Scleral contacts are large-diameter, gas-permeable contact lenses specifically designed to extend across the whole surface of the cornea. They are mainly resting against the white part of the eye (the sclera). Scleral contacts can transform a non-uniform cornea into a smooth, ocular surface, the visual problems caused by keratoconus and other forms of corneal ectasia. Scleral lenses have an extra-wide diameter and are spread out fully across the corneal surface. It makes them comfortable and practical for individuals with irregular corneas. In addition, scleral lenses are designed without much or any movement of the lenses.
More complicated conditions include advanced keratoconus, pathologically dry eyes, or severe eye surface diseases. It may require larger tear pools and is typically fitted with larger scleral lenses. They can retain fluids or bridge more considerable changes in the cornea’s curvature. After an examination with contacts, your healthcare provider may recommend a scleral lens if they find you have severe dry eye syndrome. Following lasing, Lasik, higher-order aberrations, complications following corneal transplantation. Complications following corneal transplantation and pellucid degeneration. Keratoconus, ocular anomalies, or other corneal abnormalities. Suppose you suffer from dry eyes and you also need vision correction. In that case, scleral lenses are an additional benefit, as your other contact lens options might be limited due to compromised ocular surface conditions.
Fortunately, the sclera contacts design of lenses can overcome challenges associated with other types of contact lenses. These lenses are particularly effective at addressing vision correction. A liquid layer helps smooth imperfections caused by dry eyes, providing a more refractive surface. The Space Between Your Cornea And The Back Surface Of Your Scleral Lens. The back cover of your scleral lens acts like a fluid reservoir, providing comfort to those who suffer from dry eyes and would not otherwise tolerate contact lenses; between the back surface of a scleral lens and your eyes, your tears and moisturizing gels.
The gap between your cornea and the scleral lens is filled with a new solution of salt water each time you put on your lenses, which in turn provides a continuous source of moisture and comfort to the eyes. The scleral lens extends directly above your cornea, providing a clear, regular new surface to refract the light. Contacts often worsen dry eyes, but scleral connections allow space for fluid between the lens and the cornea.
Scleral contacts are halloween contact lenses commonly used for those with cornea abnormalities or the front window of their eyes, like keratoconus. Suppose you have been told that you cannot wear contacts because of an irregular cornea. Another issue, you should get a second opinion and ask your eye doctor about scleral contact lenses. Scleral contact lenses can be safe and effective for many eye conditions and refractive errors if fitted and used correctly.
Scleral lenses are used to treat a wide range of coloured eye contacts -related complaints, including dry eyes and keratoconus. Complications after surgery and difficulties wearing conventional contacts for comfort reasons. Scleral lenses are helpful when patients cannot seem to find a contact lens. That works well or addresses their visual problems. However, first-time users of scleral lenses are often concerned the lenses will be uncomfortable, primarily due to their large size and stiffness. Depending on the difficulty of the issue and the tolerance the individual’s eyes have for the scleral lenses. Adjustments to the lens parameters may be necessary, requiring additional lenses to be made and changed.
Scleral can also be used for individuals with eyes that are too sensitive to use other small corneal types of lenses but require a more rigid lens to correct visual conditions like astigmatism. In addition to keratoconus, scleral contact lenses can be used in eyes that have undergone a corneal transplant.
Scleral contact lenses contain silicone, which is oxygen-permeable, so oxygen can flow through the lenses, providing greater comfort and better eye health. Scleral lenses are called scleral lenses because rather than covering just part of the cornea. Scleral contacts are designed to rise above the cornea and rest on the sclera, leaving space for fluid between the lens and cornea. The primary advantage of scleral lenses is that they can be designed to fit every degree of corneal steepness or irregularity.
