E W MEETING REPORTER 162 March 2014 formula, for hyperopic refractive errors, the spherical equivalent is multiplied by 1.5 to calculate the p roper piggyback IOL power, and for myopic refractive errors, the spheri- cal equivalent is multiplied by 1.2 to calculate the necessary myopic piggyback IOL power. P reoperative IOL factors Preoperative factors are important to consider when deciding whether it is a good idea to implant an IOL and which IOL to use. Tal Raviv, MD, New York, discussed factors to con- sider. Preoperative factors are patient selection, IOL selection, expectation management, preoperative testing, a nd a clinical exam. Dr. Raviv said that it's both a science and art form to balance these factors. Preoperative testing includes looking at factors like optical biometry, corneal topog- raphy, keratometry, eye dominance, OCT, and pupil size. He covered the importance of managing patient expectations. Refractive cataract surgery requires a more thorough and meticulous preoperative evalua- tion, surgical planning and surgical execution, Dr. Raviv said. New tech- nologies such as the femtosecond laser can help achieve this. He added that it's important to target and hit emmetropia, which will make most patients happy. Use all tools avail- able to achieve this, he said, and be comfortable handling complications and uncommon cases. MIGS and changes in glaucoma surgery Robert Noecker, MD, Fairfield Conn., was first to speak on a panel discussion about glaucoma. He said there is a changing mindset in the treatment of the disease. There has been a lot learned from both cataract and refractive surgery, and microinvasive glaucoma surgery (MIGS) is similar to some of these procedures. There have been a num- ber of developments in devices and techniques, including the micro-by- pass stent and devices to access the suprachoroidal space. Cataract sur- gery alone is sometimes beneficial to IOP control in glaucoma patients, but IOP management is essential, Dr. Reporting live from the ASCRS ReACT program in New York, March 1, 2014 Sponsored by 160-163 MR ReACT_EW March 2014-DL_Layout 1 3/6/14 4:27 PM Page 162
