Ladas Super Formula aims to improve refractive accuracy of cataract surgery

We have all seen it in our own patients: After a seemingly routine cataract surgery that is without complications, the patient ends up with a refractive miss. Even though we were aiming for a plano refraction, the patient is a diopter away from that. For a patient electing for cataract surgery alone, this is still a successful case because the patient was not electing for vision correction. But for those patients who are electing to pay out of pocket for treatment of astigmatism and a specific refractive outcome, being off by 1 D is unsatisfactory. We can fix this and achieve the plano result that we desire, but how did this happen in the first place?While lay people may think that the refractive surprise is the result of the “wrong” lens being put in the eye, this is actually a very unusual case. Certainly putting the lens for patient A into patient B is a serious medical mistake, but it is quite rare. Other errors such as not remembering to adjust the power when switching between IOLs with different A-constants are also infrequent. The error is in determining the IOL power and/or predicting the patient’s healing response, which determines the final resting position of the optic.
