[Boston keratoprosthesis type 1]

Area of Science:

• Ophthalmology
• Biomaterials Science
• Transplantation Surgery

Background:

• Penetrating keratoplasty success relies on ocular surface health and immune privilege.
• Failure of corneal transplants leads to corneal blindness, necessitating alternative solutions.
• Artificial cornea research has advanced significantly, with keratoprostheses becoming primary options.

Purpose of the Study:

• To review global and personal experiences with the Boston keratoprosthesis type 1.
• To highlight its role in treating severe corneal blindness and high-risk conditions.
• To discuss recent improvements in design, technique, and management.

Main Methods:

• Review of clinical outcomes and experiences with Boston keratoprosthesis type 1.
• Analysis of changes in device design, surgical techniques, and postoperative care.
• Evaluation of complication rates and management strategies.

Main Results:

• The Boston keratoprosthesis type 1 is increasingly used for complex cases, including multiple failed corneal transplants.
• Recent modifications have substantially improved its success rate and reduced complications.
• It is now a viable primary procedure for specific indications, not just a last resort.

Conclusions:

• The Boston keratoprosthesis type 1 is a safe and effective alternative for certain corneal pathologies, significantly improving visual prognosis.
• Despite advancements, persistent complications require ongoing management.
• Further research and refinement are needed to optimize outcomes for all patients with corneal blindness.
