Objective/Purpose
To evaluate whether blue-light-blocking intraocular lens implantation affects the sleep quality of cataract patients

Materials/Patients
Patients of bilateral cataract with over than level N3 (LOCS II) nucleus hardness could be included in this study, then they do cataract phacoemulsification followed by blue-light-blocking intraocular lens(IOLs, SN60WF, Alcon Laboratories, USA) implantation.

Methods
Patients were contacted in site before cataract surgery and followed by telephone at least 2 months later after second-eye surgery, and the Pittsburgh Sleep Quality Index(PSQI) questionnaires were administered to evaluate the sleep quality.

Results and Conclusion
40 patients which including 26 females (65%) and 14 males (35%) have been included in this study. The median age of all patients was 74 years(IR 70 to 78). The median PSQI globe score were 7 before surgery and 4 after surgery (Z=-2.121, P=0.037).More specifically, there were significant differences on subjective sleep quality (Z=-2.064, P=0.045), sleep duration (Z=-2.037, P=0.047) and daytime dysfunction (Z=-2.142, P=0.034) when compared between before and after surgeries.The ratio of poor sleepers (PSQI>5) reduced significantly after surgery (c2=14.532, P=0.000).
Conclusions Blue-light-blocking IOL had a significantly beneficial effect on the sleep quality of cataract patients.
