Scleral Contact Lenses: Transforming Eye Care for Complex Vision Needs
Scleral contact lenses are a specialized contact lens that rests on the sclera, or the white part of the eye, rather than directly on the cornea. The lenses are designed to vault over the cornea and create a tear-filled reservoir between the back of the lens and the eye’s surface. This unique structure has made scleral contact lenses perfect for people with many forms of eye conditions and challenges in vision, particularly for those who have challenges fitting traditional contact lenses. Its design, comfort, and effectiveness have made them the most popular for complicated needs in eye health in many patients.
One of the primary benefits of scleral contact lenses is their capacity to offer comfort and corrective vision for people with irregular corneas. These include keratoconus, a condition in which the cornea thins and bulges into a cone shape, leading to distorted vision. In such cases, conventional contact lenses cannot be used because of the irregular shape of the cornea. Scleral lenses provide a stable, uniform surface that enhances vision by neutralizing the irregularities of the cornea. This makes scleral contact lenses a precious option for patients whose vision cannot be fully corrected with glasses or standard soft contact lenses.
Benefit of Scleral Contact Lenses
Besides their benefits to patients with keratoconus, these lenses are often prescribed to patients with dry eye syndrome. Dry eyes make conventional contact lenses painful to wear because they need a good tear film in order to stay moist and comfortable. The reservoir of fluid trapped against the eye by scleral lenses serves to alleviate dryness, thus providing continuous hydration for all hours of the day. It is particularly beneficial to people with conditions like Sjogren’s syndrome, ocular surface disease, or post-LASIK dryness who often find standard contact lenses to be intolerable to wear.
Another category of patients is those who have had a corneal transplant or other types of corneal surgery. After this surgery, the cornea may be left in a way that makes it unsuitable for standard glasses or contacts. Scleral contact lenses are a very non-invasive way of correcting post-surgical irregularities and often deliver better vision and comfort than conventional alternatives.
The fitting of scleral contact lenses is a procedure requiring specific expertise by an eye care professional. Since the eyes of each patient vary, the need for scleral lenses varies with every one of them, hence the lenses are usually ordered in a customized manner in order to achieve the best fit and correction of vision. A lot of procedures are followed while fitting the lenses, including detailed measurements and mapping of the cornea, which would help in designing a comfortable yet effective lens for every individual. The main drawback to this process is that it can be both time and cost-consuming as compared to the conventional fit lenses. For most patients with complicated visual comfort, advantages normally outweigh these drawbacks.
Scleral Contact Lenses
Mini- scleral contact lenses come in different diameters ranging from a diameter for full-sized scleral lenses. The extent the lens will spread out over the eye also determines the degree at which the sclera will be covered. Mini-scleral lenses are smaller, covering only a small portion of the sclera, whereas full-sized scleral lenses stretch out to cover more parts of the sclera. The size of the lens would depend on several criteria such as the severity of the patient’s eye condition, lifestyle needs, and the eye care provider’s recommendation.
Although scleral contact lenses have many advantages, it may be a bit of hassle in the care factor. They require to be very deep cleaned and well-handled so as to prevent irritation and infection of the eyes. A checkup with the eye care professional is very important since these lenses are not left causing discomfort to the wearer or causing harm to one’s eyes. In case a person takes good care, then scleral lenses remain long-lasting than soft contact lenses. This makes them relatively more durable and cost-efficient for the patient.
Conclusion
Scleral contact lenses are thus provided as a versatile option in the management of patients presenting with challenging eye conditions including keratoconus, dry eye syndrome, post-surgical corneal irregularities, among many others. They allow one to rest on the sclera and create a chamber filled with tears for enhanced comfort, hydration, and vision for patients who, otherwise, cannot be controlled with conventional contact lenses. As eye care professionals become increasingly skilled at fitting these lenses, scleral contact lenses are becoming fast favorites among the more contemporary alternatives to contact lenses in those requiring high degrees of vision correction and comfort.
