PMD) and in patients who have had LASIK or RK eye surgery.
There are two forms of CXL that an eye doctor may choose from: epithelium-off (epi-off) and epithelium-on (epi-on). Epi-off CXL involves removing the corneal epithelium and dropping a formula of riboflavin solution on the cornea for a period of time followed by controlled UVA light exposure. The epi-on procedure uses a different concentration of riboflavin solutions and different exposure time with UVA, and does not involve the removal of the corneal epithelium.
Scleral lenses are large sized hard lenses that rest on the white part of the eye called the sclera and completely vault over the cornea, where the distortions of keratoconus originate from. Scleral lenses are fit by expert eye doctors who are specially trained optometrists, highly skilled at creating a perfect fitting lens to correct vision in a comfortable way. Scleral lenses are typically made out of gas permeable materials so that enough oxygen gets to the cornea creating a healthy wearing environment. Scleral lenses are filled with a liquid called saline, preservative free is recommended. Our Lake Worth eye doctors have the latest technology to fit scleral lenses -this means that you can enjoy very crisp vision with an exceptionally comfortable experience with scleral lenses, which are typically the healthiest corrective options for patients suffering from keratoconus.
Intacs are prescription corneal implants that were previously used as a form of refractive surgery for treating low-level myopia and nearsightedness. Recently, this surgical option has been approved for use in treating keratoconus.
These surgically applied plastic implants are inserted just under the eye’s surface in the periphery of the cornea and help re-shape and reinforce the cornea, thereby eliminating some of the irregularities caused by keratoconus in order to provide improved vision. The procedure takes approximately 10 minutes to complete.
