Clinical Trial Summary
The purpose of the present study was to compare the clinical outcomes such as visual
function, refraction errors and visual quality of patients undergoing cataract surgery with
implantation of two different models of diffractive trifocal IOLs: RayOne Trifocal (Rayner
IOL, Ltd.) and AcrySof IQ PanOptix (Alcon Laboratories, Inc.) IOL.
Description:
Cataract is affecting over 95 million people worldwide and remains the leading cause of
vision impairment and blindness. Cataract surgery is an effective method for restoring visual
acuity (VA). With the advancement of cataract surgery technique and intraocular lenses (IOL)
technologies, expectations of patients from cataract surgery have good vision at distance and
near ranges without using spectacles. The standard IOLs design were monofocal, which offered
only fixed focal distance. One of the main factors for dissatisfaction after monofocal
pseudophakic eyes is lack of accommodation. Previous studies demonstrated that this problem
can be resolved by using diffractive trifocal IOLs. Diffractive trifocal IOLs provide
effective near, intermediate and distance visual restoration, and has been widely used in
patients who want to achieve spectacle independence after surgery. However, some possible
optical side effects of trifocal IOLs have been reported, including halos and other
dysphotopsias, reduced contrast sensitivity (CS), glare disability, which can significantly
affect visual quality and patient satisfaction. The purpose of the present study was to
compare the clinical outcomes such as visual function, refraction errors and visual quality
of patients undergoing cataract surgery with implantation of two different models of
diffractive trifocal IOLs: RayOne Trifocal (Rayner IOL, Ltd.) and AcrySof IQ PanOptix (Alcon
Laboratories, Inc.) IOL.
