We read with great interest the article entitled “Prospective comparison of two suturing techniques of amniotic membrane transplantation for symptomatic bullous keratopathy” by Altiparmak and associates. The authors concluded that modified amniotic membrane transplantation (AMT) suturing technique has a similar epithelialization rate to standard AMT suturing to the cornea.

The donor of amniotic membrane should be screened to exclude risk of transmissible infections such as human immunodeficiency virus (HIV), hepatitis B virus, hepatitis C virus, and Treponema pallidum infections. However, the authors did not mention any screening test in their article. We believe that the authors had excluded the donors with positive serologic tests. Transmission of these infections to recipient patients may cause legal issues.
