Abstract: 

Purpose: To report findings that could suggest an elliptical shape of the capsular bag.
Methods: Five eyes of three patients with axial length greater than 24 mm underwent phacoemulsification cataract surgery with plate?haptic multifocal toric intraocular lens (IOL) implantation oriented in the vertical meridian.
Results: In all cases, correct orientation of the IOLs was verified 30 minutes after surgery. After 24 hours, all eyes demonstrated unwanted rotation of the IOLs ranging from 15 to 45 degrees. The IOLs remained stable in the new position in all cases until adhesion of the capsular bag took place.
Conclusion: These observations could suggest that the perimeter of the capsular bag has an elliptical shape.
Therefore, the IOL tends to become fixated in a meridian of the capsular bag that best fits the diagonal diameter of the IOL.
