Rotational Stability of 2 IOL Platforms
Narrative Responses:
Purpose
To study rotational stability of hydrophobic acrylic IOL with different haptic design.
Methods
Two different hydrophobic acrylic single piece IOL (860FAB and 77FAB, Medicontur, Hungary) were implanted after uneventful phacoemulsification. Photos wer taken in retroillumination at day 1, week 1, week 4 and month 3. These images were analyzed in Photoshop and rotaional stability were estimated.
Results
29 eyes with 860FAB and 38 eyes with 877FAB were analyzed. Majority were within 1° of rotation (24/29 eyes with 860FAB vs. 32/38 eyes with 877FAB). No IOL had more then 5° of rotation. No clinically significant diference was found between the two different haptic designs.
Conclusion
There was no difference in rotational stability during the first three postoperative months between the two types of haptic designs. Postoperative IOL rotation between day 1 and month 3 is minimal and capsular bag shrinkage does not cause severe rotation of hydrophobic acrylic IOL.
