Scleral contact lenses are a type of specialty contact lens that can provide improved vision and comfort for individuals with certain eye conditions. In this section, we will explore what Scleral Lens Insertions are, who can benefit from them, and how they work.
What are Scleral Contact Lenses?
Scleral contact lenses are larger in diameter compared to traditional contact lenses. They are designed to vault over the entire cornea and rest on the white part of the eye, known as the sclera. This unique design allows scleral lenses to create a tear-filled reservoir between the lens and the cornea, providing a smooth and comfortable fit.
The main purpose of scleral lenses is to correct vision and provide a protective barrier for the cornea. They can be used to address various eye conditions such as keratoconus, extreme dry eyes, and post-refractive surgery complications. Scleral lenses are also beneficial for individuals with irregular corneas or those who have had corneal transplants.
Who Can Benefit from Scleral Lenses?
Scleral lenses are particularly beneficial for individuals who have been unsuccessful with traditional contact lenses or are unable to undergo laser eye surgery. They can provide visual improvement and comfort for patients with conditions such as keratoconus, where the cornea becomes thin and cone-shaped, resulting in distorted vision.
Additionally, individuals with extreme dry eyes, often associated with conditions like Sjögren’s syndrome or graft-versus-host disease, can benefit from scleral lenses. The tear reservoir created by the lenses helps to keep the cornea hydrated and protected from the drying effects of the environment.
Post-refractive surgery patients, such as those who have undergone radial keratotomy (RK), may also find relief with scleral lenses. These lenses can help to correct any remaining refractive errors and provide improved vision.
How Scleral Lenses Work
Scleral lenses work by creating a liquid-filled space between the cornea and the lens itself. This space, often referred to as the “tear reservoir,” acts as a cushion, protecting the cornea and providing a smooth optical surface for light to pass through. The fluid-filled reservoir also helps to improve comfort by providing constant lubrication for the eye.
To ensure a proper fit, scleral lenses are custom-made for each individual. This involves a detailed fitting process conducted by a qualified eye care professional. The fitting process includes measurements of the cornea and sclera to determine the appropriate lens size and shape.
Once the lens is fitted, it can be inserted into the eye using a specialized scleral lens plunger. This tool helps to hold and guide the lens onto the eye without touching the lens surface, reducing the risk of damage.

Benefits of Scleral Contact Lenses
Scleral contact lenses offer numerous benefits for individuals with specific eye conditions. These lenses provide a comfortable and effective solution for addressing visual impairments and eye sensitivities. Let’s explore some of the key benefits of scleral contact lenses:
Improved Visual Clarity
One of the primary advantages of scleral contact lenses is their ability to provide improved visual clarity. These lenses are designed to vault over the cornea, creating a smooth and even surface for light to pass through. This helps to correct refractive errors, such as astigmatism, and provide sharper and more accurate vision. Scleral lenses can be particularly beneficial for patients with conditions like keratoconus, where the cornea becomes irregularly shaped. The lenses help to neutralize this irregularity and enhance visual acuity.
Enhanced Comfort for Sensitive Eyes
Individuals with sensitive or delicate eyes often struggle to find comfortable contact lens options. Scleral lenses offer a solution by providing a protective cushion of tears between the lens and the cornea. This cushion helps to reduce friction and irritation, offering a more comfortable wearing experience. The lenses also minimize the risk of debris or irritants coming into contact with the cornea, making them suitable for patients with conditions such as extreme dry eyes or post RK surgery.
Protection and Moisturization for Dry Eyes
Dry eyes can cause significant discomfort and affect visual acuity. Scleral lenses can help alleviate these symptoms by acting as a reservoir for artificial tears. The space between the lens and the cornea acts as a barrier, preventing tears from evaporating too quickly and maintaining a constant moisture level on the surface of the eye. This can provide relief for individuals with chronic dry eye conditions or those who experience excessive tear evaporation.
Scleral contact lenses are a valuable tool for individuals seeking improved vision and comfort. Whether you require better visual clarity, relief for sensitive eyes, or protection for dry eyes, these lenses can make a significant difference.
