Brief summary
The main goal of the sub-incisional pocket (SIP) is to provide a wound seal option during corneal surgery. This retrospective cohort study aims to report the efficacy and safety of SIP among eyes undergoing routine cornea surgery as well as to determine factors that could be correlated with wound seal.
Interventions
PROCEDURESub-Incisional Pocket
The sub-incisional pocket (SIP) consists of two (2) adjacent, non-penetrating, incisions using a 2.2 mm triangular blade placed just anterior to the limbus. This is followed by a penetrating clear corneal incision using the same 2.2 mm blade located immediately anterior to the SIP.

| Measure | Time frame | Description |
|---|---|---|
| Wound seal of participants assessed with the CCI-SIP 4-point ordinal scale by pressure with cotton tip pledget at post-operative day 1. | 6 Weeks | Clear corneal incision-Subincisional pocket (CCI-SIP) wound seals were graded on a 4-point ordinal scale: Grade 4, Fully formed AC after removal of all instrumentation with no hydration maneuvers; Grade 3, Flat AC after instrumentation removal, AC reformed after hydrating the side-port incisions only; Grade 2, Flat AC reformed after hydrating both side ports and SIP; and Grade 1, flat AC reformed after hydrating the side ports, SIP and CCI lateral walls. A higher wound grade denotes better wound sealability. |
