Cataract Surgery and IOLs

A 58-year-old woman is scheduled for cataract surgery. She has a history of age-related macular degeneration (AMD) with best-corrected visual acuity of 6/18 in the operative eye. Which investigation is most appropriate to assess whether cataract removal will improve her postoperative vision?

A 68-year-old man with dense nuclear sclerotic cataract in the right eye presents for cataract surgery. Preoperative biometry shows axial length 23.5 mm, keratometry 44 D, and anterior chamber depth 2.8 mm. During phacoemulsification, the nucleus is noted to be very hard and the phaco time exceeds 3 minutes. Intraoperatively, there is a posterior capsular rupture with vitreous loss. What is the most appropriate next step in management?

A 72-year-old woman with a history of acute angle-closure glaucoma (successfully treated with laser peripheral iridotomy 2 years ago) now presents with a mature cataract in the same eye and visual acuity of 6/60. She is keen for cataract surgery. Anterior chamber depth is shallow. Intraocular pressure is 14 mmHg on no medications. What is the most appropriate next step?

Which of the following IOL materials has the highest refractive index and therefore allows the thinnest lens design?
