Introduction

• Toric IOLs have been designed to compensate preop
  corneal astigmatism.

3
PURPOSE

• To assess efficacy, safety and optical quality of
  a premium lenses (Lentis Mplus Toric Oculentis,
  Berlin, Germany)
• to correct astigmatism, refraction,
• and also presbyopia.

4
METHODS

• Prospective study.
• Corneal astigmatism greater than 1 diopter
• 6 eyes (3 patients) received a Lentis Mplus Toric
  IOL
• Single piece, multifocal acrylic lens with and
  aspheric posterior surface.
• Multifocality archieved by a near sector in the
  lower IOL part.
• An individual correction of corneal astigmatism
  was also provided by this IOL.
• Patients underwent MICS through 1.8 mm clear
  corneal incision.

5
Pre and Post operative parameters

• Keratometry
• Subjective refraction
• Corneal Topography (Atlas 9000, Carl Zeiss
  Meditec)
• Corneal wavefront analysis and HOA (KR-1,
  Topcon)
• These parameters were collected before surgery
  and 3 months after.
• Uncorrected distance and near visual acuity was
  also determined.

6

• Oculentis calculator
• Using SRK-T formula and IOL Master biometry

7
6-months postoperative evaluation

• Slitlamp examination (stability, rotation?)
• Best-corrected visual acuity
• Subjective refraction
• Pupillometry
• Objective contrast sensitivities (OQAS,
  Visiometrics, Spain)
• Corneal Topography and corneal HOAs
• Total ocular aberrations measurement with
  hartmann-shack aberrometer

8
RESULTS

• Our results indicate that multifocal toric IOL
  implantation is a predictable option to correct
  preexisting corneal astigmatism.

9

• 6 Months postoperative non-corrected distance
  visual acuity ? mean value 9,4/10ème (between
  7/10ème and 12,5/10ème).
• Mean rotation IOL 5,2 /- 3,6 , between 0 and
  10.

CONCLUSION

• Good visual outcomes with uneventful multifocal
  toric implantation.
• Stable in time Few rotation at 6 months
  postoperatively.
• Predictable and reliable method for astigmatism
  correction in MICS technique
• Good intermediate and near vision at 6 months.
• Good predictive refractive error for distance
  vision.
