Interactive Cataract Surgery Simulation

Overview

This web application provides an interactive, simplified simulation of a standard phacoemulsification cataract surgery, inspired by the video provided. It is designed as an educational tool for medical students, residents, and anyone curious about ophthalmology. The simulation guides the user through the critical steps of the procedure, from making the initial incision to implanting the new intraocular lens (IOL).

How to Use

• Canvas: The main circular area is the surgical field, providing a magnified view of the patient's eye.
• Controls:
  • Mouse/Touch: Click/tap and drag on the canvas to move the active surgical instrument.
  • Keyboard: Use the arrow keys (↑, ↓, ←, →) for precise instrument movement. Press the 'Spacebar' to activate the instrument's function (e.g., make an incision, apply phaco energy).
• Play Demo: Click the "Play Demo" button to watch an automated walkthrough of the entire surgical procedure. This is a great way to familiarize yourself with the steps.
• Reset: This button will restart the simulation from the beginning.
• Sonification: Toggle the "Sound" checkbox to enable or disable audio feedback for surgical actions. Sound is off by default.
• Information Panel: Keep an eye on the panel below the simulation to see the current step and the active instrument.

Surgical Steps Simulated:

1. Initial Incision (Side Port): Use the keratome to create a small incision on the cornea.
2. Capsulorhexis: Use the cystotome to create a circular opening in the anterior lens capsule. Follow the guide to create a perfect circle.
3. Phacoemulsification: Use the phaco probe to break up and aspirate the cataractous lens nucleus.
4. Cortex Aspiration: Use the I/A (Irrigation/Aspiration) probe to remove the remaining soft lens cortex.
5. IOL Implantation: Inject the folded intraocular lens into the capsular bag.
6. Finalizing: The IOL unfolds into place, completing the surgery.

Future Directions

This simulation is a foundational prototype. Future enhancements could include:

• Advanced Complications: Simulating potential surgical challenges like posterior capsular rupture or zonular dehiscence.
• More Instruments: Adding more tools like choppers for different phaco techniques (e.g., stop and chop).
• Parameter Control: Allowing users to adjust phaco machine settings (e.g., vacuum, power, aspiration flow rate).
• Scoring and Feedback: Implementing a scoring system to provide feedback on the user's performance and accuracy.
• Expanded Curriculum: Developing modules for other types of ophthalmic surgery.
