Keratoconus is a condition where the cornea progressively changes shape. The cornea, the transparent film covering the pupil and iris, loses its structural form and bulges. Scleral contact lenses Chicago can address problems like blurred vision and sensitivity to light. Find out why these lenses are the best for managing symptoms of keratoconus.
Scleral lenses for keratoconus and astigmatism
Conventional contact lenses and regular glasses can improve vision for people with keratoconus. But as the disease progresses, the cornea bulges and distorts light further. At the advanced phases of keratoconus, the cornea may transform into a cone shape.
Scleral lenses are custom-made with a design that fits the sclera, the white portion of the eye. They are wide and hard lenses that maintain cornea shape, reducing irregularities. For cases of corneal distortion, they offer superior vision and light perception.
The larger diameter ensures the lenses alight to the eye’s center. They are, therefore, more stable than conventional options. You can wear the lenses when performing routine chores or sporting activities.
Benefits of scleral lenses
They relieve eye dryness
A dry eye is a condition where the eye fails to produce sufficient tears or loses it rapidly through evaporation. Statistics show half of the people using conventional soft lenses have dry eyes. Soft lenses absorb moisture on the tear film, leaving the eye dehydrated.
Keratoconus may worsen the inflammatory process causing dry eye. The absence of moisture can increase scleral instability. You may experience frequent incidences of eye irritation.
Scleral lenses are the best option since they fit around the white part without touching the cornea. Regular contact lenses can interfere with nerve sensitivity around the tear film. That limits the production of tears, which protects the eye.
Additionally, scleral lenses leave an opening around the cornea, allowing tears to accumulate on the eye’s surface. The moist environment prevents irritation. Unlike conventional lenses, it arrests the progression of keratoconus.
Address a wide range of vision problems
The scleral lens covers a larger area and offers a broader peripheral vision. That makes it suitable for outdoor activities and sports. They can cancel out the glare and intense light that can affect your vision and the health of your eyes.
Corneal mapping shows scleral lenses can address a range of refraction issues. It can enhance overall perception for keratoconus patients of all ages with corneal irregularities.
A design that ensures optimum comfort
The larger diameter allows the lens to remain in the same position with minimal movement. The structure includes a saline solution that creates a healing environment for the eye.
The wider area prevents the eyelid from rubbing against the lens. Conventional lenses tend to irritate the eyelid and cause discomfort.
The lens is made from durable materials that protect the eyes from impurities. It can minimize discomfort for people susceptible to allergies.
Despite its durable and study design, scleral lenses are porous, ensuring a steady oxygen supply. The lenses are custom-made to match the eye’s contours. They offer exceptional comfort for keratoconus patients.
