Dear Editor:

Novel corona virus pandemic has become a major health issue faced by us in 2020. There has been a substantial reduction in outpatient visits and elective surgeries in the field of ophthalmology. Multiple safe practice protocols have been developed by various organizations.[1] We describe a slit lamp modification that enhances safety during patient evaluation [Figure 1].

Slit lamp evaluation is one of the most inevitable examinations in ophthalmology, but the distance between the patient and the examiner is lesser than 1 meter (6 feet). Smartphone-assisted slit lamp photography, using adaptors, has gained popularity in recent times.[2] The smartphone is connected to the slitlamp using an adaptor. An android/ios application that converts a smartphone to a IP camera (It can acquire images and transfer in local network) is downloaded from playstore/appstore.[3] Now the viewing screen (laptop or desktop) and smartphone are connected to the same WLAN). The application is launched; auto-generated IP address is copied to the browser in the viewing screen. The examiner just needs to operate the joystick of the slitlamp and can view live images on the screen. This modification allows the examiner to be more than 1 meter from the patient, thus avoiding possible aerosol mediated infection.

This simple modification can help us continue our routine OPD, simultaneously taking care of the aspect maintaining safe distance with the patient.
