Diamond burr superficial keratectomy in the treatment of visually-significant anterior corneal lesions

摘要: PURPOSE: To evaluate the efficacy and safety of diamond burr superficial keratectomy in treatment visually-significant anterior corneal lesions. METHODS: A retrospective review 23 eyes (23 patients). Pre- postoperative visual acuities refractions, slit-lamp biomicroscopic findings, incidence recurrence disease after were studied. RESULTS: Nineteen had map-dot-fingerprint basement membrane dystrophy 4 Salzmann's nodular degeneration. All patients presented with decreased vision, as well varying degrees glare, halos, monocular diplopia. Postoperative follow-up ranged from 3 to 39 months (mean 10.6 months), no original occurred within this period. This procedure improved best-corrected acuity 20/36 (LogMar 0.250) 20/24 0.076) by LogMar statistical evaluation (p<0.001) caused a statistically non-significant (p=0.232) myopic change mean refractive spherical equivalent (-0.36 diopter ± SD 2.28 preoperatively -0.71 2.26 postoperatively). Glare diplopia subjectively reduced or eliminated all patients. One patient mild stromal haze which bestcorrected 20/25 20/30. CONCLUSION: Diamond appears be an effective safe method removing opacities.
