| Abstract |
PURPOSE
To compare the clinical results of short-term visual acuity and quality of vision after implantation of a yellow-tinted blue light-filtering intraocular lens (IOL) (Acrysof IQ® SN60WF) and an clear ultraviolet (UV) light filtering IOL (enVista™ MX60) in the same patient. METHODS: 44 patients with bilateral cataract received an SN60WF in one eye and an MX60 in the other eye. All eyes were evaluated for refraction power and uncorrected visual acuity (UCVA) at preoperative and 1, 3 months postoperatively. At postoperative 3 months, corrected visual acuity, quality of vision (OQAS II®), contrast sensitivity (CGT 2000®) and visual field (Humphrey Field Analyzer®), and subjective patients' response to the degree of brightness were evaluated. Furthermore, glistening degree, intraocular stability, and posterior capsular opacification were examined. RESULTS: There were no significant differences in average refractive power or UCVA at 1 and 3 months (p > 0.05) between the two groups. At 3 months after cataract surgery, the quality of vision according to OQAS II®, the contrast sensitivity according to CGT 2000® with the glare either on or off, and visual field; showed no difference between the two groups (p > 0.05). Both IOLs had no glistening and posterior capsular opacity. The patients' response to the degree of brightness shows that MX60 (48.3%) has a higher degree of satisfaction. CONCLUSIONS: Yellow-tinted blue light-filtering IOL and clear UV light-filtering IOL had no difference in short-term visual acuity and quality of vision. Subjective brightness perception, however, was better with clear UV light-filtering IOL. |
