BARCELONA — LASIK with advanced cyclotorsion compensation using the Schwind Amaris excimer laser is safe and predictable and yields superior visual outcomes, according to a presenter here.

"Results were achieved without applying any nomograms, and the 3-month follow-up time showed good performance of the system," Maria C. Arbelaez, MD, said at the European Society of Cataract and Refractive Surgeons meeting.
Dr. Arbelaez evaluated the intraoperative static and dynamic cyclotorsion components and the postoperative clinical outcomes of higher-order aberrations and contrast sensitivity in 50 aberrated eyes undergoing LASIK with advanced cyclotorsion control using the Schwind Amaris laser system. Treatments were planned with the Custom Ablation Manager software. Twenty eyes were treated with corneal wavefront, and 30 eyes were treated with aberration neutral profiles. LASIK flaps were cut using the LDV femtosecond laser (Ziemer) in all eyes.
Results indicated that the refractions and higher-order aberrations affecting contrast sensitivity were reduced to subclinical values without applying additional nomograms. Best corrected visual acuity improved in 42% of eyes, while 2% lost one line of BCVA.
Dr. Arbelaez said additional follow-up is necessary to evaluate long-term stability.
