Conditions
Interventions
With cataract surgery, the patient*s opacified lens is removed and replaced
with a clear artificial IOL. The intervention in the present study consists of
implanting a different, albeit very compara

Eligibility
Age
18 Years to 99 Years
Inclusion criteria
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
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
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome parameter is the amount of straylight, expressed as the logarithm of the straylight value (log[s]). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary study parameters are 1) (relative) pixel intensities of the cornea, the (pseudo)phakic lens, the posterior lens capsule, and any vitreous opacities in measurements with the Pentacam and the IOLMaster 700, 2) uncorrected distance visual acuity (UDVA), (best-)corrected distance visual acuity (CDVA), determined with ETDRS visual acuity chart and expressed as the logarithm of the minimum angle of resolution (logMAR), 3) refractive error by means of automated refractometry, expressed as spherical equivalent (SEQ) refraction and as defocus equivalent (DEQ) refraction, 4) lens position, expressed as anterior chamber depth. Anterior chamber depth is defined as the distance from the central anterior corneal epithelium to the anterior part of the lens, and 5) presence (and severity) of any opacities in the ocular structures in the slit lamp photographs. | — |
