Clinical Outcomes and Postoperative Optical Quality with Aspheric Preloaded IOL After 1.8 mm MICS BELLICAUD D, NOCHEZ Y, PISELLA M, CENSIER M, PISELLA PJ C.H.U. Bretonneau, Tours, France No financial disclosure
PURPOSE • To evaluate the visual outcomes and objective optical quality with the Quatrix® aspheric preloaded IOL in microincision cataract surgery (MICS). • Quatrix® IOL was inserted into a 1.8 mm injector cartridge for a peripheral injection at the edge.
METHODS • Prospective study. • 30 eyes of 25 patients with senile cataract underwent MICS through 1.8 mm clear corneal incision : implantation with Quatrix® • We compared this group to a control group : 20 eyes of 10 patients implanted with a micro-incision IOL : AcriSmart 36A® (Carl Zeiss Meditec, USA)
Quatrix Aspheric Preloaded IOL • The one-piece hydrophilic acrylic IOL features four haptics for a large contrast zone to prevent capsular folds. • This 11-mm lens has a suggested A-constant of 119.6, and requires a 2.8-mm incision. • This aspherical preloaded IOL Quattrix® was used : it was inserted into a 1.8 mm injector cartridge for a peripheral injection at the edge.
Post operative parameters : • Corneal Topography (Atlas 9000®, Carl Zeiss Meditec) • Placido disk technology • Axial and tangential curvature • Keratometry • We assess corneal HOA with corneal wavefront analysis • These parameters were collected before surgery and 6 months after.
Post operative parameters : • Objective Quality Analysis System® (Visiometrics, Spain). • 100% and 9% log-MAR best corrected visual acuity (BVCA), • Modulation Transfer Function (MTF), • Strehl ratio (SR) • Objective Index of Scattering (OSI)

CONCLUSION • Implantation of Quatrix® aspheric preloaded IOL during a 1.8 mm MICS was safe and effective. This IOL can be inserted through a 1.8 mm incision for a peripheral injection at the edge. • No astigmatism surgically induced. • It provided good refractive outcomes with good objective optical quality. • The quality of vision and the optical quality of this IOL are identical to another aspheric micro-incision IOL. However, strong stability in the capsular bag and rate of secondary capsular opacification must be taken into account on a significant follow-up period.
