AI Article Synopsis
- The study aimed to assess the protective effect of Biolon (a 1% sodium-hyaluronate solution) on the corneal endothelium during the harvesting of donor corneas.
- It involved a randomized, double-blind trial with 120 corneas from 60 donors, comparing endothelial cell density (ECD) between corneas harvested with and without the injection of an ophthalmic viscosurgical device (OVD).
- Results indicated that the OVD group had a higher ECD (2839 cells/mm²) compared to the control group (2748 cells/mm²), suggesting that OVD may help prevent mechanical damage, although further research is necessary before making it a standard practice.
Article Abstract
Purpose Of The Study: To evaluate the protective effect of Biolon (sodium-hyaluronate 1%) use on corneal endothelium, during donor's corneal harvesting.
Materials And Methods: A prospective, randomized, double blind, comparative study was performed on 120 corneas donated from 60 donors. One cornea from each donor (n = 60) was harvested using intracameral injection of ophthalmic viscosurgical device (OVD), and the fellow cornea with no use of OVD (n = 60, control group). Endothelial cell density (ECD) values were obtained at the center of each corneal graft with a specular microscope one day after harvesting.
Results: ECD in the OVD group were 2839 ± 412.5 cells/mm(2) and in the control group 2748 ± 429.7 cells/mm(2). (p = 0.03). Distribution curve of the difference in ECD between the OVD and no OVD eyes showed that 47% of the donors had > 100 cells/mm2 difference, and 32% of donors had >200 cells/mm(2) difference in favor of the OVD group.
Conclusions: Intracameral OVD injection during corneal graft harvesting may protect the endothelium from the mechanical damage induced during the procedure. Further investigation is needed before routine the use of intracameral OVD should be considered in this setting.

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.

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.
