Introduction: Cataract surgery is one of the most commonly performed surgical procedures worldwide. Intraoperative and postoperative complications of cataract surgery include posterior capsule rupture, retinal detachment, suprachoroidal hemorrhage, cystoid macular edema, endophthalmitis, and intraocular lens dislocation. As corneal perforation is rarely related to cataract surgery, we report a case of intraoperative iatrogenic corneal puncture that led to a full-thickness laceration that was managed without severe complications.

November 2024

From the Tennent Institute of Ophthalmology, Gartnavel General Hospital, Glasgow, United Kingdom (Henry, Lockington); James Weir Fluids Laboratory, Department of Mechanical and Aerospace Engineering, University of Strathclyde, Glasgow, United Kingdom (Castro, Rycroft, Syntouka, Oliveira); Advanced Materials Research Laboratory, University of Strathclyde, Glasgow, United Kingdom (Belkessa, Sillars); Edinburgh Complex Fluids Partnership (ECFP), SUPA and School of Physics & Astronomy, The University of Edinburgh, Edinburgh, United Kingdom (Silva).

Purpose: To evaluate how temperature affects the rheology of common ophthalmic viscosurgical devices (OVDs) and clinical implications.

Setting: Tennent Institute of Ophthalmology, Glasgow, with Department of Mechanical and Aerospace Engineering, and Advanced Materials Research Laboratory, University of Strathclyde, Glasgow, United Kingdom.

Design: Laboratory pilot study.

To protect the corneal endothelium, various ophthalmical viscoelastic devices (OVDs) are used during cataract surgery. In this study, we compared two sodium hyaluronate-based OVD, the bacteria-derived FIDIAL PLUS OVD (test) with the animal-derived IAL-F OVD (reference) during the surgical procedure. Fifty patients with bilateral cataract participated in the study: 50 eyes randomly received FIDIAL PLUS and 50 eyes received IAL-F (ratio 1:1).

Objective: To present six cases exhibiting transient anterior subcapsular vacuolar lens opacities following early postoperative Tanito microhook trabeculotomy (TMH) performed by the same surgeon.

Methods: Six patients who underwent lens-sparing TMH at Meizankai Shimizu Eye Clinic from November 2021 to May 2023, and developed anterior subcapsular vacuolar lens opacities postoperatively were reviewed. Detailed records of surgeries, follow-up findings were collected and reported.
