Delivering the next generation of outcomes with new lens and corneal refractive technology

Yao Ke, MD, Hangzhou, China, and Ronald Yeoh, MD, Singapore, led a symposium during the 2017 Asia-Pacific Association of Cataract & Refractive Surgeons (APACRS) meeting in Hangzhou, China on optimizing outcomes with currently available premium lens and corneal refractive technologies. The faculty included Fam Han Bor, MD, Singapore, Edward Manche, MD, Palo Alto, California, and He Tian Geng, MD, Tianjin, China..

Optimizing SMILE

The centration of any refractive surgery is vital, said Jodhbir Mehta, MD, Singapore. Accurate centration reduces photic phenomena such as glare, halos, and induced higher order aberrations that can occur postoperatively. Experience with LASIK, Dr. Mehta said, has shown that accurate centration is achieved by several means—via faster lasers, greater accuracy with smaller spot sizes, and the use of eye trackers. There are also several options for centration: It can be done centering on the pupil, the visual axis, the corneal vertex or the coaxial sighted corneal light reflex. Some of these, he said, are easier and more well defined than others.
