Letter in reply to Letter to the Editor: Fat injection as a valuable tool for lower eyelid retraction management: a retrospective, observational, single blind, case-control study.

ABSTRACT

DEAR EDITOR We have read Dr Riccardo Fondrini and Colleagues commentary on our paper, and we are grateful for their remarks. We herewith would clarify the critical points mentioned about fat reabsorption and survival, along with the risk of periorbital chronic oedema as per the recorded outcomes in the presented case series. Lastly, we have unfortunately to disagree with the commentary's point related to recommended injection depth as it is mandatory to point out that in our experience the superficial injection of nano-fat is a crucial step for lower eyelid retraction management, otherwise a retraction may persist due to the untreated scar in the anterior lamella, thus missing the therapeutic goal that we aim to achieve.
