Posterior Chamber Lens Implantation Techniques in Posterior Capsular Rupture

Abstract

Purpose

To evaluate posterior chamber lens implantation techniques and their results in patients in whom posterior capsular rupture and zonular dialysis arose during cataract operation.

METHODS

Forty-three cataractous eyes of 43 consecutive patients with complicated cataract operations such as posterior capsular rupture or zonular dialysis were accepted into this prospective study between November 1999 and January 2001. Intraocular lens implantation to ciliary sulcus was achieved without sutures in 19 cases (Group 1), with one suture from 12 o'clock quadrant in 14 cases (Group 2), and with two sutures from 3 to 9 o'clock quadrants in 10 cases (Group 3). Patients were followed up for 3 months after operation and evaluated for best-corrected visual acuity, refractive astigmatism, corneal edema, anterior chamber depth and inflammation, synechia at angle, intraocular pressure, lens tilt and decentration, intraocular hemorrhage, cystoid macular edema, and retinal detachment.

Results

There was no difference among groups in best-corrected visual acuity, refractive astigmatism, corneal edema, anterior chamber depth and inflammation, intraocular pressure, lens tilt and decentration, cystoid macular edema, or retinal detachment. Anterior chamber and vitreous hemorrhage and peripheral anterior synechia were significantly higher in Group 3 when compared with Group 1 (p=0.009, p=0.009, and p=0.004).

CONCLUSIONS

In all cases with posterior capsular rupture and zonular dialysis, different posterior chamber lens implantation techniques could be performed, beginning with the least invasive procedure suitable for the conditions with the least complications.
