Efficacy of haptic sutured in-the-bag intraocular lens for intraocular lens-capsule complex stability: a comparison of three insertion methods.

ABSTRACT:

Aim

To evaluate the efficacy and stability of haptic sutured in-the-bag intraocular lens (IOL) in eyes with zonular instability.

Methods

A total 60 eyes of 60 patients were included in this retrospective cohort study. Postoperative stability in three groups [haptic sutured IOL in the bag, IOL in the bag insertion with haptics oriented toward areas of zonulysis, IOL with capsular tension ring (CTR) in the bag insertion] were compared according to the IOL insertion methods. To evaluate the IOL stability, the changes of anterior chamber depth (ACD), refraction, contraction of anterior continuous curvilinear capsulotomy (CCC) area, and tilt of IOL were compared.

Results

There was no significant difference in change of ACD (-0.04±0.01 mm in group of haptic sutured IOL, -0.07±0.01 mm in group of CTR insertion) and refraction (0.05±0.05 D in group of haptic sutured IOL, 0.37±015 D in group of CTR insertion) between the group of haptic sutured IOL in the bag and CTR insertion group. But in comparison of CCC contraction and IOL tilt, CTR insertion group showed less contraction (1.00%±0.52%) and less IOL tilt (2.66°±0.11°) than the group of haptic sutured IOL in the bag (6.32%±1.36%, 3.47°±0.11°, respectively). The CTR insertion group showed the least CCC contraction and the least tilt.

Conclusion

In eyes with zonular instability, the method of haptic sutured IOL in-the-bag shows comparable stability in ACD and refraction in comparison with IOL with CTR in the bag insertion. The method of IOL only in-the-bag insertion shows the largest contraction of CCC and the largest tilt of IOL.
