Precisely measuring your scleral entry points is critical to center the IOL optic when you are performing Yamane intra-scleral haptic fixation (ISHF). If the initial starting points are not 180 degrees apart then the IOL will be decentered. Similarly, if one side has a scleral path that is different from the other it can result in an off-center optic or even IOL tilt. And even if you do all of the above accurately but you cauterize one haptic tip more than the other, the IOL will end up malpositioned. Our guest surgeon today has very specific guidelines and precise measurements for ensuring that your Yamane ISHF IOL is beautifully centered. We also remind you of a previous video which showed how to use this to your advantage to re-center an IOL.
