Counting fingers at 30 cm was considered equivalent to Snellen value of 20/2000, which corresponds to a logMAR value of 2.0. Hand motion acuity was considered equivalent to a Snellen value of 20/20,000, which corresponds to a logMAR value of 3.0. Values are presented as mean ± standard deviation or number (%) unless otherwise indicated.
AMT, amniotic membrane transplantation; AS-OCT, anterior segment optical coherence tomography; IOP, intraocular pressure; logMAR, logarithm of the minimum angle of resolution.
