Impact of Cataract Surgery on Sleep in Patients Receiving Either Ultraviolet-Blocking or Blue-Filtering Intraocular Lens Implants

Abstract

Overall sleep quality and sleep latency improves after removal of cataract irrespective of the type of IOL implanted. These data show that implantation of BF-IOL does not have a negative impact on the sleep-wake cycle.

Ultraviolet or blue-filtering intraocular lenses: what is the evidence?

“…Sleep quality improved significantly following cataract surgery in the short term for the entire cohort, irrespective of the type of lens implanted. 17 Schmoll et al 18 looked at sleep-wake and cognitive reaction times and showed no difference between BFIOL or UVFIOL. The CHUKYO study was designed to evaluate blood pressure and sleep duration after IOL implantation during cataract surgery and to compare different types of IOL.…”

“…The SCN in turn regulate circadian biology throughout the body. 17,65 Ocular light input is required to synchronise the body clock to the environmental daynight cycle. 17 It has already been shown in a number of studies that in addition to improving vision, cataract surgery has been shown to lead to an improved sleep-wake pattern.…”

[17][18][19]66 This benefit is presumed due to the increased amount of light reaching the retina.…”

[17][18][19]66 This benefit is presumed due to the increased amount of light reaching the retina. Landers et al 66 carried out a cross-sectional study comparing the sleep quality of 31 individuals with UVB-IOL and 18 individuals with BFIOL.…”

“…15,16 There have been excellent comprehensive articles reviewing this subject in detail and a more recent metaanalysis by Zhu in 2012. [1][2][3][4][5] Since then more information has become available regarding the impact of the BFIOL on the sleep-wake cycle, 17,18 blood pressure, 19 mood, 20 and cognitive function 18 as well as early small studies looking at age-related macular degeneration (AMD) development. 21,22 Photoprotection and photoreception Transmittance and absorption properties of BFIOLs and UVFIOLs have been compared with each other, as well as to the natural crystalline lens.…”
