LASIK for Astigmatism after Cataract Surgery

Question: I will be needing cataract surgery at some point and would like to know of use of LASIK following the IOL implants is option for correcting astigmatism rather than using one of the newer IOLs. And if so which is the better or at least more proven technology. My current prescription is RE +0.75-1.75 x 088 add +2.75 and LE PL-1.75 x 094 add+2.50

Answer: LASIK after Cataract Surgery to correct astigmatism is an option for those people who have residual astigmatism after their Cataract operation. Your current prescription indicates that you have preexisting astigmatism along with presbyopia-a common condition whereby the crystalline lens loses its ability to change focus causing you to have difficulty with near vision. It is possible to have a monofocal lens implant and NOT correct the preexisting astigmatism which would probably necessitate either wearing glasses or a second surgery-either LASIK Surgery or Limbal Relaxing Incisions (LRI) in order to see clearly at distance. A possible better solution might be to have a toric lens implant that would correct your astigmatism as part of the Cataract removal all in one procedure. However the decision to have a toric lens implant is based on several factors in addition to the prescription. If you are a good candidate for an astigmatism correcting lens implant (IOL) and you would not typically elect NOT to have one so as to require a second surgery such as LASIK. The best next step for you is to find a Cataract Surgeon who is also a top LASIK Surgeon who will provide an examination that includes some additional measurements including evaluation of the shape of your cornea and help you determine what the best options might be for you.
