LAF Workstation / Grade A Bench – Equipment Validation SOP

Standard Operating Procedure for Equipment Validation of LAF Workstation in Ophthalmics

Purpose: This SOP outlines the validation process for the LAF Workstation (Grade A Bench) used in the production of sterile ophthalmic products, ensuring compliance with regulatory standards and maintaining product quality.

Scope: This procedure applies to the validation of LAF Workstations employed in the aseptic filling and assembly of sterile eye drops and eye ointments within the production area.

Definitions:

  • LAF Workstation: A laminar airflow workstation designed to provide a sterile environment for aseptic operations.
  • Grade A Bench: A workspace that meets specific cleanliness and airflow requirements as per ISO 14644.
  • Validation: The process of establishing documented evidence that a system or process consistently produces a result meeting predetermined specifications.

Roles:

  • Validation Team: Responsible for planning and executing validation activities.
  • Quality Assurance: Ensures compliance with regulatory requirements and reviews validation documentation.
  • Production Personnel: Operate the equipment and provide input regarding its functionality and performance.

Lifecycle Procedure:

  1. Design Qualification (DQ): Ensure the equipment design meets user requirements.
  2. Installation Qualification (IQ): Verify that the equipment is installed correctly and according to specifications.
  3. Operational Qualification (OQ): Confirm that the equipment operates within specified limits.
  4. Performance Qualification (PQ): Validate that the equipment performs effectively in the production environment.

GDP Controls: Good Documentation Practices shall be followed throughout the validation process, ensuring all records are accurate, complete, and traceable.
