At Shekhar Eye Research, we specialize in next-generation High Order Aberration (HOA) Scleral Lenses for patients who demand more than “acceptable vision.”

Many patients with keratoconus, irregular corneas, or post-surgical eyes continue to experience:

• Glare
• Halos
• Ghost images
• Starbursts
• Poor night driving vision
• Reduced contrast sensitivity

Even when visual acuity measures 6/6 or 20/20, the quality of vision may remain compromised.

HOA Scleral Lenses are designed to restore sharp, crisp, high-definition vision by correcting both lower-order and high-order aberrations.

High Order Aberrations are subtle optical distortions in the eye that cannot be corrected by standard glasses or conventional contact lenses.

These include:

• Coma
• Spherical aberration
• Trefoil
• Secondary astigmatism

They are especially common in:

• Keratoconus
• Post-LASIK irregular corneas
• Post-CXL eyes
• Post-keratoplasty patients
• Post-RK or trauma cases

At Shekhar Eye Research, we offer Chandra HOA Scleral Lenses — an advanced wavefront-guided scleral lens system.

These lenses are:

✔ Custom designed using wavefront aberrometry
✔ Individually optimized for each eye
✔ Manufactured in America with high-precision technology
✔ Designed to neutralize irregular optics
✔ Engineered for superior centration and rotational stability

Unlike traditional scleral lenses that only create a smooth tear layer, HOA scleral lenses actively correct residual internal optical distortions.

For highly irregular corneas or complex ocular surface disease, we offer Impression-Based Scleral Lenses.

Using an advanced impression technique:

• The exact contour of the eye is captured
• Customized digital design is generated
• Lens landing zone matches scleral shape precisely
• Mechanical bearing is minimized
• Comfort is maximized

This is particularly valuable for:

• Advanced keratoconus
• Stevens-Johnson syndrome
• Ocular surface disease
• Post-surgical distorted sclera
• Failed previous scleral lens fittings

HOA scleral lenses:

• Neutralize irregular astigmatism
• Reduce coma
• Improve contrast sensitivity
• Minimize glare and halos
• Provide stable, sharp vision

After procedures such as:

• LASIK
• PRK
• RK
• Corneal transplant
• CXL
• Intracorneal ring segments

Patients may experience:

• Night vision problems
• Glare
• Halos
• Fluctuating clarity

HOA scleral lenses restore optical precision without further surgery.

If you see:

• Starbursts around lights
• Ghost images
• Blurred night vision
• Poor contrast

HOA optics may dramatically improve visual quality.

• Superior visual sharpness
• Reduced glare and halos
• Improved night driving vision
• Better contrast sensitivity
• Stable and comfortable fit
• Long wearing comfort
• Customized for complex eyes

At Shekhar Eye Research, HOA scleral lens fitting includes:

1. Comprehensive ocular evaluation
2. Corneal topography
3. Wavefront aberrometry
4. Ocular surface assessment
5. Trial lens fitting
6. Impression-based design (if required)
7. Digital lens customization
8. Follow-up optimization

Each lens is individually crafted — never “stock.”

With decades of expertise in:

• Keratoconus management
• Scleral lens design
• Wavefront-guided optics
• Ocular surface disease
• Post-surgical visual rehabilitation

We combine science, artistry, and precision engineering.

Our philosophy:
Vision should not just be clear — it should be crystal sharp and comfortable.

You may benefit if:

• Glasses do not give clear vision
• Regular contact lenses are uncomfortable
• You have keratoconus
• You had eye surgery but still have glare
• You struggle with night driving

If you are living with distorted, hazy, or glare-filled vision, advanced HOA Scleral Lenses may be the solution.
