Abstract

Objective:To assess production of visible aerosol generation during clear corneal phacoemulsification surgery.

Methods:Aerosol generation was assessed during phacoemulsification.Typical settings were used and visible aerosol production was recorded using 4k camera. Aerosolisation was evaluated under various experimental settings:Two different phacoemulsification tip sizes(2.2mm,2.8mm),varying levels of corneal moisture,use of HPMC coating of cornea with static & moving tip.Results:Visible aerosol was noted during phacoemulsification with a 2.8mm tip.No visible aerosol was noted with a 2.2mm tip.Presence of visible aerosol is unrelated to corneal wetting.Visible aerosol production was abolished when HPMC was used.Visible aerosol was generated during movement of the 2.2mm tip towards the corneal wound.Conclusions:Visible aerosol production demonstrated with clear corneal phacoemulsification.It can be reduced using a 2.2mm tip and reapplying HPMC every minute during phacoemulsification.
