INTRODUCTION

A Modular Ophthalmic Operation Theatre is designed to provide a highly controlled surgical environment where delicate eye procedures can be performed safely and efficiently. Ophthalmic surgeries such as cataract removal, retinal procedures, corneal transplants, glaucoma surgeries, and refractive treatments require exceptional cleanliness, precise environmental control, and strict infection prevention measures. Among all the systems that contribute to the performance of an operation theatre, the HVAC (Heating, Ventilation, and Air Conditioning) system plays one of the most critical roles.

The HVAC system is responsible for maintaining air quality, controlling temperature and humidity, regulating airflow, minimizing airborne contamination, and ensuring patient and surgeon comfort. Without a properly engineered HVAC system, even the most advanced operation theatre may struggle to maintain the sterile conditions necessary for successful ophthalmic procedures.
