Question:
I have high myopia—approximately -12 in both eyes—due to ROP. I have a rapidly progressing cataract in one eye and am planning to have it removed. If I had a monofocal lens put in for distance, how will I correct near vision since glasses will not be an option with such different vision needs in the two eyes?     

Answer:
Double vision would occur if the difference in the refractive power of the two eyes is greater than 3.00 diopters. If you have a monofocal IOL implanted for distance in one eye and you are -12.00 in the other eye (a 12.00 diopter difference), you would see double for distance and for near with spectacles. If you are able to wear a contact lens in the -12.00 eye, you will not have double vision for distance. That same contact lens would allow you to wear a pair of reading glasses over both eyes for near vision, also without double vision. Another option is to wear a contact lens in the -12.00 eye that corrects most—but not all—of your myopia, leaving you a little nearsighted in the operated eye. This would be a form of monovision whereby one eye is focused for distance and the other is focused for reading. Many people find this an excellent combination for distance and near vision. I suggest to talk to your ophthalmologist (Eye M.D.) who I am certain knows all about these options.
