Analysis of clinical efficacy and safety of excimer laser technology in the treatment of bullous keratopathy

Abstract

AIM: To investigate the clinical efficacy and safety of phototherapeutic keratectomy(PTK)in the treatment of bullous keratopathy(BK).METHODS: A retrospective analysis of 60 cases(60 eyes)of BK patients from Department of Ophthalmology in our hospital October 2011 to July 2014 was undergone. Clinical data of all patients with treatment of PTK were analyzed. Best corrected visual acuity(BCVA), corneal curvature, corneal astigmatism, corneal thickness and corneal endothelial cell density(ECD), postoperative complications before and after surgery were compared.RESULTS: BCVA, corneal curvature, corneal astigmatism of patients before surgery were 0.05±0.01 and 37.02±5.38, 1.08±0.67D, which were significantly less than those of postoperative(respectively 0.45±0.13 and 46.27±7.02, 1.92±0.73D), the differences were statistically significant(all PPPCONCLUSION: Excimer laser technology has high safety in the treatment of bullous keratopathy, it should be promoted in clinical practice.
