Scleral Lenses: Clear Vision for Irregular Corneas When Nothing Else Works
"I've tried everything. Glasses don't work. Regular contacts pop out. The doctor says my cornea is too irregular. Is there anything left to try before surgery?"
If this sounds familiar, you're not alone. Patients with keratoconus, post-surgical complications, or other corneal irregularities often arrive at our clinic feeling defeated after years of unsatisfactory vision correction attempts.
The good news? There's often a solution they haven't tried yet: Scleral lenses.
What Makes Scleral Lenses Different?
Unlike regular contact lenses that sit directly on the cornea, Scleral lenses are larger and rest on the white part of the eye (the sclera). They vault completely over the cornea, creating a smooth optical surface regardless of the cornea's shape.
Think of it this way: if your cornea has become cone-shaped or irregular, regular glasses and contacts try to work with that irregular surface. Scleral lenses essentially bypass it entirely, creating a new, perfectly smooth front surface for light to pass through.
The space between the lens and cornea is filled with preservative-free saline, which serves multiple purposes: it provides constant hydration, cushions the cornea, and creates the optical correction.
Who Benefits from Scleral Lenses?
Scleral lenses can be life-changing for people with:
Keratoconus: The most common reason patients seek Scleral lenses. As the cornea progressively thins and bulges, glasses become ineffective and regular contacts become uncomfortable or impossible to fit. Scleral lenses provide stable, clear vision even in advanced cases. Our keratoconus management programme includes comprehensive Scleral lens fitting.
Post-LASIK complications: Some patients develop corneal irregularities, ectasia, or severe dry eye after refractive surgery. Scleral lenses can restore quality vision when other options fail.
Pellucid marginal degeneration: Similar to keratoconus but affecting a different part of the cornea, this condition responds excellently to properly fitted Scleral lenses.
Severe dry eye syndrome: The fluid reservoir beneath the lens keeps the cornea constantly bathed in moisture, providing relief for patients with severe dry eye who cannot tolerate regular contacts.
Corneal scarring or transplants: After corneal injuries, infections, or transplant surgery, the corneal surface may be too irregular for conventional correction. Scleral lenses can mask these irregularities.

Why Fitting Scleral Lenses Requires Expertise
Scleral lenses aren't something you can order online or get fitted at any optical shop. The fitting process is complex and requires specialised equipment, training, and experience.
Here's what proper fitting involves:
Detailed corneal mapping: Using advanced topography and tomography, we create a detailed 3D map of your cornea's shape, thickness, and curvature at thousands of points.
Scleral shape assessment: The white of the eye isn't uniformly curved -- it has its own topography. Understanding this is crucial for comfortable lens settling.
Trial lens evaluation: We use diagnostic lenses to assess fit, clearance, and vision before ordering your custom lenses.
Custom lens design: Based on all this data, lenses are custom-manufactured to your exact specifications. No two pairs are alike.
Fitting verification: Once your lenses arrive, we verify the fit, check corneal clearance with specialised equipment, and make adjustments if needed.
Common Concerns About Scleral Lenses
"Won't such large lenses be uncomfortable?"
Surprisingly, most patients find Scleral lenses more comfortable than smaller rigid lenses. Because they rest on the less sensitive sclera rather than the cornea, and because the fluid cushion prevents any rubbing, many patients forget they're wearing them.
"Are they difficult to insert and remove?"
There's a learning curve, yes. We provide thorough training and don't let patients leave until they're confident with insertion and removal. Most people get comfortable within the first week. Special tools like plungers make the process easier.
"How long can I wear them each day?"
Most patients can comfortably wear Scleral lenses for 12-16 hours daily. The fluid reservoir keeps the eye hydrated throughout wear, unlike regular contacts that can dry out.
"What about maintenance?"
Scleral lenses require proper cleaning and storage, but the routine is straightforward. We provide detailed instructions and recommend specific solutions. With proper care, lenses typically last 1-2 years before needing replacement.
The Vision Results: What to Expect
For many patients with irregular corneas, Scleral lenses provide the clearest vision they've experienced in years -- sometimes ever.
Because the lens creates a perfect optical surface, it can correct not just the refractive error but also the higher-order aberrations that cause halos, ghosting, and multiple images -- symptoms that plague keratoconus patients and are impossible to correct with glasses.
Many patients report being able to drive at night again, read without strain, and perform detailed work that had become impossible. The improvement in quality of life is often dramatic.
Scleral Lenses vs. Corneal Transplant
Some patients are told that a corneal transplant is their only option. While transplants are sometimes necessary, Scleral lenses often provide an effective alternative that:
• Avoids surgery and its associated risks
• Requires no recovery time
• Can be adjusted as your cornea changes
• Has no risk of rejection
• Often provides equal or better vision
Even patients who eventually need a transplant often benefit from Scleral lenses afterwards, as transplanted corneas frequently have irregular astigmatism.
