Abstract Details


The purpose of this study was to evaluate the results after Epithelial Bowman Keratectomy (EBK) and the safety of N-acetylcarnosine (NAC) lubricating eye drops as an accompanying treatment


Department of Ophthalmology, University Center of Ophthalmology and Oncology, Medical University of Silesia, Katowice, Poland


The analyzed group consists of 40 eyes of 20 patients with myopia and myopic astigmatism, who underwent EBK in the Refractive Surgery Unit. In the follow-up period NAC eye drops were instilled three times daily. There were 12 women and 8 man, mean age 25,4. Observation time was 6 months. Uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (BCDVA), keratometry, pachymetry, refractometry were examined. These measurements were carried out before the procedure, 1 month, 3 months and 6 months after the surgery.


Spherical equivalent before the procedure ranged from -1.5 to -5.0 D, mean 2.68 D. The differences in the analyzed group before and 6 months following the surgery were: refractometry -2,68 Dsph and -0,48 Dcyl before and 0,1 Dsph and -0,28 Dcyl after the procedure, UDVA 0,13 before and 1,0 after EBK, pachymetry 561,21 μm before and 509,21 μm after the procedure, maximum keratometry was 44,55 D before and 41,98 after the surgery.


According to our experience, refractive surgery procedure such as EBK in 6 month follow-up is characterized by high safety, efficiency and stability. NAC lubricating eye drops as an accompanying treatment was well tolerated by the patients, no local or systemic side effects were reported
