New toric IOL has better results in terms of centration stability

MILAN — A new toric IOL for microincision surgery shows superior performance in ensuring centration stability, according to one surgeon.
Rotation and decentration are major issues with toric IOLs. Even the slightest axis misalignment has a significant negative impact on cylinder correction.

“Decentration leads to coma aberration and happens easily, particularly at the delicate stage of withdrawing the viscoelastic after implantation,” Scipione Rossi, MD, said at the OSN Italy meeting.
The Mini Toric Ready IOL (Sifi) has a four-point symmetric haptic design that facilitates self-centration and rotation by the surgeon in either direction for perfect alignment.
“Once the lens is positioned, the special copolymer material with enhanced adhesive properties and micro-roughness on the contact surface keeps the lens well anchored to the capsular bag. We have had the chance to see personally how firmly in place this lens remains, exactly to the point where it has been positioned, when we draw out the viscoelastic at the end of surgery,” Rossi said.
A multicenter study is currently ongoing in Italy, and preliminary 3-month results show a mean residual refractive astigmatism of 0.35 D and total wavefront cylinder close to zero.
A UBM study shows that the lens fits well in the capsular bag.
“This lens is going to give us great satisfaction,” Rossi said. – by Michela Cimberle
