Purpose: To describe a method of epithelial debridement with the adjunctive use of topical cocaine for the treatment of symptomatic anterior basement membrane dystrophy (ABMD).
Methods: Retrospective consecutive chart review. Symptomatic patients with ABMD were treated with 4% topical cocaine followed by epithelial debridement. Preoperative and postoperative best-corrected visual acuities (BCVA), topography, subjective symptoms, complications, and evidence of disease recurrence were recorded.
Results: Thirty-three eyes of 27 patients were included. The average follow-up duration was 5 years (range, 1.3 months to 8 years). Fourteen patients (17 eyes) presented with recurrent erosion symptoms (group 1) and 13 patients (16 eyes) presented with reduced visual acuity from irregular astigmatism (group 2). Only 1 patient from group 1 experienced symptomatic recurrence of the corneal erosion. In this group, BCVA improved from a mean of 20/45 preoperatively to 20/38 at the last follow-up visit. In group 2, BCVA improved from a mean of 20/63 preoperatively to 20/32 at the last follow-up visit. No major recurrences were noted at the last follow-up visit in this group. No residual effect from the application of cocaine was noted in any of the eyes. Significant postoperative corneal haze occurred in 1 eye.
Conclusions: Topical cocaine-assisted epithelial debridement offers a simple and inexpensive method for treating patients with ABMD who experience recurrent corneal erosions and/or irregular astigmatism resulting in decreased visual acuity.

Chronic wounds are notoriously challenging to heal as they are often halted in their normal healing process. The concept of TIME (Tissue, Inflammation/Infection, Moisture imbalance, Epithelial edge advancement) has been widely utilized in clinical practice to prepare wound beds and promote healing, particularly in longstanding wounds. Traditional methods of wound bed preparation are often inadequate in healing chronic wounds or they may not be tolerated by patients.

An 83-year-old male with a history of radial keratotomy and laser-assisted in situ keratomileusis (LASIK) presented with symptoms of a non-resolving corneal ulcer in the right eye that had been present for five months. The patient was treated with antibacterial, antiviral, and antifungal medications over that period, with multiple recurrences that prompted referral to our tertiary center for management. Following a 48-hour cessation of all medications, a corneal biopsy was performed which grew .

First introduced over 20 years ago as a treatment for progressive keratoconus, the original "Dresden" corneal cross-linking (CXL) protocol involved riboflavin saturation of the stroma, followed by 30 min of 3 mW/cm-intensity ultraviolet-A (UV-A) irradiation. This procedure generates reactive oxygen species (ROS) that cross-link stromal molecules, thereby stiffening the cornea and counteracting the ectasia-induced weakening. Due to their large size, riboflavin molecules cannot readily pass through the corneal epithelial cell tight junctions; thus, epithelial debridement was performed.

Purpose: To investigate intrinsic phototransduction in the corneal epithelium and its role in intracellular and inflammatory signaling.
Methods: Optical imaging in isolated corneal epithelial cells (CECs) and debrided epithelia was combined with molecular, biochemical, pharmacological assays and gene deletion studies to track UVB-induced calcium signaling and release of cytokines, chemokines and matrix remodeling enzymes. Results from wild type mouse CECs were compared to data obtained from Opn5 and Trpv4 cells.
Purpose: To assess real-time intraoperative pachymetry changes occurring during corneal cross-linking (CXL) using microscope-integrated optical coherence tomography (Mi-OCT) and compare accuracy of various modalities of pachymetry assessment.
Methods: This was a cross-sectional observational comparative study including 45 consecutive patients with progressive keratoconus planned for CXL. Mi-OCT (RESCAN 700) was used to measure central corneal thickness (CCT) during four stages of CXL: before epithelial debridement, after debridement, after riboflavin instillation, and after ultraviolet irradiation.
