| 1 | Evaluation of anterior and posterior surfaces of the cornea using a dual Scheimpflug analyzer in keratoconus patients implanted with intrastromal corneal ring segments显示文摘AIM:To evaluate corneal parameters measured with a dual Scheimpflug analyzer in keratoconus patients implanted with intrastromal corneal ring segments(ICRS).METHODS:Fifty eyes of 40 keratoconus patients had Ferrara ICRS implantation from November 2010 to April2014.Uncorrected visual acuity(UCVA),best corrected visual acuity(BCVA),refraction,keratometry,asphericity,elevation,pachymetry,root mean square(RMS),spherical aberration and coma were studied.All patients were evaluated using a dual Scheimpflug system.RESULTS:The mean follow-up time after the procedure was 12.7mo.The mean UCVA improved from0.82 to 0.31(P<0.001);the mean BCVA improved from0.42 to 0.05(P<0.0001),the mean spherical refraction changed from-3.06 ±3.80 D to-0.80 ±2.5 D(P<0.0001)and the mean refraction astigmatism reduced from-4.51 ±2.08 D to-2.26±1.18 D(P<0.0001).The changes from preoperative to postoperative,in parameters of the anterior and posterior surface of the cornea,were statistically significant except the elevation posterior at the apex of the cornea and posterior asphericity.CONCLUSION:The implantation of Ferrara ICRS induces changes in both anterior and posterior surfaces of the cornea. | Leonardo Torquetti Carlos Arce Jesus Merayo-Lloves Guilherme Ferrara Paulo Ferrara Breenno Signorelli Armando Signorelli | 2016 | International Journal of Ophthalmology(English edition)2016，9，9： | 3 |
