Title: Total Occlusive Ionic Silver-containing Dressing vs Mupirocin Ointment Application vs Conventional Dressing in Elective Colorectal Surgery: Effect on Incisional Surgical Site Infection
Brief Summary: The patients were randomized into 3 groups: those patients undergoing a ionic silver-containing dressing (ISD) (Group 1), those undergoing a Mupirocin ointment application (MOA) (Group 2) and those using a conventional dressing (Group 3) in the surgical wound after finishing an elective colorectal surgery.


Options:
A: Inclusion Criteria:

* Subject has a cataract and is expected to undergo unilateral clear corneal cataract surgery with phacoemulsification and implantation of a posterior chamber monofocal intraocular lens through an incision ≤ 3.5mm in width measured after IOL implantation using internal calipers.

Exclusion Criteria:

* Subject is currently receiving antineoplastic therapy
* Use of topical ocular steroids within 14 days and/or systemic steroids (excluding inhalants) within 30 days prior to surgery.
* Subject is an insulin-dependent diabetic or has background diabetic retinopathy (BDR), proliferative diabetic retinopathy (PDR) or compromised macular function

5. Patients with preoperative evidence of a current abdominal wall infection/surgical site infection from a previous laparotomy/laparoscopy
6. Patients that have received antibiotic therapy within the week prior to surgery
7. Patients with preoperative evaluation suggestive of an intra-abdominal process that would preclude full closure of the skin
8. Patients with a previously placed anterior abdominal wall mesh that is not planned to be completely removed during the planned procedure
9. Women who are pregnant or breast feeding or are considering becoming pregnant during the follow-up period
10. Mental incompetence as determined by the Investigator which would affect participation in the study
