[Fixation of an intraocular lens using reverse optic capture with haptic tuck for intraoperative posterior capsule rupture]

Exact positioning and optimal axial alignment are mandatory to achieve satisfactory postoperative refractive results after implantation of a toric or presbyopia correcting intraocular lens (IOL). Posterior capsule rupture can preclude stable capsular fixation. In such cases, reverse optic capture with haptic tuck results in stable fixation of the lens with respect to centering, rotation and axial position. Only the haptics are positioned in the capsule, behind the anterior capsulorrhexis. The optic remains in the sulcus; thus, the lens is fixed in the rhexis, providing long-term stability despite the presence of posterior capsule rupture.

[Visual rehabilitation of patients with large post-traumatic defects of the anterior eye segment through iris-lens diaphragm implantation]

The diversity of methodological approaches and lack of pathogenetically reasonable tactics for patients with combined ocular injuries became the basis for the development and systematization of surgical rehabilitation stages of patients, in whom post-traumatic cataract is combined with post-traumatic aniridia and corneal scarring.

AIM

to construct a visual rehabilitation approach to patients with post-traumatic defects of the anterior eye segment following optical-reconstructive surgery that involved implantation of an iris-lens diaphragm (ILD).

MATERIAL AND METHODS

We have analyzed 80 reconstructive cases with ILD implantation in patients with post-traumatic aniridia and corneal damage. These patients constituted the first study group (Group 1). We have also investigated 58 eyes with residual ametropy and stable visual function 1 year after ILD implantation before and after conducting a laser keratorefractive surgery. These patients were assigned to the second study group (Group 2).

RESULTS

Rehabilitation approach to patients after anterior segment injuries that has been proposed allows to achieve high clinical and functional results and reduce the risk of intra- and postoperative complications.

CONCLUSION

The proposed approach to patients after optical-reconstructive surgery with iris-lens diaphragm implantation followed by keratorefractive surgery is an effective method of visual rehabilitation of anterior eye segment post-traumatic defects.
