摘要

BACKGROUND/AIMS: A prospective study evaluating the impact of intracorneal ring segment (ICRS) implantation on the quality of life of patients with keratoconus using the NEI-RQL (National Eye Institute Refractive Error Quality of Life) instrument. METHODS: Sixty-nine eyes of 42 keratoconus patients were implanted with the Keraring. All patients self-administered the NEI-RQL before and 4(1/2) to 8 months after surgery. The results were evaluated and analysed, along with best-corrected visual acuity (BCVA), refraction, contrast sensitivity, corneal topography and aberrometry preoperatively and 3 months postoperatively. RESULTS: There was a significant improvement in all NEI-RQL scales and the overall scale. Clarity of vision, appearance ranging from 25 to 50 preoperatively to 80 to 90 after surgery. Best spectacle-corrected visual acuity and binocular BCVA improved significantly, and there was a significant decrease in keratometric values, from 50.22 dioptres preoperatively to 46.27 dioptres postoperatively. Contrast sensitivity function improved postoperatively, especially at the frequency of 6 cpd. Low-order root mean square (RMS) improved after surgery, but high-order RMS did not. CONCLUSION: ICRS implantation not only improves the quantitative metrics such as visual acuity and refraction, but also has a positive impact on patients' quality of life.
