Clinical application study of blue light filtering intraocular lens

To evaluate the safety and effectiveness of clinical application of blue-light filtering intraocular lens. Methods 48 patients (96 eyes) who had age-related cataract and had accepted phacoemulsification were observed. One eye of the patients was implanted with the blue light filtering intraocular lens SN60AT Acrysof IOL and the other one was implanted with the conventional lens SA60AT Acrysof IOL. The vision, contrast sensitivity, chromatometry and complication were observed after operation. The period of follow-up survey was (2±2.5) months. Results There was no significant difference between the two groups (treatments) in term of vision, chromatometry and contrast sensitivity( P 0.05). However fewer people complained about glare and blueopsia in the SN60AT Acrysof group than those in the SA60AT Acrysof group. IOL-related complication was not found in the SN60AT Acrysof group. Conclusion The visual function and biocompatibility of the SN60AT Acrysof IOL and the SA60AT Acrysof IOL is the same. However, the subjective feeling is better and the object seen is more colorful in the patients implanted with SN60AT Acrysof IOL. SA60AT scry-sof IOL is much easier to be implanted than the SA60AT Acrysof IOL.
