  • 1. Is LASIK for Astigmatism Safe after Cataract Surgery?Cataract surgery is a well known and popular procedure for older patients who suffer from visionloss after cataracts. Those familiar with LASIK surgery know that it is possible to have cataractsafter LASIK. What some don’t know is if LASIK is possible after cataract surgery Las Vegaseye doctors say that it is possible.LASIK after Cataract Surgery to correct astigmatism is an option for those people who haveresidual astigmatism after their Cataract operation. Your current prescription indicates that youhave preexisting astigmatism along with presbyopia-a common condition whereby the crystallinelens loses its ability to change focus causing you to have difficulty with near vision. It is possibleto have a monofocal lens implant and NOT correct the preexisting astigmatism which wouldprobably necessitate either wearing glasses or a second surgery-either LASIK Surgery or LimbalRelaxing Incisions (LRI) in order to see clearly at distance. A possible better solution might be tohave a toric lens implant that would correct your astigmatism as part of the Cataract removal allin one procedure. However the decision to have a toric lens implant is based on several factors inaddition to the prescription. If you are a good candidate for an astigmatism correcting lensimplant (IOL) and you would not typically elect NOT to have one so as to require a secondsurgery such as LASIK. The best next step for you is to find a local Las Vegas Cataract Surgeonwho is also a top Las Vegas LASIK Surgeon who will provide an examination that includessome additional measurements including evaluation of the shape of your cornea and help youdetermine what the best options might be for you.Astigmatism and Toric IOL’s: Astigmatism is a very common imperfection of the eye and ispresent when the cornea is not spherical like a basketball. An asymmetrically curved object, suchas a football, is said to have a “toric” shape. When a cornea (the front curved surface of the eye)is toric, light rays passing through it do not focus to a single point. The result is “astigmatism”(Greek: not to a point). Glasses and contacts can be made in toric shapes to compensate for theimperfect curvature of the cornea. Likewise, a toric IOL can be implanted instead of sphericalone to neutralize astigmatism of the cornea, thereby providing better focusing without glassesthan spherical IOLs. In this way, astigmatism can be reduced or eliminated at the time of cataractsurgery. If you have a significant degree of astigmatism, this IOL option may be discussed withyou.The use of a toric IOL necessitates additional specific measurements, planning, surgicalexecution and post-operative considerations not required when implanting traditional spherical
  • 2. IOLs. As Medicare and most other insurance companies do not provide payment for the surgicalcorrection of astigmatism, patients are responsible for payment of these non-covered services.Toric IOLs, like toric eyeglasses, must be oriented correctly within the optical system of the eyeto improve astigmatism maximally. It is possible, although unlikely, that a toric IOL may shift inposition during the first few weeks following implantation, since it takes some time for the tissueinside the eye to firmly affix an IOL in position. In the case of significant IOL shift andreduction in vision, a second brief procedure to reposition the IOL may be necessary a fewweeks after implantation.
