Brief Summary
A cataract is a clouding of the crystalline lens inside the eye, which leads to a decrease in vision. It is the most prevalent, treatable cause of visual impairment and blindness in the world. Cataract surgery with an intraocular lens (IOL) implant is one of the most common and thought to be the most effective surgical procedure in any field of medicine. In this trial, the investigators aimed to evaluate the effect of cataract surgery on circadian rhythm and sleep as well as the effect of the blue light transmission characteristics of the implanted IOL on sleep.

Outcome Measures
Primary Outcomes (3)
Change from Post-illumination pupil response (PIPR)
3 months before the surgery and 3 months after the surgery
Change from Objective sleep quality:actigraphy
3 months before the surgery and 3 months after the surgery
Change from Subjective sleep quality: PSQI

Study Arms (2)
Neutral IOL
EXPERIMENTALPhacoemulsification cataract surgery is performed with neutral IOL implantation.
Blue-blocking IOL
EXPERIMENTALPhacoemulsification cataract surgery is performed with blue-blocking IOL implantation.
Interventions
The phacoemulsification lens removal cataract surgery is performed with neutral IOL.implantation
The phacoemulsification lens removal cataract surgery is performed with blue-blocking IOL.implantation.
All patients received subconjunctival dexamethasone (2 mg) during surgery, and all surgeries were performed under general anesthesia.
viscoelastic materials are used to protect corneal endothelial cells.
