Doctor DanB : Hello and thanks for your question. Are you available to chat?
Doctor DanB : Unfortunately, errors in calculation of the lens implant power do happen. Most of the time, approximately 90% of the time, the appropriate lens power is calculated such that the desired refractive state is reached. However, for numerous reasons such as an excessively long or excessively short eye, an eye that has had prior surgery or trauma, the measurements that are taken to determine the power of the lens implant sometimes are not as reliable as we would like. This sounds like what happened to you.
Could the calculation really be off so much that I wind up with near vision instead of distance vision?
Doctor DanB : For your other eye, presumably it has not had surgery or does not have other abnormalities that would make lens implant calculation difficult, I would not expect a refractive surprise such as one that you had with the first eye. Knowing that, I think it would be okay to get the toric implant in the fellow eye. What your doctor has offered does not sound fishy, but sounds like it was offered with good intentions to show that he or she is trying to have your best interests at heart.
Doctor DanB : Unfortunately, yes, a miscalculation could result in clearer near vision than far vision.
Knowing I had a prior retinal detachment, should the physician have used multiple devices or programs to take measurements in order to verify the individual results?
Doctor DanB : It is difficult to say from my end whether your surgeon should've use multiple means of measurements to calculate your lens implant. If, looking at the scans, there were abnormalities visible, that can and usually does prompt the surgeon to seek additional measurements to verify the first, but without looking at the scans and seeing a visible abnormality of the quality of the scans, I cannot say that he was wrong in not using additional measurement means.
PS - I don't know that he didn't use multiple measurements. Also I'm not looking for grounds for a lawsuit, but I'm just trying to feel comfortable in making the decision to proceed with the second eye. I think this covers all my questions.Thanks again. XXXXX
