Question: If multifocal contacts will not correct my vision will multifocal lens implants IOL's not correct my vision after cataract surgery? Also if I have astigmatism what are the advantages of using a toric lens version monovision lens to correct my vision during cataract surgery?
Answer: There is really minimal relationship between multifocal contact lenses correction and multifocal lens implant correction as their optical location and designs are quite different. You have two separate optical correction challenges-presbyopia which requires a near vision correction and astigmatism. There are currently no toric multifocal lens implants that would correct both presbyopia and astigmatism available in the United States.
However, your Cataract Surgeon could choose to correct the astigmatism with a Limbal Relaxing Incision (LRI) if you were set on having a multifocal lens implant for the near vision presbyopia correction. The other alternative is to use a monovision toric lens implant technique to achieve the concurrent astigmatic and near vision presbyopic correction. If you have astigmatism-especially 3-4 diopters of astigmatism-it ABSOLUTELY must be corrected if you do not wish to wear eyeglasses. For monovision it would be preferred to have a toric lens implant monovision rather than an aspheric lens implant with an LRI as it would provide better overall optical quality and stability.
