SBK術后高階像差和視覺質量的臨床研究
[Abstract]:background The in-situ keratomileussis (SBK) of the first-layer laser in situ keratomileussis (SBK) is a new corneal refractive surgery in 2008. It has the advantages of fast postoperative visual recovery, low incidence of dry eye and wider treatment scope. The subject is subject to the weight of the refractive surgeon. View. Objective To observe and analyze the changes of high-order aberration (HO A), contrast sensitivity (CS) and glare contrast sensitivity (GS) in patients with myopia and to be combined with laser in situ keratomileussis, LSISI. K) The relationship between the high-order aberration and contrast sensitivity after SBK operation was discussed, and the visual quality of the post-operation of SBK was evaluated in a more comprehensive and comprehensive manner. supply Bed basis. The method uses its own front-back control and A case-control study was designed. From December 2010 to December 2011,78 patients with myopia were seen from the 91 Central Hospital of the PLA, where the SBK was the case observation group, the LASIK was the case control group, and the preoperative visual acuity (UCVA) and the best corrected vision (BS) were the best corrected visual acuity (BS). CVA), computer optometry, intraocular pressure, slit lamp, corneal topography The routine examination of the fundus and the like was performed. The NIDEK OPD SCAN wavefront aberration analyzer was applied before and after the operation for 1 week, January, March and June respectively. The pre-operative and postoperative 1-week,1-,3-and 6-month post-operative contrast sensitivity of the Otec6500 visual function tester were measured in a dark environment, respectively. Contrast sensitivity of degree of glare and glare. (Laser platform: NIDEK EC5000C X II ) is completed by the same physician The follow-up was maintained after the operation. The examination data was recorded in detail and the general statistical description was performed using the SPSS13.0 software, positive and negative, analysis of variance, independent sample t-test, Pearson correlation analysis iso-series Results 1. The best corrected vision, post-lens, central corneal thickness, corneal flap thickness, T. Sph, T. Trefoil, Total and intraocular pressure were compared in the preoperative SBK group and the LASIK group. There was a statistical significance (P 0.05).2. The visual acuity of the naked eyes in the SBK group and the LASIK group was poor and the difference was poor. The comparison of the two groups before and after the operation of the SBK group and the LASIK group There was a significant difference (P = 0.004).4. The total, High, T. Coma, T. Trefoil, T. Sph, and Sweig operations in the SBK group were statistically significant (P = 0.000, P = 0.000, P = 0, P = 0.000, P = 0.000, P = 0). The difference was statistically significant (P0.05). The difference was statistically significant (P0.05), and the difference was statistically significant (P0.05). Total was before operation,1 month after operation and 3 months after operation. The difference was statistically significant (P0.05).5. The increase of higher-order aberration in the two groups after operation: T. Sph compared with one month after the operation, with significant difference (P0.05); Total was 1 month after operation, and 6 months after operation. The difference was statistically significant (P0.05).6. Contrast sensitivity at the spatial frequencies of 1.5 c/ d, 6.0 c/ d, and 12.0 c/ d in the SBK group. The difference was statistically significant (P0.05) before and after the operation. The contrast sensitivity of 12.0c/ d and 18.0 c/ d bands was negatively correlated (r =-0.366, r =-0.311) and negative correlation (r =-0.366, r =-0.311) and negative correlation (r =-0.366, r =-0.311) and negative correlation (r =-0.366, r =-0.311). =- 0.381); and the clover difference and contrast sensitivity were not Conclusion 1. The visual quality of SBK is superior to LASIK. 2. Higher-order aberrations after SBK and higher-order aberrations after LASIK showed a trend of growth. The post-operation coma, spherical aberration, clover difference and total high-order aberration of BK were smaller than that of LASIK.4. SB
