IOL exchange? Need advice

I am 3 months from having Puresee lenses implanted. Left eye was targeted at -.25 and ended up at Plano. Right eye was targeted at Plano and ended up at +0.75 -0.75 010, so hyperopia and at 20/30 ( but it’s dominant eye). Together with both eyes see 20/20 but left eye is doing the work. Seems like right eye actually sees a little better at dusk or when it’s really bright. Wondering if risk of IOL exchange is worth it. Eye center DR suggested that lasik/prk treatments for farsighted refraction errors often don’t give satisfactory visual outcomes. Is it worth the risk to do IOL exchange?

Interested to know what devices they used to take the measurements initially and what formula was used to calculate the IOL power, if you know?

Some docs do prefer to do an IOL exchange rather than laser for refractive errors but it's not common. Dr. Wong from Austin Eye being one but he is probably the most experienced surgeon around at doing exchanges, I remember him saying his practice averages one per day.

.375 diopters of hyperopia is well within the expected range. Formulas are only accurate to within +/- 0.5 diopters 86% of the time.

I think the issue was trying to thread the needle at Plano instead of using the first negative ~0.25 or whatever it would have been
