This study aimed to investigate visual field (VF) progression in open-angle glaucoma (OAG) subjects who had a history of refractive corneal ablation surgery (RCAS). Retrospective study. The medical records of 21 subjects who had a history of refractive corneal ablation surgery (RCAS group) and 36 patients who had myopia without a history of RCAS (non-RCAS group) were reviewed. VF progression was determined by the non-parametric progression analysis (NPA) method. VF progression and clinical characteristics were compared between the two groups. For the RCAS group, refractive regressions were analysed. The mean follow-up periods were 4.5 years and 5.5 years for the RCAS and non-RCAS groups, respectively. More glaucoma subjects in the RCAS group (57.1%) had likely VF progression than in the non-RCAS group (25.0%) (p = 0.01). The RCAS group had a significantly lower percentage of IOP reduction with anti-glaucoma medication than the non-RCAS group (p = 0.037). Eyes with likely VF progression had a higher incidence of refractive regression (91.7%, 11/12) than eyes without it (33.3%, 3/9). Among subjects whose eyes had refractive regression, 78.6% (11/14) had likely VF progression, and 21.4% (3/14) did not (p = 0.016). The VF progression in OAG after RCAS was faster than that of myopic OAG without RCAS. Anti-glaucoma treatment should be actively enhanced in clinical practice.
