• A. True
• B. False
• C. Not specified
• D. Not applicable

Answer: (A)

Preservative-free artificial tears are recommended to improve comfort and support healing when the ocular surface is affected by HSV. The corneal epithelium can be irritated and fragile during HSV keratitis, and preservatives in many artificial tears can be toxic or irritating to damaged tissue. Using preservative-free formulations provides lubrication, reduces friction with blinking, and helps alleviate symptoms like burning, tearing, and photophobia without harming the healing surface. This is an adjunct to antiviral therapy, not a treatment for the virus itself, but it makes the eye more comfortable and can aid the healing environment.
