A Novel, Delicate, And Portable Multi-Purpose Electro-Automatic Microsurgical System For Capsulorehexis, Corneal Grafting, And Glaucoma Surgery: Design And Functional Evaluation

To evaluate the efficacy of a novel, portable, electro-automatic microsurgical system designed for high-precision anterior segment procedures. The primary objective is to automate the most delicate steps in three key surgeries: 1) Achieving a standardized, circular capsulorhexis in cataract surgery, 2) Ensuring precise tissue cutting for corneal grafting (endothelial and penetrating keratoplasty), and 3) Facilitating controlled micro-incisions in glaucoma surgery. This multi-purpose system aims to reduce human error, minimize surgical trauma, and provide a portable alternative to bulky, expensive laser systems.

Experimental research and surgical simulation conducted at Beheshti university The study involved performance testing on porcine eyes and synthetic ocular models, comparing the electro-automatic system's precision against manual techniques in cataract, glaucoma, and corneal transplant scenarios.

The electro-automatic microsurgical system features a delicate, portable console with high-frequency micro-tips for precise tissue management. Methods included: a) Performing automated capsulotomies to measure diameter consistency and tensile strength, b) Executing micro-trephination for corneal grafting to evaluate edge quality, and c) Creating standardized drainage channels for glaucoma surgery. We measured the system’s portability, response time of the automatic feedback mechanism, and the thermal impact on surrounding tissues compared to traditional manual instruments.

The electro-automatic system demonstrated superior precision, achieving 100% successful circular capsulorhexis with a mean deviation of <0.05 mm. In corneal grafting models, the device provided significantly smoother graft edges compared to manual trephines, potentially improving graft-host integration. Glaucoma micro-incisions were highly reproducible with minimal collateral tissue damage. The system's portability allowed for rapid setup in under 5 minutes. No mechanical failures were recorded, and the "delicate" tip design ensured safe operation even in narrow anterior chambers.

This portable electro-automatic microsurgical system represents a significant leap in ophthalmic instrumentation. By providing a multi-purpose platform for cataract, cornea, and glaucoma surgeries, it offers a cost-effective and precise alternative to manual or femtosecond laser techniques. Its delicate handling and automated feedback improve surgical safety and outcomes. This system is ideally suited for both high-volume centers and remote surgical settings, standardizing complex maneuvers across multiple sub-specialties in ophthalmology.
