Interactive Cataract Surgery Simulation

Overview

This web application offers an interactive, anatomically simplified simulation of micro-incisional phacoemulsification cataract surgery. Designed as an educational introduction for medical students and residents, it outlines the basic structural phases of the procedure. Users are guided through localized tissue incisions, anterior capsule tearing, ultrasonic lens disassembly, residual cortical clearing, and final intraocular lens (IOL) insertion.

Operational Guide

• Surgical Field (Canvas): Represents the magnified anterior segment of the eye.
• Input Controls:
  • Mouse/Touch: Click/tap and drag directly inside the surgical field to navigate the active instrument tip.
  • Keyboard: Use the Arrow Keys (↑, ↓, ←, →) for precise micro-positioning. Press the Spacebar to activate the instrument's physiological function (e.g., thermal incision, ultrasonic power, suction).
• Interactive Pivot System: Once the corneal incision is made, subsequent instruments automatically pivot through that fixed entry point, simulating real-world surgical geometry.
• Automated Demonstration: Select "Play Demo" to view an automated, step-by-step performance of the procedure.
• Sonification: Enable the "Audio Feedback" option to experience simulated real-time audio cues reflecting active surgical mechanisms (ultrasonic energy delivery, aspiration pressure changes).

Simulated Surgical Phase Sequence:

1. Corneal Incision: Use a micro-keratome to establish a clear corneal entry port at the temporal limbus.
2. Continuous Curvilinear Capsulorhexis: Navigate a cystotome to create a controlled circular opening in the anterior lens capsule, maintaining constant tear tension.
3. Phacoemulsification: Activate the phaco probe with ultrasonic energy to fragment and emulsify the dense crystalline nuclear segments.
4. Cortical Aspiration: Use the irrigation/aspiration (I/A) probe to safely remove the soft, peripheral lens cortex while keeping the capsular bag inflated.
5. IOL Implantation: Direct the IOL injector into the capsular bag and deploy the folded acrylic lens, allowing its structural haptics to unfold and center.

Educational Scope & Disclaimers

This program serves as an introductory, schematic animation demonstrating the sequential phases of standard ocular microsurgery. It does not replicate complex physical tissue resistances, anatomical variations, fluidics dynamics (such as surge or chamber collapse), or acute surgical complications (like posterior capsule rupture). It is designed strictly for academic demonstration and is not certified for clinical preparation, diagnostic instruction, or surgical certification.
