Description of intervention(s) / exposure
We compared three different types of intraocular lenses (IOL), AcrySof MA60BM, Sensar AR40e, and the Rayner C-Flex 2. These lenses are intraocular, so participants will be wearing the lenses for wholelife. There are three different groups of participants who wear one type of lens only. The AcrySof MA60BM (Alcon Inc, Fort Worth, TX, USA) is a 3-piece hydrophobic acrylic IOL with flexible polymethyl methacrylate (PMMA) C-loop haptics with 10-degree angulation. Its overall length is 13.0 mm, with a biconvex optic having a diameter of 6.0 mm. The Sensar AR40e (Abbott Medical Optics, Santa Ana, CA, USA) is a 3-piece hydrophobic acrylic IOL with flexible PMMA C-loop haptics with 5-degree angulation. Its overall length is 13.0 mm, with a biconvex optic having a diameter of 6.0 mm. The Rayner C-Flex (Rayner Intraocular Lenses Limited, East Sussex, UK) is a 1-piece hydrophilic acrylic IOL. This lens has a plate-haptic configuration without angulation. It has a body diameter of 5.75 mm and overall length of 12.00 mm.

Overall duration of this observational study is 6 months
