Summary

The recently introduced toric V4c toric ICL (STAAR Surgical Company, Monrovia, CA, USA) has been designed with a 360-µm central hole to allow aqueous humor to flow without the need for an iridotomy. As far as the investigators certain, there have been not well-established prospective studies on the role of the V4c toric ICL for myopic astigmatism correction. Therefore, the present study aimed to investigate the clinical outcomes and rotational stability and to analyze factors that influence the rotational stability in V4c toric ICL implanted eyes prospectively.

Conditions

  • Myopic Astigmatism

Interventions

PROCEDURE

V4c toric ICL implantation surgery

The size and power of the V4c toric ICL were determined following the manufacturer's guidelines using a modified vertex formula. Emmetropia was the target refraction following surgery in all cases. Before surgery, three centration points were marked using the slit lamp while the patient, in sitting position, fixated on the center of the slit-lamp beam, which was narrowed as much as possible.
