This patient is a young man, in his 40s, with a history of cataract development over the last few years. It is at the point where the best corrected vision in both eyes is 20/200 and he certainly needs cataract surgery. There is also a history of anisometropia, hyperopia, astigmatism, and amblyopia. This eye is his better seeing eye, which used to correctable to 20/20 vision with a refraction of +4.00 -1.50 x 100 (steep axis 10 degrees). The other eye has a history of amblyopia due to anisometropia with a prior refraction of +7.00 -1.50 x 90 (steep axis 180) which yielded 20/50 vision. In this video, we are operating on his better seeing eye (the eye without amblyopia) and we are implanting a toric extended depth of focus IOL of a power of +25.0 to yield a perfect plano refraction. The other eye requires a spherical IOL power of +29.0, but that is not available in the EDOF design. So how should you proceed?
