“Dry eye can make your biometry measurements very inaccurate.

“Anybody who’s doing cataract surgery needs to be aware of corneal surface disease,” states Dr. Bakewell, who adds that he’s had some patients forget to tell him about refractive surgery performed 15 or 20 years ago. “The aberrometry is great, but you obviously also need a good examination at the slit lamp,” continues Dr. You know how much spherical aberration patients have, and that dictates what lens you’re going to put in the eye if you’re going to try and balance that for the best optical outcome. I can look at that and usually tell if they’ve had myopic or hyperopic LASIK just from looking at the aberrometer. “We do an OPD using the Nidek system for aberrometry. Bakewell, MD, FACS, partner at Fishkind, Bakewell & Maltzman Eye Care in Tucson, Ariz., and adjunct associate professor of ophthalmology at the University of Utah. “Anybody that comes into our office for an exam gets an aberrometry scan,” says Brock K. If there’s anything that would show up later, in the postop results, we also want to know ahead of time.” “Everybody having cataract surgery will get OCT, and they will get evaluation of the thickness of the cornea, so that if there is underlying Fuchs’ or anything that would be an issue at the time of surgery, we can take extra care with the eye. Sayegh says these measures help to reveal any pathology ahead of time. It also allows surgeons to enter spherical and toric data simultaneously and features multiple computation modes, including the Hybrid function, which runs multiple formulas and selects the best one.ĭr. The UniversIOL Calculator’s database includes a vast array of lenses. Another thing we do is OCT of the retina for all patients. For the measurement of the K value, we use at least three methods. We do both every time, for every patient. We do partial coherence interferometry using the IOLMaster for axial length, and we do ultrasound. “We have a routine that applies to all eyes identified as being particularly exceptional,” he says. Samir Sayegh, MD, PhD, FACS, of the Eye Center in Champaign, Ill., also considers a meticulous workup fundamental to a good refractive outcome. I also do an OCT of the macula to make sure there is no pathology.” “I use the IOLMaster 700, the Cassini and the iTrace on every patient. Dee Stephenson, MD, FACS, president of the American College of Eye Surgeons, associate professor at University of South Florida College of Medicine in Tampa and CEO/CFO of Stephenson Eye Associates. “I can have a long eye, a short eye or a post-LASIK eye, but the most important thing I do is give them all the same thorough preoperative workup,” emphasizes P.

This article provides insights from seasoned cataract surgeons about how to maximize your outcomes and includes brief discussions of specific types of challenging eyes. 1 Today, outcomes within half a diopter or less of target are attainable in most normal eyes, but some cases continue to present challenges. Harold Ridley (1906-2001), who implanted the first intraocular lens in 1949, lived to see cataract surgery evolve into a true refractive procedure, undergoing IOL implantations himself in 19.
