Abstract
Purpose: To compare postoperative visual acuity, spherical equivalent and contrast sensitivity of eyes implanted with either spherical C-flex(570C) or aspheric C-flex(970C) intraocular lenses (IOL). Methods: Forty eyes implanted with posterior chamber intraocular lenses were divided into two groups: C-flex(570C) (20 eyes) and C-flex(970C) (20 eyes). In these two groups, postoperative best corrected visual acuity (logMAR), spherical equivalent and contrast sensitivity was performed at one month and three months, postoperatively. Results: In the spherical group, the preoperative naked visual acuity was 1.250.46 (logMAR). The best corrected visual acuity at postoperative three months was 0.490.28. In the aspheric group, the preoperative naked visual acuity was 1.290.67. The bestcorrected visual acuity at postoperative three months was 0.390.30. There were statistically significant differences in best-corrected visual acuity between the preoperative and the postoperative three months results in the spherical IOL group and in the aspherical IOL group. There were no statistically significant differences in spherical equivalent between preoperative and postoperative onemonth results and between preoperative and postoperative three-month results in the spherical IOL group and the aspherical IOL group. In the aspherical IOL group, contrast sensitivity at postoperative one and three months were better in the all spatial frequency than in the preoperative scotopic condition. Conclusions: When we compared eyes implanted with the spherical C-flex(970C) with eyes implanted with the spherical C-flex (570C), there were no statistically significant differences in spherical equivalent or best corrected visual acuity. The aspherical IOL group showed better contrast sensitivity than did the spherical IOL group postoperatively at both one month and three months.
