Summary

The soft shell technique uses ophthalmic viscoelastic devices (OVDs) during vitrectomy to prevent perfluorocarbon liquid (PFCL) leakage into the subretinal space. This method aids retinal unfolding in proliferative vitreoretinopathy (PVR) cases.

Area of Science:

Ophthalmology
Retinal Surgery
Vitreoretinal Interface

Background:

Proliferative vitreoretinopathy (PVR) presents challenges during vitrectomy, particularly preventing perfluorocarbon liquid (PFCL) from entering the subretinal space through retinal breaks.
Ophthalmic viscoelastic devices (OVDs) are adhesive materials with potential to temporarily seal retinal breaks.

Observation:

A novel
soft shell technique
was employed during vitrectomy in five eyes with PVR.

Findings:

The soft shell technique, utilizing OVDs, effectively prevented PFCL from leaking into the subretinal space by sealing iatrogenic retinal breaks.
This technique facilitated retinal unfolding with PFCL, even in the presence of retinal folds and breaks.
All patients experienced improved visual acuity, with four eyes achieving retinal reattachment.

Implications:

The soft shell technique offers a viable method for utilizing PFCL during vitrectomy in PVR eyes.
This approach may improve surgical outcomes by preventing complications and aiding retinal detachment repair.
