Corneal dystrophies may develop gradually from early onset in childhood and persist for years to decades. Visual impairment or repeated ocular irritations caused by corneal dystrophies severely affect the quality of life. Although various surgical treatment options are indicated for adult patients, the treatment plan for pediatric patients remains unclear. Herein we describe clinical observations of phototherapeutic keratectomy for corneal epithelial-stromal dystrophies in three pediatric patients (five eyes). Corneal opacities were successfully removed, and visual acuity was greatly improved in all operated eyes. The procedure of phototherapeutic keratectomy seems to be feasible in the treatment of corneal epithelial-stromal dystrophies in c hildren, with advantages of minimal invasion and good visual outcomes.

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.

Aim: To evaluate the clinical efficacy and feasibility of superficial corneal opacities treated by excimer laser phototherapeutic keratectomy (PTK) combined with small incision lenticule extraction (SMILE)-derived corneal stromal lenticule transplantation.
Methods: A retrospective interventional case series of nine patients aged 12-59y with superficial corneal opacity caused by different pathologies who underwent standardized PTK combined with SMILE-derived corneal stromal lenticule transplantation was examined. Lenticule patches were fixed with fibrin glue.

To report a novel application within the USA of excimer ablation for the normalization of central corneal refractive irregularity, combined with higher fluence CXL in the effective management and visual rehabilitation of progressive keratoconus. 17 consecutive cases with progressive keratoconus were treated with corneal surface excimer laser ablation normalization using topography-guided (Contura) myopic ablation for customized corneal re-shaping with a 6 mm optical zone. The epithelial removal was accounted for by adding a -2.

A 23-year-old woman was referred for low visual acuity in the left eye after a corneal ulcer associated with contact lens use 2 years previously. The patient had a history of contact lens use, reported use of antibiotic eye drops with improvement of infection, and subsequent scarring. There were no comorbidities.

Introduction: Phototherapeutic keratectomy (PTK) is a treatment for recurrent corneal erosion syndrome (RCES). The aim of this study was to investigate whether deeper ablations yielded greater success rates.
Methods: Retrospective case notes review with prospective patient-reported outcome measures for all patients who had undergone PTK for RCES at a single tertiary referral unit.
