D. Brian Kim, MD, shares a modification of the Yamane scleral haptic fixation technique to implant a three piece IOL when there is little or no capsular support. The haptic material on the EC-3 Intraocular Lens (Carl Zeiss) is particularly helpful in these cases because it resists deformation and breaking.

Wonderful tips Dr Brian Kim. Is it worth marking the haptic tip just to ensure symmetrical bulbs. I read somewhere that cauterizing up to 0.3mm of the tip will produce a just nice enough bulb anchoring in the sclera. What are your thoughts on this?

Thank you for the question. Are you referring to marking the haptic after it has been externalized? I worry about exposing the eye to the ink and potential toxicity. I do not believe it is helpful. As long as the scleral marks are symmetrical and the needle passes follow your marks, you should get good centration. If it's not well centered, you can cut one haptic to make it even then cauterize. If it is too decentered, then haptic may need to be pulled back into the eye and redocked and retunneled through the sclera. Best wishes.

nice step by step video. better than glued IOL A QUESTION, IN AN OF THESE CASES HAVE U EVER ENCOUNTERED THE HAPTIC TO DROP BACK SECOND, HOW MUCH IS THE DECENTRATION AND TILT NOTED IN VARIOUS CASES

Hi Frederico, thanks for the question. Honestly I haven't tried 1mm but intuitively I think 2mm is better. The longer the scleral tunnel, the better the haptics will be supported by sclera and less likely for leakage from the needle tract. Of course these are theoretical considerations since I have not done it with 1mm. More importantly, the question I have is why 1mm? Doing 2mm is not that much more difficult, IMO. I hope this helps.

Great technique! Congrats. One question: regarding the insertion of the needle in each side, do you think instead of 2mm apart from C to A // B to D it would make any difference doing a 1mm scleral tunnel?
