Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
