Hyperdry amniotic membrane (AM) patching effectively treated corneal perforations and glaucoma filtering bleb leaks. This novel surgical method shows promise for vision-threatening ocular conditions with no adverse effects.

Area of Science:

Ophthalmology
Regenerative Medicine
Biomaterials Science

Background:

Corneal perforations and glaucoma filtering bleb leaks are serious conditions requiring prompt treatment.
Traditional treatments may have limitations or complications.
Amniotic membrane (AM) has demonstrated therapeutic potential in ocular surface reconstruction.

Observation:

A prospective case series evaluated hyperdry amniotic membrane (AM) patching for five eyes with corneal perforations or glaucoma filtering bleb leaks.
The hyperdry AM was prepared using infrared rays and microwaves, sterilized, and attached with tissue adhesive.
A therapeutic hydrogel contact lens was used as a bandage post-procedure.

Findings:

All five cases of corneal perforations and glaucoma filtering bleb leaks were successfully repaired within 21 days.

No significant adverse effects were observed.

No recurrence of bleb leaks or corneal perforations was reported.

Implications:

Hyperdry AM patching is a viable and promising surgical technique for managing corneal perforations and glaucoma filtering bleb leaks.
This method offers a potentially safe and effective alternative for vision-threatening ocular conditions.
Further research may explore the long-term efficacy and broader applications of this AM preparation and delivery method.
