Corneal scar after ulcer in a young patient demanding visual restoration in a timely fashion treated with PTK + topo-guided PRK

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. The manifest refraction was -3.25 -2.25 × 180 (20/20) in the right eye and was -2.00 esf -2.00 × 165 (20/80) in the left eye. The patient demands a solution in a reasonable time because of the need for functional vision and possible restoration of her binocular functions. The slitlamp examination revealed a corneal scar partially affecting the visual axis (Figure 1JOURNAL/jcrs/04.03/02158034-202412000-00016/figure1/v/2024-12-12T192825Z/r/image-tiff). Corneal topography revealed an irregular pattern and spectral-domain optical coherence tomography (OCT) examinations revealed scarring in the anterior stroma (Figures 2 and 3JOURNAL/jcrs/04.03/02158034-202412000-00016/figure2/v/2024-12-12T192825Z/r/image-tiffJOURNAL/jcrs/04.03/02158034-202412000-00016/figure3/v/2024-12-12T192825Z/r/image-tiff).
