Semi-Scleral Lenses

A Breakthrough for Irregular Corneas

Semi-scleral lenses offer a life-changing solution for individuals whose vision can no longer be clearly corrected with standard contact lenses or glasses. Larger than regular RGP lenses but smaller than full scleral lenses, they rest gently on the white part of your eye (the sclera) while vaulting over the cornea. This innovative design creates a smooth, tear-filled optical surface that enhances clarity, protects sensitive corneal tissue, and provides exceptional comfort throughout the day. 

Why Choose Semi-Scleral Lenses for Keratoconus?

  • Restores Clear Vision – Helps correct blurry or shadowy vision caused by keratoconus
  • Exceptional Comfort – The lens vaults over the cornea, reducing friction and irritation
  • Protects the Cornea – Acts as a protective barrier for fragile or thinning corneal tissue
  • Stable Fit – Offers better stability than soft or standard gas-permeable lenses
  • Improved Quality of Life – Enables patients to enjoy clearer vision for daily tasks, work, and lifestyle

How Do Semi-Scleral Lenses Work?

Semi-scleral lenses are uniquely designed to vault over the corneal surface without touching it, creating a tear-filled reservoir between the back surface of the lens and the irregular cornea. This fluid layer optically neutralizes corneal irregularities, providing a smooth refractive surface that restores clear and stable vision.

The lens rests gently on the sclera, which is the white and less sensitive part of the eye, ensuring comfort and minimizing mechanical stress on the cornea. This design not only enhances visual quality but also protects compromised or thinning corneal tissue, making semi-scleral lenses an ideal choice for conditions such as keratoconus, post-LASIK ectasia, or corneal scarring.

Who Are They For?

  • Individuals diagnosed with keratoconus
  • Patients with corneal ectasia, post-LASIK irregularities, or high astigmatism
  • Those who are intolerant to standard contact lenses
  • People who have not achieved satisfactory vision with glasses or soft lenses
  • Patients needing customized, long-wearing vision correction

Here’s What We’ll Check

Semi-Scleral Lens Fitting & Assessment involves a series of comprehensive eye tests to evaluate your vision, examine the health of your eyes, and determine the most suitable lenses for your lifestyle. These tests ensure a precise, comfortable fit and personalised care tailored to your individual visual needs.

Visual Acuity

Visual Acuity

Clinical measure of the eye's ability to resolve fine detail at a standardized distance. It quantifies the clarity or sharpness of central vision, which is essential for tasks such as reading, driving, and facial recognition.

Refraction

Refraction

This is a standard eye examination used to determine your refractive error and provide the correct prescription before issuing new glasses.

Dry Eye Assessment

Dry Eye Assessment

Diagnostic evaluation to determine the presence, type, and severity of Dry Eye Disease (DED). Dry eye occurs when the eyes do not produce enough tears or when the tear film is unstable, leading to discomfort, visual disturbances, and potential ocular surface damage.

Anterior Eye Assessment

Anterior Eye Assessment

Detailed examination of the front part of the eye, including the cornea, lens, and surrounding structures. Using advanced equipment, this assessment helps detect early signs of eye disease, monitor contact lens safety, and ensure your eyes remain healthy and comfortable.

Corneal Keratometry

Corneal Keratometry

Measurement of the anterior curvature of the cornea, particularly the central 3 mm zone, to determine the corneal refractive power and astigmatism.

Contact Lens Fitting

Contact Lens Fitting

Our optometrist will assess how well the lenses fit on your eyes, checking their movement, stability, and comfort. This ensures you enjoy clear vision while keeping your eyes healthy. There will be different fitting processes that are tailored for different types of specialty lenses.

Insertion & Removal

Insertion & Removal

You’ll be guided through proper techniques for inserting and removing your lenses safely. This hands-on training helps you build confidence and comfort in handling your lenses.

Handling & Replacement

Handling & Replacement

We’ll explain the best practices for cleaning, storing, and replacing your lenses on schedule. Following these steps helps prevent infections and keeps your eyes comfortable for daily wear.
