Service Overview
When irregular corneal curvature makes standard glasses ineffective, standard optical tracking fails to deliver sharp vision. Our advanced clinic specializes in high-precision medical refraction and specialty contact lenses tailored for thinned, distorted, or post-surgical eyes. We offer dedicated Scleral Lens fitting, flexible Hybrid Lens fitting, and customizable gas-permeable Boston Lens designs. By bypassing surface distortions, these customized systems establish a smooth path for light to restore your daily visual clarity.
What It Covers
Scleral Lens Fitting
Customizing large-diameter rigid gas permeable systems that vault completely over the thinned cornea to rest safely on the white sclera.
Hybrid Lens Fitting
Designing advanced lenses that combine a crisp, gas-permeable rigid center with a soft, comfortable outer skirt layer.
Boston Lens Customization
Formulating high-oxygen polymer gas permeable designs to correct complex prescription parameters precisely.
Fluid Reservoir Staging
Engineering a constant layer of sterile saline beneath the lens dome to keep compromised tissues continually hydrated.
Who It Is For
Advanced Ectasia Profiles
Keratoconus individuals whose progressive structural changes can no longer be corrected using commercial soft options.
Post-Graft Surgical Patients
Individuals seeking to eliminate high irregular astigmatism following a corneal transplant procedure.
Irregular Curvature Challenges
Anyone whose medical refraction reveals poor visual acuity with standard glasses due to surface scars.
How It Works
Specialized Refraction
A corneal specialist utilizes high-resolution digital topography and manual diagnostic trial sets to map out your best-corrected vision boundaries.
Lens Type Selection
Based on your eye's shape, we determine whether a stable Boston gas-permeable lens, a soft-skirted hybrid lens, or a wide scleral lens fitting is required.
Precise Customization
The multi-dimensional scan data is sent to a specialized laboratory to produce your highly customized, micron-aligned lenses.
Why Choose Us
Our specialty cornea department features dedicated optometrists and refractive specialists explicitly credentialed in complex anterior segment restoration. We utilize advanced digital mapping to customize your Scleral Lens fitting or Hybrid Lens fitting parameters safely without causing physical friction to delicate tissue layers. By matching premium materials like the Boston Lens with custom medical refraction protocols, we ensure optimal comfort and exceptional visual stability.
Frequently Asked Questions
How does a specialized Hybrid Lens fitting differ from a standard soft lens?
A hybrid design blends the crystal-clear optics of a rigid gas-permeable center with the easy wearability of a soft outer lens skirt.
Why is a regular eye exam insufficient for irregular corneal curvature?
Standard refraction only checks basic focal points; custom medical refraction maps structural irregularities to calculate a customized lens shell shape.
Can a wide scleral fitting safely protect an older corneal transplant graft?
Yes, because the lens arches completely over the tissue boundary and rests on the sclera, it prevents physical friction against the sensitive graft.
