Purpose: To compare contrast sensitivity (CS) and glare in patients that received 4 different types of intraocular lenses with different optical edge design.
Methods: The study enrolled 120 patients (135 eyes) undergoing phacoemulsification and implantation of 4 different types of intraocular lenses with different optical edge designs. The procedure was performed by a single surgeon. The patients were tested at 2 months after surgery with ACV (Visual Capacity Analyzer, L2 Informatique, France) to measure CS and glare.
Results: In the patients who received LI61SE (13 eyes) and LI61U (46 eyes), we found no significant difference in glare but the patients who received LI61SE had more increased contrast sensitivity at spatial frequency 19 cpd in the monitor illuminator of 100 cd/m2 and 30 cd/m2. In patients who received MA60BM (47 eyes) and AR40e (29 eyes), we found the patients who received AR40e had more decreased glare and more increased CS at frequency 19 cpd in the monitor illuminator when it was set at 100 cd/m2 and 30 cd/m2.
Conclusions: The patients who received LI61SE had more increased CS at high spatial frequency than the patients who received LI61U. The patients who received AR40e had more decreased glare and more increased CS at high spatial frequency than patients with MA60BM. J Korean Ophthalmol Soc 48(2):259-265, 2007
