Results

Improved ocular comfort was reported 97%. Mean ocular discomfort score decreased from 3.30 to 1.24 while mean photophobia score decreased from 3.15 to 1.27. Mean LogMAR BCVA improved from 0.42 to 0.25. The AM and SCL remained in position for 94% of eyes. Complete corneal epithelialization was observed in all eyes immediately after SCL removal.

Baseline Characteristics

Methods. Prospective, non-comparative, interventional case series. Thirty-four (34) eyes of 30 patients with ocular surface disease (OSD) variably characterized by tear deficiency, superficial punctate keratopathy (SPK), and corneal epithelial defects

Participant flow

Enrolled eyes underwent ocular surface rehabilitation by DAMAT utilizing processed amniotic membrane (AmnioTek C, ISP Surgical, Boston, MA). The DAM was retained using conventional soft contact lenses (SCL) for 2 to 3 weeks after which the SCL was removed. Patients were followed up 2 months after AM/SCL application.

Adverse events

Eight of 34 (24%) eyes required repeat DAMT after SCL removal due to recurrence of epithelial defects or ocular discomfort. One (3%) eye required AM/SCL reapplication due to spontaneous displacement. One (3%) eye required AM/SCL removal due to intolerable foreign body sensation. No serious adverse reactions related to either AM or SCL were observed.

Outcome measures

Main outcome measures: Ocular discomfort score, photophobia score, best-corrected visual acuity (BCVA), AM/SCL retention, corneal re-epithelialization and quality after SCL removal, reapplication rate and adverse events.
