What are Scleral Lenses?
Generally, they are a specialized type of contact lens that hold artificial tears. Scleral lenses also have a small clear, but they have no plastic rim or band as other types of lenses do. In fact, the entire lens is made from the same material as a traditional contact lens – silicone hydrogel.
Who is Best Suited to Wear Scleral Lenses? They are usually used for people with very nearsightedness, farsightedness, and astigmatism – all of which happen to be very delicate eye conditions that can be greatly helped by an improvement in the patient’s vision. There are different sizes available for these smaller, lighter contact lenses that will be able to be worn comfortably. Scleral lenses usually come in either a soft, firm or a silicone hydrogel type, so it depends on the eye condition as to which one is best suited. These special lenses are not recommended for children or women who are pregnant.
eye disorders in which scleral lenses may be prescribed include cataracts and dry eyes
The most common eye disorders in which scleral lenses may be prescribed include cataracts and dry eyes, both of which require a larger replacement than would be used for astigmatism. Cataract surgery is performed under anesthesia, and it is often accompanied by a significant amount of pain for the patient. Dry eyes is a condition where the eye does not receive sufficient lubrication, and as a result the eye becomes drier and more easily irritated.
How are Scleral Lenses Provided for Comfort and Eye Health? Typically, these special eye wear provide a higher level of comfort than traditional corneal lenses because the materials are soft, so they do not irritate the eye. Additionally, the materials do not absorb much of the moisture that is in the eye, so there is little need for lubrication or moisture retinoids. Scleral surface and gas permeable lenses allow for a greater degree of hydration in the eye than traditional corneal lenses do, so there is less dry eye syndrome associated with wearing these types of lenses.
Are There Different Types of Scleral Lenses?
Yes, there are two main categories of this special type of lenses: the rigid lenses, and the soft clear lenses. Both of these provide excellent vision correction, but rigid lenses are typically used for individuals needing very firm vision, while the soft sclera lenses can be used by people who prefer softer vision correction. The size and shape of the toric lens will also determine which type of schema is best for the patient. Toric lenses have smaller particles than the schema used in soft lenses, thus making the visual correction that occurs from using these larger particles more apparent.
Can Scleral Lenses Prevent Or Reduces Myopia, Hyperopia or Astigmatism? Overall, scleral lenses have shown to provide a better vision correction than standard contact lenses do, and have fewer risks of dry eyes or irritation associated with them. However, there are certain circumstances where scleral lenses may pose a danger to you or your eye. If you have an eye condition that requires special surface treatment, such as cataracts or macular degeneration, you should contact your eye doctor before wearing sclera. If you have an eye disorder or other chronic conditions that affect the eye, you should consult with your eye care professional before using sclera to correct any vision issues you have.
