Setting
Methods
We analyzed 60 eyes of 30 patients aged 16–35 years who were treated at the Ophthalmology and Visual Sciences Department, Federal University of São Paulo, Brazil. The Visual Functioning Questionnaire (VFQ-25) and Short-Form 36 Questionnaire (SF-36) were used before intracorneal ring segment (ICRS) implantation and at 3, 6 and 12 months after surgical intervention.
Results
The mean corrected visual acuity improved from a mean of 0.32 ± 0.2 LogMAR (20/40) preoperatively to 0.14 ± 0.11 LogMAR (20/25) 1 year postoperatively (p = 0.001). The mean spherical equivalent varied from −7.24 ± 3.47 preoperatively to −4.13 ± 2.41 postoperatively (p = 0.001). The overall composite score for the VFQ-25 improved from 55.1 preoperatively to 80.4 1 postoperatively (P = 0.001). SF-36 showed statistically significant improvement in all scores. When analyzing the correlation between visual acuity and VFQ composite score, a significant correlation was found between both variables (Pearson’s correlation coefficient of −0.40, p = 0.001).
