KeraKlear XT Artificial Cornea

The KeraKlear® XT is an advanced, foldable artificial cornea designed to restore vision in patients with corneal opacity who are not suitable for traditional corneal transplantation. Implanted using a minimally invasive, non‑penetrating technique, KeraKlear XT creates a clear optical pathway while preserving the structural integrity of the eye.

Key Features

• Non‑penetrating keratoprosthesis – implanted within a stromal pocket, reducing the risks associated with full‑thickness corneal procedures 
• Foldable, biocompatible material – flexible acrylic polymer allows insertion through a small ~3.5 mm incision   
• Optimised optical zone – 4.0 mm central optic for clear visual access and fundus visibility 
• Peripheral fixation design – 12 holes enable secure suturing and long-term tissue integration 
• Variable thickness options (200–700 μm) – allows customised depth implantation depending on corneal pathology 
• Single-stage procedure – no donor cornea required

Clinical Benefits

• Restores functional vision by replacing the diseased anterior cornea while preserving the endothelium 
• Minimally invasive approach helps maintain corneal strength and reduces complication risk
• Eliminates dependence on donor tissue and associated rejection risks
• Rapid visual recovery in many patients following implantation 
• Compatible with future surgical options if needed

Indications

KeraKlear XT is intended for use in adult patients with corneal blindness or significant corneal opacity, including:

• Keratoconus
• Corneal scars and dystrophies
• Corneal edema
• Limbal stem cell deficiency
• Failed corneal transplants 

Technical Specifications

• Overall diameter: 7.0 mm 
• Optical zone: 4.0 mm 
• Material: Biocompatible foldable acrylic with UV inhibitor 
• Fixation: Peripheral holes (12-hole design) 
• Implantation depth: Typically 200–700 μm within corneal stroma 

Why KeraKlear XT

KeraKlear XT offers a modern alternative to conventional keratoplasty by combining minimally invasive surgical technique, predictable optical performance, and broad patient applicability, making it an effective solution for treating a wide range of corneal disorders.
