Background: Phototherapeutic keratectomy (PTK) has been increasingly used to treat severe recurrent corneal erosion syndrome (RCES) patients who do not respond to other treatments. However, the efficacy and complication of each study are currently uncertain due to varying rates.
Objectives: The objective of this study was to investigate the safety and efficacy of the PTK for recurrent corneal erosions.
Methods: This article performed a systematic literature research in Cochrane, Embase, PubMed, Scopus, and the Web of Science for the literature on PTK treatment of RCES until December 20, 2022. The extracted data including recurrence rate and the adverse event rate were used for meta-analysis.
Results: The recurrence rate was 18% (95% CI, 13%-24%) (129/700 eyes). Subgroup analysis showed that the RCE recurrence was 17% (95% CI, 9%-24%) after trauma and 22% (95% CI, 11%-32%) in the corneal dystrophy group. Treatment-related adverse events included subepithelial haze, hyperopic shift, and decrease of the best spectacle-corrected visual acuity. In this study, the incidence of these events was 13% (95% CI, 6%-21%), 20% (95% CI, 11%-28%), and 11% (95% CI, 5%-16%), respectively.
Conclusions: PTK represented a valuable treatment option for patients with recurrent corneal erosions, especially those with traumatic injuries, which had minimal side effects.

Efficacy and Safety of Secondary Surgical Treatment for Refractory Recurrent Corneal Erosion.
Cornea
January 2025
Eyejun Ophthalmic Clinic, Seoul, Republic of Korea; and.
Purpose: To investigate the efficacy and safety of secondary surgical intervention of combined phototherapeutic keratectomy (PTK) with alcohol delamination and peripheral anterior stromal puncture (ASP) for refractory recurrent corneal erosion (RCE).
Methods: This retrospective comparative study defined refractory RCE as cases persisting for more than 6 months after primary surgical intervention. A total of 115 eyes from 115 patients with refractory RCE, treated either with (n = 92) or without (n = 23) the secondary surgical treatment combining PTK and ASP between January 2021 and January 2023, were included.

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 .

Purpose: We demonstrate a novel approach for the definitive treatment of Lisch epithelial corneal dystrophy via an unintentionally staged alcohol keratectomy and intentionally targeted minor limbal excision with cautery.
Methods: A 46-year-old woman presented with visually significant corneal changes, suspected to be Lisch epithelial corneal dystrophy after clinical examination, anterior segment optical coherence tomography, and confocal microscopy. Alcohol keratectomy was performed with complete resolution, but there was visually significant recurrence at 2 years.
