This document discusses a study examining the use of consistent preoperative marking and transitional conic cylinder intraocular lenses (IOLs) to improve results of astigmatism correction during cataract surgery. 79 eyes underwent cataract surgery with implantation of transitional conic surface IOLs. A preoperative topographic limbus marking was performed for alignment of the IOLs. Post-operative evaluation found the consistent marking and conic IOLs provided good results in correcting astigmatism and accurate IOL power calculation. The study concludes more effective preoperative marking and transitional conic IOLs can improve refractive outcomes of cataract surgery for astigmatism.

28. 1. Improve intraoperative alignment of toric IOLS (“consistent”)
2. Using Transitional Conic Toric Surface IOLS
3. Verifying affidability of conic toric IOLs calculation (end point)

29. Method
79 eyes underwent cataract surgery ( 2-4 density) by same
surgeon Dr.Nicola Canali MD
we develop a «consistent» marking of refractive axis
Patients received slit lamp limbus marking
A preoperative corneal topographic limbus marking was
performed as repere
Correction of axis of implantation was practiced referring
to repere
The surgery took place with the Centurion
phacoemulsification in peristaltic mode
All eyes were implanted a Ophtec ®Precizon Tooric IOL,
with transitional conic surface, hydrophilic Acrylic,
aberration 0 Ꙡm, 2,2 incision
A pre-operative, post-operative, 1-month refraction
evaluation was made

46. A more effective marking of the corneal before surgery can achive good
results in correction of astigmatism
Conical transition IOLs assure perfect calculation in power due to online
calculator.
Visual digital intraoperative alligment of axis could improve refractive
results
Intraoperative aberration could reduce mistakes
