Recruitment & Eligibility

Status: Completed

Sex: Not specified

Target Recruitment: 25

Inclusion Criteria

Diagnosis of cataract in both eyes, having consented to and is planned to
undergo cataract surgery in both eyes, planned for implantation of a non-toric
monofocal IOL, a targeted refractive error of emmetropia, age of at least 18
years.

Exclusion Criteria

Any comorbidity that may significantly affect visual function and/or increase
straylight and/or prolong visual recovery after surgery, subjects with a
history of ocular surgery, subjects with an increased risk of complicated
cataract surgery, corneal astigmatism of >= 3 diopters

Study & Design

Study Type: Observational non invasive

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
<p>The primary outcome parameter is the amount of straylight, expressed as the<br /><br>logarithm of the straylight value (log[s]). </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Secondary study parameters are 1) (relative) pixel intensities of the cornea,<br /><br>the (pseudo)phakic lens, the posterior lens capsule, and any vitreous opacities<br /><br>in measurements with the Pentacam and the IOLMaster 700, 2) uncorrected<br /><br>distance visual acuity (UDVA), (best-)corrected distance visual acuity (CDVA),<br /><br>determined with ETDRS visual acuity chart and expressed as the logarithm of the<br /><br>minimum angle of resolution (logMAR), 3) refractive error by means of automated<br /><br>refractometry, expressed as spherical equivalent (SEQ) refraction and as<br /><br>defocus equivalent (DEQ) refraction, 4) lens position, expressed as anterior<br /><br>chamber depth. Anterior chamber depth is defined as the distance from the<br /><br>central anterior corneal epithelium to the anterior part of the lens, and 5)<br /><br>presence (and severity) of any opacities in the ocular structures in the slit<br /><br>lamp photographs. </p><br>
