A 61-year-old man presented with gradual blurring of vision and glare in both eyes for a couple of years, with worsening of the vision in his right eye over the past 2 months. He had no medical history of note.
On clinical examination, his visual acuities were 20/80 in the right eye and 20/30 in the left eye, uncorrected. The cornea was clear, and the anterior chamber (AC) was deep in both eyes. He had bilateral mild nuclear sclerosis with round central onion-ring–like posterior opacities. The opacities measured approximately 2 mm in diameter and were marginally larger in the right eye than in the left eye (Figure 1;)

). In addition, there were 2 curvilinear lines across the right posterior capsule (PC), one of which passed across the lens opacity (Figure 2Figure 2.: Retroillumination view of the right cataract showing 2 curvilinear lines in the area of the posterior lens opacity.
). Fundus examination was normal in both eyes, and the vitreous was clear. Optical coherence tomography (OCT) of the macular and optic nerve in both eyes was normal. The endothelial cell count in both eyes exceeded 2000 cells/mm2.
He had been told by a previous ophthalmologist to have bilateral cataracts and was now keen for surgery starting with the right eye. He works as a manager in a large company and is an avid golf player. He is emmetropic and wears spectacles for near work. Optical biometry using predicated posterior corneal astigmatism did not recommend a toric intraocular lens (IOL). He had done his internet research on IOL options and requested trifocal IOLs.
What is your surgical plan for right cataract removal? Explain which IOL you would choose to implant.
