Comparison of high order aberration after conventional and customized ablation in myopic LASIK in different eyes of the same patient 总被引:4,自引:0,他引:4
Purpose: To verify whether there exists any difference in higher order aberrations after undergoing myopic LASIK (laser in situ keratomileusis) with conventional ablation and customized ablation in different eyes of the same patient. Methods: This was a prospective randomized study of 54 myopic eyes (27 patients) that underwent LASIK using the Nidek EC-5000 ex-cimer laser system (Nidek, Gamagori, Japan). Topography-guided customized aspheric treatment zone (CATz) was used in the first eye of the patient (study group) and the other eye of the same patient was operated on with conventional ablation (control group). Higher order aberrations [root-mean-square (RMS) in the 5-mm zone] of both groups were observed with the Nidek OPD-Scan aberrometer before and 3 months after LASIK. Preoperative mean refractive error was similar between two eyes of the same patient (t=?0.577, P>0.05). Results: Preoperatively, higher order aberrations (RMS in the 5-mm zone) in the CATz ablation and conventional groups were (0.3600±0.0341) μm and (0.2680±0.1421) μm, respectively. This difference was not statistically significant (t=1.292, P>0.05). Three months after LASIK, higher order aberrations (RMS in 5-mm zone) in the CATz ablation and conventional groups were (0.3627±0.1510) μm and (0.3991±0.1582) μm, respectively. No statistically significant difference was noted between pre- and postoperative higher order aberrations in the CATz group (t=?0.047, P>0.05). However, a statistically significant increase in higher order aberrations was observed after conventional ablation (t=?5.261, P<0.05). A statistically sig-nificant difference was noted in the increase of higher order aberrations after LASIK between groups (t=?2.050, P=0.045). Con-clusion: LASIK with conventional ablation and topography-guided CATz ablation resulted in the same BSCVA (best specta-cle-corrected visual acuity) 3 month after LASIK. Higher order aberrations were increased, but the increase of higher order ab-errations after customized ablation treatment was less than that after conventional ablation. 相似文献

There is evidence that national scientific journals are important for local communities despite their limited audience due to national languages and topics, like in pedagogy. However, it is not easy to assess the level of scientific rigour of local journals, as most do not have available scientometric data and are often published in minority languages. We hypothesize that a possible manifestation of a latent trait of inner authenticity of the scientific journal (meaning the journal is accepted by a community interested in developing the field which conducts internationally accepted research) could be H-index of the editorial board members. To test this approach, we evaluated H-index and gender of editorial board members (n = 490) from 17 Czech and Slovak national science-oriented scientific pedagogical journals which were not indexed or indexed in Erih+ or Scopus, and compared this with the five lowest-rated journals from the same field indexed in the Web of Science (WoS) database. The H-index of editorial board members was somewhat higher in indexed journals with those from WoS showing higher scores, and the number of board members with no discernable H-index was far greater in non-indexed journals. Editorial boards of journals indexed in WoS were mostly male, compared to a dominance of women on boards of non-indexed journals. Acknowledging the limited sample, it appears that the H-index of editorial board members may be a way to value national scientific journals. 相似文献
