Exclusion Criteria

- Primary Outcome Measures
Name Time Method Evaluate the magnitude of intraocular lens rotation (in degrees) 6 months after implantation, through photographic records of the patient's eye and comparing it with the preoperative planning. It is expected to determine, with 80% probability, that the magnitude of postoperative lens rotation has an average of less than or equal to 1.5 degrees, which is clinically reasonable to be considered small, or within an acceptable limit for good lens operation.<br>
